概要
Every time you open Google Maps, you’re relying on 31 satellites, atomic clocks accurate to one second every 300 million years, and a relativistic correction Albert Einstein made possible in 1915.
Most people use GPS dozens of times a day and have no idea how it actually works. In this episode of The Static Frontier, we break down the real mechanism — from satellites and signal timing to why the word “triangulation” is wrong, and why GPS would be 6 miles off within a day if we didn’t correct for Einstein’s theory of general relativity.
🔍 WHAT YOU’LL LEARN:
• How GPS calculates your position using signal travel time — not angles
• Why trilateration is different from triangulation (and why it matters)
• How atomic clocks work and why they’re accurate to 1 second per 300 million years
• Why Einstein’s relativity theories are baked into every GPS calculation
• How your phone blends satellites, cell towers, and Wi-Fi to track you indoors
• Why a GPS outage would crash financial markets, power grids, and air traffic control
