SYSTEM FOR ACTIVE BORESIGHTING CORRECTION FOR EXTERNAL AIRCRAFT SENSORS

Abstract: a system for active boresight correction of aircraft mounted sensors includes inertial sensors mounted proximate to aircraft sensors rigidly coupled to structural components of an aircraft, the inertial sensors likewise rigidly coupled to the structural components and subject to substantially the same inflight motion and/or deformation as the structural components and aircraft sensors (which may affect the accuracy or precision of the aircraft sensors). each inertial sensor determines a sensor boresight based on a proximate aircraft sensor and any inflight motion or deformation to which the aircraft sensor is subjected. the boresight correction system determines an angular offset of the sensor boresight relative to the aircraft boresight, allowing for real time or near real time correction for motion or deformation of any data sensed by the aircraft sensor.
