Target pointing is a function that maintains LOS(Line of Sight) toward a fixed ground target by controlling azimuth and elevation angles of electro-optical systems which are calculated from navigation data of aircraft and target coordinates. It is useful when pilots wish to observe the target continuously under dynamic maneuvering of the aircraft.
To guarantee the target pointing performance, target coordinates have to be estimated accurately. There are several error factors for computing the target coordinates such as alignment error, sensor measurement error control error, and so on. Especially, transmission time delay of the navigation data is a major factor. This paper describes the target coordinates estimation algorithm and shows its experimental results.
