Aerospace systems occupy an important place in the information, telecommunication, defense infrastructure of the country. These systems have strict requirements for safety and reliability. The study of dependability allows you to find the distribution of device operating time to failure. This is especially important for the non-recoverable onboard equipment of aerospace systems. Practice shows that even 5 years of active life is difficult to achieve, and for profitability it is required to ensure 2-3 times more. For such a period of operation, the radio transmission devices of spacecraft are exposed to prolonged exposure to ionizing radiation of natural origin. This leads to accelerated aging of materials, degradation of parameters of the electronic component base and single effects of failures and failures in semiconductor devices and integrated circuits, which must be taken into account when analyzing the reliability of newly developed and modernized devices.
