Background

Global Positioning System (GPS) is a system of satellites in outer space that provide detailed information about the position and time of anyone on the Earth. The system is maintained by the United States Government. Anyone with a GPS receiver can track their location location to within XX using the GPS system.

Original civilian service for GPS devices was significantly downgraded. However, under Bill Clinton, civilians began to receive the most accurate GPS service available.

GPS may be accurate to within a few meters. However, accuracy varies on the quality of the receiving device. Some devices may be accurate to within a few centimeters.

As GPS technology has become more widely available, the price of GPS technology has fallen dramatically. Today, GPS can be found in the iPhone as well as inexpensive computerized navigation systems for cars.

Since GPS has the power to tell an individual exactly where a tracking device is at any given time the use of GPS devices has flourished as an investigatory device in many parts of the United States.

Local Courts are still grappling with whether the use of a GPS device over a long period of time violates a defendant's right to be free of warrantless searches and seizures.


GPS and the Fourth Amendment

Global Positioning System (GPS) is a space-based global navigation satellite system that provides reliable location and time information in all weather and at all times and anywhere on or near the Earth when and where there is an unobstructed line of sight to four or more GPS satellites. It is maintained by the United States government and is freely accessible by anyone with a GPS receiver.
