| Abstract: | Since GPS has been an effective and convenient means to transfer precise time,clock synchronization technique based on GPS is more popular and important than ever before in many auto-control fields with computers.The theory of clock synchronization between GPS and high-precision clock built in computers was introduced in this paper,then first-order and second-order mathematical model of clock synchronization were given.The analysis results of the tests with real raw data showed that first-order model has ad... |
