摘要
开展了基于Gooding算法的400km天基平台光学目标监测的轨道确定研究,当测量误差为3"和6"时,分别对800,1500及36000km轨道高度目标进行初始轨道确定及轨道改进分析.仿真结果表明,利用400km轨道高度平台对800~1500km轨道高度目标进行初定轨,测量数据误差为3"~6"时,4~15min弧段的初定轨精度约在10km量级,1~2min弧段的初定轨精度约在100km量级;15min初定轨弧段轨道改进后误差在100m量级,弧段小于10min时轨道改进误差精度在km量级.利用400km轨道高度平台对36000km轨道高度目标进行初定轨,测量数据误差为3"时,15~20min弧段的初定轨精度约在数十km量级,8~10min弧段的初定轨精度在100km量级;轨道改进后误差在km量级.测量数据误差为6"时,20min弧段初定轨精度在10km量级,8~15min弧段初定轨精度在100km量级,轨道改进后误差精度在10km量级.
In this paper,optical target monitoring orbit determination using the Gooding algorithm based on the 400km altitude space platform was researched.The measurement error was set to 3"and 6"respectively for 800km,1500km altitude low Earth orbits and 36000km altitude geosynchronous orbit to determine the initial orbit and precise orbit.Simulation results show that the initial orbit determination accuracy of the 4~15min arc is about 10km,and the 1~2min arc is about 100km when the measurement data error is between 3"and 6".The error of 15min initial determination arc is 100m.As the arc is less than 10min,the improved error accuracy of the orbit is in the order of km scale.As the measurement data error is 3",the initial orbit determination accuracy of the 15~20min arc is about tens of kilometers,and that of the 8~10min arc is 100km.The improved orbit has an error of km.When the measurement data error is 6",the accuracy of the initial orbit determination of the 20min arc is at the magnitude of 10km,the accuracy of the initial orbit determination of the 8~15min arc is at the magnitude of 100km,and the error accuracy of the improved orbit is at the magnitude of 10km.
