本文给出了一种提高卫星跟踪精度的方法,并从理论上和实验上对下述两部分进行了讨论,跟踪系统误差的修正和卫星轨道预测的修正。在第一部分中,其结论是;跟踪系统的瞄准误差可用从星球观测来的数据精确地确定,因此修正能够具有约为0.001°的精度,在第二部分中,表明可以从单轨道的光学观测中推断出卫星轨道参数的视误差,而且在使用几个连续轨道高精度的修正之后,人们可以跟踪卫星。当给定轨道预测精度近似为1°时,对1000km高空的卫星,测量精度为0.1～0.2毫弧度或更精确些。
In this paper, a method to improve the satellite tracking accuracy is presented. The following two parts are discussed theoretically and experimentally, and the correction of the tracking system error and the correction of the satellite orbit prediction are given. In the first part, it is concluded that the tracking error of the aiming system can be accurately determined from the data observed from the planet, so that the correction can have an accuracy of about 0.001 °, and in the second part, it can be observed from a single-track optical observation Inferred satellite orbital parameters of the visual error, and in the use of several continuous orbit correction of high accuracy, one can follow the satellite. When the accuracy of a given orbit prediction is approximately 1 °, the measurement accuracy is 0.1-0.2 milliradians or more accurate for satellites at a altitude of 1000 km.
