Pegasus - FRAME

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

4
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)

5
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

• MFile Runner
• Visualisation - Matlab
• Input - Convertor, WinGPSAll
• Output - graphical presentations

7
