Problems solved by technology

In practice, the orbit and attitude of the satellite deviate from the target setting, and the operating modes of equipment and heaters change randomly. These on-orbit variation factors cause a large error between the general thermal analysis results and the actual satellite on-orbit temperature field distribution.

Abstract

The invention provides a satellite on-orbit transient temperature simulation and prediction system which comprises a thermal control module, an orbit and attitude control module, a hardware interface module, a software interface module and a satellite thermal model module. The thermal control module is used for simulating the satellite thermal control management function. The orbit and attitude control module is used for simulating the satellite on-orbit working condition function. The hardware interface module is used for achieving conversion between data of the thermal control module and data of the software interface module and conversion between data of the orbit and attitude control module and the data of the software interface module. The software interface module is used for achieving protocol conversion for data communication with the satellite thermal model module. The satellite thermal model module calculates and analyzes the satellite thermal state according to the current satellite operation state and outputs a result. According to the system, data such as a satellite on-orbit operation orbit, the attitude of a satellite, the device working condition and a heater working condition can be received in real time, the thermal state of satellite on-orbit operation is simulated, temperature distribution in the satellite on-orbit operation process is predicted, and the thermal design function and the active thermal control functions of the satellite are verified.

Description

technical field [0001] The invention relates to a simulation and prediction system, in particular to a satellite on-orbit transient temperature simulation and prediction system. Background technique [0002] At present, the on-orbit temperature of satellites is mainly predicted by the method of thermal analysis. This method can only calculate a certain working condition by presetting the satellite orbit, attitude, heat consumption of on-board equipment, and power of the heating plate. In practice, the orbit and attitude of the satellite deviate from the target setting, and the operating modes of equipment and heaters change randomly. These on-orbit variation factors cause a large error between the general thermal analysis results and the actual satellite on-orbit temperature field distribution. Therefore, transient thermal analysis based on real-time on-orbit data is an ideal method for predicting the transient temperature of satellites in orbit. [0003] To achieve this fu...
