In order for a satellite to successfully orbit the Earth, it must travel a horizontal distance of 8000 meters before falling a vertical distance of 5 meters. A horizontally launched projectile falls a vertical distance of 5 meters in its first second of motion.
1 Medium-Earth orbits (MEO) â These satellites park in between the low and high flyers, so from about 1,243 miles (2,000 kilometers) to 22,223 miles (36,000 kilometers). 2  Navigation satellites, like the kind used by your car's GPS, work well at this altitude. Satellites moving close to the Earth's surface are ideal for making observations, for military purposes and for collecting weather data. 2  Medium-Earth orbits (MEO) â These satellites park in between the low and high flyers, so from about 1,243 miles (2,000 kilometers) to 22,223 miles (36,000 kilometers).
