Signals from space

Whether you’re scrambling up Mount Everest or trekking the Sahara Desert, you’re never more than a few seconds from your friends. That’s because telephones and the internet, linked by space satellites, can zap messages from any place on Earth to anywhere else at the speed of light.

Earth might seem huge but no two places are more than half its circumference apart- and a beam of light can cover that distance in less than a tenth of a second. When you chat to friends in faraway countries by phone or online, the sound of your voice the image of your face on your webcam, or the message you type is bounced across Earth in less than a second via satellites in space. Signals from space satellites can also tell us exactly where we are. Thanks to technology like GPS (Global Positioning System), getting lost has now become almost impossible.

Assisted GPS

A mobile phone can locate roughly where it is by its connection to the nearest transmitter mast. Assisted GPS uses Wi-Fi and GPS signals to precisely locate a mobile  phone’s so it can tell you exactly where you are.

When signals are blocked by trees or large buildings Assisted GPS is used to help to determine a location

Wi-Fi

Radio-Wave signals from Wi-Fi internet hotspots help mobile phones pinpoint their location.

Mobile Phones

These send and receive calls at the speed of light using microwaves (very small radio waves).

Mobile Phone masts

Mounted on high buildings mast relay calls from mobile phones to the landline phone network

Satellite navigation

A car’s “sat-nav” uses a stored database of maps linked to GPS receiver detects your changing position. A computer in the sat-nav calculates how fast you are moving and continually redraws the map to show your progress.

Satellite

GPS Satellites catch signals from Earth and send new signals straight back large solar panel on it generates electric power from the sun

GPS Signals

No signal satellite could cover every place on Earth at once. That’s why the GPS systems has a network of at least 24 seprate spacecrafts. No matter wherever you are, at least four of them are sending signals to your phones.

Finding your positions

It takes less than a second for a GPS signal to reach Earth from space. Travelling at a speed of light. Knowing how long the signal took, a GPS reciever calculates the how far is the satellite is. Using signals from at least three satellites, it is possible to calculate your precise location.

#TBT to two months ago, the last Astronomy on Tap event at the Way Station in Brooklyn. Astronomer Dr. Louise Edwards wore space pants (purchased at hmstreetstyle) and a t-shirt repping Black Girls Code to talk about the Planck Mission and its studies of the early Universe.

Louise is a knowledgeable, inspirational, & fun presenter, and she might be the only astronomer I know who was on a stamp - so cool!
