Research on Application of Satellite Common-View Technology in the Test of Synchronous Communication Equipment

By analyzing the high-precision time-frequency synchronization demand of communication system and the characteristics and applicability of existing testing methods, satellite common-view equipment is selected as the testing reference, and the actual testing of frequency and time performance of communication network equipment is carried out to realize the application of satellite common-viewi technology in the testing of communication synchronization equipment. The test results show that the satellite common-view technology can better meet the testing requirements of the current communication synchronous network. Satellite common-viewing technology is studied and its application in the test of communication synchronous equipment is realised in this paper. Firstly, the high precision time-frequency synchronization requirements of the communication system and the characteristics and applicability of the existing test methods are analyzed. Secondly, equipment based satellite co-viewing technology is selected as the time-frequency reference to test the time-frequency performance of the actual communication network equipment. The test results show that satellite co-viewing technology can meet the test requirements of communication synchronous network well.
