Roger Easton
Roger Lee Easton, Sr. (April 30, 1921 – May 8, 2014) was an American physicist and state representative who was the principal inventor and designer of the Global Positioning System, along with Ivan A. Getting and Bradford Parkinson. Career 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. The Eisenhower Administration selected Project Vanguard. In 1957, Easton invented the Minitrack tracking system to determine the Vanguard satellite's orbit. When Sputnik I was launched, Easton extended the system to actively follow unknown orbiting satellites. 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 ...

People Associated With The Global Positioning System
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of ...

Magellanic Premium
The Magellanic Premium, also known as the Magellanic Gold Medal and Magellanic Prize is awarded for major contributions in the field of navigation (whether by sea, air, or in space), astronomy, or natural philosophy. The Premium was established in 1786 through a grant by Jean-Hyacinthe Magellan ( pt, João Jacinto de Magalhães). Benjamin Franklin, then President of the American Philosophical Society, accepted it and established the terms of reference under which it would be given. In the 217 years since Magellan offered the Premium, the APS has awarded on only 36 occasions (as of 2021): twelve for navigation, twelve for natural philosophy, and eleven for astronomy.

TIMATION
The Timation satellites were conceived, developed, and launched by the United States Naval Research Laboratory in Washington, D.C. beginning in 1964. The concept of Timation was to broadcast an accurate time reference for use as a ranging signal to receivers on the ground. On 31 May 1967, the Timation-1 satellite was launched. This was followed by the Timation-2 satellite launch in 1969. The results of this program and Air Force Project 621B formed the basis for the Global Positioning System (GPS). The Navy's contribution to the GPS program continued to be focused on ever more accurate clocks. History There is a historical connection between accurate time keeping, navigation, and the Navy. In 1714, the British government passed the ''Longitude Act'' (see longitude prize) to create an incentive to solve the problem of navigation at sea. The solution, developed by John Harrison, was an accurate clock which could compare local time to Greenwich, England time. To this day, Coordin ...
