What is GPS Scanning?
Once you have the scanner programmed, this feature will allow for preset scanning, making it easier and safer for you to monitor a specific area while you’re driving. The scanner, along with the GPS Receiver, will turn on and off each programmed group as you travel. How is this done? The ARCXT software allows you to set up a center point’s latitude and longitude for each group. Let’s say your home town is in group one, you can find the center point by simply entering your zip code in the software. You can set the scanning range anywhere from 0.5 to 100+ mile(s). As you approach X mile(s) of that center point, the group will become unlocked. GPS Programming will also work with trunking systems. If you set up the trunking systems with multiple sites, you can set up each site with a center point and range.
