In measurement of airborne tensor magnetic

magnetic tensor gradiometer attitude change will cause the measured magnetic field gradient generate large fluctuations

influence the explanation for abnormal data and inversion. Using posture information measured by inertial navigation system for correction of tensor data

must assure inertial navigation data in strict accordance with the tensor data in collection time point

aiming at this problem

design a tensor gradient measurement system data synchronization aquisition technology

in terms of hardware

design PPS trigger mode of hardware acquisition; on the software side

introduce circular queue buffer mechanism for fusion processing of inertial datas and tensor datas. Experimental results show that the design of the system can correct attitude of gradient sensor very well.
