3. Pegasus - FRAME Frame automation of the data processing
easy access to all the data
traceability of the process

4. 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)

5. 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

6. Graphical visualization: M-file runner
Visualisation - Matlab
Input - Convertor, WinGPSAll
Output - graphical presentations
