看来我还是对地球同步轨道理解有偏差啊。

A satellite whose orbital period is equal to the rotational period of the Earth is said to be in a geosynchronous orbit. Its ground track will have a "figure eight" shape over a fixed location on the Earth, crossing the equator twice each day. It will track eastward when it is on the part of its orbit closest to perigee, and westward when it is closest to apogee.

按照这个定义，只要周期跟地球自转周期一样就可以。没有要求是圆的。
所以椭圆可以很椭，轨道平面可以跟赤道平面差很远。
所以8字也可以很大。

: 不不，8字不是一般的大
