摘要
Abstract
The time comparison with by meansof synchronous satellite is a common method, which has the advantages of low cost, simpleoperation and wide scope of service. The key technique for raising theprecision of time comparison with the method is to determine and predictthe orbit of synchronous satellite more accurately. Based on theimprovement of the previous program for orbit determination andprediction, further in vestigations concerning time comparison usingthismethod is conducted in this paper. The experimental results show thatthe post-processing precision of time comparison obtained with the newprogram is about the same as that obtained with the previous program,which is better than 1 , but the pre-processing precision hasbeen raised greatly as compared to that obtained previously. With thenew program of orbit determination and prediction, the pre-processingprecision of time comparison can keep better than 1 in one week.关键词
