Summary
The China Satellite Navigation System Management Office announced July 31 that BeiDou has completed a full on-orbit upgrade of its existing constellation, with the stated goal of building a 综合时空体系 (comprehensive space-time system) by 2035. The upgrade documents a transition from constellation completion to capability deepening — integrating positioning, navigation, and timing into a broader architecture that extends beyond GPS-comparable PNT toward resilient, multi-domain space-time infrastructure. What specific satellites were upgraded, what new signal or accuracy parameters result, and what the 2035 architecture entails technically remain unspecified in this release.
