WebThe concept of geostationary satellite communications systems is generally credited to the futurist Arthur C. Clarke. Mr. Clarke wrote an article in 1945 stating that communications signals could be transmitted to and from Earth by a relay station launched into orbit at a distance of about 22,300 miles (36,000 kilometers) above the Earth’s equator.

Most of the artificial objects in outer space are in LEO, with an altitude never more than about one-third of the radius of Earth. The term LEO region is also used … See more A wide variety of sources define LEO in terms of altitude. The altitude of an object in an elliptic orbit can vary significantly along the orbit. Even for circular orbits, the altitude above ground can vary by as much as 30 km (19 mi) … See more 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 … See more The LEO environment is becoming congested with space debris because of the frequency of object launches. This has caused growing concern in recent years, since collisions at … See more 1. ^ Orbital periods and speeds are calculated using the relations 4π R = T GM and V R = GM, where R is the radius of orbit in metres; T is the orbital period in seconds; V is the orbital speed in m/s; G is the gravitational constant, approximately 6.673×10 Nm /kg ; M … See more A low Earth orbit requires the lowest amount of energy for satellite placement.
