Long-time functioning of radioelectronic equipment, occupies most of the market. For radio-electronic equipment a long-term functionality preventive routine inspection and repair difficult or even impossible. Therefore, for such equipment are increased requirements for reliability. For creations satisfies these requirements taken a number of measures to ensure a margin of safety (mechanical, electrical, radiation, etc.); troubleshooting during acceptance testing - including using different stands. At the same time, increasing the role of methods and tools for monitoring and diagnostics - not just hardware, but also software, including the simulation and modeling of equipment failures. The article describes the features of the existing methods and tools intended for the monitoring and diagnosis of electronic parameters of the class of electronic equipment long-term functioning as on-board equipment. On the basis of mathematical models for assessing the reliability of the electronic means of electronic equipment long operation expressions are obtained for the maximum likelihood estimate provided that the interval between the manifestation of obvious defects. This made it possible to estimate the average time until the next defect of the electronic means of long-term operation of electronic equipment.
