What happens if geodesy disappears? Phones, planes, and warning systems would fail. Our cartoon “Lost Without Geodesy” shows how vital this invisible science is. Geodesy powers GNSS, enabling precise positioning, earthquake monitoring, sea level studies, and more. Without it, GNSS would drift and global systems would collapse.
