The use of airborne measurements to assist in three-dimensional (3-D) tracking is investigated and a simple filter is developed. This filter is derived from an earlier, flight-dynamics-based 3-D tracker, through simplifications. The performance of the simplified filter is evaluated using real data, is compared against the performance of the initial 3-D tracker and is found to be very satisfactory, while its computational requirements are significantly reduced
