绪言静止卫星这个词从字面上看是静止的人造卫星,而这是从地球上观看时的事情,实际上卫星以每秒3公里的速度环绕地球公转,不过由于公转的角速度选择为与地球自转的角速度一致,于是从地球上看来,卫星恰恰象停留在一点上似地静止不动。这种从地球上也就是从接收天线设置处所看来显得停留不动的静止卫星,使得接收天线可以固定地设置从而廉价地
INTRODUCTION The term geostationary satellites is literally a stationary satellite, and this is what it looks like when viewed from the earth. In fact, the satellites revolve around the Earth at a speed of 3 kilometers per second. However, since the angular velocity of revolution is chosen to be the same as that of the Earth The angular velocity of the same, so from the Earth’s point of view, the satellite is just like a little stay on the stand still. Such geostationary satellites, which appear to be stationary from the point of view of the earth, that is, from the place where the receiving antenna is installed, allow the receiving antenna to be fixedly disposed so as to be inexpensively
