Ground based boresighting techniques are used to install a line-of-sight sensor on an aircraft in order to align the sensor axes with the aircraft body axes. Due to the limitations of the calibration equipment, residual boresight errors often remain which degraded the system performance. This paper presents a method for in-flight calibration of the boresight errors of a line-of-sight sensor as an alternative to the less precise and more expensive conventional methods. This in-flight method employs a Kalman filter to estimate the boresight errors based on the difference between the expected and measured line of sight of a sight, and the azimuth and elevation angles of the sensor gimbals define the measured line of sight. The accuracy of the shipboard INS/GPS navigator is sufficient to make the analytic calibration practical. The results from flight tests show the benefit of this application of Kalman filter technology.
