The key elements of a noncommercial computerized flight inspection system designed for testing of basic air navigation ground facilities are described. Choice of proper power supply, connection of different receivers, their characteristics, antenna installations and data processing algorithms are discussed in detail. Aircraft ground tracking techniques are considered together with achievable positioning uncertainty. It is shown that a simple BASIC-programmed controller together with IEEE-488-bus equipment and a theodolite tracker can provide a basis for measurements according to ICAO Annex 10 requirements. A technique for measuring two-frequency ILS-installations with a combination of communication test receivers is illustrated.<
