About this exercise type...| equatorial crossing time | albedo | descending pass |
| solar irradiance | polar orbit | nightside |
| sun-synchronous | earthshine | swath |
| ascending pass | near-polar orbit | retrograde orbit |
term — The radiance from the sun arriving at the Earth.
term — The upwelling radiance of the Earth as seen from a satellite.
term — The spectral reflectance of the Earth's surface.
term — A satellite orbit which crosses the north and south poles of the Earth
term — A satellite orbit that is slightly tilted to the north-south axis.
term — A satellite orbit that precesses at almost exactly the same rate that the Earth orbits the Sun (approximately one degree per day)
term — A satellite orbit that precesses (as opposed to one that regresses)
term — The part of a satellite orbit during which the satellite is travelling from south to north
term — The part of a satellite orbit during which the satellite is travelling from north to south
term — The invariable local time at which a sun-synchronous satellite crosses the equator.
term — The track of the satellite on the Earth's surface seen when looking directly downwards.
term — The part of a satellite orbit that is over the night side of the Earth.
