Geo-stationary geostationary satellites: These types of geostationary satellites are placed 22,000 mls above the equator. These satellites comprehensive one revolution around the world in Twenty four hours and stay in fixed area above the world's surface. An individual geo-stationary satellite handles 40 percent associated with earth's location, whereas some satellites must cover the complete surface of the world.
Low-earth-orbit satellites: Most of these satellites are positioned a few 100 miles above the earth with a stationary height. They comprehensive one revolution around the world within 90 minutes. The conversation system is organized in a way that one or more satellite is in line of sight at any given time at any specific point on the earth.
Satellite television orbiting inside Elliptical design: These types of geostationary satellites move quickly around the world when they are put at a reduce altitude, but move slowly whenever placed with a higher height.
Limitations associated with Satellite Mobile phones:Satellite mobile phones work well provided that there is a apparent line of eye-sight between the skies and its aerial.
