GPS was originally developed by the U.S. Department of War during the Cold War to provide precise positioning, navigation and timing for military operations. Early systems were designed primarily to support warfighters, aircraft, ships and missile guidance with highly accurate location data anywhere on Earth.
Over time, however, GPS expanded far beyond military applications. What began as a national defense capability quietly became one of the invisible foundations of modern daily life.
Today, GPS helps power navigation apps, emergency response systems, aviation, agriculture, financial networks, shipping logistics and global commerce. Billions of people rely on GPS every day, often without even thinking about where the signals originate or how much infrastructure is required to keep the system functioning.
Entire industries now depend on ultra-precise timing and positioning data transmitted continuously from satellites orbiting thousands of miles above Earth.
Why that’s honestly kind of wild: A military navigation system became one of the invisible foundations of modern civilization.
Behind the scenes, GPS requires enormous technical infrastructure maintenance, and L3Harris has supported that mission from the very beginning. The company’s technologies were part of the first GPS satellites launched in 1978, including code generators and transmitters. Since then, L3Harris payloads and components have flown on every U.S. GPS satellite across more than 70 missions. Through those contributions, L3Harris has helped make GPS technology more accurate, resilient and dependable for users around the world.
At the same time, L3Harris is transforming position, navigation and timing (PNT) to meet 21st-century warfighter needs with experimental programs such as NTS-3. As the only company supporting GPS across the entire enterprise—from spacecraft and payloads to ground systems, user equipment and modernization efforts—L3Harris is demonstrating what is possible for the next generation of space‑based PNT. As jamming and spoofing threats continue to evolve, L3Harris navigation and anti-jam solutions help provide the resilience, security and reliability needed to maintain mission effectiveness when GPS is challenged.
