Orbit phasing

From Wikipedia, the free encyclopedia

In astrodynamics orbit phasing is the adjustment of the time-position of spacecraft along its orbit, usually described as adjusting the orbiting spacecraft's true anomaly.

Orbit phasing is required for a successful approach to a space station in a docking maneuver.
