There are hundreds of civvy applications that are GPS enabled, and millions of them sold every year... it always strikes me as odd that Garmin et al do not have to pay a percentage of each sale of a GPS enabled unit to the budget holders responsible for the upkeep of the sat system.
It wouldn't have to be much, maybe 1 or 2 % of each unit sale, but it would go a long way to funding what is in actual fact, a military application that civilians have been granted use of.
