任务简介

Syncom 2 是首颗地球同步卫星。尽管其轨道周期为24小时，且航天器保持在几乎恒定的经度上，但轨道倾角为33度，因此并非真正的地球静止卫星，而是在赤道南北33度范围内沿拉长的8字形轨迹运动。

原文

Syncom 2 was the first geosynchronous satellite. Although the period was 24 hours and the spacecraft remained at a nearly constant longitude, the orbit was inclined at 33 degrees so it was not truly geostationary but moved in an elongated figure eight pattern 33 degrees north and south of the equator.
