Derad Network: The Crypto Project That's Taking Aviation to New Heights https://www.derad.net/

Hey Tumblr fam, let's talk about something wild: a blockchain project that's not just about making money, but about making the skies safer. Meet Derad Network, a Decentralized Physical Infrastructure Network (DePIN) that's using crypto magic to revolutionize how we track planes. If you're into tech, aviation, or just love seeing Web3 do cool stuff in the real world, this one's for you. Buckle up-here's the scoop.

What's Derad Network?

Picture this: every plane in the sky is constantly beaming out its location, speed, and altitude via something called ADS-B (Automatic Dependent Surveillance-Broadcast). It's like GPS for aircraft, way sharper than old-school radar. But here's the catch-those signals need ground stations to catch them, and there aren't enough out there, especially in remote spots like mountains or over the ocean. That's where Derad Network swoops in.

Instead of waiting for some big corporation or government to build more stations, Derad says,"Why not let anyone do it?" They've built a decentralized network where regular people-you, me, your neighbor with a Raspberry Pi-can host ADS-B stations or process flight data and get paid in DRD tokens. It's a community-powered vibe that fills the gaps in flight tracking, making flying safer and giving us all a piece of the action. Oh, and it's all locked down with blockchain, so the data's legit and tamper-proof. Cool, right?

How It Actually Works

Derad's setup is super approachable, which is why I'm obsessed. There are two ways to jump in:

Ground Stations: Got a corner of your room and a decent Wi-Fi signal? You can set up an ADS-B ground station with some affordable gear-like a software-defined radio (SDR) antenna and a little computer setup. These stations grab signals from planes flying overhead, collecting stuff like "this Boeing 737 is at 30,000 feet going 500 mph." You send that data to the network and boom, DRD tokens hit your wallet. It's like mining crypto, but instead of solving math puzzles, you're helping pilots stay safe.

Data Nodes: Not into hardware? You can still play. Run a data processing node on your laptop or whatever spare device you've got lying around. These nodes take the raw info from ground stations, clean it up, and make it useful for whoever needs it-like airlines or air traffic nerds. You get DRD for that too. It's a chill way to join without needing to turn your place into a tech lab.

All this data flows into a blockchain (Layer 1, for the tech heads), keeping it secure and transparent. Derad's even eyeing permanent storage with Arweave, so nothing gets lost. Then, companies or regulators can buy that data with DRD through a marketplace. It's a whole ecosystem where we're the backbone, and I'm here for it.

DRD Tokens: Crypto with a Purpose

The DRD token is the star of the show. You earn it by hosting a station or running a node, and businesses use it to grab the flight data they need. It's not just some random coin to trade—it's got real juice because it's tied to a legit use case.The more people join, the more data flows, and the more DRD gets moving. It's crypto with a mission, and that's the kind of energy I vibe with.

Why This Matters (Especially forAviation Geeks)

Okay, let's get real-flying's already pretty safe, but it's not perfect. Radar's great, but it's blind in tons of places, like over the Pacific or in the middle of nowhere. ADS-B fixes that, but only if there are enough stations to catch the signals.Derad's like, "Let's crowdsource this." Here's why it's a game-changer:

Safer Skies: More stations = better tracking. That means fewer chances of planes bumping into each other (yikes) and faster help if something goes wrong.

Cheaper Than Big Tech: Building centralized stations costs a fortune. Derad's DIY approach saves cash and spreads the love to smaller players like regional airlines or even drone companies.

Regulators Love It: Blockchain makes everything transparent. Airspace rules getting broken? It's logged forever, no shady cover-ups.

Regulators Love It: Blockchain makes everything transparent. Airspace rules getting broken? It's logged forever, no shady cover-ups.

Logistics Glow-Up: Airlines can plan better routes, save fuel, and track packages like champs, all thanks to this decentralized data stash.

And get this-they're not stopping at planes.Derad's teasing plans to tackle maritime tracking with AlS (think ships instead of wings). This could be huge.

Where It's Headed

Derad's still in its early ascent, but the flight plan's stacked. They're aiming for 10,000 ground stations worldwide (imagine the coverage!), launching cheap antenna kits to get more people in, and dropping "Ground Station as a Service" (GSS) so even newbies can join. The Mainnet XL launch is coming to crank up the scale, and they're teaming up with SDR makers and Layer 2 blockchains to keep it smooth and speedy.

The wildest part? They want a full-on marketplace for radio signals-not just planes, but all kinds of real-time data. It's ambitious as hell, and I'm rooting for it.

