Virtual GPS is a GPS simulator software. You can use it to simulate 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. It operates in two modes: simulator mode and file mode. In simulator mode the latitude and longitude coordinates are periodically
incremented with a defined step. In file mode the GPS data is loaded from a text file which contains NMEA 0183 sentences.
The GPS data is transmitted periodically to a serial port (UDP ports are also supported). To get the output of the simulator, you can use a null-modem cable
which interconnects two physical serial ports or you can use one of the virtual serial port software from the market, which simulate two interconnected
serial ports like: Virtual Null Modem, Virtual Serial Port Driver, Virtual Serial Port Kit, Advanced Virtual Com Port and others. Another possible
application of the software is to broadcast the output of the simulator through bluetooth.
