Galileo E1 OS/SoL acquisition, tracking and data demodulation performances for Civil Aviation

Abstract : This article presents a methodology related to the computation of civil aviation acquisition, tracking and data demodulation thresholds adapted to the case of Galileo E1 OS/SoL signal. These thresholds are compared against worst case link budgets representing operational scenarios. It is shown that these thresholds provide a positive margin although these theoretical results would probably require a deeper analysis and confirmation through extensive testing.
