Background. The introduction of new means of technological equipment for the processes of experimental research of on-board radio-electronic equipment of satellite control systems at the stages of its production and operation support necessitates updating the corresponding methodological support, taking into account the formed directions of digitalization in the rocket and space industry. Materials and methods. A new technical solution for the hardware-software emulator of interface modules is implemented on the use of hardware-software resources in the time-sharing mode. The introduction of the emulator into production activities increases the degree of automation of the production processes of the enterprise, and new methods of its application implement the mechanisms for information support of the life cycle processes of the onboard radio-electronic equipment of satellite. Results. A hardwaresoftware complex has been developed, its provide emulation of the operation of eight interface modules for the computing module of the onboard equipment in hard real-time mode based on one set of technological equipment. The functionality of the emulator provided an increase in the information content of the ongoing research of the equipment due to the possibility of implementing extended test methods (imitation of failures of equipment units, debugging the mode of autonomous preservation of the attitude of the satellite, working with backup sets, etc.). Methods for using the emulator as a means of technological equipment for applied experimental research on the onboard radio-electronic equipment of satellite at the stages of its design and operation are proposed. Conclusions. The implementation of a hardware-software emulator of interface modules into the organizational and technical system of the enterprise in combination with new methodological support for the processes of applied experimental research made it possible to: implement the mechanisms for integrating and managing service data about the product within the framework of a single information space of the enterprise; to improve the quality of ground experimental testing of equipment at the stages of design and operation; reduce material costs for the necessary technological equipment for testing; reduce the influence of the human factor on the reproducibility of test results; as well as to improve the fault tolerance of spacecraft as a whole at the stage of their operation.
