| Abstract: | On the basis of a sinusoidal model of the disturbed horizontal acceleration, the spectrum characteristics of misaligned angle and horizontal acceleration correction are analyzed. In an airborne gravimetry test, the misaligned angle of platform and horizontal acceleration correction are calculated. They are 5′ and 3 mGal, respectively, when the flight is stable. |
