I wasn't sure if I should post this in the Android Tablet area or here, but here goes. What devices currently share live GPS data in real time to one another?
The application for this is ATVing and quite often we are in areas that don't have cellular coverage. However, with Garmin and other GPS devices able to receive GPS data. As well as smartphones having GPS receivers, I am pretty much wide open on what ever devices that might currently do this.
For example, are their any Android apps that allow users to share their location and have it display in real time on a map?
I know that amateur radio has APRS allows this, but I don't think any of those are in an all-in-one device.
There may be something in marine radios that allows sharing of GPS data with other mariners.
The next step for this would be to take it from cellular based to two way radio based. I know that the FCC is going to allow data transmissions on GMRS, so that would be the likely service, since most of the members of our ATV groups doesn't have an amateur radio license.
Garmin Inreach Devices (formerly DeLorme technology) can transmit short text messages through the GPS Satellite network, but it is very limited and expensive. Otherwise, most real time location sharing that I am aware of is done through the cellular network. Maybe others know of different solutions.
Minor correction: Garmin Inreach messaging is thru the Iridium satellite communications system.
Thanks for the correction.
The Garmin Rino 7XX series 2 way radio's have this capability. In addition to location sharing, they also have the advantage of being able to talk to others in your group via FRS/GMRS radio.
Pricey to be sure, but they are on sale at the GPSstore for $100 off.
The group I hunted with a few years ago all used an earlier version of the Rino. They work very well for keeping track of, and communicating with others in the party. No cellular service is necessary.
