Why GPS Alone Is Not Enough Anymore? (Multi-Constellation / Multi-Frequency Navigation)

When GPS was born in the 1980s, it revolutionized navigation. 24 satellites, synchronized atomic clocks, and a promise: global positioning for everyone.

But the world didn’t stop evolving. Cities grew taller. Signals reflected and vanished.

As precision became essential for drones, autonomous cars, and scientific measurements, one system was no longer sufficient.

Today, modern navigation depends not just on GPS, but on a constellation of constellations.
