As a mature, fully functional and high-performance global satellite navigation system, the BDS currently has 50 operational satellites in orbit. It offers a global positioning accuracy of better than 10 meters, velocity measurement accuracy better than 0.2 meters per second, and timing accuracy within 20 nanoseconds.
Through its Precise Point Positioning (PPP) service signal, it can realize horizontal positioning accuracy better than 0.3 meters and vertical accuracy better than 0.6 meters.
According to earlier reports, the upgrade saw adjustments made to optimize the operational status of certain satellites.
