visible pass

网络释义

可见路径

A pass of a satellite occurs whenever it rises above the observer's horizon; a "visible pass" occurs when all three of the above conditions are satisfied, so the sunlit satellite is seen against a dark sky - this will generally occur either shortly after sunset, or shortly before sunrise. In most cases, the satellite will rise in the west, cross the observer's meridian, and set in the east, although satellites in a polar orbit can rise or set in any part of the sky! Very often the satellite won't be visible for the whole of its passage across the sky, but will either emerge from or enter into the Earth's shadow while above the horizon.
