Which condition is required for a satellite to be in a geosynchronous orbit about the Earth?

zero
Three conditions are required for an orbit to be geostationary: The satellite must travel eastward at the same rotational speed as the earth. The orbit must be circular. The inclination of the orbit must be zero.

What is the difference between geostationary and geosynchronous satellites?

While geosynchronous satellites can have any inclination, the key difference to geostationary orbit is the fact that they lie on the same plane as the equator. Geostationary orbits fall in the same category as geosynchronous orbits, but it’s parked over the equator.

Is it possible to have a satellite in geosynchronous orbit around the earth?

A special case of geosynchronous orbit is the geostationary orbit, which is a circular geosynchronous orbit in Earth’s equatorial plane. A satellite in a geostationary orbit remains in the same position in the sky to observers on the surface.

How long will a geosynchronous satellite stay in orbit?

“A satellite in any orbit will continue to orbit 23 hours, 56 minutes, and 8 seconds is the period of a geosynchronous orbit.

What is a geosynchronous satellite used for?

A geosynchronous orbit is a high Earth orbit that allows satellites to match Earth’s rotation. Located at 22,236 miles (35,786 kilometers) above Earth’s equator, this position is a valuable spot for monitoring weather, communications and surveillance.

What is geosynchronous orbit used for?

Is Earth in geostationary or geosynchronous orbit?

Geosynchronous Orbit About 35,786 kilometers above the Earth’s surface, satellites are in geostationary orbit. From the center of the Earth, this is approximately 42,164 kilometers. This distance puts it in the high Earth orbit category.

What does retrograde mean in geosynchronous orbit?

Retrograde essentially means to move backwards. In a geosynchronous orbit, the satellite has an orbital period equal to Earth’s rotation time. That is 23 hours, 56 minutes and 4 seconds.

What is the constant altitude of a geosynchronous orbit?

A circular geosynchronous orbit has a constant altitude of 35,786 km (22,236 mi), and all geosynchronous orbits share that semi-major axis. A special case of geosynchronous orbit is the geostationary orbit, which is a circular geosynchronous orbit in Earth’s equatorial plane.

What are the advantages of a geostationary orbit?

Expanding on the points mentioned in this earlier post, a geostationary orbit or Clarke’s Orbit has quite a few advantages. Due to its altitude, satellites in this orbit can cover a large portion of Earth. Theoretically, only three satellites placed at an appropriate spacing in this orbit are enough to cover the entire Earth.
