BeiDou-3 M21, part of China's global navigation constellation completed in 2020 — the culmination of a program China built after a 1990s missile test near Taiwan reportedly lost GPS guidance, convincing Chinese military planners never to depend on a foreign-controlled satellite system again. This satellite contributes inter-satellite laser and radio crosslinks letting the constellation operate accurately even during extended gaps in contact with Chinese ground stations, a capability neither GPS nor GLONASS satellites of comparable generation carry.
