VBar to NM Circumnavigation RPO Sequence

The VBar To NM Circumnavigation RPO sequence initiates an NMC from an initial VBar position. The current initial VBar position must be at least 10 meters from the target, and all relative motion must be zero. The NMC has an option to have a cross-track component when it crosses the RBar, but the other parameters are dictated by being initially on the VBar.

If the initial position is not on the VBar, the sequence issues an error message and terminates.

The following picture shows an NMC initiated from -500 meters on the VBar and then propagated for one revolution.
