Method for monitoring the performance of spaceсraft payload in real time

A method is proposed for monitoring the performance of spacecraft payload in real time. The method is based on analyzing of the equipment state and sensor readings, and detecting unlikely rare combinations of the recorded parameters as potentially dangerous for the equipment. It is noted that the method is universal, that is, it can be applied to any type of controlled parameters, regardless of the method of their registration and physical dimension. Also, the method does not require preliminary calculation of maximal values (thresholds) for the controlled nodes. Specific examples are considered based on the data obtained during the operation of spacecraft equipment and during scientific space experiments. The results obtained can be used to increase the active lifetime of spacecraft, including multi-satellite constellations and CubeSat-type devices.
