Problems solved by technology
[0009] The traditional ground-based telemetry integrity judgment method is limited by the telemetry channel capacity telemetry data, and many faults cannot be directly determined by the faulty single machine. At the same time, it takes a long time to judge the fault, which makes the fault recovery time long, which in turn affects the navigation satellite. availability and continuity
At present, some studies have provided some satellite autonomous integrity monitoring solutions, but these solutions cannot achieve system-wide monitoring and stand-alone-level positioning within the system
