Design and development for HSU-SAT1 sensor system

Abstract

HSU-SAT1 is a nano satellite currently under development at Happy Science University. This satellite will be equipped with a magnetic sensor and a gyro sensor. In this paper, the method of calibrating these sensor data on the magnetic sensor and gyro sensor required for the attitude determination of this satellite was examined. For the magnetic sensor, the sensor error was corrected and the origin was calibrated. The gyro sensor obtained the offset value from the sensor and made a correction. As a result, it was possible to make a correction that satisfies the required accuracy for the attitude stability of the satellite.
