This post deals with a gps tracker you ring and it sends back its coordinates
I don't want to ring it to get GPS data
I want to operate it all from a battery and store wherabouts to an SD card every hour or three. No GSM required. I want to track my car /truck and where it goes Only want to store the Date/Time, Location & Speed
Anybody done this or planning to or any other leads to save reinventing the wheel ?
