This paper introduces the development and integration of the aeromagnetic measurement system for unmanned helicopters. Through integrated assembly testing for unmanned helicopter flight platform and aeromagnetic survey instrument and its magnetic interference testing and magnetic compensation testing, successfully integrate the aeromagnetic instrument with the unmanned helicopter flight platform to develop an aeromagnetic measurement system for unmanned helicopters. The system has completed flight test and flight application work. Compared with the contour map of previous geomagnetic anomalies in measuring area, the reflected geomagnetic field characteristics in aeromagnetic anomaly contour map obtained in flight application are basically the same which proves the effectiveness of the system. The unmanned helicopter aeromagnetic measurement system provides an efficient, convenient and scientific means of work for small exploration blocks with complex topography and harsh environment which need to be carried out aeromagnetic measurements survey.
