摘要: During the eclipse seasons, BeiDou IGSO/MEO satellites perform attitude maneuvers from yaw-steering to yaw-fixed, while nominal yaw-angle is fixed zero. Unfortunately, different levels of orbit accuracy degradations in Precise Orbit Determination (POD) process occur this period. In paper, a reduce-dynamic orbital model with additional pseudo-stochastic parameters introduced improve quality. The geometrical corrections observations and force variations related are modeled investigated. modeling techniques applied for absorbing effects mis-modeled part maneuvers. POD results indicate significantly improved performance appropriate during seasons.
