In this article, we present the software for organization of complex testing of a spacecraft’s command and measuring system. The command and measuring system is responsible for communication of a spacecraft with the ground control complex. The developed software is designed for the support of interaction between the automated testing complex of a spacecraft and test and control equipment of the command and measuring system. Complex tests include testing of all or a part of conjugate elements of a spacecraft, united in a single system, with simulation of regular and possible non-standard modes of operation. Complex tests of the command and measuring system are carried out using an automated testing complex, the main task of which is transferring of the control commands to the test and control equipment of the command and measuring system. The automated testing complex also receives packages from the test and control equipment containing telemetric information about the state of the on-board systems of a spacecraft. During complex tests of the command and measuring system, the developed software supports the exchange of command and telemetry packages between the automated testing complex and test and control equipment. The developed software is built in the software of the test and control equipment as a subsystem for organizing of complex testing. The subsystem receives commands from the automated testing complex, identifies and sends them to the test and control equipment, in the form of a structure that is understandable to the command and measuring system. For each command, the subsystem produces a receipt of successful identification or of an error if it occurs. The subsystem receives telemetry from the command and measuring system, converts it in accordance with the protocols of interaction and sends it to the automated testing complex. In addition to the command and measuring system’s telemetry, the telemetry of the test and control equipment is sent to the automated testing complex. It contains the parameters of the sensors of various equipment that are part of the hardware and software complex, as well as the parameters required for transmission channels’ settings between the test and control equipment, command and measuring system and other systems of a spacecraft. All actions occurring during the process of complex testing are recorded in the test report. All protocols of tests are saved and can be replayed.
Keywords: spacecraft, command and measuring system, complex testing, test and control equipment, telecommands, telemetry.
