GPS

What is GPS and how does it work?

GPS, Global Positioning System, is a satellite navigation system that enables precise positioning anywhere on Earth. It works by receiving signals from at least four satellites orbiting the planet, which transmit time data. The receiver then calculates the distance from each satellite and determines the exact position. The system was developed by the U.S. Department of Defense in the 1970s, became fully operational in 1995, and has been fully available for civilian use since 2000.

Is GPS patented?

The concept of GPS as a system is not a typical commercial patent, but a government military project of the United States. However, individual technologies, receivers, and navigation devices may be patented. Today, GPS is complemented by other global systems such as the Russian GLONASS, European Galileo, or Chinese BeiDou, which improve signal accuracy and availability.

Use of GPS in the military

For armed forces, GPS is a key navigation and tactical tool. It is used for precise positioning of units, guidance of equipment, coordination of formations, and fire control. Modern military systems use encrypted signals with higher accuracy and resistance to interference. GPS is now part of the equipment of soldiers, vehicles, drones, and guided munitions.

GPS in airsoft and MilSim events

In the airsoft environment, GPS is widely used in MilSim and tactical games. It serves for navigation in terrain, locating checkpoints, or completing scenario-based objectives. Modern game systems, such as PES, Player Evaluation System, use GPS to track player movement, evaluate mission progress, and enforce rules in real time. This pushes airsoft closer to realistic military simulations and gives organizers better control over the game. For players, GPS means better awareness, improved navigation, and a more immersive tactical experience.
