Virtual GPS is a GPS (Global Positioning System) simulator software. You can use it to emulate a GPS receiver unit connected to your computer. It's ideal when you need GPS input, but you have no signal or you can use it to test your GPS applications. It supports various NMEA 0183 sentences, so it can be used with any GPS mapping software. NMEA 0183 (or NMEA for short) is a combined electrical and data specification for communication between marine electronic devices such as echo sounder, sonars, Anemometer (winds speed and direction), gyrocompass, autopilot, GPS receivers and many other types of instruments. It has been defined by, and is controlled by, the US-based National Marine Electronics Association.
Supported NMEA sentences: GPGLL, GPGGA, GPVTG, GPRMC, GPGSA, GPGSV, GPZDA, GPWPL, GPRTE, GPAAM.
