Method for managing and controlling inter-satellite links of navigation constellations according to running modes and scenes

Abstract

The invention discloses a method for managing and controlling inter-satellite links of navigation constellations according to running modes and scenes, which comprises the following steps of finely dividing the running modes and scenes of the inter-satellite links of the navigation constellations, and dividing the overall running modes of the inter-satellite links according to the overall construction stage and the service state of the inter-satellite links, dividing an inter-satellite link local operation scene according to the inter-satellite link local operation characteristics; enabling the ground comprehensive monitoring module to judge the overall operation mode of the inter-satellite link and each local operation scene of the inter-satellite link, and switch the overall operation mode and the local operation scene of the inter-satellite link according to the conversion relationship between the operation modes and the conversion relationship between the operation scenes; and enabling the comprehensive monitoring module to trigger a ground center computer system to execute a specific management and control function according to the inter-satellite link operation mode and the state output of the operation scene so as to comprehensively realize various inter-satellite link management and control services. According to the invention, the problem of networked inter-satellite link management and control of dynamic scale change and dynamic business development of an aerospace measurement and control system is effectively solved.

Description

technical field [0001] The invention belongs to the technical field of spacecraft measurement and control, and in particular relates to a method for managing and controlling navigation constellation inter-satellite links according to operating modes and scenarios. Background technique [0002] In order to realize the core functions of the global navigation system such as precise orbit determination and time synchronization, autonomous navigation, and monitoring and control of overseas satellites, an inter-satellite link with precise measurement and communication functions has been established between Beidou global satellite navigation system satellites. Inter-satellite link management and control mainly performs resource management and scheduling, status monitoring and fault diagnosis, performance testing and evaluation, etc. for the inter-satellite link, so that the inter-satellite link can operate in a coordinated, efficient and stable manner. The Beidou global satellite n...

AI Technical Summary

Problems solved by technology

[0007] The original measurement and control method oriented to the single target of the spacecraft has been unable to meet the management and control requirements of the networked intersatellite link

The original aerospace measurement and control system oriented to a scalable number of single-satellite services has great difficulty in directly adapting to the comprehensive management and control of complex inter-satellite links
