Bradford Parkinson, professor of aeronautics and astronautics at Stanford University, conceived the present satellite-based system in the early 1960s and developed it in conjunction with the U.S. Air Force.
Transit
The first satellite navigation system was Transit, a system deployed by the US military in the 1960s. Transit’s operation was based on the Doppler effect: the satellites travelled on well-known paths and broadcast their signals on a well-known radio frequency.
Embracing previous ideas from Navy scientists, the DoD decided to use satellites to support their proposed navigation system. DoD then followed through and launched its first Navigation System with Timing and Ranging (NAVSTAR) satellite in 1978. The 24 satellite system became fully operational in 1993.
What is a group of satellites used for navigation?
Collectively, these constellations and their augmentations are called Global Navigation Satellite Systems (GNSS). The receiver uses the time difference between the time of signal reception and the broadcast time to compute the distance, or range, from the receiver to the satellite.
What was the first navigation system?
The first truly automotive navigation system was developed almost forty years ago by Honda, Alpine and Stanley Electric and it was called the Electro Gyro-Cator.
Nathaniel Bowditch is a famed, reputed and illustrious name in the maritime industry. The self-made nautical expert paved the way for the future of the global maritime navigational elements over 200-years ago and is considered the founder of Modern Maritime Navigation.
Is Galileo global?
Galileo is Europe’s own global navigation satellite system, providing a highly accurate, guaranteed global positioning service under civilian control. Currently providing Initial Services, Galileo is interoperable with GPS and Glonass, the US and Russian global satellite navigation systems.

With time, GPS was opened up for public use. Currently, GPS has a 33 satellite constellation, out of which 31 are in orbit and operational. It is maintained by the US Air Force and is committed to maintaining the availability of at least 24 operational GPS satellites. Till date, GPS has launched 72 satellites.
Who is the first navigation?
The first Western civilization known to have developed the art of navigation at sea were the Phoenicians, about 4,000 years ago (c. 2000 B.C.E. ). Phoenician sailors accomplished navigation by using primitive charts and observations of the Sun and stars to determine directions.
What did Henry the Navigator discover?
After procuring the new caravel ship, Henry was responsible for the early development of Portuguese exploration and maritime trade with other continents through the systematic exploration of Western Africa, the islands of the Atlantic Ocean, and the search for new routes.
