Abstract在卫星测地研究和航天实时飞行任务中都需要精密定轨计算,而精密定轨或轨道预报中都离不开定轨理论模型和模型参数的选取。工程技术人员如何根据任务要求的定轨精度来选择相应的定轨模型对完成工程任务至关重要。定轨计算给出的一般是理论模型和观测资料的内符合精度,定轨精度需要更高的外符合标准来检验。本文介绍了时间、坐标系统及其高精度的转换方法,并从应用的角度对国际天文学联合会(IAU)最新采用的定轨模型和精密定轨过程进行阐述;根据上述模型编写了精密定轨及激光资料预处理软件,给出了在初始根数误差较大情况下,使定轨计算快速收敛的重置参数的轨道改进算法;并通过全球激光测距网的测量资料进行精密定轨计算,以改进后的定轨残差均方根小于3厘米的激光卫星轨道作为外符合参考轨道,对工程上常用解析轨道预报模型SGP4/SDP4进行了检验,给出了该模型的预报误差放大规律和双行根数(TLE)的初始根数精度,以供工程技术人员参考。
Other AbstractBoth satellite geodesy and real-time space missions require precise orbit calculation, and the precise orbit determination can not be separated from dynamical model and model parameter. It is important that Engineers how to select the appropriate models based on the task. This article describes the time system coordinate system and high precision conversion method, and from the application point tells the recent IAU' dynamical models and the ocess of precise orbit determination. According to the model,we compile the precise orbit determination software and give an improved method of precise orbit determination by resetting model parameters. Taking the precise orbit of laser satellite by International Laser Ranging Service ranging data as a reference orbit, we test the commonly used analytical orbit prediction models SGP4/SDP4, we give the reliability of the model and initial accuracy of TLE for engineering and technical officers.
