GNSS Evolutionary Architecture Study. Phase I - Panel Report

摘要

This Report documents preliminary findings of the Global Navigation Satellite System (GNSS) Evolutionary Architecture Study (GEAS) Panel. The FAA Global Navigation Satellite System (GNSS) Program Office established an expert panel consisting of FAA, DoD, JPL, MITRE, academia, and industry personnel. The Panel developed candidates for an integrity architecture for modernized GNSS that would satisfy en route, terminal, and precision approach operations as low as 200AGL at 99.0% availability or better and be capable of providing LPV-200 performance worldwide. These architectural alternatives are based on an allocation of civil aviation requirements between space, user, and ground segments and identify conspicuous strengths and weaknesses with respect to technical, cost, schedule, operational, and institutional risks.
