Retry/recovery method in rendezvous manoeuvre.

摘要

In a rendezvous manoeuvre for approaching a rendezvous spacecraft to a target spacecraft via a reference trajectory ( l ) for approach which is different in altitude and period from the trajectory of the target spacecraft, if the rendezvous spacecraft is deviated from the reference trajectory for approach as a result of , for instance a failure in the manoeuvre, it is first manoeuvred in the direction of altitude after 0.2 revolutions, and then manoeuvred in the direction of phase after another 0.2 revolutions. The rendezvous spacecraft is thereby restored to the reference trajectory without entering a collision course, so that a highly reliable retry/recovery may be performed promptly and safely.
