Idea of how GPS tracking works is quite simple. A GPS tracking device works by communicating with satellites that orbit around the planet. These satellites are owned by the United States Department of Defense that were opened for civilian use since 1996. These 24 satellites are responsible for feeding the exact location on to the tracking device.
The signals they transmit are very accurate because they all work simultaneously. Apart from the location, they can also give data that will show the tracking device’s speed, altitude, and direction.
Truly, the technology of GPS has come a long way. Now, we see them on mobile phones and in the internet.
