who created the gps

Short answer: No single person “created” GPS. It was developed by the U.S. Department of Defense in the 1960s–70s, with key contributions from Roger L. Easton, Ivan Getting, and Bradford Parkinson, who are often called the “fathers of GPS.”

Who actually created GPS?

When people ask “who created the GPS,” they’re usually referring to the modern satellite-based Global Positioning System used in phones, cars, planes, and ships today.

This system grew out of several military navigation projects that the U.S. Department of Defense merged into one program in the early 1970s, later named NAVSTAR GPS.

The three most credited figures are:

• Roger L. Easton – Led Navy research on satellite tracking and time-based navigation (TIMATION), and is listed on a key early GPS patent.

• Ivan Getting – Aerospace engineer who pushed for a precise satellite navigation system and helped shape the 621B concept for space-based positioning.

• Bradford Parkinson – First program manager of NAVSTAR GPS, widely known as the “Father of GPS” for architecting and leading the system into reality.

In many official and military histories, you’ll see all three referred to as the “fathers of GPS” , reflecting that it was a team invention, not a solo breakthrough.

Mini timeline: how GPS came together

• 1960s – Early satellite navigation systems
  • The U.S. Navy develops Transit and later TIMATION, using satellites and precise timing to locate submarines.

* Roger Easton’s TIMATION introduces key ideas: high‑precision space clocks and time‑based navigation, which are core to GPS today.

• Early 1960s–early 1970s – Concepts and studies
  • Air Force and Aerospace Corporation explore the 621B satellite navigation concept, with Ivan Getting championing the idea of accurate “lighthouses in the sky.”

* These studies show that a constellation of satellites could provide continuous, global coverage.

• 1973 – Official birth of GPS
  • U.S. Department of Defense merges Navy, Air Force, and Army ideas into the Defense Navigation Satellite System, soon renamed NAVSTAR GPS.

* Bradford Parkinson takes charge as the first GPS program manager and system architect.

• Late 1970s–1980s – Satellites and testing
  • First experimental GPS (Navstar) satellites launch in 1978 to validate accuracy and reliability.

* The constellation grows, and the system gradually becomes usable for military navigation.

• 1990s – GPS goes fully operational
  • By the early 1990s, a full constellation (about 24 satellites) is in orbit, and GPS becomes fully operational for global positioning.

* Over time, access broadens and it becomes a civilian tool used in cars, smartphones, agriculture, aviation, and more.

Why it’s hard to name just one “inventor”

• Multiple core technologies
  • Atomic clocks in space (TIMATION and Navy work).

* Satellite constellation architecture (Air Force 621B concept).

* System integration and signal design (NAVSTAR GPS Joint Program Office under Parkinson).

• Different titles, different credits
  • Roger Easton is often called a principal inventor; he holds an early GPS‑related patent and introduced crucial time-based navigation concepts.

* Bradford Parkinson is frequently labeled the “Father of GPS” for leading the program and architecting the operational system.

* Ivan Getting is honored as a co‑father for his vision and leadership in satellite navigation through The Aerospace Corporation.

Because of this, many modern write‑ups say something like: “GPS was created by the U.S. Department of Defense, with key inventors Roger L. Easton, Ivan Getting, and Bradford Parkinson.”
