...Therefore, orbital control during launch is planned mainly for the final insertion phase, specifically, launch timing, attitude control, and, if possible, injection time control. In the case of a geostationary satellite, after it is placed in this low-altitude orbit (this orbit is called a parking orbit), it is inserted into a transfer orbit called a Hohmann type transfer (Hohmann orbit). Final insertion into geostationary orbit is performed by igniting an apogee motor (a small solid rocket) at the apogee of this transfer orbit, and the satellite is inserted into a drift orbit that is very close to geostationary orbit. ... *Some of the terminology that mentions "parking orbit" is listed below.

…したがって打上げ時の軌道制御は主として最終投入段階に対して計画され,具体的には打出しのタイミング,姿勢制御,さらに可能ならば噴射時間制御が行われる。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。… ※「parking 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 |
