CORRECTION ALGORITHM OF GYRO STABILIZED SYSTEM FOR AIRBORNE GRAVIMETER

摘要

The problem of gyro stabilized system disturbance damping for airborne gravimeter in maneuvering mode is considered. The time-varying data processing algorithm for corrected gyro vertical using satellite-based velocity measurements is offered. This algorithm takes into account the existence of heading error in maneuvering, has a simple form, and is based on solving Riccati equation. The simulation results show the efficiency of the proposed approach.
