GPS signal
Orbiting location data
A GPS signal is the radio transmission from satellites in the Global Positioning System, used by receivers to calculate precise location.
The signals carry timing and orbital data that allow devices to determine position through triangulation.
Signal quality varies—buildings, trees, and weather can weaken or block it: I lost GPS signal in the parking garage, waiting for GPS signal to lock.
