The most outstanding feature is the high modularity of the components that enable integration of GPS-receivers into own software products.

Most commmon receivers (NMEA, Garmin, Trimble) are supported out-of-the-box but you can easily extend the library with own modules for exotic receivers.

The functions:
- Realtime receive actual position and other informations
- Coordinate transformations
- Up- and download of waypoints, routes and track logs
- Visual controls for many of the informations
