At 9:43AM on June 23, the 55th BDS satellite, the last BDS-3 satellite, was successfully launched on board a Long March-3B rocket at the Xichang Satellite Launch Center. It marked that the full completion of the BDS constellation deployment was accomplished a half year ahead of schedule.

The launched satellite, a geostationary satellite, will undergo a series of on-orbit tests before it is officially commissioned. Comprehensive tests for the entire BDS system will be conducted to ensure stable and reliable operation of the system with outstanding performances. Upon the completion of the tests, BDS will possess full operation capability to provide all-time, all-weather and high-precision positioning, navigation and timing services to global users as well as the services of satellite-based augmentation, short message communication, precise point positioning and other characteristic services for the selected regions.
