- An orbital pass (or simply pass) is the period in which a spacecraft is above the local horizon, and thus available for line-of-sight communication with a given ground station, receiver, or relay satellite, or for visual sighting. The beginning of a pass is termed acquisition of signal (AOS); the end of a pass is termed loss of signal (LOS). The point at which a spacecraft comes closest to a ground observer is the time of closest approach (TCA). (en)
- パス とは、宇宙飛行や衛星通信において、衛星またはその他の宇宙機が水平線上にあり、特定の地上局、または中継衛星と無線通信可能（または、場合によっては視認可能）な期間を指す。パスの開始はAOS (acquisition of signal) 、パスの終わりはLOS (loss of signal) と呼ばれる。また、宇宙機が地上の観測者に最も近づく点は、time of closest approachと呼ばれる。 (ja)
