BeiDou-3 M19, 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 combined rubidium and hydrogen maser atomic clocks giving BeiDou-3 timing precision genuinely competitive with the best GPS and Galileo satellites offer, a technical milestone that took Chinese engineers years of dedicated clock development to reach.
