Spacecraft.GetApoapsisRightAscension(Variable) Method

Top 

Description

Returns the right ascension of the apoapsis vector (RAV). The RAV is the equatorial east longitude of the apoapsis vector, referenced to the chosen coordinate frame. This value is only valid for elliptical cases (e < 1), it is invalid for hyperbolic orbits (e > 1) and will report an error. The reference frame will be evaluated at the Spacecraft's epoch.

 

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.