Why Tumblr Should Stan Derad

This isn't just for crypto bros or plane spotters-it's for anyone who loves seeing tech solve real problems. Derad's got that DIY spirit Tumblr thrives on: take something niche (flight data), flip it into a community project, and make it matter.The DRD token's got legs because it's useful, not just a gamble. It's like catching a band before they blow up.

The Rough Patches

No flight's turbulence-free. Aviation's got rules out the wazoo, and regulators might side-eye a decentralized setup. Scaling to thousands of stations needs hardware and hype, which isn't instant. Other DePIN projects or big aviation players could try to muscle in too. But Derad's got a unique angle-community power and a solid mission—so I'm betting it'll hold its own.

Final Boarding Call

Derad Network's the kind of project that gets me hyped. It's crypto with soul, turning us into the heroes who keep planes safe while sticking it to centralized gatekeepers. Whether you're a tech geek, a crypto stan, or just someone who loves a good underdog story, this is worth watching.

Derad's taking off, and I'm strapped in for the ride.What about you?

[mariacallous]

Above the bar at a small brewpub in Užupis, a hip neighborhood in Vilnius, Lithuania, hangs a portrait of a Madonna-like saint cradling a weapon—something between a rifle, a bazooka, and a 5G antenna.

The caption below reads: “Saint EDM4S.”

EDM4S—or Electronic Drone Mitigation 4 System—is a portable electronic-warfare weapon from Lithuania. Point the EDM4S at a hovering uncrewed aerial vehicle (UAV) and pull the trigger: The drone should lose contact with its operator and fall inertly from the sky.

Hundreds of EDM4S systems have been donated to Ukraine over the past two years. They are just one weapon in an unseen, and under-appreciated, battle for control of the electromagnetic spectrum. Powering this battle is a furious arms race. Ukraine and its allies on one side, Russia on the other. Both sides are trying to innovate better ways to spoof, jam, and disrupt enemy communications, particularly drones, while simultaneously working to harden their own systems against hostile signals.

This is electronic warfare. In late 2023, Kyiv identified winning the upper hand in this battle as one of its key priorities. With Russia steadily advancing across eastern Ukraine, the need to gain control of the electromagnetic space—and the skies—has only grown more important. Regardless of how this war unfolds in 2025, Ukraine has already changed electronic warfare forever.

Fighting to Electromagnetic Stalemate

Electronic warfare, or EW, has been a part of human conflicts for more than a century. Soon after radios were deployed to the battlefield, soldiers realized that sending bursts of static over a frequency could disrupt the enemy’s ability to communicate. But it wasn’t until World War II that EW really came into its own.

Early in WWII, the British were desperately trying to recapture control over their skies in the Battle of Britain. While British dogfighters grew steadily better at downing incoming Luftwaffe bombers, the Germans slowly moved their raids to the cover of darkness. This prompted a perplexing mystery for the British: How were the Germans so good at flying to their targets in the dead of night?

A young British scientist solved the mystery when he discovered a clue in the wreckage of a downed bomber. The plane’s landing assistance system, which used radio waves to measure the plane’s relative distance to the runway, had been improved so dramatically that it was being used as a rudimentary navigation device. Operators on the ground in Germany and occupied France would emit long, narrow bands of radio signals over British skies: The target factory or town could be found where the two beams coincided.

Armed with this information, the English raced to build their own radio and relay stations, broadcasting their own radio beams into the skies to confuse the incoming German pilots.

Thus began the Battle of the Beams. The Germans refined and upgraded its ability to broadcast and receive signals in British airspace, while the United Kingdom raced to detect and disrupt those signals. It set the pace of EW fights for a century to come.

Today, the electromagnetic space is much more complicated: Different types of signals are broadcast straight across the electromagnetic spectrum, from radar to GPS and GLONASS, to cellular signals. At any given moment, a soldier, UAV, fighter jet, or cruise missile could be sending and receiving a variety of different signals.

With that, militaries have raced to find new ways to jam, intercept, and even spoof those signals. One nation may issue new encrypted radios to its forces, prompting a rival country to develop more powerful radios to flood those channels with static. Recent decades have also seen radar and radio used to detect artillery launches and triangulate their exact position, allowing counter-battery systems to hit the source of fire. Fighter jets, in particular, have developed some of the most advanced onboard radio and radar systems for communications, EW, and counter-EW.

