GPS

GPS transforms daily life by enabling precise real-time positioning anywhere on Earth, evolving from a Cold War military project into critical infrastructure for logistics, ride-sharing, and precision agriculture. Over 6 billion GPS receivers are in use globally as of 2023, supporting 20% of the world's economy. It outperforms #2 (the internet) in enabling location-specific services, as without GPS, ridesharing or delivery apps would lack the spatial accuracy to function. GPS data streams offer up to 30 cm accuracy with advanced corrections, outpacing the average navigation system's 5-meter baseline, making it indispensable for autonomous vehicles and emergency response.
