Organization of tests of integrated on-board spacecraft control system

The experience accumulated by a test organization of integrated on-board control systems of spacecraft for scientific purposes, which became the basis for all the latest developments at Lavochkin Research and Production Association in the implementation of advanced space programs, is analyzed. At this enterprise, the proposed methods of test organization have made it possible to take a step toward developing the technology of scientific spacecraft testing based on new principles of the modern development of electronic and software systems used as block and unit devices (BUDs) and separate on-board systems.
