| 摘 要： | 分析了轨道预测跟踪(OPT)与传统步进跟踪模式的跟踪方法及原理.在某限动站的实际测试应用表明,OPT模式能够改善测角数据的有效性,对机械结构的磨损也比较小,同时对于超过10°的大倾角卫星也能够满足跟踪精度要求.系统的指向精度提高了一倍,跟踪精度从0.0318°提高到了0.023°.分析结果表明,相对于传统步进跟踪模式,OPT模式具有明显优势.

| Abstract: | The tracking method and theory of Orbit Prediction Track (OPT) and step tracking
mode is analyzed.Practical application and tests of a Li
mited Motion Antenna (LMA) illustrate that OPT mode can increase the validity
of angle measurin
g data, decrease the wear and tear on the mechanical structure. At the same time
, the accuracy can also meet the requirements for more than 10 degrees inclined
satellite. The pointing accuracy of using OPT mode doubles that of using step tr
acki
ng mode, and the tracking accuracy is improved from 0.0318 to 0.023 degrees. The
analysis results show that OPT mode has obvious advantages compared with the tr
aditional step tracking mode. |
