Eclipse

When enabled the Eclipse constraint will ensure that no sensing operation is performed when the satellite is in Eclipse. This occurs when the line of sight between satellite and the Sun is obstacled by the Earth.

It is possible to provide a margin to the Eclipse boundaries to advance or delay the effective start and stop of the Eclipse period, i.e. the constrain is applied in the time window [tEnterEclipse - tMargin, tExitEclipse + Margin]. The Margin can be positive or negative. The constraint is activated at sensor level in the properties grid and via the Sensor Wizard.

It is also possible to define how swaths will be trimmed, whether inside or outside. If OUTSIDE is selected, then the sensor will operate only within the eclipse.

INSIDE: Swath sections inside the eclipse will be removed
OUTSIDE: Swath sections outside the will be removed
