Simulation Test System, The Icd-based Small Satellite Platform E-learning

The electronic emulation and test system of small satellite emulates a majority ofmanagement function when used in coalition debugging of electronic capability andsoftware testing on desks during a small satellite research. It also emulates interfaceenvironment on desks when other systems combine with the platform of the smallsatellite. Therefore the electronic emulation and test system is very important. Thekey of forming small satellite platform is that establishing expandable emulation andtest platform of electronic system on requests. The paper describes the need analyst of the electronic system, the systemstructure which is designed by ICD method, the procedure of software realization andthe result of validating the system during the course of realizing the electronicemulation and test system of small satellite. At the same time, it also introduces a kindof management software which is designed especially in order to be convenient toadminister the system. Compared with traditional emulation and test system, the predominance of thissystem designed by ICD is that it assures the unification of emulation and test,realizes auto-test, unifies the describing manner of interface protocol, puts an end tomisunderstand the protocol, ensures the flexibility of the system in a great degree.Since it improve the versatility, when other emulation and test system is needed, it canonly be added correlative hardware driver, and defined a suit of integrate ICDdatabase according to the system request. When all the data are inputted into the ICDdatabase using the ICD management tool, the application software can be developed,but other portions are not necessary revised. This kind of method changes thesituation that the emulation and test system can only be used one time.
