Abstract:

A simulation method of satellite temperature based on telemetry data on orbit is presented. Based on the telemetry temperature of thermal boundary, the relation matrix of satellite temperature is obtained by constructing the relationship between equipment temperatures and mounting boundary temperatures. By using the numerical calculation between the telemetry temperature of thermal boundary and the relation matrix of satellite temperature, on-orbit satellite temperature can be predicted. The calculation error is less than 2.5℃.
