How it Works
GRPS supplies real-time RAIM/RNP predictions direct to end users through their existing flight-planning suites. It is fully automated so that flight planners obtain the RAIM prediction as they plan the route. The service allows flight planners, dispatchers and aircrew to plan around periods of reduced GNSS availability by taking all route details from the flight plan and calculating RAIM availability for all route types – oceanic, en-route, terminal, and approach – on a leg-by-leg basis, including destination and alternate airports for RNAV and RNP operations anywhere in the world.
