I would like to make my own gps tracker, Im used to using pic related, but the distance it can reach is max 2km in the forrest, and i need more distance, I thaugt about i could make something like tracking a phone? over gps? anyone got any ideas?
after 2km or so i loose signal to the dog, i must go in the car and search the dog, if i come around 2km near him i get his signal again.
it is the same with the gps from my friends
also i use the older model too
You have two options.
1) Up your transmission power, increase your antenna size. I'd play with the antenna before trying to amplify, for obvious reasons.
2) buy a tracker that interfaces with the cellular network. This requires a SIM card and a contract. Here is one model from the dozens sold on amazon.
>Acquire a phone that works with one of the cell providers that offer free monthly service, the smaller the better
>Acquire otterbox or other waterproof case for phone
>Attach to dog collar/girlfriend's car
>Use tracking app to track dog/cheating girlfriend
