When conducting a GPS-aided survey, be sure to first configure AirMagnet Survey's GPS COM port so that it can communicate with your GPS device. You can use any NMEA compliant GPS device with Survey.

 1. Within the Windows Device Manager, select the computer name. Right-click and select Add Legacy Hardware:


2. Ensure that Ports (COM & LPT) appear; if they do not, please work with your IT Department to troubleshoot:

3. Ensure GPS drivers are properly installed and working on your GPS device; you may need to visit your GPS manufacturer's website to obtain the drivers:

If everything is properly configured and you are outside of any building, Latitude and Longitude data should appear in their respective windows. That means you are successfully using GPS data from your GPS device within AirMagnet Survey.

If Latitude and Longitude data do not populate this screen, double-check that your GpsGate Virtual COM port matches your Survey GPS Configuration and that you are outside of any building.
