Abstract

The paper considers the problem of improving the accuracy of gyro stabilized system of airborne gravimeter during the survey. To reduce the stabilization error, a time-varying correction algorithm is proposed, which accounts for the heading error during the maneuver. Performance of stabilization system is studied with different models of heading errors. The proposed algorithm demonstrates critically reduced transient time as compared with the traditional time-invariant algorithm.
