A Long March-3B/YZ-1 has orbited a new pair of navigation satellites in what was China’s ninth launch of the year. The launch of Beidou-3MEO5 (or Beidou-30) and Beidou-3MEO6 (or Beidou-31) took place at 17:56 UTC from the LC2 Launch Complex of the Xichang Satellite Launch Center, Sichuan province. It will take over four hours to complete the mission. The MEO satellites are the Medium Earth Orbit component of the third phase of the Chinese Beidou (Compass) satellite navigation system. The satellites are part of a fleet that will expand the system to a global navigation coverage.

The satellites are using a new bus that features a phased array antenna for navigation signals and a laser retroreflector, with a launch mass 1,014 kg. Spacecraft dimensions are noted to be 2.25 by 1.0 by 1.22 meters. Usually, the satellites reside in a 21,500 – 21,400 km nominal orbit at 55.5 degrees.

The Beidou Phase III system includes the migration of its civil Beidou 1 or B1 signal from 1561.098 MHz to a frequency centered at 1575.42 MHz – the same as the GPS L1 and Galileo E1 civil signals – and its transformation from a quadrature phase shift keying (QPSK) modulation to a multiplexed binary offset carrier (MBOC) modulation similar to the future GPS L1C and Galileo’s E1.

Kiinalainen kantoraketti putoaa taivaalta ja osuu rakennukseen

Kiinalainen kantoraketti putoaa taivaalta ja osuu rakennukseen

Helmikuun 12. päivänä 2018 näimme vuoden seitsemännen satelliittilaukaisun. Long March-3B/YZ-1 -raketti vie mukanaan parin navigaatiosatelliitteja. Laukaisu tapahtui hieman jälkeen kello 05:00 (UTC) LC2-laukaisualustalta Xichang -satelliittilaukaisukeskuksesta, Sichuan-provinssissa. Tehtävän selvittämiseen meni yli neljä tuntia.

  Kun amerikkalaiset raketit tippuvat mereen, Kiina jatkaa niiden pudottelua maihin.

Vaikka he yrittävätkin laskea nämä pudotusalueet erittäin huolellisesti välttääkseen asuttuja alueita, joillain alueilla he evakuoivat kokonaisen kaupungin. Joskus nämä kantoraketit osuvat lähelle asuttuja alueita.

Nyt kantoraketti osui Tianlin-maakuntaan, Guangxiin jossa raketinpalaset osuivat erääseen rakennukseen.

Rakennus evakuoitiin etukäteen, mutta kantorakettien tiputtelu asuinalueille tuntuu joka tapauksessa hullulta.

Long March 3B launch BeiDou-3 MEO-3 & MEO-4

China sent two satellites into orbit on a single carrier rocket for its domestic BeiDou Navigation Satellite System (BDS) on Monday. The launch took place at 05:03 UTC from the LC2 Launch Complex of the Xichang Satellite Launch Center, Sichuan province. It took over four hours to complete the mission. The twin satellites, which form a network with four previously launched BeiDou-3 satellites, were the fifth and sixth satellites in the BeiDou-3 family. They entered orbit more than three hours after the launch from the Xichang Satellite Launch Center in southwest China's Sichuan Province.

China Launches Two Beidou-3 Navigation Satellites

The twin satellites were launched by the LM-3B YZ-1 rocket. The launch was the 267th mission for the Long March rocket family. The MEO satellites are the Medium Earth Orbit component of the third phase of the Chinese Beidou (Compass) satellite navigation system. The satellites are part of a fleet that will expand the system to a global navigation coverage.

CASC launches latest Beidou-3M satellite duo

A new pair of navigation satellites were successfully launched by China on Thursday, using a Long March-3B/YZ-1. The launch of the Beidou-3M pair took place at around 23:18 UTC from the LC2 Launch Complex of the Xichang Satellite Launch Center, Sichuan province. It took over four hours to complete the mission. The launch was previously scheduled for 2017. However, this was delayed due to a partial launch failure with a previous launch of this rocket during the Zhongxing-9A (ChinaSat-9A) mission, which resulted in the satellite being lofted to a lower than planned orbit.

China Sends Twin Beidou-3 Navigation Satellites into Space

It is expected that the Beidou-3MEO3 (Beidou-26) and Beidou-3MEO4 (Beidou-27) satellites will be onboard, but a TV news report following last November’s BDS launch – featuring the satellite production facility in Shanghai – referred that the two satellites about to be shipped were marked as “M7 & M8”. So, we will have to wait what designation is given to the satellites when in orbit. The MEO satellites are the Medium Earth Orbit component of the 3rd phase of the Chinese Beidou (Compass) satellite navigation system. The satellites are part of a fleet that will expand the system to a global navigation coverage. The satellites are using a new bus that features a phased array antenna for navigation signals and a laser retroreflector, with a launch mass 1,014 kg. Spacecraft dimensions are noted to be 2.25 by 1.0 by 1.22 meters. Usually, the satellites reside in a 21,500 – 21,400 km nominal orbit at 55.5 degrees.

The Phase II B1 open service signal uses QPSK modulation with 4.092 megahertz bandwidth centered at 1561.098 MHz. The current Beidou constellation spacecraft are transmitting open and authorized signals at B2 (1207.14 MHz) and an authorized service at B3 (1268.52 MHz).

China's Long March 3B/G2 Rocket Launches Beidou-3 G1Q satellite into GTO

China successfully lofted a Beidou navigation satellite into a geosynchronous transfer orbit Thursday with an enhanced #LongMarch-3B launch from the Xichang Satellite Launch Centre.

Liftoff took place at 15:57 universal time (23:57 local, 11:57 Eastern) with the China Aerospace Science and Technology Group (CASC) declaring mission success just over an hour after launch.

The launch was the 32nd Chinese orbital launch of 2018 and the 30th carried out by state-owned space programme contractor CASC, while the Beidou-3 G1Q Satellite is the 41st launched in the series, with the first launched in 2000.

The satellite's main functions are providing positioning, navigation and timing services as part of the 35-satellite Beidou network, which China is pushing to complete in the first half of 2020.

Unlike most Beidou satellites, which operate in medium Earth orbit at around an altitude of 21,000 kilometres, the third phase Beidou-3G1Q satellite will occupy a slot in geostationary orbit 36,000 km above the Earth, facilitating backward compatibility with earlier phase series satellites.

The satellite is based on the 4,600 kg DFH-3B bus designed for geostationary orbit with a phased array antenna for navigation signals and a laser retroreflector.

In addition to navigation services, the satellite carries a satellite-based augmentation system (SBAS) and an improved radio determination satellite service to provide short message services.

The Long March 3B is expected to be in use again around mid-November before launching the Chang'e-4 lunar far side lander and rover mission in early December.

China's answer to GPS

The Beidou navigation system, which takes its name from the Chinese asterism equivalent to the Plough or Big Dipper, is China's answer to the US Global Positioning System (GPS), Russia's GLONASS and Europe's Galileo global navigation satellite system (GNSS) constellations.

The completed system of 35 operational Beidou satellites will have 27 satellites in MEO at around 22,000 km altitude, five in geostationary orbit and three more in inclined geosynchronous orbits at 35,786 km, providing global GNSS coverage with a positioning accuracy of 2.5 metres.

Systems like GPS and Beidou provide civilian applications such as navigation for shipping and road traffic, mapping and surveying and are used wide range of sectors. They also assist military forces from space, facilitating targeting, positioning and locating, and the synchronising of operations. The development of Beidou will end previous Chinese military reliance on GPS.

Beidou, also referred to as BDS, is considered a project of national significance and part of the country's national security, economic and social development.