Throughout the Cold War, NATO and the Soviet Union were locked in a fierce battle to obtain even a marginal advantage over the other in this EW fight. That dynamic has driven some anxiety. A 2017 report commissioned by Estonia’s military took stock of Russia’s EW capabilities and warned that, should Moscow invade NATO’s eastern flank, it could likely knock out communications across a huge swath of the Baltics, thereby “negating advantages conferred on the Alliance by its technological edge.”

It wasn’t until Russia’s full-scale invasion of Ukraine in February 2022 that the world got to see the extent of Russia’s EW prowess. And it was a dud.

“Russian EW was a no-show,” wrote Bryan Clark, director of the Center for Defense Concepts and Technology at the Hudson Institute, in a July 2022 analysis for IEEE Spectrum.

Moscow had spent years planning for a major war with NATO, designing its EW systems to interfere with the onboard systems of advanced fighter jets and to jam the targeting computers of advanced ballistic missiles. Instead, it found itself in a war against fast-moving defenders making ample use of off-the-shelf UAVs.

Russia’s systems were “not very mobile, not very distributed,” Clark tells WIRED. Their relatively small number of big systems, Clark says, “weren’t really relevant in the fight.”

Moscow’s strategy assumed there would be a relatively static battlespace. Along the front, they would deploy the Infauna, a heavily armored vehicle that targets radio communications. Further out, around 15 miles from the front lines, they would send the Leer-3, a six-wheeled truck capable of not only jamming cellular networks but of intercepting communications and even relaying SMS to nearby cell phones. Even further out, from a range of about 180 miles, the fire-truck-sized Krasukha-4 would scramble aerial sensors.

“When you get close to the front, you get electronic weather,” Clark says. “Your GPS won’t work, your cell phone won’t work, your Starlink won’t work.”

This electromagnetic no-man’s-land is what happens when you “barrage,” Clark explains. But there’s a big trade-off, he says. Jamming across the spectrum requires more power, as does jamming in a wider geographic area. The more power a system has, the bigger it must be. So you can disrupt all communications in a targeted area, or some communications further afield—but not necessarily both.

Move Fast and Jam Things

Russia’s military was marred, early in the war, by bad communication, worse planning, and a general sluggishness in adapting. Even still, it had a big head start. “Unfortunately, the enemy has a numerical and material advantage,” a representative for UP Innovations, a Ukrainian defense tech startup, tells WIRED in a written statement.

So Ukraine developed two complementary strategies: produce a large volume of cheaper EW solutions, and make them iterative and adaptable.

Ukraine’s Bukovel-AD anti-drone system, for example, fits comfortably on the back of a pickup truck. The Eter system, the size of a suitcase, can detect the jamming signals from Russian EW systems—allowing Ukraine to target them with artillery. Ukrainian electronic warfare company Kvertus now manufactures 15 different anti-drone systems—from drone-jamming backpacks to stationary devices that can be installed on radio towers to ward off incoming UAVs.

When the full-scale war began in 2022, Kvertus had one product: a shoulder-mounted anti-drone gun, like the EDM4S. “In 2022, [we were producing] tens of devices,” Yaroslav Filimonov, Kvertus’ CEO told me when we sat down in his Kyiv offices this March. “In 2023 it was hundreds. Now? It’s thousands.”

“Our advantage is that we have many clever people and clever engineers, and we have our own research and development department,” Filimonov says. “Our reaction for different changes on the front line is very fast.”

That’s because Kvertus dispatches its staff to the front lines to see how things are working—or not. EW operators constantly send back reports on which parts of the spectrum are being bombarded by Russia, and which parts of the spectrum Russian forces are inclined to use. Military tech firm Piranha-Tech’s systems are now capable of downing drones from more than a kilometer away, from a height of roughly 500 meters.

UP Innovations was financed as part of Business Springboard, a government-led initiative to finance veteran-run businesses in Ukraine. Being veteran-run means they have firsthand knowledge of what their soldiers actually need. UP has been working on special helmet pads with fabric that works as a Faraday cage to protect the wearer’s radios from jamming.

“Today, every unit has specialists working with tactical radio electronic warfare devices,” Yuriy Momot, deputy CEO of Piranha-Tech, tells WIRED. “There is no operation that goes without the use of radio electronic warfare. As we talk, one of their anti-drone guns sits on the table between us. Just the day before, guns just like this one helped one unit shoot down a dozen enemy drones—including one carrying a grenade.

The early versions of these anti-drone guns caused some skepticism that they would ever be much use in the real world—Russian military analysts mocked them as cheap toys. That mockery has long since faded, however. In recent months, plywood shacks have been popping up on high-rise rooftops in Moscow and St. Petersburg. They house a couple of Russian soldiers, a shotgun, an assault rifle, and a Russian-made anti-drone gun.

