The Global Positioning System (GPS), originally Navstar GPS,[2] is a satellite-based radio navigation system owned by
the United States government and operated by
the United States Space Force.[3] It is one
of the global navigation satellite systems (GNSS) 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.[4] It does not require
the user to transmit any data, and operates independently
of any telephonic or Internet reception, though these technologies
can enhance
the usefulness
of the GPS positioning information. It provides critical positioning capabilities to military, civil, and commercial users around
the world. Although
the United States government created, controls and maintains
the GPS system, it is freely accessible to anyone with a
GPS receiver.[5]
