Fundamentally, it would be impossible to tax GPS. The satellites are broadcasting their signal openly so that anybody with a reciever, a computer, and the relavant equations can use it. Trying to filter out those that paid and those that didn’t is basically impossible so instead the US government pays for the system as a public service.