But when it comes to defending themselves, Kyiv has opted for a very apropos solution: a decentralized, distributed EW solution.

For more than two years, Ukraine has faced an onslaught of missiles, drones, and glide bombs—all equipped with onboard communications and radar designed to overcome Ukraine’s air defense systems. In recent months, the Iranian-designed Shahed drones have been known to weave, deke, and loiter through Ukrainian skies, distracting and frustrating air defense systems.

To deal with this aerial threat, Kyiv developed Pokrova, a secretive mesh network of EW systems that was revealed earlier this year.

“It’s not one, not two, not three transmitters” that make up Ukraine’s electromagnetic force field, Oleksandr Fedienko, a Ukrainian politician who serves as deputy chairman of a parliamentary committee on digital transformation, wrote on Telegram earlier this year. “There are hundreds of thousands of devices that are installed throughout the country.”

Pokrova isn’t just jamming the Shahed navigation systems, but spoofing their signal. This allows Ukrainian EW operators to feed them new coordinates, gently bringing down the drones so that they can be analyzed and cannibalized for parts. In recent months, Ukraine managed to spoof the signals being sent to these drones—flying more than 100 back into Russia.

Fedienko promised that Ukraine was still racing to scale up the system even further. “It's only a matter of time when the rockets and missiles with which the Russians attack us will fly in the opposite direction,” he wrote.

EW isn’t completely foolproof. But it remains an incredibly promising defensive technology when layered on top of other anti-air systems.

Ukraine’s ability to scale up this domestic industry has put it toe-to-toe with Russia, once thought to have the most impressive EW program in the world. But Russia has learned and adapted too. It’s now a “cat-and-mouse game,” Clark says.

Beating EW

In a secret drone workshop in Kyiv, Yvan holds up a tiny chip. Installed on a small FPV drone, Yvan hopes this chip could overcome Russia’s EW efforts.

With these chips and two cheap antennas, Yvan’s drones are programmed to hop across the electromagnetic spectrum at a dizzying rate, as many as 25 times per second, in unison with its base station.

Yvan hopes that the link between the drone and its operator can move frequencies faster than Russian EW operators can jam the signal. If that works, it could keep these drones in the air significantly longer. AI is already being used to make this signal-hopping seem as random as possible. (Just as AI is being used to detect the hopping pattern in order to predict its next move.)

There are existing solutions to these problems, like controlled reception pattern antennas (CRPAs), which can tune out jamming signals. However, they can cost upwards of $30,000 per unit, meaning Ukraine simply cannot afford to acquire them at scale. So they’ve had to innovate. Yvan’s solution can be dispatched for just hundreds of dollars.

Ukraine first started sending drones deep into Russia in early 2023—with a brazen attack on the Kremlin itself. Then, one small drone exploded spectacularly over the Moscow sky. Since then, Ukraine has stepped up its efforts. In early September, Kyiv launched its most expansive drone attack on Russia since the beginning of the war: An estimated 158 drones descended on targets across the country, setting fires at oil refineries, power plants, and pipelines. Although most were downed, likely through more traditional air defense systems, the attack shows the limitations of Russia’s own EW defenses.

With this constant competition on the electromagnetic spectrum, defense companies are getting creative about how their drones travel.

“In the Western world, GPS always works. Here, GPS never works,” says Stepan, a Ukrainian defense executive. (WIRED is using only his first name for security reasons.) That’s why he’s been developing drones to operate without GPS—or its Russian equivalent, GLONASS. Instead, he employs the drones’ onboard cameras to conduct thermal imaging of the ground below, employing “pure math” to confirm its trajectory by checking terrain, landmarks, and waypoints. This is not entirely new: The US Tomahawk missile, for example, has used terrain mapping for decades. What’s novel is how quickly and nimbly Ukraine has been able to distribute this technology to its nascent drone industry.

Since speaking to Stepan in Kyiv in March, this strategy of terrain mapping has become more common on the battlefield. Artificial intelligence has helped augment how drones understand the land below. They’ve also introduced other kinds of strategies, such as using cell phone towers as landmarks to guide their trajectory—much like the Luftwaffe pilots used radio beams to guide their flight towards British cities.

“The newer systems are using a combination of GPS, terrain mapping, and electronic signal intelligence to figure out where they are and to make themselves more precise,” Clark says.

