A navigation satellite time system and its autonomous recovery method are provided, including a load time system, the load time system is configured to generate and maintain the load time, and the load time system comprises an space borne atomic clock, a time-frequency processing unit and a plurality of load time backups module, the time information of the load time is obtained from the ground station time; the pulse-per-second signals of the load time are generated and maintained by the space borne atomic clock and the time-frequency processing unit; when the time-frequency processing unit fails, the first-level recovery state is triggered: the time-frequency processing unit compares the time information and the pulse-per-second signals reversely output by the multiple load time backup modules to perform load time recovery.
