In orbital mechanics, a frozen orbit is an orbit for an artificial satellite in which natural drifting due to the central body's shape has been minimized by careful selection of the orbital parameters. Typically, this is an orbit in which, over a long period of time, the satellite's altitude remains constant at the same point in each orbit. Changes in the inclination, position of the apsis of the orbit, and eccentricity have been minimized by choosing initial values so that their perturbations cancel out., which results in a long-term stable orbit that minimizes the use of station-keeping propellant.

rdfs:comment	In der Raumflugmechanik ist ein Frozen orbit (dt. eingefrorener Orbit) ein Satellitenorbit, bei dem die durch die Erdform erzeugte natürliche Drift durch sorgfältig ausgesuchte Bahnparameter minimiert ist. Typischerweise ist das ein Orbit, bei dem über eine lange Zeitspanne die Höhe bei einem bestimmten Punkt im Orbit gleich bleibt. Änderungen in der Bahnneigung, des Argument des Perigäums, und der Exzentrizität werden durch die Auswahl von Startwerten so minimiert, dass ihre Störungen sich aufheben. Das erzeugt einen langzeitstabilen Orbit mit reduziertem Treibstoffbedarf zum Ausgleich der Bahnstörungen.

reason	section is relevant as it explains why frozen orbits exist, but may be difficult for laymen to understand. The mathematics should be retained, but with additional information and explaination. (en)
