... the atmosphere, so there is very little resistance to their motion. They are launched into orbit horizontally at speeds of at least 17,500 miles per hour (mph) but remain under ... of atmosphere which will eventually cause a satellite's orbit to drop lower. Beyond this low orbit regime, a satellite can remain in orbit forever.

... paper in Wireless World. Less well-known is where the credit for discovering the Molniya orbit should lie. This paper presents the evidence uncovered to date concerning the original concept and provides some insight into the ways in which the orbit has subsequently been exploited.

... hybrid direct-indirect optimization algorithm is presented to compute the minimum-time transfer between two orbits, including the phasing with a desired spacecraft. Very-low thrust means several hundred revolutions to perform the large change in orbital elements. The optimal control solution of the fast-evolution problem combined with a direct method ...
... propulsion system or thrusters on board that would be used to maintain their position in orbit. The thrusters would only be used occasionally to maintain correct position because the module would be orbiting around Earth and the gravitational pull would keep it in place. At first, the modules ...
We need to go about 17,000 miles per hour to orbit and to maintain a space orbit. There is a range of speeds at which the different satellites travel. Because of ... in space we are. So if we want to put a satellite in a different orbit, we make sure that it has different speeds and orientation from those of the other ...
... provide the short up and down (sub-orbital) trips. Also, people have started to design spaceships for orbital tourism trips, and other people are designing the orbital hotels. Much later, there will be ...
... ) are very stable, and it takes months to years for a spacecraft in LEO orbit to decay and re-enter. It is an unlikely situation. The Shuttle and ISS have the ability to perform re-boosts and corrective burns to keep them on orbit and on course.

- 05. Where in space do satellites orbit? Do their signals interfere with each other? (A K2S Question)
Communications and TV-broadcasting satellites generally orbit at 22,300 miles, which is called the geostationary orbit. This is because at this altitude, the satellites take exactly a day to get around ... ;because, meanwhile, the Earth spins around once a day too Other kinds of satellites can orbit as low as about 150 miles, and others operate at intermediate altitudes. An organization in ...
There are nearly 6,000 satellites in orbit. Around ten countries have launched satellites, but often a country will have a satellite launched on someone else's rocket. There are about 20 countries with satellites in orbit.
