The infrared radiation characteristics of satellites are of great significance for the discrimination between working satellites and failure satellites. According to the positional relationship between satellites and the earth and the sun, the direct solar radiation angle coefficients are calculated, and the stochastic simulation method is used to calculate the values of the earth’s albedo and the earth’s infrared radiation angle Coefficient, the satellite temperature control equation is established, and the concept of radiation transfer coefficient and Monte Carlo method are used to calculate the radiation heat transfer. The satellite temperature field is solved and the calculation method of satellite infrared radiation characteristics is discussed. The results show that the radiating surface of the satellite is the basis for distinguishing the working satellite from the failed satellite.
