 The father of GPS technology, Roger Lee Easton, died at the age of 93 May 8th. Easton was a visionary, inventor and pioneer of modern-day navigation. He spent 37 years in Washington D.C. as a physicist at the U.S. Naval Research Laboratory and developed a system that put highly accurate clocks in multiple satellites and could be used to determine the precise location of someone on the ground. He called it timeation for time navigation. Easton's vision led to the U.S. First Satellite Tracking Network became what we know today as the Global Position System, or GPS. Today, GPS is a constellation of Earth-orbiting satellites providing precise navigation and timing data to military and civilian users worldwide.
