High-fidelity satellite fault simulation method for navigation satellite platform

Abstract

The invention discloses a high-fidelity satellite fault simulation method for a navigation satellite platform. The navigation satellite platform includes a main processing module and various subsystem simulation modules attached to the main processing module, and fault simulation model units are preset in each subsystem simulation module. , adding a fault information processing unit to the main processing module; after the fault information processing unit compares the satellite fault information, it distributes the satellite fault information to the corresponding fault simulation model unit in the subsystem simulation module, performs fault phenomenon simulation, and finally performs fault Solution injection and validation. The invention simulates satellite on-orbit fault phenomena, and responds to faults through telemetry to provide a basis for fault analysis; executes a fault solution plan, verifies the correctness of the fault solution, and provides powerful help for satellite fault elimination.

Description

High-fidelity satellite fault simulation method for navigation satellite platform technical field The invention relates to the technical field of satellite fault simulation, in particular to a high-fidelity satellite fault simulation method for a navigation satellite platform. Background technique With the development of science and technology, the scope of space missions has become wider and wider, and the application of satellites has penetrated into all aspects of human activities. At the same time, satellite failures continue to occur, affecting the normal operation of satellites. These failures cause satellite performance degradation, function loss, or even scrapping, which brings huge losses to users. Therefore, it has become an important research direction to quickly analyze the fault when the satellite fails, and then find a solution to the fault. Contents of the invention The purpose of the present invention is to solve the fault simulation problem of the high...
