could u give us the circuit please!! its really cool..

[phloey12]

range depends on way to many factors to list.

In a good steel and concrete building, it would come closer to being measured in feet than miles. In a valley, the range would be measured in miles, but not many. In a balloon at a few thousand feet it might be measured in terms of states.

Neat

would you be willing to share info on the GPS Chip you used? Thanks

@rdeveloper It's the Byonics Pocket Tracker. It's no longer available, but there are a few problems with this design. It doesn't have receive sense, which means the transmission can clobber other people on frequency trying to send their positions.

how much is the range on this device?

[rdeveloper]

would u show us the schematics and the software too? please!

TIA

What is the range for these? How much do they cost to build? Neal
