Spacecraft.LongDescendingNodeErrorRate(Variable, Variable) Method

Top

Description

Returns the change in the average longitude of descending node error with respect to time. The longitude of descending node error is the offset from a user-defined global reference longitude grid measured at the Descending 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. Note that this property is Earth-specific.

Timing Precision Mode

This page describes functionality in millisecond timing precision mode. Millisecond timing precision mode is deprecated and will be removed in a future release. We recommend that you migrate your Mission Plans to nanosecond timing precision mode.
