Problems solved by technology

[0003] Due to the tight coupling of satellite software and hardware in traditional satellite testing, it is impossible to provide the same software execution environment as that of satellites in orbit in a pure software manner, and can only rely on physical or semi-physical simulation desktop satellites for testing
Due to the different operating environments and different operating modes of the simulator, there are problems of inconsistent integration levels; and the existing desktop satellite satellites are expensive and limited in quantity, which cannot meet the requirements of multi-regional collaboration, distributed execution, and large-scale parallel testing.

Abstract

The invention provides a virtual satellite, and a software and algorithm test platform and method based on the virtual satellite, and relates to the technical field of virtual satellites. The platformcomprises a satellite control and state monitoring tool which carries out measurement and control on the virtual satellite and the injection of software / algorithm, and receives the downloading data of the virtual satellite, an internal test tool which monitors behaviors of the software / algorithm and performing performance test on the software / algorithm, and an external test tool which performs configuration item test and / or system test on the software / algorithm. The virtual satellite uses a data center as an interface to decouple a cloud computing platform simulator from a satellite platformsimulator and a load simulator. According to the invention, the integration degree of simulators can be improved through the virtual satellite; efficient sharing and reuse of test resources are realized through the monitoring tool and the test tools; and the problem that multi-region cooperation, distributed execution and large-scale parallel testing cannot be met in existing satellite testing issolved.
