Abstract：Through the aeromagnetic survey of the power glider in Duobaoshan area, the authors evaluated the function and characteristics of the powered glider aeromagnetic system. The comparison of measured data and the processing analysis of graphic data in different flight directions on the same measuring line indicates that there is no lag and no direction difference in the data, and the three-component magnetic compensation system is relatively complete. The working accuracy is 4.0nT by using the repeated line data as the check data, the inspection data of the same spatial position with the check points can be obtained by means of interpolation and height extension. The demonstration results indicate that the powered glider aeromagnetic system has the characteristics of portability, high efficiency, high adaptability and high precision.