Ukraine is already coming up with new ideas about what it could achieve if its drones can penetrate deeper into Russia. One drone prototype is equipped with EW systems that could, if it lands in the right spot, wreak havoc on Russian radar, air defense, and communications systems.

Innovation isn’t just moving forward—it’s also looking backwards. One of the most ingenious innovations being deployed in Ukraine is the German-made HIGHCAT drone, and it’s surprisingly old school. A lightweight quadcopter, the drone comes with a 6-mile cable, providing a fixed link to its base station.

It’s not just uncrewed aerial vehicles that are targeted by EW: Ukraine has increasingly deployed land and naval drones to aid in its fight to recapture territory.

Drone manufacturer SkyLab has, despite its name, become known for its ground-based autonomous vehicles. Those land vehicles have been used to deliver artillery, carry wounded soldiers, and could even be used for demining efforts. At their secretive offices in Kyiv, Denys gestures to a stout four-wheel vehicle in the corner. He says SkyLab has been exploring everything from AI to lidar to help these devices find their way home, even in an electromagnetic barrage. (WIRED is identifying the executive with a pseudonym for security purposes.)

“What frequency and mode do I have to use in the next version? What cameras, what gimbals, what logistics, what batteries?” he says. “Now it’s six, maybe seven generations of this rover.”

Innovate or Die

The Battle of the Beams was on track toward an electromagnetic stalemate. As they continued to improve and pioneer their radio warfare technique, neither the British nor the Germans looked set to gain a meaningful advantage over the other.

Then Britain innovated. When the Bristol Beaufighter took to the skies in mid-1940, it adapted Germany’s innovation to create an early aircraft interception radar. By using radio signals to identify enemy planes in the dark skies, British pilots quickly began downing Luftwaffe bombers and took back control of its airspace. The Germans then abandoned the Blitz and redeployed most of their offensive air assets eastward.

England’s victory in the battle came, in large part, because it was capable of uncovering the secrets to Germany’s innovation and reverse engineering it.

That’s happening in Ukraine, too, in both directions. Filimonov says his company’s effort to stay one step ahead is always frustrated by the “rats”—those who are “gathering information and then sending this information to our enemy.” The longer Ukraine’s technological innovation remains a secret, the more effective it will be. On the other side, Piranha-Tech’s Momot says he is always racing to identify Russia’s technological leaps forward, then “developing a countermeasure before the enemy can start large-scale production.”

Late last year, Valerii Zaluzhnyi, the erstwhile commander-in-chief of the Ukrainian Armed Forces, wrote in a detailed paper that Ukraine had achieved “parity” with Russia on EW—but it needed superiority.

While Ukraine is iterating advantages, a real breakthrough may have to come from Washington.

The United States has transferred an enormous amount of equipment to Kyiv, but it hasn’t—yet—handed over the EW crown jewels. “Electronic warfare is one of those very, very closely held technologies for the US and its closest partners,” Mick Ryan, a veteran of the Australian military and an independent military analyst, tells WIRED. “We're going to have to change the paradigm on how we look at EW and how we share the technologies with other partners, if we want to beat the Russians.”

Clark agrees that the Pentagon is “holding back some of the most sophisticated capabilities,” but there are signs that has changed in recent months: When the American-made F-16 fighter jets arrived in Ukraine in August, the US announced it had upgraded the jets with advanced onboard EW systems.

“One F-16 with a reprogrammed pod won’t achieve air dominance alone, but it may give you a pocket of air superiority for a moment’s time to achieve an objective that has strategic importance and impact,” the director of the US Air Force 350th Spectrum Warfare Wing said in a statement.

More than 80 years after the Battle of the Beams, Ukraine has put a modern spin on the Bristol Beaufighter: drone-on-drone combat. Footage emerged last year of two drones duking it out over the front lines. In mid-April, Ukrainian president Volodymyr Zelensky was briefed on a new drone capable of intercepting Russian helicopters and loitering munitions.

The world may soon see more of these drone dogfights. Igor, another defense executive (who WIRED is not identifying for security reasons) says his company has been working furiously on a drone designed to hunt and destroy Russian UAVs.

Igor’s anti-drone drone would be a “fire and forget” solution, he says, meaning the drone could loiter in the skies, using a suite of onboard sensors to target all incoming Russian drones. If perfected, it would bring the story of EW full-circle.

There’s one big technological problem with having these drones patrol the skies, Igor says. “You need to confirm that it’s not a bird,” he laughs. “You don’t want to make enemies with Mother Nature.”

