The Global Positioning System (GPS) is a satellite-based hyperbolic navigation system owned by the United States Space Force and operated by Mission Delta 31. It is one of the global navigation satellite systems (GNSS) that provide geolocation and time information to a GPS receiver anywhere on or near the Earth where signal quality permits. It does not require the user to transmit any data, and operates independently of any telephone 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 GPS, it is freely accessible to anyone with a GPS receiver.

Facts
YearInfobox gives the first GPS satellite's launch date (22 February 1978); the lead states GPS became fully operational only in 1993, a fact that appears in the article's History section rather than its lead or infobox, so this width-first pass records only the infobox launch date rather than half-guessing the operational date. SignificanceIt provides critical positioning capabilities to military, civil, and commercial users around the world. Although the United States government created, controls, and maintains GPS, it is freely accessible to anyone with a GPS receiver. 1 FAQs
Does a GPS receiver need a phone or internet connection to work?
No. A GPS receiver works independently of phone or internet reception, using only the signals broadcast from the GPS satellites.
A GPS receiver does not need to transmit any data of its own, and it operates independently of any telephone or internet reception. It works by receiving signals broadcast from the GPS satellites and calculating position and time from them. Phone and internet service can still make the positioning information more useful in practice, but neither is required for GPS itself to function.
