  • Patent number: 9243931
    Abstract: Methods, devices, and systems are presented for calibrating or otherwise correcting the pointing accuracy of a gimbal. Measurements of the actual planes of rotation of each of a gimbal's rotatable elements is made using an off-board measurement device, such as a coordinate measuring machine (CMM). The measurements from the off-board device can be combined with those from native, on-board gimbal sensors of the rotation angles at which the planes are tilted/pitched with respect to their nominal planes of rotation. Information representing the error vectors between the nominal and actual planes of rotation is stored and used for correcting the pointing accuracy of the gimbal. The corrected pointing vector of the gimbal can be combined with measurements from an inertial measurement unit (INU) and rangefinder in order to accurately determine a geographic target position to which the gimbal points.

  • Patent number: 9032859
    Abstract: Multiple independently gimbaled devices, such as an electro-optical sensor and machine gun, are mounted to a rotating platform on a vehicle. The platform can rotate to prevent one device from blocking the other while aiming at an off-board location. A control system can harmonize the rotation of the device gimbals and rotating platform so that they remain pointed at the same location. The platform can be rotated to place a firing weapon downwind of a sensor or otherwise compensate for effects of one on the other.

  • Patent number: 6396235
    Abstract: 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.
