1Orbital Maneuvering System — The Orbital Maneuvering System, or OMS (pronounced /omz/), is a system of rocket engines used on the space shuttle orbiter for orbital injection and modifying its orbit.Cite web|url=http://science.ksc.nasa.gov/shuttle/technology/sts newsref/sts… …
2Orbital Maneuvering System — Das Orbital Maneuvering System (OMS) bildet den Antrieb und mit dem Reaction Control System die Lageregelung der Space Shuttles, nachdem die Haupttriebwerke abgeschaltet wurden und die US Raumfähre ihre Umlaufbahn erreicht hat. Schemazeichnung… …
3Space Shuttle Orbital Maneuvering System — OMS pod schematic The Space Shuttle Orbital Maneuvering System, or OMS (pronounced /omz/), is a system of rocket engines designed and manufactured by Aerojet[1] for use on the space shuttle orbiter for orbital injection and modifying …
4Orbital elements — are the parameters required to uniquely identify a specific orbit. In celestial mechanics these elements are generally considered in classical two body systems, where a Kepler orbit is used (derived from Newton s laws of motion and Newton s law… …
5Orbital perturbation analysis (spacecraft) — Isaac Newton in his Philosophiæ Naturalis Principia Mathematica demonstrated that the gravitational force between two mass points is inversely proportional to the square of the distance between the points and fully solved corresponding two body… …
6Orbital state vectors — In astrodynamics or celestial dynamics orbital state vectors (sometimes state vectors) are vectors of position ( ) and velocity ( ) that together with their time (epoch) ( ) uniquely determine the state of an orbiting body. State vectors are… …
7Orbital inclination — For the science fiction novella by William Shunn, see Inclination (novella). Fig. 1: One view of inclination i (green) and other orbital parameters Inclination in general is the angle between a reference plane and another plane or axis of… …
8Orbital period — For the music album, see Orbital Period (album). The orbital period is the time taken for a given object to make one complete orbit about another object. When mentioned without further qualification in astronomy this refers to the sidereal period …
9Orbital node — The ascending node. An orbital node is one of the two points where an orbit crosses a plane of reference to which it is inclined.[1] An orbit which is contained in the plane of reference (called non inclined) has no nodes …
10Reference ellipsoid — In geodesy, a reference ellipsoid is a mathematically defined surface that approximates the geoid, the truer figure of the Earth, or other planetary body.Because of their relative simplicity, reference ellipsoids are used as a preferred surface… …
