DWI releases GRPS Website User Interface

DWI is pleased to announce the release of the GNSS RAIM/RNP Prediction Service.
(http://www.dwint.com/Products/GNSS-RAIM-RNP-Prediction-Service) website user interface. The webservice can be found here: https://tools.dwint.com/grps/home.html.

GRPS supplies real-time RAIM predictions and RNP predictions to end users either through their existing flight-planning suites or, now, through the customised website user interface allowing airlines, ATC and ANSPs to perform RAIM predictions for their PBN operations from departure through enroute to approach and arrival, even for RNP approaches down to 0.1 NM. The web interface allows consumers of RAIM predictions with, typically, a lowload requirement (less than 100 predictions per week), to access the information they need with the minimum effort and cost.

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.
DWI has been operating GRPS since 2007 serving airlines, ANSPs and flight planning companies with a seamless, often integrated service with an availability in excess of 99%. As operators begin to use new constellations for their GNSS navigation, GRPS will be updated to allow for such predictions.
"We're approaching 5 years since GRPS went live and we're very proud of the service we have provided and shall continue to provide," said John Wilde, CEO of DW International. "A web-based user interface is the next logical step: As the number of GNSS-based procedures continues to grow, we want users to have access to RAIM prediction in whichever form suits them best."
KLM, based in The Netherlands, is the first user of the GRPS website user interface.
