A description of the AFES is given, and its future expansion is considered. A microwave radar and an inertial system are currently the basic AFES sensors; in the airfield vicinity, up to a radius of approximately 10 km, they are supplemented by a laser tracker. All measurement signals are obtained in an online system on board the aircraft, using optimum estimation algorithms for highly accurate calculation of the reference path. The system has proven its merit in the testing of the following systems: inertial navigation and attitude reference systems, very high frequency omnidirectional range/Distance Measuring Equipment (DME); various integrated navigation systems; precision DME; geographic positioning system receiver; microwave landing system; three way DME (developed for flight guidance and control); and the 'image reconnaissance' experimental system. The following points are the subject of tests, particularly for navigation systems: coverage and accuracy, influence of faults, operation suitability, and system demonstrations. The means by which the reference path is determined is outlined. The accuracy of the AFES reference system is discussed.
