GPS Failure in China Causes Widespread Disruption

Imagine you're in a big city, and suddenly your phone can't tell you where you are.

That's what happened in Nanjing, China.

For six hours, people couldn't use their car navigation, order rides, or get food delivered because the GPS and another system called BeiDou stopped working.

Some people even got lost in places they knew well.

Experts think something might have interfered with the satellite signals, but they're not sure what.

This shows how important these systems are and how much trouble we could have if they stop working.

India uses similar systems, so this is a reminder to be prepared for such problems.
