DWI updates the GRPS Web User Interface

DWI updated its market leading GNSS RAIM/RNP Prediction Service (GRPS) Web User Interface last week to make obtaining RAIM Predictions even easier. Working closely with the GRPS user-base, typically airline flight operations or dispatch departments, DWI has implemented a number of refinements to the user interface as well as introducing brand new capabilities.

The new Dispatcher Tool gives the flexibility to perform an aerodrome RAIM check in a small browser window saving screen space for other applications; an important requirement for dispatchers with busy PC desktops to manage. The interface has been specifically tailored so that it requires only the key data that dispatchers require for their routine operations: aerodrome searchable by ICAO or IATA code, date & time, customisable GPS receiver configuration selection and PBN integrity level. The output has been simplified for the dispatcher's convenience, reducing the workload and streamlining the entire process.

The screenshots below show some examples of the simplified interface for dispatchers:

The enhanced data management feature allows closer control of the information resources used to create scenarios for predictions and alerts users to the provenance of stored data and to any alterations made to the data. The objective is to present all relevant information to the users at the time they perform a RAIM prediction requiring the minimum workload for dispatchers and maximum control for the user administrator.

DWI'sGRPS Web User Interfaceis being used by a growing number of airline operators and is part of the routine tool-set in many airline Operation Control Centres and dispatch teams.

"We work very closely with out customers and are actively involved in the roll-out of our tool to the end-user operations teams," said Head of Operations & Support, Kieran Conlon.

"Establishing a working rapport and pro-actively soliciting feedback from dispatchers, operation centre team leaders and end-user management teams has allowed us to get fantastic insight into what works best for the GRPS user community. A significant proportion of the latest updates to theGRPS Web User Interfaceare as a direct result of feedback that we received from our customers. The update has occurred within a remarkably short turn-around time and we are very pleased with the positive response we have received from our users."
