GEO to GEO Rendezvous NoLead RPO Sequence

The GEO to GEO Rendezvous NoLead RPO sequence creates a rendezvous of one GEO satellite to another GEO satellite using a five-maneuver method.

The first two maneuvers initiate a circular drift towards to the target at a drift rate you specify. The third maneuver matches the target satellite plane with less than two days until final rendezvous.

The final two maneuvers stop the drift rate and match the target satellite's orbit. In this case, the "target satellite" should not be the actual target satellite itself but rather something like a VBar offset to that actual target satellite. The best method is to set the reference satellite to the VBar_Reference satellite prior to using this sequence. Then use the Set_Reference_Vehicle sequence to set the reference vehicle to the target satellite. The GEO to GEO Rendezvous NoLead sequence chooses the actual departure to be either apogee or perigee, depending on the direction of the desired drift toward the target satellite.

The following picture shows a GEO to GEO NoLead rendezvous for a chase satellite at -90 degrees longitude and the target satellite at -105 degrees longitude, using a -3 deg/day (westward) drift.
