Definitions for "Geosynchronous orbit"
A satellite is in geosynchronous orbit when its orbital period is 24 hours (equal to the earth's rotational period). The satellite remains near the same spot on the Earth (somewhere along the equator).
An orbit in which a satellite rotates with the earth so that the satellite is always above a given spot.
An orbit around the Earth at an altitude where a satellite moves at just the speed at which the planet rotates; hence, an orbit in which an orbiting satellite remains nearly stationary above a particular point on the planets surface.
