12synchronous satellite — synchronous satellite, an artificial satellite whose orbit is synchronous with the rotation of the earth on its axis. It orbits the earth once every 24 hours at a fixed altitude above the equator, and thus appears to be stationary; geostationary… …
13synchronous — ► ADJECTIVE 1) existing or occurring at the same time. 2) referring to a satellite which revolves in its orbit in exactly the same time as the primary body rotates on its axis. DERIVATIVES synchronously adverb. ORIGIN Greek sunkhronos, from sun… …
14Orbit of the Moon — Not to be confused with Lunar orbit in the sense of a selenocentric orbit, that is, an orbit around the Moon The Moon completes its orbit around the Earth in approximately 27.3 days (a sidereal month). The Earth and Moon orbit about their… …
15Orbit equation — In astrodynamics an orbit equation defines the path of orbiting body around central body relative to , without specifying position as a function of time. Under standard assumptions, a body moving under the influence of a force, directed to a… …
16Orbit phasing — 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. This is predominantly used in satellite positioning, especially if the… …
17synchronous equatorial orbit — noun a circular orbit in which a satellite moves around the earth once while the earth rotates once on its axis and thus remains fixed above a particular point above the equator; geostationary orbit; stationary orbit …
18orbit, subsynchronous satellite — A satellite orbit that is at lower altitude than the 35,880 kilometers required for a synchronous equatorial orbit …
19synchronous rotation — Astron. rotation of a satellite in which the period of rotation is equal to the period of orbit around its primary, leaving the same face always pointing toward the primary: The moon is in synchronous rotation about the earth. [1970 75] * * * …
20synchronous rotation — Astron. rotation of a satellite in which the period of rotation is equal to the period of orbit around its primary, leaving the same face always pointing toward the primary: The moon is in synchronous rotation about the earth. [1970 75] …