Jurassic Jumble Reboot Recap

((I delayed on this long enough. Here's a general concept of how the plotline of "Jurassic Jumble" would go in the DT17 universe with my Honker, featuring my takes on the characters Stegmutt and Dr. Fossil as well as the reboot versions of Darkwing and Gosalyn/Quiverwing, who I will be writing out the parts of myself.))

There's been a rash of computer components stolen across multiple parts of Saint Canard, with witnesses from every crime scene claiming to have been distracted by the sight of a giant figure stomping around just out of sight in the shadows, slipping away just before anyone can get on the scene and get a good enough look at it to see what it is. Those distractions had apparently been enough for an unseen party to slip in and grab the goods and then hightail it by the time anyone was looking again.

Honker working with WANDA manages to build up a solid hypothesis of what the unknown burglar may be attempting to build with the stolen parts and where they may strike next. Team Darkwing have a stakeout to catch the criminal(s) in the act. When something causes a ruckus outside, DW and LP go to confront the source while the kids stay behind to guard the module predicted to be the target.

While the adults end up confronting what they get just a good enough look at to identify as seemingly a bipedal stegosaurus before it runs off and loses them, someone unseen knocks out the kids with sleeping gas and has already made off with the module piece by the time they wake up. Darkwing, however, had planted a tracer on the module just in case. Honker, back at base, runs a GPS scan for the tracer and is shocked that it pings underground at the coordinates of the St. Canard Natural History Museum.

The team infiltrates the museum after hours, eventually finding the secret passage to an underground base and split up for clues. Gos and Honk end up finding a collection of artifacts, including one in the forefront held in a clear biohazard-marked container: a glowing blue piece of rock. Gosalyn immediately recognizes it as the missing piece of the Stone of What Was, one of numerous artifacts from FOWL's Library of Alexandria base that SHUSH failed to locate during the post-battle raid.

The two are caught by a large, talking bipetal stegosaurus. But as soon as he starts talking--both due to the familiar voice and the stegosaurus seemingly recognizing Honker and becoming awkward at seeing him there under these circumstances--Honker realizes that the anthropomorphic dinosaur is the museum custodian Mutt, whom he'd met a few months back during a visit with an elf friend from Duckburg. Upon being identified, Mutt claims that he goes by Stegmutt now, vaguely gesturing to his current form as the reason why.

A pterodactyl in a snug-fitting lab coat and relatively small square glasses appears behind Stegmutt, harshly chastising him for not locking away the intruders on the spot. Stegmutt, crumbling to the other dinosaur's authority, very reluctantly pushes the kids into a holding cell (virtually identical to the ones FOWL used in the Library of Alexandria) and locks them in with an apologetic look. Honker also recognizes the pterodactyl, as he was once the elderly chicken scientist named Dr. Barnabas Klykos, who corrects him by saying the Klykos is no more and identifying himself in dramatic fashion as Doctor Fossil. Both he and Stegmutt had apparently come in contact with the Stone Fragment of What Was while holding a piece of fossil; the latter accidentally and the former on purpose after seeing the effects.

Dr. Fossil proceeds to go into a big rant about how the scientific community scoffed at his dream of bringing humanity back to its prehistoric roots, yet he had everything he could've needed to make his vision a reality except a form of genetic bonding agent (The Stone Fragment of What Was, which he recently acquired on the black market from a former FOWL Egghead) and the proper relay antenna to broadcast the signal far and wide (just built from all the stolen parts). Just as he's boasting there's no one to stop him at this stage of his plan, cue the purple smoke bomb and an "I am the terror..." speech.

While the adults confront Dr. Fossil, Honker sympathetically reaches out Stegmutt, who he recognizes deep down doesn't really want any part in this. Stegmutt, however, feels he has no say in the matter, as Dr. Fossil seems to have convinced him he'll have nothing left outside of servitude to him, especially considering what he's now become. Honker, with Gosalyn quickly joining in, try to encourage him to find a better life for himself with people who respect him and his feelings, something that surprises and touches Stegmutt.

Dr. Fossil, however, quickly barks at him to come handle Darkwing and Launchpad, and Stegmutt quickly folds to his authority again. As he leaves to do that, Stegmutt looks back at the kids and assures them that, while Dr. Fossil maybe has been acting nuttier than usual lately, nobody's gonna get hurt too badly from this; people are just gonna become cool new prehistoric versions of themselves. But he's clearly trying to convince himself in the moment just as much.

