It was learned from the China Satellite Navigation System Management Office that at 23:57 on the morning of November 1, Beijing time, China successfully launched the 41st Beidou navigation satellite with the Long March 3B carrier rocket at the Xichang Satellite Launch Center. This satellite belongs to the geostationary orbit satellite. It is the 17th global network satellite of China's Beidou 3 system and the first geostationary orbit satellite of the Beidou 3 system.
In addition to providing basic navigation services (RNSS), the satellite will also offer Short Message Service (RDSS) and Star Based Enhanced Service (SBAS). Among them, the short message service is fully compatible with the Beidou II short message service, the capacity is increased by 10 times, the user machine transmission power is reduced by 10 times, and the capability is greatly improved. Satellite-based enhanced services provide navigation services with higher precision and higher integrity in accordance with international civil aviation standards.
Subsequently, the satellite will be tested and tested on the scheduled orbit, and will be networked with the 16 Beidou-3 navigation satellites previously launched to provide timely services. According to the plan, before the end of this year, the Beidou system will also launch two medium-Earth orbit satellites.
The successfully launched Beidou navigation satellite and supporting carrier rocket were jointly developed by China Aerospace Science and Technology Research Institute and China Academy of Launch Vehicle Technology, respectively. This is the 290th space flight of China Long March series carrier rocket. flight.
