Cheap Vehicle GPS Tracker for Off-Road GPS Navigation
The Global Positioning System (GPS) is a navigation system designed and developed by United States Air Force. It is a network of 24 space-bound satellites controlled and monitored by United States Department of Defence. These satellites transmit signals to the surface all year round. GPS devices such as cheap vehicle GPS trackers receive these signals and compute the same information to calculate the exact location of the user.
