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.
A system for active boresight correction of an aircraft sensor, comprising:
An aircraft-based active sensor system capable of self-correction of a sensor boresight relative to an aircraft boresight, the aircraft boresight indicative of a three-axis angular orientation of an aircraft, the aircraft having an aircraft inertial reference unit (IRU) configured to determine the aircraft boresight, the active sensor comprising:
An aircraft-based method for correcting a boresight for an aircraft sensor disposed on a structural component of an aircraft, the method comprising:
