A Redundant Design Method for Small-satellite Temperature Measurement System

In order to increase the accuracy of temperature measurement and control system of small satellite, a redundant design method is presented, which is based on multi-sensor data fusion. Traditional redundant design method in small satellite design uses spare hardware, therefore greatly increases the power consumption, volume and weight of the satellite. The proposed redundant design method overcomes the shortcomings of traditional design method. In this design method, multi-sensor data fusion algorithm is used to give the reference value for each sensor in every group. Finally, experiments ware carried out. The experiment results indicate that this redundant design method can significantly increase the reliability and stability of temperature measurement and control subsystem with less spare hardware.
