China has launched a new navigation satellite on Thursday, marking its 32nd orbital launch this year. The launch of Beidou-3G1Q (Beidou-1) took place from the LC2 Launch Complex of the Xichang Satellite Launch Center, Sichuan province, using a Long March-3B/G2 (Chang Zheng-3B/G2) launch vehicle. Launch time was 15:58 UTC.
The Beidou-3G satellites are the Geosynchronous Earth Orbit component of the third phase of the Chinese Beidou (Compass) satellite navigation system. The satellite is part of a fleet that will expand the system to a global navigation coverage.
The satellite is based on the DFH-3B bus that features a phased array antenna for navigation signals and a laser retroreflector, and also is equipped with an apogee propulsion system for final orbit insertion. The satellite has a launch mass of about 4,600 kg.
One new pair of Beidou-3M satellites is scheduled to launch before years end. Beidou-3M17 and Beidou-3M18 will be launched in mid-November.
The Beidou Navigation Satellite System (BDS) has been independently constructed, developed and operated by China taking into account the needs of the country’s national security, economic and social development. As a space infrastructure of national significance, BDS provides all-time, all-weather and high-accuracy positioning, navigation and timing services to ...
