GPS Ground Stations

GPS ground stations are large, highly accurate reference points located around the world. They monitor and track the signals transmitted by GPS satellites, ensuring these signals are precise and synchronized. These stations collect data on satellite positions and clock accuracy, then send corrections to improve GPS receiver accuracy on the ground. Think of them as the 'ground control' that keeps GPS systems reliable, accurate, and working seamlessly for navigation, mapping, and timing applications. Without ground stations, GPS signals would drift, reducing the precision necessary for many critical activities.
