摘要
中国新一代静止气象卫星—风云四号(FY-4),包括光学和微波探测两种类型的卫星,将呈现多颗卫星同时在轨的状态.测距、轨道确定和预报(称为测定轨)是卫星图像导航、姿态机动和轨道管理的支撑系统,具有高精度和快速响应的特点.针对地面测距定轨系统在发展中表现出来的问题和局限性,以及静止气象卫星采用全球导航卫星系统(GNSS)测定轨的精度和时效性问题,进行了仿真,获得了北斗导航系统(BDS)、全球定位系统(GPS)和它们组合的连续可同时接收的卫星数量、定位精度等参数.分析表明,GNSS测定轨满足新一代静止气象卫星发展要求.
The new generation of China geostationary meteorological satellites,FY-4,includes optical and microwave sounding satellites,will present the status of multiple satellites in orbit at the same time.Ranging,orbit determination and prediction(called orbit determination)are the supporting systems of satellite image navigation,attitude maneuver and orbit management,which are characterized by high accuracy and fast response.In view of the problems and limitations of the ground orbit determination system under development,as well as the accuracy and timeliness of the geostationary meteorological satellite orbit determination using GNSS(global navigation satellite system),simulations are carried out,and the parameters such as the number of satellites that BDS(BeiDou navigation system),GPS(global position system)and their combination can continuously receive simultaneously,and positioning accuracy are obtained.The analysis shows that the GNSS orbit determination meets the development requirements of the new generation of geostationary meteorological satellites.
