...In the case of a geostationary satellite, after it is first placed in this low-altitude orbit (this orbit is called a parking orbit), it is then placed into a transfer orbit called a Hohmann transfer (Hohmann orbit). The final insertion into a geostationary orbit is performed by igniting an apogee motor (a small solid rocket) at the apogee of this transfer orbit, and the satellite is placed into a drift orbit that is very close to a geostationary orbit. In this drift orbit, the satellite's own small engines repeatedly correct its orbit and keep it stationary. ... *Some of the terminology explanations that mention "drift orbit" are listed below.

…静止衛星投入の場合には,この低高度軌道にいったん乗せた後(この軌道をパーキング軌道parking orbitという),さらにホーマン型移行(ホーマン軌道)と呼ばれる遷移軌道transfer orbitへの投入が行われる。静止軌道への最終投入は,この遷移軌道の遠地点でアポジモーター(小型の固体ロケット)を点火することにより行われ,衛星は静止軌道にきわめて近いドリフト軌道drift orbitへ投入される。このドリフト軌道において,衛星自身のもつ小型エンジンにより軌道修正が繰り返され静止させられるのである。… ※「drift orbit」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
