Spacecraft.LongDescendingNodeError(Variable, Variable) Method

Top 

Description

Returns the offset from a user-defined global reference longitude grid measured at the Ascending Node, also referred to as a repeating groundtrack grid. The repeating groundtrack grid represents the nominal nodal longitudes the Spacecraft would fly over, spaced evenly around the equator. The spacing of the grid is dependent on the number of orbits in the repeat cycle. Note that this property is Earth-specific.
