Global Positioning System (GPS) Receiver Analysis Tool (RAT)MSC-24649-1RAT reads telemetry information from a GPS receiver and determines the receiver’s performance. As atelemetry-input file is read, an analyst can see the plotted satellites and telemetry information change inanimated form. The analyst can halt the animation and generate high-quality PostScript images of the plotsuitable for importing into post-flight reports.U.S. Government Purpose ReleaseGlobal Positioning System (GPS) Satellite Geometry Analysis Tool (GPSGEM)MSC-24625-1GPSGEM evaluates satellite geometry for a given Earth-fixed location or trajectory, provides a listing of all GPSsatellites in view, and extrapolates a vehicle’s trajectory even if two satellites are removed. The tool’s navigationcontrollers offer insight into expected GPS constellation performance and assess implications for the ascentabort and entry phases of a flight. With GPSGEM output, analysts can determine if GPS constellation geometryis robust enough to support vehicle GPS receiver state solutions and/or accurate enough for a safe landingeven if one or two satellites fail.U.S. Government Purpose ReleaseGoddard Mission Services Evolution Center (GMSEC) ArchitectureGSC-15142-1From development through operations, the GMSEC Architecture provides a secure, scalable, extensibleground and flight system for existing and future missions.
