Research On Spaceborne Attitude And Orbit Control Software Simulation Testing Platform

At present spaceborne attitude and orbit control software of the embedded software simulation testing platform is lack,it can guarantee the independence and comprehensive of the third party testing with independent testing platform. Anticipated goal of+this paper is to analyze the spaceborne attitude and orbit control computer peripheral interface, design and develop a set of spaceborne attitude and orbit control software used for testing the test platform. The platform can simulate the peripheral situation of spaceborne attitude and orbit control software, inject test data from the simulation application module of attitude and orbit control System environment and the injection module of remote data, view test results data from remote sensing data statistics module.The main work and major research results include the following:(1)The applications of the platform is dynamic testing of spaceborne attitude and orbit control software to verify the correctness of the software function, and the time performance testing etc. Some test cases with boundary value and abnormal value can be tested on this platform sufficiently. This platform can display, storage, playback and analyze test result. All the above applications can improve the adequacy, effectiveness and independence of the platform.(2)This platform will help the white box testing and coverage testing, increase test coverage. It solve the embedded computer software logic coverage testing requirements and difficulties.This platform puts forward the reasonable source code inserted pile expansion strategy to reduce space and time dilation by using the technology principle of the coverage test tools Macabe.(3) This platform can apply on other spaceborne attitude and orbit control software testing with a small amount of code modification,adding,and deleting,.It can simulate peripherals flexibly, which is advantageous for the extension.
