Hop RPO Sequence

The Hop RPO sequence generates a "hop" to move the chase satellite from the current position to a new desired relative position. It accomplishes this in a single maneuver, which occurs at the beginning of the sequence. You specify the duration for the chase satellite to arrive at the desired final relative position.

This sequence does not stop the relative motion at the end. If you want to stop the relative motion at the end of the sequence, use the HopAndStop RPO sequence instead.

The following picture shows a hop from an initial position on the VBar at -1000m to a final position of +500 m on the RBar over two hours of flight time.
