Navigation information flow system simulating operation of satellite navigation system

Abstract

The invention discloses a navigation information flow system simulating the operation of a satellite navigation system. The navigation information flow system comprises a spatial segment i satellite models, a ground segment k monitoring station models, a master station model, j injection station models, a satellite orbit simulation module and a scheduling planning service module, wherein the satellite models receive the ground navigation data, processes and sends navigation data to the monitoring station models when the related equipment is available, the satellite orbit simulation module calculates the visual satellite models of the monitoring station models and collects the observation data, receives the observational information of the visible satellite models when monitoring equipment is available and sends the observation information to a master control station when a communication network is available, the master station model receives the observation information and processes and generates navigation data information when the related equipment is available to dispatch to related injection station models, and the injection station models receive the navigation data information and sends the navigation data information to target satellite models when both the business-related equipment and the communication network are available.

Description

technical field [0001] The invention relates to the technical field of satellite navigation systems and reliability engineering, in particular to a navigation information flow system for simulating the operation of a satellite navigation system. Background technique [0002] Due to the usability problem of the satellite navigation system, the usability analysis of the existing satellite navigation system model has the following problems: [0003] One is to only describe the performance of the satellite orbit change geometric configuration, and there is no relevant usability analysis for other performances in the information flow process in the satellite navigation system, such as monitoring performance and communication performance, that is, the lack of an organic combination of performance and usability. [0004] The second is to only describe the overall availability of the satellite navigation system. There is no single availability description for the entire information ...
