VBar to RBar RPO Sequence

The VBar to RBar RPO sequence initiates a partial natural motion circumnavigation (NMC) from an initial VBar position. It stops the NMC at the selected RBar condition (either positive RBar or negative RBar). There are two total maneuvers, one to initiate the NMC from the VBar and one to stop the NMC on the RBar. If the initial position is not on the VBar, the sequence issues an error message and terminates.

The current VBar position dictates the size of the NMC and ultimately the RBar stopping distance relative to the target, which is half the initial VBar relative distance.

The following picture shows an initial position of -500 meters on the VBar and then the final stopping condition at 250 meters on the RBar, using a partial NMC to connect them.
