[HIGHLIGHTS] How does the Shenzhou 15 spacecraft escort the "Dream Realization Crew" flying triumph?

On June 6, the Shenzhou 4 manned spacecraft return module carrying the "Dream Crew" successfully landed at the Dongfeng landing site. The Shenzhou 10 mission is the 1000th flight of Chinese, and in this manned return mission, the updated guidance, navigation and control system (GNC system) and more than <> square meters of parachute escort spacecraft landed accurately and smoothly.

China's spacecraft return re-entry GNC technology has gone through two generations. The first generation is called the "standard ballistic adaptive guidance method" and is applied on 11 spacecraft. The four Shenzhou spacecraft in the batch of Shenzhou XII to Shenzhou XV use the "adaptive predictive guidance method".
