There are several levels of softwareti.e. flight
software) performance testing in spacecraft development. For
example, unit test, integration test and system test. Especially
the integration test is one of the key phases because in this
phase the flight software performance with respect to HW and
SW compatibility is validated. Also throughput analysis shall
be performed at the integration test level. To mitigate schedule
burden for performing the integration test, an approach using a
simulation test bed in the integration test is regarded as
enhanced and cost effective way. Also potential technical risk
can be minimized through the early detection of software
problem with regarding to the HW compatibility especially
thanks to the simulated test bench.
In this paper, an approach to the development and use of
simulated software test bench in flight software of spacecraft
application is present with respect to further geo-satellite
program.
