| () |
| Abstract: |
| The importance of high precision timing is described, and the theory and measurement of both one- way and two -way navigation satellite timing is studied. The influence of the error sources on the timing accuracy is analyzed. Finally, the precision of two - way timing is evaluated, and helpful conclusion is drawn. |
| Key words: satellite navigation system one - way timing two - way timing precision evaluation |
