synchronous orbit

noun

1. astronautics an orbit in which the orbital period of a satellite is identical to the spin period of the central body

synchronous orbit

1. An orbit of a satellite around a rotating body, such that one orbit is completed in the time it takes for the body to make one revolution on its own axis. From the viewpoint of the rotating body (such as Earth), a satellite in synchronous orbit appears to hover over a single position or else to sweep back and forth once per revolution along a single line in the sky. Synchronous orbit is sometimes used synonymously with geostationary orbit, although the two terms are identical only if the synchronous orbit is in the equatorial plane (when the satellite appears to hover motionless over the rotating body). Artificial satellites in synchronous orbits are commonly used in telecommunications, due to their relatively stable overhead position with respect to the Earth's surface.

Example Sentences

So in May 2018 China launched a relay satellite called Queqiao to a gravitationally stable lunar synchronous orbit about 65,000 kilometers beyond the moon, where the gravity of both Earth and the moon keep the relay satellite moving in a halolike motion that ensures it is continuously in sight of both the lunar farside and Earth.
