RBar to Vbar RPO Sequence

The RBar to VBar sequence moves the chase satellite from an initial RBar position to a final VBar position using a partial Natural Motion Circumnavigation (NMC). You can specify the final condition as either positive VBar or negative VBar. If the initial position is not on the RBar, the sequence issues an error message and terminates execution.

The sequence generates an initial maneuver to start the NMC from the RBar and a second to stop the NMC on the VBar. The initial RBar position dictates the size of the NMC and ultimately the VBar stopping distance relative to the target, which is twice the initial RBar relative distance.

The following picture shows an initial chase satellite position of -1000 meters on the RBar and then the final stopping condition at -2000 meters on the VBar, using a partial NMC to connect them.
