摘    要:本文简要分析了当前采用的各种时刻比对方法和技术,强调指出了静止卫星共视法在当前我国时刻比对工作中的实际应用价值,并对亚星一号进行了动力学定轨及时刻比对实验.实算结果表明:在现有的观测精度下,对亚星一号进行微分轨道改进后,可使共视法比对的事后处理精度优于1μs,其预报精度在1—2天内可达1μs,在一个星期内也只有几个微秒.

关 键 词:亚星一号,定轨,时刻比对

Abstract:In this paper, many kinds of methods of time comparison which are adopted atpresent are summarized and analysed briefly. The applied value of common viewmethod by means of synchronous satellite is pointed out emphatically. The method istested by Asia-satellite No. 1. The results using orbit improvement show that thepost-processing error of time comparison is less than 1 us. The prediction error isabout 1 u in 1-2 days and several microseconds in one week according to theobservational precision attained at present.
Keywords:Synchronous satellite   Orbit determination   Time comparison
