A Simulation Analysis of Fixed-Wing Aircraft Approach using Differential GNSS

C.S. Dixon and R.J.W. Jeans

Abstract:	A simulation study of the GNSS navigation sensor contribution to performance in terms of accuracy, continuity and availability was conducted for UK’s National Air Traffic Services, and was presented at the September 1996 meeting of the ICAO All Weather Operations Panel (AWOP). The work focused on precision approach of fixed-wing aircraft using a residual range error model representative of code-phase differential GNSS. The purpose of the work was to illustrate the value of simulation methods, rather than to provide a statistically rigorous study. This paper highlights elements of the study undertaken, and includes additional work not published for ICAO. The paper presents results from simulated aircraft approaches to London Heathrow airport using a variety of navigation satellite systems, including Differential GPS, both with a frill and with a reduced constellation, and operation with a receiver capable of combined differential GPS and differential GLONASS navigation. Performance of the differential systems modelled is quantified in terms of the key parameters of accuracy, availability and continuity.
