Abstract
Post event time comparison technique based on GNSS is the key to time synchronization and time service. And it is also an important measure to correct the time difference of GNSS receiver and to improve its design and performance. The traditional post - time comparison is usually based on the Kalman filtering algorithm. This paper focuses on the algorithm of GNSS common-view time alignment based on Kalman filtering and RTS smoothing afterwards. In this paper we use CETC54 self-developed satellite navigation receiver to test the accuracy of combined common-view time comparison algorithm of GNSS navigation system based on Kalman filtering and RTS filtering. The test results show that the accuracy of common view time matching algorithm with RTS smoothing algorithm is better than the accuracy of a conventional common-view time comparison algorithm based on Kalman filtering.
