PEGASUS: A frame for GNSS Data Evaluation ICCAE Course – Software Outline PEGASUS: A frame for GNSS Data Evaluation
Pegasus – A frame for GNSS data analysis Structure Main Frame Modules Data Logging CONVERTOR Plausibility check WinGPSAll Truth Ref MFile Runner Data Recording Data Processing Steps Rx D E C O I N G Data Transfer Raw ASCII P L A U S B T Y Storing Checked M Output Production
Pegasus - FRAME Frame automation of the data processing easy access to all the data traceability of the process
Pegasus - MODULES Convertor WinGPSAll 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)
M-file runner - FileWatch 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
