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.
