    摘要： Methods, devices, and systems are presented for compensating for gyroscopic drift in a stabilized gimbal system mounted on a vehicle. When the vehicle is parked and the gimbal is not being commanded to move by an operator, encoders or resolvers of the gimbal stabilized system are read and periodically read thereafter. When the vehicle begins to move or the gimbal is commanded to move, the last periodic reading of the resolvers is used to determine the amount that the gimbal has moved during the rest period. A gyroscopic drift rate is computed by dividing the amount of angular movement by the time period between the readings, and the gyroscopic drift rate is used for corrections while the vehicle is moving or gimbal is commanded to move. Each time the vehicle stops, the gyroscopic drift rate is re-computed and updated. The gyroscope can be heated until the drift rate is constant with respect to temperature, further helping the calibration.

    摘要： A two axis (azimuth and elevation) stabilized common gimbal (SGC) for use on a wide variety of commercial vehicles and military vehicles which are employed in combat situations capable of stabilizing a payload of primary sensors and of mounting a secondary sensor payload that is independent of the moving axes. The SCG employs three gyroscopes, inertial angular rate feedback for providing gimbal control of two axes during slewing and stabilization. In addition the third (roll) gyroscope is used for performing automatic calibration and decoupling procedures. In this regard, the SCG provides an interface for the primary suite of sensors comprising one or more sensors having a common line-of-sight (LOS) and which are stabilized by electronics, actuators, and inertial sensors against vehicle motion in both azimuth and elevation. Remote positioning of the LOS of sensors in the primary suite is also accomplished, with the SCG providing an inertial navigation system (INS) which provides navigation and which detects the LOS for the primary suite of sensors relative to the vehicle. The aforementioned stabilized gimbal employs unique features such as automotive gyro calibration and decoupling algorithm that increases the producibility of the system and the stabilized gimbal has the capability of being remotely controlled via its system serial link where commands may originate from devices such as radio links or target trackers.
