GPS over BlueTooth allows you to connect your mobile phone as an external GPS receiver that can transmit information about satellites and the current location using Bluetooth to computer.
This will help you to work with such programs as: SasPlanet Google Earth OziExplorer 2Gis and
other navigation applications.

Additionally you can view a map of "satellites" which are used to determine the current position and the signal strength from them.

At the moment for transmission of information the application uses the data transfer protocol - NMEA 0183.

The application supports the following NMEA messages:
GPGGA - Global Positioning System Fix Data
GPGLL - Geographic position latitude / longitude
GPGSA - GPS DOP and active satellites
GPGSV - Detailed satellite data
GPRMC - Recommended Minimum Specific GPS/TRANSIT Data
GPVTG - Track made good and ground speed
GPZDA - Date and Time
