Pegasus - FRAME

Frame automation of the data processing easy access to all the data traceability of the process

EUROCONTROL Experimental Centre

Pegasus - MODULES

Convertor translate receiver-native data into a generic format receiver implementation Input - receiver data Output - ASCII data

WinGPSAll calculates a position solution and protection levels Input - Convertor files Output - data file (position and time solution data,

protection levels and position errors)

EUROCONTROL Experimental Centre

Pegasus - MODULES

Plausibility Check performs a number of user defined checks on the data input - modules data output - log file with check information rules

Aircraft Dynamics computes the position error for dynamic data input - position data output - error data reference data - provided externally

M-file runner - FileWatch visualization and detailed data analysis on the results
