designating or of a satellite or spacecraft in an orbit above the equator, revolving at a rate of speed synchronous with that of the earth's rotation so that it always stays above the same place on the earth's surface
- Of, relating to, or being a satellite that travels above earth's equator from west to east at an altitude of approximately 35,900 kilometers (22,300 miles) and at an angular speed matching that of the earth's rotation, thus remaining stationary as observed from any location on the earth's surface.
- Of, relating to, or being the orbit of such a satellite.
- At a fixed distance in three dimensions relative to a particular point on the Earth's surface; generally only possible with orbital satellites.
