A Method for Identifying Static Characteristics of High Precision Temperature Measurement on Orbit

With the development of satellite high precision temperature measurement and control system, the single step response of satellite temperature shrinks and the measurement precision exceeds the measurement accuracy. As a result, the temperature step response termination condition of conventional satellites cannot be applied to such satellites, which affects the test and experiment of high precision temperature measurement and control system. In this paper, according to the theoretical response equation of the unit step function of the first-order system, combined with the time constant, according to the static characteristics of the temperature response, the process of response discrimination and response termination conditions are given, and the static characteristics balance criterion of the high-precision temperature measurement and control system is given to some extent.
