Demonstration of Viability of ARAIM for LPV and LPV-200 Service Using Flight Data

Kristy Pham, Tom McHugh, Frank Lorge

Abstract:	This paper presents the results of testing performed by the FAA William J Hughes Technical Center's Navigation Team using flight test data to explore the viability of ARAIM. Codeless L2 is used as a substitution for L5, with the assertion that L5 performance will be superior to codeless L2 performance. Specific topics investigated were: 1. ARAIM performance using flight data, 2. GPS broadcast URA bounding performance , 3. Multipath error model bounding performance, 4. Benefit of using longer carrier smoothing times, 5. Benefit of aircraft attitude as an input to the multipath error models, and 6. Benefit of carrier coasting. Receiver measurement data was collected using the FAA Tech Center's aircraft. The data was then processed through an offline implementation of the ARAIM algorithms. That software includes a ramp error injection capability. Additionally the multipath error model bounding was evaluated using the flight data.
