Time Delay Calibration Method for User Terminal of The BeiDou Navigation Satellite System
摘要
Abstract
T he accuracy of time delay calibration for the user terminal of the BeiDou nav‐igation satellite system has a great impact on the timing accuracy of the user terminal .So the time delay calibration must be carried out before timing accuracy test .In this paper ,two kinds of time delay calibration schemes for satellite navigation users with absolute delay and relative delay are studied .For the BeiDou user terminal without one pulse per‐second(1PPS) input interface ,two absolute time delay calibration methods are proposed .Experimental re‐sults show that the error of these two calibration methods is better than 2 ns ,which meets the requirements of the 5 ns index for the time delay calibration of the BeiDou user terminal .关键词
