Gyro Stabilization System of a Gravimeter

Features of the stabilization system of a gravimeter used on board aircraft are considered. In error analysis of the system, the scaling errors of the gyros and accelerometers are considered along with the errors in the orientation of their measuring axes relative to the gyroplatform axes. The results from simulations are presented. The problems of selecting the correct stabilization system response time to achieve the most efficient gravimetric survey are discussed. Recommendations on the accuracy of orienting the measuring axes of the sensitive elements are given. The influence of the aircraft maneuvering parameters on the accuracy of the system is considered.
