Attitude Resolution Algorithm of Gyro-Free Inertial Navigation System

Abstract:

Article Preview

Gyro-Free Inertial Navigation System(GFINS) is constructed mainly with accelerometers. A nine-accelerometer GFINS scheme is designed and the prototype is manufactured. Then quaternion based attitude resolution algorithm is developed, the algorithm is also applied to the GFINS prototype, the results show that the algorithm can effectively offspring the cone-effect, and the attitude is resolute validly, the maximum attitude error is up to 0.37°, the maximum azimuth error is 0.47°.
