GPS Policy - GPS Evolutionary Architecture Study (GEAS)
The GPS Evolutionary Architecture Study (GEAS) panel was formed to define and evaluate Global Navigation Satellite System (GNSS)-based architectures to provide robust localizer performance with vertical guidance (LPV)-200 service worldwide circa 2020-2025. The approach for this study is to define the most optimal and cost effective distribution of signal fault monitoring responsibility between the space, ground, and user segment. The corollary objectives for GEAS are as follows:
The GEAS panel consists of experts from the Federal Aviation Administration (FAA), Department of Transportation (DOT), GPS Directorate (GPS-W), National Security Space Office (NSSO), Jet Propulsion Laboratory (JPL), academia (Stanford University, Ohio University, and Illinois Institute of Technology), MITRE, Zeta, and government support contractors. The GEAS panel is co-chaired by Professor Per Enge (Stanford University) and Deane Bunce (FAA).
