The Global Positioning System (GPS), originally Navstar GPS, [2] is a satellite-based radio navigation system owned by the United States Space Force and operated by Mission Delta 31. [ 3 ] [ 4 ] 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 ...
The Naval Research Laboratory’s managers for the Timation program and, later, the GPS program: Roger L. Easton (left) and Al Bartholomew. In 1955, Easton co-wrote the Naval Research Laboratory's Project Vanguard proposal for a U.S. satellite program in competition with two other proposals, including a proposal from the U.S. Army prepared by Wernher Von Braun.
Gladys Mae West (née Brown; born October 27, 1930 [1]) is an American mathematician.She is known for her contributions to mathematical modeling of the shape of the Earth, and her work on the development of satellite geodesy models, that were later incorporated into the Global Positioning System (GPS).

The United States' Global Positioning System (GPS) consists of up to 32 medium Earth orbit satellites in six different orbital planes. The exact number of satellites varies as older satellites are retired and replaced. Operational since 1978 and globally available since 1994, GPS is the world's most utilized satellite navigation system.
Vehicle navigation on a personal navigation assistant Garmin eTrex10 edition handheld. A satellite navigation device or satnav device, also known as a satellite navigation receiver or satnav receiver or simply a GPS device, is a user equipment that uses satellites of the Global Positioning System (GPS) or similar global navigation satellite systems (GNSS).
Ivan Alexander Getting (January 18, 1912 – October 11, 2003) was an American physicist and electrical engineer, credited (along with Roger L. Easton and Bradford Parkinson) with the development of the Global Positioning System (GPS).
The Boston Globe reports researchers found that becoming overly reliant on GPS might be bad for our minds because generating mental maps plays a role in other daily activities.
Bradford Parkinson (born February 16, 1935) is an American engineer and inventor, retired United States Air Force Colonel and Emeritus Professor at Stanford University.He is best known as the lead architect, advocate and developer, with early contributions from Ivan Getting and Roger Easton, of the Air Force NAVSTAR program, better known as Global Positioning System.
