Progress of Joint Inversion on Geodesy and Geophysics

Based on assuming that the disturbing horizontal acceleration is a cosine function of time,the magnitudes of the misaligned angle,the average HACC and oscillating amplitude of the instantaneous HACC are estimated,respectively,and discussed in the frequency domain.Two methods of calculating the horizontal acceleration corrections are suggested in this paper.Finally the misaligned angle and the horizontal acceleration corrections for actual flight data are determined.
