It is a global navigation satellite system that provides geolocation and time information to a GPS receiver anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites . </P> <P> The GPS does not require the user to transmit any data, and it operates independently of any telephonic or internet reception, though these technologies can enhance the usefulness of the GPS positioning information . The GPS provides critical positioning capabilities to military, civil, and commercial users around the world . The United States government created the system, maintains it, and makes it freely accessible to anyone with a GPS receiver . </P>
