I need a GPS unit for a personal project. I don't need anything fancy, just a grid coordinate, and direction. Needs a high refresh rate, and most of all, I need some way of getting that data out of the GPS so I can play with it and do stuff with it.\n\nultimate goal, is to beam said coordinates via radio transmitter... for science.\n\nPlayed around with the idea of a localized Radio based GPS... R-LTS. But before I embark on that journey I thought i wise to check whats already on the market to see if a solution already exists.\n\nAny suggestions for a bare bones GPS with an output? Dare I ask, maybe a USB output :D?\n\nExtra points if it can give elevation, and/or work indoors.
