| Abstract: | The time synchronization between a satellite and an earth station is the most importance of satellite navigation,and its precision and reliability have great influence on the precision and performance of navigation and orientation.The theory and measurement of both one-way time transfer,common-view time transfer and two-way time transfer navigation satellite timing is studied.The influence of the error sources on the timing accuracy is analyzed.Finally,the application of these methods is introduced. |
