Abstract-This article suggests an approach to automation of spacecraft onboard equipment testing, basing on a formalized sequence of scenarios determining measuring and control actions. We have developed a technology allowing to automate all stages of testing of spacecraft onboard systems' functional characteristics with the help of testing equipment's software. We have described the functions of software at the stages of test planning, preparation and execution, processing of the results and producing reports. This approach extends the possibilities to conduct experiments and allows to justify design solutions.

Abstract. This article considers solution of the problem of testing of command and software management of spacecraft onboard equipment. The object of control is the command and measuring system which performs reception, processing and transmission of commands for interaction between an Earth control complex and spacecraft onboard systems, as well as transformation and transmission of telemetric information about the condition of onboard units. In order to build testing procedures we have designed software allowing to simulate external command and software management by setting different sequences of commands, controlling their execution and analyzing the received data. This approach extends the possibilities of conducting tests, allows to reduce the time of testing and improve the quality of designer solutions.

Abstract. In this article we present the integration technology of spacecraft onboard systems' simulation models in original infrastructure of simulation modeling based on the international Simulation Model Portability (SMP2) standard. We have described the technological stages of metamodel building to unite onboard systems' models in a one complex solution. This technology allows to build simulation models in terms of the subject area and provides their translation into software components working in accordance with SMP2 standard. Simulation models' realization in infrastructure will make it possible to provide creation of complex solutions and will help accumulation and usage of expert knowledge about spacecraft onboard equipment function.
