Chinese President, Xi Jinping, officially commissioned the system on 31 July at a ceremony at the Great Hall of the People in Beijing.
The 55th and final satellite in the BeiDou constellation, launched on 23 June into geosynchronous equatorial orbit (GEO) at ~22,000 miles (~36,000 km), had completed all tests and been declared operational.
Hence the 3rd-generation BeiDou system (BDS-3), which began providing navigation services in 2018, has become operational worldwide. The final constellation comprises 27 medium earth orbit (MEO), 5 GEO and 3 inclined geosynchronous orbit (IGSO) satellites.
This should provide global navigation services similar to GPS, GLONASS and Galileo. It will use, amongst other transmissions, a frequency of 1575.42 MHz - the same as GPS L1 and Galileo E1 civil signals - and multiplexed binary offset carrier (MBOC) modulation, similar to the future GPS L1C and Galileo’s E1. Satellite-based augmentation (SBAS) and SAR facilities are included.
