In order to solve the problem of low accuracy and efficiency in the calibration of aeromagnetic compass, a set of calibration system for various aircraft compass based on Android system is designed. The system is composed of cockpit display and control unit, tractor display and control unit, reference compass unit, etc. each unit communicates through WiFi wireless network. The magnetic compass, fiber strapdown attitude and radio compass on the aircraft are calibrated accurately. The accuracy of calibration equipment shall be no less than 0.5 °, and the power supply of equipment shall be provided by lithium battery for no less than 8 hours. For the first time, two calibration modes, 8-point calibration and 12-point calibration, are used in the calibration, which greatly improves the accuracy of compass calibration. This system has low requirements for compass calibration site, low manufacturing cost, clear operation interface, simple logic structure and high technology content. Through the calibration of multi model compass, it is determined that the time is shorter, the efficiency is higher, and the labor intensity is lower than that of the traditional compass.
