Easton *** Lifespan of Inventor: 1921 - 2014 *** Nationality of Inventor: American *** Historical Period: Technology and Information Age *** Category: Communications and Information *** Country of Origin: America *** Facts about the Inventor, Roger L. Easton, and the invention of GPS ***
Fact 1: Who invented GPS? The GPS was invented by Roger L. Easton in 1974 during the Technology and Information Age of inventions.
Fact 2: Who invented GPS? Prior to the invention of GPS the Compass was the only navigational instrument. Paper maps and a few route finders were then used to guide us to our destinations.
Fact 3: Who invented GPS? The invention of Smartphones, Mobile Apps and GPS devices now help us navigate to different locations with the assistance of voice guided directions with real time navigation and maps.
Fact 4: Who invented GPS? The inventor of GPS, Roger L. Easton, was born on April 30, 1921 in Craftsbury, Vermont, United States and died on May 8, 2014. His invention of a Global Positioning System (GPS) required the development of sophisticated technology and various satellite launches before GPS could become a reality.
Fact 5: Who invented GPS? The early years of Roger L. Easton were spent in Craftsbury, Vermont, United States where he was raised by his family. His father was Frank Birch Easton, Sr. and his mother was Della (Donnocker) Easton. Roger L. Easton was educated at Middlebury College and the University of Michigan.
Fact 6: Who invented GPS? Following his education his first, and only, job was as a physicist at the U.S. Naval Research Laboratory in Washington, DC. During the later part of WW2 (1939 - 1945) he served in the U.S. Navy working on radar beacons and blind-landing radio navigation systems.
Fact 7: Who invented GPS? During the 1950's Roger L. Easton became involved in early rocket experiments just before he joined a satellite design team.
Fact 8: Who invented GPS? Roger L. Easton then moved on to work on tracking satellites and designed the Minitrack Network that was used to track Sputnik I and Sputnik 2, the world's first artificial satellites that were developed by the Russians during the Cold War era and the the US satellites Explorer and Vanguard.
Fact 9: Who invented GPS? In the mid 1960's Roger L. Easton then went on to test his concepts of time-navigation at the Naval Research Laboratory's (NRL) Naval Center for Space Technology (NCST).
Fact 10: Who invented GPS? The project was dubbed TIMATION (TIMe/navigATION), a space and time based navigation system technology program that advanced the development of the stability of clocks and time precision), time-transfer, and two-dimensional navigation.
Fact 11: Who invented GPS? The First Timation satellite was launched in 1967. TIMATION project led to the invention of the atomic clock for satellite navigation and the birth of satellite navigation and the Global Positioning System (GPS).
Fact 12: Who invented GPS? The satellites named TIMATION I and II were launched in 1967 and 1969 and the US Department of Defense selected various features of the Timation technology and the new system was renamed the Global Positioning System, or GPS.
Fact 13: Who invented GPS? Roger L. Easton was granted eleven U.S. patents, including the 1974 patent number 3,789,409 for "Navigation Systems Using Satellites and Passive Ranging Techniques".
Fact 14: The Navigation Technology Satellites, NTS 1 and NTS 2, were launched in 1974 and 1977 respectively. NTS-2 was the first satellite to transmit GPS signals.
Fact 15: The development of GPS included a launch programme of 10 satellites from 1978 - 1994 known as Block I satellites. Improved Block II satellites were then developed consisting of a further 28 satellites.
Fact 16: In December 1990, the Navstar system became operational.
Fact 17: In 1983 President Ronald Reagan ordered that GPS should be made freely available for civilian use once it was sufficiently developed.
Fact 18: Roger L. Easton died on May 8, 2014 at his home in New Hampshire at the age of 93 years old.
Fact 19: Google Maps, a web mapping service developed by Google in 2005 took the Global Positioning System (GPS) to the next level providing satellite imagery with street maps, real-time traffic conditions and route planning.
Who invented GPS? We hope that the facts in this article have provided the answers to all of your questions about the invention of the Global Positioning System (GPS) and its famous inventor, Roger L. Easton.
