It has autodetection of data format (so it works both in NMEA or SIRF with on the fly detection). It can display statistics and data panel for cockpit use. Cockpit mode includes history graphs for speed and altitude.

Program is able to tweak GPS receivers by changing the operation mode or resetting the device. It can save output from GPS to a dump file and save comprehensive debug information.

Screenshots here should give overview of the application.

Note:
- The same executable works on PC/Windows and Pocket PC etc. You can run the same .exe file on all platforms.
- No need to install the application, just copy to any folder and run it.
- Works with VGA and QVGA displays. DOES NOT WORK ON SMARTPHONES. To be exact - it works but the user interface was designed for rectangular screen, not for square one.
