1.静止轨道和静止卫星在地球赤道平面上空35800 km圆形轨道上的卫星,其绕地球转动的周期与地球自转周期相同,从地球上看卫星是静止不动的,故称为静止卫星(也称同步卫星),称这样的运行的轨道为静止轨道或赤道同步轨道。典型的静止卫星轨道,近似圆形,远地点距离是35900 km,近地点距离是35885 km。 1. Geostationary Orbit and Geostationary Satellites 35,800 km above the Earth’s Equatorial Plane Orbiting on a circular orbit, the orbiting earth rotates at the same cycle as the Earth’s rotation. The earth is considered as a stationary satellite, so it is called a geostationary satellite Also known as geostationary satellites), said such a run of orbit geostationary orbit orbit. A typical geostationary satellite orbit is approximately circular with a distance of 35,900 km and a perigee of 35,885 km.
