Why Do Satellites Have Different Orbits? - SciJinks

Web28 mrt. 2014 · Communications satellites relay signals from a fixed spot on the equator, about 22,000 miles up. GPS satellites are at 12,400 miles, high enough to be accessible to large swaths of the Earth. The mean orbital velocity needed to maintain a stable low Earth orbit is about 7.8 km/s (4.8 mi/s), which translates to 28,000 km/h (17,000 mph). However, this depends on the exact altitude of the orbit. Calculated for a circular orbit of 200 km (120 mi) the orbital velocity is 7.79 km/s (4.84 mi/s), but for a higher 1,500 km (930 mi) orbit the velocity is reduced to 7.12 km/s (4.42 mi/s). The launch vehicle's delta-v needed to achieve low Earth orbit starts around 9.4 km/s (5.8 mi/s). Web7 nov. 2024 · The Hubble Space Telescope and the International Space Station (ISS) orbit Earth in the thermosphere. Even though the thermosphere is the second-highest layer of Earth’s atmosphere, satellites that operate here are in “ low-Earth orbit.” Exosphere The fluctuating area between the thermosphere and the exosphere is called the turbopause. optical fork sensors
