Final answer:
The motion of high-precision GPS networks is shown on maps through real-time tracking.
Step-by-step explanation:
The motion of high-precision GPS networks is shown on maps through real-time tracking.
A high-precision GPS network consists of satellites that emit signals to GPS receivers on the ground. These receivers then calculate their position based on the time it takes for the signals to reach them. This information is then displayed on a map, updating in real-time to show the current location.
