Mr. Easton was born on 30th April 1921 in Vermont province Nord Crafts Berry. Mr. Easton graduated from a local high school to Middlebury University and graduated from the same school in 1943 will continue to Michigan University, but it will be in Washington, DC shortly thereafterThe U.S. Naval Research Laboratory (NRL)He took the position of a physicist, and built a career of 37 years since then.

In 1955, the international scientific research project started later in 1957International Earth Observation YearFor the launch of the observational satellite used in the US military led developmentVanguard ProjectWe will be in charge of part of the proposal, and will also be engaged as a member of the satellite design team. Here we track the satellite's flight such as Soviet's 'Sputnik' flying in space, American 'Vanguard', 'Explorer'Minitrack NetworkI was also involved in the design of.

This Minitrack network had problems with accurate time synchronization among multiple tracking stations that grasp the position of the satellite from the ground. In order to solve this, we built a system to accurately grasp the mutual positional relation by synchronizing the timing by loading accurate clock on each satellite. This systemTimation(Coined word from Time-Navigation), later handled by the US Department of Defense, in the early 1970's "Global Positioning System(GPS) "to be called.

Mr. Easton's patents acquired with the Timation system are "Navigation Systems Using Satellites and Passive Ranging Techniques" (US Patent 3,789,409), which is a navigation system using satellite and passive ranging technology. Although it is very simple on the front cover, the concept of positioning the position of the ship on the earth using satellites is drawn.

Mr. Easton has acquired 11 patents including those related to this Timation system, and from that technology, "1970"Thomas L. Thurlow AwardAwarded. In 1993 it was awarded to companies and individuals who showed outstanding achievements in the American aviation industryKorea - Trophy"Was awarded as a member of the GPS research team, and in 1998"American Philosophical Society(American Philosophical Society) ", and in 2004American National Technology Award, In 2010National Inventors Hall of Fame(Hall of Fame of the US inventor) also entered the Hall of Fame and has many honors.

In 1980 he retired from the US Naval Research Institute, who served as head of the Space Applicaton division, moved to Canaan, New Hampshire. Again continued to contribute to the development of GPS technology. In addition, he enrolled in the New Hampshire Assembly for the second term, in 1986 it became a primary election for the mayor's jobSeabrook Nuclear Power StationI ran out from the opposition faction and sometimes lost.

In general society, there are many people who start with car navigation system (car navigation system), GPS systems that are now within small smart phones are indispensable for daily living, and even though they are invisible to other people, they are greatly involved in society Mr. Easton's contribution to the development of a GPS system has become very big.
