Roger Lee Easton, Sr. (April 30, 1921 – May 8, 2014) was an American physicist and state representative

Ivan A. Getting and Bradford Parkinson.[2]

Career

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

Sputnik I was launched, Easton extended the system to actively follow unknown orbiting satellites.[2]

In 1959, he designed the Naval Space Surveillance (NAVSPASUR) system. The

Naval Space Surveillance System became the first system to detect and track all types of Earth-orbiting objects. It goes through the 33rd parallel, which is effectively coast to coast of the US.[2]

Later in his career at NRL, Easton conceived, patented, and led the development of essential enabling technologies for the United States Global Positioning System (GPS). During the 1960s and early 1970s he developed a time-based navigational system with passive ranging, circular orbits, and space-borne high precision clocks placed in satellites. The idea was tested with four experimental satellites: TIMATION I and II (in 1967 and 1969) and Navigation Technology Satellites (NTS) 1 and 2 (in 1974 and 1977). NTS-2 was the first satellite to transmit GPS signals.[2]

Personal life

Easton was born on April 30, 1921, in

Naval Research Laboratory in 1943.[6] At the Naval Research Laboratory he worked in the Radio Division on radar beacons and blind-landing systems. Easton also worked in the laboratory's Rocket-Sonde Branch which was dealing with space related research.[2]

Easton retired in 1980.[5] In 1986, Easton ran for Governor and served three terms on the Board of the New Hampshire Electric Cooperative.[7]

Easton died on May 8, 2014, at the age of 93.[4]

Awards

Easton was elected to

National Medal of Technology is the highest honor awarded for technology.[7]

On March 31, 2010, Easton was inducted into the

TIMATION – U.S. Patent 3,789,409) that provided both accurate position and precise time to terrestrial based observers, an important foundation for contemporary Global Positioning Systems.[11]

During his career at the Naval Research Laboratory, Easton was awarded:[7]

  • The Distinguished Civilian Service Award (1960)
  • The Institute of Navigation's Colonel Thomas L. Thurlow Navigation Award (1978)
  • The Naval Space Surveillance Center established the Roger L. Easton Science and Engineering Award (1991)
  • Inducted into the GPS Hall of Fame (1996)
  • Magellanic Premium (1997)
  • 12th Sheikh Salam Al-Ali Al-Sabah Informatics Badge of Honour from His Highness, the Amir of Kuwait, for Easton's role as the "Prime Inventor of GPS" (2013)[12]
