System and method for north finding
First Claim
1. A payload including a gimbal assembly and associated gyro assembly, comprisinga gyro assembly control associated with said gyro assembly and operable to trigger the gyro assembly to obtain deviation measurements in the azimuth plane and elevation plane and process the measurements in a first dynamic range corresponding to a first rotation rate range, for stabilizing the payload utilizing said gimbal assembly;
- the gyro assembly control being operable to trigger the gyro assembly to obtain instantaneous measurements from an elevation rate gyro and process the measurements in a second dynamic range corresponding to a second rotation rate range having more sensitivity than said first dynamic range, for finding deviation of the payload from the north of the earth.

Abstract
A payload including a gimbal assembly and gyro assembly that includes a gyro assembly control associated with the gyro assembly and operable to trigger the gyro assembly to obtain deviation measurements and process the measurements in a first dynamic range for stabilizing the payload utilizing the gimbal assembly. The gyro assembly control is operable to trigger the gyro assembly to obtain instantaneous measurements and process the measurements in a second dynamic range having different sensitivity than the first dynamic range, for finding deviation of the payload from the magnetic north of the earth.
