摘要:
A method for reducing effects of vibropendulous errors within a sensor device having three orthogonal sensors is described. The method includes calculating compensation terms for each sensor, the compensation terms associated with an angle between a pendulous axis for the sensor and a cross axis of the sensor, and subtracting the compensation terms for each sensor from data received from that sensor.

The illustrative embodiments provide a method and apparatus for stabilizing an electronic rack structure. In one embodiment the apparatus comprises an enclosure with a user interface panel. The apparatus also comprises a gyroscope, sensor system and controller attached within an enclosure. A sensor system associated with the gyroscope is capable of detecting a tilt of an electronic rack structure. A controller is also located within the enclosure and is capable of detecting the tilt of the electronic rack structure and controlling an orientation of the gyroscope to counter the tilt of the electronic rack structure in response to detecting the tilt. In another illustrative embodiment, a method for stabilizing an electronic rack structure is provided.
摘要:
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.
