GPS did not come from NASA research. I should know since my Dad invented it.
Did your Dad invent the rocket to put a payload in a 10,000 mile high orbit?

No, but one his colleagues at NRL, Pete Wilhelm, devised innovates techniques to cheaply launch a satellite into 12 hour orbits.
[quote]He was awarded the National Medal of Technology for “his invention of the Minitrack satellite tracking system used to track Vanguard satellites and determine orbits; his development of the Naval Space Surveillance System still in use today cataloging all known man-made space objects orbiting Earth; his invention of a “Navigation System Using Satellites and Passive Ranging Techniques” and his subsequent development of Time Navigation and Navigation Technology Satellites that formed the technological basis for modern GPS.”
Easton conceived, patented, and led the development of critical enabling technologies for the United States Global Positioning System (GPS). GPS today is a constellation of Earth-orbiting satellites providing precise navigation and timing data to military and civilian users. Easton, as a scientist and engineer at NRL, developed his concept for a time-based navigational system with passive ranging, circular orbits, and space-borne high precision clocks synchronized to a master clock.[/quote]
