How GPS Left Government Hands and Changed Everything

On September 1, 1983, Korean Air Lines Flight 007 was shot down by Soviet fighters after straying into Soviet airspace — killed by a navigation error. Two weeks later, President Reagan announced that the US would make GPS available for civilian use once the system was operational.

A technology built to guide nuclear warheads would become the infrastructure for food delivery apps.

What the government built

The Global Positioning System was a Department of Defense project, fully funded by the US military, designed to provide precise positioning for military assets. The satellites were launched from 1978 onward. Full operational capability was declared in 1995.

Because it was government-funded and operated, the core GPS signal was never patented in a way that restricted civilian use. The government can't enforce patents against the public for technologies it funds. GPS technology was, from the start, available for anyone to build on.

The scramble for the edges

The core GPS signal was free. Everything built around it was fair game for patents.

The 1990s and 2000s saw an explosion of patent filings around GPS receiver technology, map databases, turn-by-turn navigation algorithms, and location-based services. Companies like Qualcomm, Nokia, and later Google built enormous patent portfolios around the civilian GPS ecosystem.

When smartphones integrated GPS chips in the late 2000s, every navigation app company was suddenly navigating patent minefields. The core technology was open. The implementations were locked up.

The database problem

Here Maps (formerly Nokia Maps, formerly Navteq) and TomTom (which acquired Tele Atlas) built the first comprehensive digital road databases. This wasn't patented — it was proprietary data. The maps themselves were trade secrets worth billions.

Google Maps, when it launched in 2005, initially licensed map data from these providers. The goal from the start was to build Google's own. Street View, launched in 2007, began generating Google's own geospatial data at scale. By 2012, Google had largely replaced licensed map data with its own.

The competition was ultimately about data, not patents. You can patent an algorithm for routing. You can't patent the fact that a particular road exists.

What free GPS built

The decision to make GPS freely available is one of the most consequential infrastructure decisions in modern history:

• Ride-sharing (Uber, Lyft) depends entirely on real-time positioning
• Modern logistics and supply chain management runs on GPS tracking
• Agricultural precision farming uses differential GPS for centimeter accuracy
• Aviation safety systems layer on GPS positioning

The economic value created runs into trillions of dollars. The original investment — a Cold War military program — cost roughly $12 billion.

The lesson isn't that all technology should be public. It's that infrastructure-level technologies often generate more value when left open than when enclosed. The patents that got built on top of GPS created enormous value too — they just didn't lock down the foundation.
