On April 13, 1960, the United States launched Transit 1B, the world’s first satellite navigation system! Before GPS, navigation depended on maps and radio signals, but the U.S. Navy needed more precise positioning for its submarines. Transit 1B changed the game, using satellite signals to provide real-time location tracking. Developed by Johns Hopkins Applied Physics Lab, this technology laid the foundation for the modern GPS we use today—for driving, deliveries, and tracking lost phones!
