parking orbit

An orbit in which a satellite or spacecraft can be placed before being injected into a final orbit or desired trajectory.

parking orbit

[′pärk·iŋ ‚ȯr·bət]
(aerospace engineering)
A temporary earth orbit during which the space vehicle is checked out and its trajectory carefully measured to determine the amount and time of increase in velocity required to send it into a final orbit or into space in the desired direction.
