You may be familiar with hibiscus, known as âsour teaâ in Iran, a delicious and refreshing summertime drink. Originally from Angola, hibiscus is now cultivated throughout tropical and subtropical regions, especially in Sudan, Egypt, Thailand, Mexico, and China.
High Earth Orbit. When a satellite reaches exactly 42,164 kilometers from the center of the Earth (about 36,000 kilometers from Earthâs surface), it enters a sort of âsweet spotâ in which its orbit matches Earthâs rotation.his special, high Earth orbit is called geosynchronous. A satellite in a circular geosynchronous orbit directly over the equator (eccentricity and inclination at zero) will have a geostationary orbit that does not move at all relative to the ground.
Like LEOs, these satellites donât maintain a stationary distance from the earth.This is in contrast to the geostationary orbit, where satellites are always approximately 22,300 miles from the earth. Typically the orbit of a medium earth orbit satellite is about 10,000 miles (16,093.44 km) above earth.In various patterns, these satellites make the trip around earth in anywhere from 2â12 hours, which provides better coverage to wider areas than that provided by LEOs.ow-Earth-orbiting satellites are less expensive to launch into orbit than geostationary satellites and, due to proximity to the ground, do not require as high signal strength (Recall that signal strength falls off as the square of the distance from the source, so the effect is dramatic) .
