There is "freeware" that will display the output of your GPS on your computer - VisualGPSâ„˘
This is a good way to confirm that the GPS output is really getting into the computer. You can open the programs NMEA
sentence window and watch the actual GPS sentences being downloaded to your computer. It also has current
position and accuracy windows plus more to see how the GPS if performing.
- - With any new installation
of a computer navigation
program I also install the Visual GPS program to be sure that the GPS is "talking" to the computer before trying to "install/activate" the GPS in the navigation
- - One limitation is that you can only utilize one program that will be using the GPS at a time. You cannot run the navigation program and a GPS utility program at the same time - at least not on any computer I have used.
- - There is an old time problem that affects Windows operating systems and GPS's - and that is that the operating system can think that the GPS signal is a "mouse" signal and it causes strange things to happen especially with the cursor. The work-around was to start the computer without the GPS turned on or plugged in and also the navigation program - and then turn on or plug
in the GPS to the computer. It was also common that once the navigation program was shut down that other programs with "comm" port provisions would go weird if the GPS was still turned on.
