Embodiment Construction
[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.
[0023] In order to quickly realize the satellite-ground time synchronization and restore the satellite to an available state, the present invention proposes a method for quickly recovering the satellite-ground clock difference by using an initial synchronization command. The satellite-to-ground clock difference can be adjusted without using phase modulation commands, and the satellite time and the ground time synchronization device time can be adjusted to within 1ms immediately to complete the precise synchronization of the satellite-to-ground time.
[0024] Assuming that the second pulse of the satellite is ahead of the second pulse of the ground, such as fig...
