Abstract

The invention provides a time integrity monitoring method, relates to the technical field of satellite navigation, and aims to solve the technical problem that a control part of an existing global satellite navigation and positioning system is relatively long in troubleshooting time of a fault satellite. The time integrity monitoring method comprises the steps of: setting local position coordinates and time service precision requirements; selecting a plurality of satellites in the same satellite navigation positioning system; acquiring a clock error of each satellite; judging whether a fault satellite exists or not, and if the fault satellite exists, eliminating the fault satellite; and determining a temporal quality state. According to the time integrity monitoring method, the time for troubleshooting is short, and the time quality state of the satellite navigation and positioning system can be obtained after troubleshooting of the faulted satellite.

Description

technical field [0001] The invention relates to the technical field of satellite navigation, in particular to a time integrity monitoring method. Background technique [0002] Global satellite navigation and positioning system time measurement has been widely used in various fields such as scientific research and engineering technology, and has become the most important high-precision time measurement method. The time measurement of the global satellite navigation and positioning system is based on satellite atomic clocks for time measurement. Once the satellite clock of the global satellite navigation and positioning system fails, it will seriously affect the time measurement results, and even cause the system to stop working. [0003] Although the current global satellite navigation and positioning system already has high reliability and availability, for unpredictable faults, the processing time of its control part to troubleshoot the satellite is usually 5-45min, which i...
