Abstract

We have developed a technology allowing to automate all stages of testing of spacecraft command and measuring systems' functional characteristics and providing construction of complicated sequences of command test procedures and visualization of results. The command and measuring system is one of the onboard equipment’s key systems, its functions are support of command and software control of a spacecraft’s systems and devices and control of their condition from the Earth control complex. The Earth complex transmits telecommands and the command and measuring system performs their reception, primary processing and transmission to the onboard control complex for execution. Backwards, the command and measuring system provides transmission of the telemetry packages containing information about condition of spacecraft onboard systems and the results of telecommand performance. Implementation of the software for automation of testing command and measuring systems by a company-producer has shown the necessity to expand its functional abilities in the area of control and analysis of the logics of work of the equipment during Earth complex’s command and measuring control over onboard equipment. The command execution analysis must be performed together with tests on compliance of physical characteristics with technical requirements to the equipment. 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.
