The use of magnetic heading and true air speed measurements made on board civil airplanes to assist in radar tracking is described. The data are telemetered via the air-ground data link of the mode S radar system. A filter similar to the first-order Kalman filter is developed using velocity measurements to bias its prediction equations. This filter satisfactorily follows maneuvers, and estimates, in real time, the wind in the vicinity of the airplane. A scheme is described to remove false data due to data-link corruption.
