GPS signal

A GPS signal is a radio wave transmitted by satellites orbiting Earth. These signals contain precise timing and location information. When a GPS receiver on the ground picks up signals from multiple satellites, it calculates how far away each one is based on the signal's travel time. Using this data, the receiver determines your exact position by triangulating the distances. This system allows devices, like smartphones or navigation units, to provide accurate location, directions, and timing information for various applications worldwide.
