【摘要】：主要考察了CEI对静止轨道共位卫星的轨道确定能力。仿真结果表明,利用CEI对共位卫星进行定轨时,需采用基线阵列。对于110°E共位卫星采用三亚-昆明基线阵列、10 km基线和2 d的数据,可使绝对轨道精度达百米级;外推至14 d时,相对轨道精度保持在m级。同样,要使绝对和相对轨道精度达到相同的量级,对于80°E共位卫星,需选用昆明-三亚基线阵列、100 km基线和1 d的观测弧段;对于140°E共位卫星,需选用上海-三亚基线阵列5、0 km基线和2 d的观测弧段。
[Abstract]:The orbit determination capability of CEI for geostationary satellite is investigated.The simulation results show that the baseline array is needed to determine the orbit of the common satellite using CEI.For 110 掳E co-geostationary satellite, the data of 10 km baseline and 2 days from Sanya Kunming baseline array can make the absolute orbit accuracy reach 100 meters, and the relative orbit accuracy is kept at m level when extrapolated to 14 days.Similarly, in order to achieve the same absolute and relative orbital accuracy, for 80 掳E co-satellites, the Kunming Sanya baseline array with a 100km baseline and a 1 day observation arc should be selected, and for 140 掳E co-satellites,The Shanghai-Sanya baseline array should be selected at the base line of 50 km and 2 days of observation arc.
