Why GPS Doesn’t Work in Nuclear Submarines

Unlike planes, ships, and cars, these deep-diving giants can’t rely on satellite signals! GPS works by connecting to orbiting satellites, but water-especially deep ocean water-completely blocks these signals.
Without GPS, how do submarines navigate? They use Inertial Navigation Systems (INS), which track movement through gyroscopes and accelerometers-no satellites needed! But there’s a catch: INS drifts over time, meaning submarines must occasionally surface to recalibrate their position.
These high-tech subs might be invisible beneath the waves, but their navigation is a masterpiece of engineering! Next time a nuclear sub disappears underwater, remember-it’s navigating in the dark… with extreme precision!
