## What does geosynchronous orbit look like?

At geosynchronous orbit, however, the orbital period of the satellite matches the orbit of the Earth (roughly 24 hours), and the satellite appears virtually still over one spot; it stays at the same longitude, but its orbit may be tilted, or inclined, a few degrees north or south.

## Why does a geosynchronous orbit need to be circular?

This ensures that the satellite will match the Earth’s rotational period and has a stationary footprint on the ground. All geostationary satellites have to be located on this ring.

Why don t synchronous satellites that stay above the same place on the Earth fall down?

Satellites don’t fall from the sky because they are orbiting Earth. Gravity—combined with the satellite’s momentum from its launch into space—cause the satellite to go into orbit above Earth, instead of falling back down to the ground.

### Why don’t we put a geosynchronous weather satellite in orbit around the 45th parallel?

All satellites have planar orbits. That is the orbits of all satellites lie in a plane. That plane must pass through the center of Earth. So we can not put a satellite in an orbit that cuts through the 45th parallel.

### What is the difference between geosynchronous satellite and geostationary satellite?

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.

Do geosynchronous satellites move?

This special, high Earth orbit is called geosynchronous. A satellite in a circular geosynchronous orbit directly over the equator (eccentricity and inclination at zero) will have a geostationary orbit that does not move at all relative to the ground. It is always directly over the same place on the Earth’s surface.

#### What is the difference in potential energy between Earth’s surface and the satellite height for a satellite with 1 kg mass?

Well, we now know that the potential difference between the Earth’s surface and the geostationary orbit height is + 5.3 x 107 J kg-1. In other words, for each kg of mass lifted from Earth to geostationary orbit, 5.3 x 107 J of energy is required.

#### Why the work done by the gravitational force during one full revolution of the probe is zero?

State why the work done by the gravitational force during one full revolution of the probe is zero. because the force is always at right angles to the velocity / motion/orbit is an equipotential surface; Do not accept answers based on the displacement being zero for a full revolution.

What are the differences between geostationary and polar orbiting satellites?

In geostationary orbits, the satellite hovers over a fixed geographical location. Polar orbits are closer to Earth and move with respect to the Earth’s surface, crossing the poles several times each day and observing different longitudes on each pass (as shown in the figure below).

## What is geosynchronous satellite and GSO?

Geosynchronous Satellite and Geosynchronous Orbit (GSO) A geosynchronous satellite is a communication satellite that has an orbital period same as the period of rotation of the earth. Hence, it appears to be permanently in the same area of the sky at a particular time each day when viewed by an observer on the earth.

## What is the orbital period of a geosynchronous satellite?

All geosynchronous orbits have an orbital period equal to exactly one sidereal day. This means that the satellite will return to the same point above the Earth’s surface every (sidereal) day, regardless of other orbital properties. This orbital period, T, is directly related to the semi-major axis of the orbit through the formula:

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.

### How long does it take for the Earth’s rotation to synchronize?

At any inclination, a geosynchronous orbit synchronizes with the rotation of the Earth. More specifically, the time it takes for the Earth to rotate on its axis is 23 hours, 56 minutes and 4.09 seconds, which is the same as a satellite in a geosynchronous orbit.
