Why Russia Built Its Own GPS Instead of Using America's

GPS is free. So why did Russia, Europe, and China each spend billions building their own?

Your phone finds you from satellites overhead — but there are four separate systems, not one. They exist for one reason: control.

GPS is run by the US military — that's the whole problem. From 1990 to 2000, Selective Availability scrambled the civilian signal to 100 metres, while the military kept precision. It's off now — even removed from new satellites — but the US still controls GPS, and can deny it region by region. Russia built GLONASS in the Cold War — 24 satellites beyond Washington's reach. China built BeiDou — 35 satellites, accurate to a few metres publicly, 10 centimetres for its military. And Europe built Galileo: independence from a system it doesn't control.

Here's the twist: your phone is probably using all four right now — without you knowing. Modern chips don't pick one. They trilaterate from whatever's overhead, blending American, Russian, European, and Chinese signals together. The rivalry that cost billions? Your phone settled it in firmware.
