GPS simulator for software testing

**Zip-Lock** · 03-15-2004, 01:27 PM

I’m trying to develop a custom GPS app and don’t want to rip the GPS out of my car just to test it. Is there something to emulate the serial port and NMEA data?

In mine I just captured the NMEA data as I drove then I play it back from a file calling the parsing mechanism for each line I read.

NMeaTool works well.. it's really touchy getting it to work but once you can make yourself a script you can load it works well. For the serial port get a null cable or use one of those virtual serial port emulators.

I think he was asking what d'you use to play it back!

I've had this problem and I thought I would post this to here just in case anyone needs the answer

You need: http://www.lichtenheld-mch.de/GPSsim_E.htm - 'GPSSIM' and either a null-modem cable between two serial ports (One for GPSSIM to send the fake GPS down and one for the navigation program to use) or a trial for a virtual version such as 'VSPD' - download a trial from http://www.mks.zp.ua/vspdxp.php
