Exit Eccentricity Vector RPO Sequence

The Exit Eccentricity Vector RPO sequence initiates a drifting orbit relative to the target satellite while maintaining the eccentricity vector (both eccentricity and argument of periapsis) of the target satellite. You are responsible to ensure flight safety during the exit sequence.

Generally, if exiting westward, the chase satellite should be above the target before initiating the sequence. If exiting eastward, the chase satellite should be below the target before initiating the sequence. The picture below shows an eastward drift rate.

Sequence Parameters

Option	Description
Delta_Phase	Enter the delta phase angle in degrees/rev after the two-burn sequence . This value is positive to move east relative to target, and negative to move west relative to target.
Engine_Name	Enter, as a string, the name of the finite maneuver engine model.
Maneuver_Type	Select the type of maneuver, "Impulsive" or "Finite," from the drop-down list.
WhoAmI	Enter, as a string, the name of the current satellite.
ThisSequence	Enter, as a string, the name of this sequence. This is nominally Exit_EccVector, but if you insert the sequence multiple times in the MCS, Astrogator adds a monotonically increasing number on the end of the name each time (Exit_EccVector1, Exit_EccVector2, etc.)
