Calc Objects for maintaining a repeating ground track.

Name Dimension Type Description
Time DateFormat Real Number Time.
RepeatingGroundTrackEquatorError DistanceUnit Real Number The difference between the current longitude and the nearest grid point longitude computed as point of an orbit with the specified repeat count and reference longitude. This Calc Object should only be evaluated at an XY plane crossing. The reference longitude can range from -360 to 360 deg. The repeat count gives the number of orbits before the ground track repeats over the same longitude. The Calc Object allows a choice of a central body. The default is Earth.
