In orbital mechanics, speed and altitude are linked: a satellite or a ship orbits a body at a given altitude and a given speed (at least that's what I understand). A rendezvous usually takes place in orbit, e.g. 8. Description. First, three time-varying coordinate transformations are derived which relate the Hill-Clohessy-Wiltshire equations to the Lin-earized Equations of Relative Motion. Some introduction to perturbations and linear algebra 4. 1. If two spacecraft are close enough to each other (< 300m) and travel in similar orbits they are said to rendezvous. 9 Page 2/10. 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. When moving away from the source it is called an escape orbit, otherwise a capture orbit.It is also sometimes referred to as a C 3 = 0 orbit (see Characteristic energy).

In astrodynamics or celestial mechanics a parabolic trajectory is a Kepler orbit with the eccentricity equal to 1 and is an unbound orbit that is exactly on the border between elliptical and hyperbolic. A calibration point: At the start of the ISS visiting vehicles project, the ISS office insisted that the ISS could have an eccentricity as high as 0.015 and that any visiting vehicle must be able to accommodate that. Relative motion, Hill’s equations, rendezvous and docking. This parameter indicates the deviation of the orbit’s shape from a perfect circle. periapsis.
