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

Abstract

The invention discloses an autonomous integrated monitoring system and method for a navigation satellite signal and a telegraph text. The system comprises an uploading signal monitoring module, a telegraph text generation and comparison module, a low-power navigation signal monitoring module, a high-power navigation signal monitoring module and a health judgment and processing unit. Through the uploading signal monitoring module, the telegraph text generation and comparison module, the low-power navigation signal monitoring module and the high-power navigation signal monitoring module, the integrity of an uploading receiving subsystem and telegraph text and signal integrity of an information processing subsystem and a high-power subsystem are monitored. And finally, through the health judgment and processing unit, according to monitoring results of the integrity of the uploading receiving subsystem and the telegraph text and signal integrity of the information processing subsystem andthe high-power subsystem, fault positioning is carried out.

Description

technical field [0001] The invention relates to the technical field of navigation satellites, in particular to the autonomous integrated monitoring technology of navigation satellite signals and messages. Background technique [0002] Navigation satellites are artificial satellites used to provide wireless navigation signals and navigation information, and provide users with navigation, positioning and timing services. The navigation satellite system has high positioning accuracy and a wide range of services. It can provide all-day, all-weather, and continuous navigation and positioning services. It has become a major national infrastructure in the field of space-time positioning and an important support for the status of a major country and strategic interests. [0003] The payload subsystem is the main payload for navigation satellites to provide navigation services. It receives the navigation information on the ground operation and control, and modulates the navigation in...
