The key element of modern spacecrafts is high-precision antennas. Therefore the antenna guidance system (AGS) is present practically on any spacecraft (SC). Great demand is placed on AGS on each SC. Ground experimental method of antenna guidance system includes a set of stages and types of testing, but it isn't always enough of them for identification of short-term failures. Modern control modules of antenna guidance system (AGS CM) have various variants of construction. The option of AGS CM creation used on SC with active lifetime more than 15 years is considered in the article. With the offered option of the device creation as ground experimental method showed, short-term failure of command transmission is possible. For identification of such single failures the method of load testing which is usually used when testing the software of client-server applications and complicated IT- systems was used. The special test software was developed for probe of the device, and also imitating program model of angle conversion block. This development allowed revealing single failures when commands transmitting for change of speed of rotation of the antenna on the MIL-STD 1553B interface, and also to check and confirm possibility of rejecting such failure. Such method of testing can be applied during tests and probes of any components of SC in which data transmission through the MIL-STD 1553B interface is used.
Keywords: load testing, development of software, test, onboard equipment, spacecraft.