As Stegmutt reluctantly fights back against the Masked Mallard and the pilot, Dr. Fossil rushes to the next room where his relay antenna is completed and carefully slots the Stone Fragment of What Was into its place before powering up the machine. Once the antenna powers up and connects to a satellite network above, random people all over are hit by the effects and start devolving into prehistoric versions of themselves.

The kids have a good view of what's happening from the vantage point of their holding cell, and Honker starts talking to Fossil as he runs his equipment over concerns that dinosaurs and such wouldn't exactly fit in with the current era. The mad scientist laughs it off by claiming that the current era is about at an end anyway. Humans are already priming their planet for an extinction-level event as it is with their various environmental crimes as deforestation and greenhouse gasses; the meteor scheduled to pass by will finish the job once the hacked satellite network draws it in.

Honker's horrified at what he spells out is Dr. Fossil's attempt to artificially generate a mass extinction-level event that'll kill off anyone that doesn't get affected by the devolution ray. Someone else is also horrified, as it turns out the fight between the two older ducks and the stegosaurus got close enough that Stegmutt heard everything. Stegmutt calls his mentor out on using him for such a cruel and genocidal scheme, but Dr. Fossil insults him back by saying the young janitor was clearly too stupid to see it for himself and that he has no life for himself away from him. Fossil also claims that it's too late to stop him anyway.

Feeling hurt and betrayed, Stegmutt challenges that notion by stepping aside to let DW and LP tackle him and then turns to smash the controls of the kids' holding cell with his tail, freeing them. Honker has just enough time to rush to the controls of the relay antenna to have the satellite network repel the meteor it had just latched onto and then reverse the effects of the outgoing devolution rays. Dr. Fossil is taken down, and SHUSH is called in to clean up.

While Darkwing and SHUSH works to accommodate for Stegmutt's living conditions, as he's effectively homeless due to Dr. Klykos having provided his apartment space (which probably wouldn't be able to accommodate a stegosaurus man anyway), the agency's scientists determine that while those affected by the ray could be returned to normal, physical contact with any part of the Stone of What Was resulted in what was (for the foreseeable future, as they were still studying the artifact) an essentially permanent transformation.

Team Darkwing comfort Stegmutt, who's feeling lost and unsure of his future now. Uplifted by their assurance that they'll help him find a place for himself, Stegmutt decides he wants to use his new dinosaur form for the greater good and help those in need. By the end of this adventure, there's a new hero in St. Canard. Stegmutt gets his superhero origin story, and Dr. Fossil gets jailtime.

The Impact of Antenna Shape on Performance

Antennas are the hidden heroes of modern communication networks, supporting everything from wireless internet to satellite communications. While many elements affect antenna effectiveness, one of the most important but often underestimated is antenna design. The geometry of an antenna influences not only its efficiency and frequency range, but also its directionality, bandwidth, and gain. This article examines how antenna shape affects performance and why it matters in a variety of applications.

How Antenna Shape Impacts Performance An antenna's geometry determines numerous crucial performance characteristics, including:

Radiation Pattern The radiation pattern describes how an antenna transmits energy into space. For example:

Dipole antennas are typically linear in design and provide an omnidirectional radiation pattern, making them excellent for applications that require consistent coverage.

Parabolic Antennas: Shaped like a dish, these antennas direct energy into a narrow beam, making them ideal for long-distance communication and radar.

Gain and Directivity. Antenna gain quantifies how efficiently it radiates energy in a certain direction when compared to an isotropic source. The shape of the antenna has a direct impact on this:

Horn antennas: Their flared design concentrates radiation in a single direction, increasing gain.

Understanding ADS-B LNA: Enhancing Aircraft Surveillance with Low Noise Amplifiers for Better Signal Clarity

Aircraft surveillance has undergone significant technological advancements over the years, with Automatic Dependent Surveillance-Broadcast (ADS-B) being one of the most notable. ADS-B allows aircraft to broadcast their position, velocity, and other critical data to ground stations and other aircraft. This system has revolutionized air traffic management by providing more accurate and real-time information compared to traditional radar systems. However, for ADS-B systems to function optimally, they require specific components, one of which is the Low Noise Amplifier (LNA). Understanding the role of ADS-B LNA is crucial for those interested in aviation technology.

What is ADS-B?

Before diving into the details of ADS-B LNA, it’s essential to understand what ADS-B is and how it works. ADS-B is a surveillance technology that relies on aircraft broadcasting their GPS-derived position and other data to ground stations and other aircraft. This system improves the safety and efficiency of air traffic control by providing precise and real-time information. Unlike traditional radar, which requires ground stations to actively track aircraft, ADS-B allows aircraft to passively share their position, reducing the reliance on radar and enhancing coverage, especially in remote areas, antenna preamplifier.

