Hi. I have several dogs that we let run on our 10 acre property. I would like to make a harness with a module containing a GPS and method to store the output for the GPS on a SD card. I would then be able to download the date from the GPS stored on the SD card to my computer to analyze where they have been hanging out.
Does anyone know how to do this. It needs to be rugged and small. It should also run a long time on small batteries.
