The FAA has established a program to demonstrate the feasibility of differential GPS (DGPS) based technology for Category (CAT) IIIb precision approach and landing applications. DGPS includes code corrections and phase differencing or phase correction (real-time kinematic) techniques. Contractors will provide complete systems including ground reference and signal monitor equipment, ground-air data link, and an aircraft instrumented with DGPS receiver/processor driving a flight director/autopilot. Several contractor systems are expected to undergo flight testing and optional satellite simulator testing. This Level 1 plan describes the test concepts and objectives, and also outlines the preparation of Level 2 and Level 3 Test Plans. The primary objective of the flight test is to demonstrate whether a contractor is DGPS system meets either sensor accuracy requirements for CAT IIIb approaches or the total system error requirements of the new tunnel-in-space concept. Additional objectives are to demonstrate adequate integrity and continuity of service. This plan describes specific objectives, guidelines and measures of success (MOSs) for the flight tests. The primary objective of the optional satellite simulator testing is to determine the robustness and integrity characteristics of a contractor's system in response to variations in satellite signals that cannot readily be produced during flight testing. This plan describes specific characteristics to be measured by the satellite simulator testing. Differential GPS, Precision approach test plan.