The Importance of ADS-B LNA

One of the critical components of an ADS-B system is the Low Noise Amplifier (LNA). The LNA is a device that amplifies weak signals received by the ADS-B receiver while minimizing the amount of noise added to the signal. In simple terms, it ensures that the ADS-B receiver can pick up signals from aircraft that are far away or have weak transmissions without being drowned out by background noise.

The primary function of the ADS-B LNA is to boost the incoming signal strength without significantly increasing the noise level. This is crucial because ADS-B signals, transmitted on the 1090 MHz frequency, can be quite weak, especially over long distances. Without an LNA, these weak signals might be lost or degraded to the point where they are no longer useful for surveillance purposes.

How ADS-B LNA Enhances Performance

The inclusion of an LNA in an ADS-B system has several benefits:

Extended Range: By amplifying weak signals, an LNA allows ADS-B receivers to detect aircraft at greater distances, improving coverage and situational awareness, especially in areas where ground-based radar coverage is limited.

Improved Signal Clarity: The LNA enhances the signal-to-noise ratio, which means the ADS-B receiver can distinguish between the actual aircraft signal and background noise. This results in clearer and more accurate data for air traffic controllers.

Better Performance in Challenging Environments: In environments with significant interference or obstacles, an ADS-B LNA can help mitigate these challenges by boosting the desired signal above the noise level.

Cost-Effective Solution: Implementing an LNA in an ADS-B system is a cost-effective way to enhance performance without the need for more complex and expensive solutions.

Choosing the Right ADS-B LNA

When selecting an ADS-B LNA, several factors should be considered, such as gain, noise figure, and power consumption. The gain of the LNA determines how much the signal is amplified, while the noise figure indicates how much noise the LNA introduces to the signal. Ideally, a high-gain, low-noise figure LNA is preferred for ADS-B applications. Additionally, the LNA should be energy efficient to minimize power consumption, especially in installations where power is limited.

Conclusion

ADS-B LNA plays a critical role in enhancing the performance of ADS-B systems by amplifying weak signals and reducing noise. This allows for improved aircraft detection, better coverage, and enhanced air traffic management. As ADS-B continues to be a key technology in modern aviation, the importance of choosing the right LNA cannot be overstated. Whether for commercial aviation or hobbyist applications, understanding the benefits and selection criteria of ADS-B LNA is essential for optimizing aircraft surveillance systems.

Excerpt from this New York Times story:

There’s a lot of ocean out there, and boats engaging in illegal fishing or human trafficking have good reason to hide.

But even the stealthiest vessels — the ones that turn off their transponders — aren’t completely invisible: Albatrosses, outfitted with radar detectors, can spot them, new research has shown. And a lot of ships may be trying to disappear. Roughly a third of vessels in the Southern Indian Ocean were not broadcasting their whereabouts, the bird patrol revealed.

Albatrosses are ideal sentinels of the open ocean, said Henri Weimerskirch, a marine ecologist at a French National Center for Scientific Research in Chizé, France, and the lead author of the new study published on Monday in Proceedings of the National Academy of Sciences. “They are large birds, they travel over huge distances and they are very attracted by fishing vessels.”

Dr. Weimerskirch and his colleagues visited albatross breeding colonies on the Amsterdam, Crozet and Kerguelen Islands, French outposts in the Southern Indian Ocean. The team attached roughly two-ounce data loggers to 169 adult and juvenile birds. The equipment consisted of a GPS antenna, a radar detector and an antenna for transmitting data to a constellation of satellites.

From November 2018 through May 2019, the researchers watched as breeding adults foraged at sea for 10 to 15 days at a time, flying thousands of miles per trip, and as juveniles left the colony. The birds traversed a total area of roughly 18 million square miles, about five times the size of the United States, always on the lookout for radar signals.

Fishing boats are regularly in those waters, seeking tuna and Patagonian toothfish — otherwise known as Chilean sea bass — that frequent areas near the islands.

The feathery dragnet recorded radar blips from 353 vessels, which used radar to navigate and detect other boats. But only 253 of the boats had their Automatic Identification System transponder turned on, which broadcasts a ship’s identity, position, course, speed and other information, as required by International Maritime Organization regulations. One hundred ships, or 28 percent, were silent.

They might have been fishing without a license or transferring illegal catches onto cargo vessels, Dr. Weimerskirch said. “A lot of fishing boats prefer not to be located.”
