Can anyone tell me how accurate, in general, the speed (mph) is?
This system is for keeping tabs on teenagers, and if they break the speed limit, according to Accutracking, it has to be reasonably close or I can not call them on it. I realize altitude can be way off, and location can be within hundreds of feet, but speed has to be more accurate. Also, how is speed measured? Is it simply distance between GPS fixes measured over the time period?
