Orbital Elements In Satellite Communication

We need six parameters to describe the orbit.

Orbital elements in satellite communication.

Mean anomaly at epoch a set of orbital elements is a snapshot at a particular time of the orbit of a satellite. The antenna pointing accuracy of geo satellites has quite a few effects on communication quality while pointing accuracy is mainly affected by satellite orbit and attitude. The six orbital elements none of which were invented by me. Epoch is a number simply stating the time at which that snapshot was taken.

Each element is shown increasing i. This video shows the 6 orbital or keplerian elements. The mean element set format also contains the mean orbital elements plus additional information such as the element set number orbit number and drag characteristics. Following are the orbital elements.

A satellite orbit is always in a plane around the heaviest body. In general it takes at least six parameters to uniquely define an orbit and a satellite s position within the orbit. Mean anomaly simply states the location of the satellite w r t perigee. That says given the orbit where the satellite is along that path.

It is zero at perigee. The excellent youtube channel by mrg3 titled animation for physics and astronomy has a good presentation of each orbital elements. Satellite communication 1 in general terms a satellite is a smaller object that revolves around a larger object in space. The orbital elements this system has six degrees of freedom.

So we can easily understand the space operations with the knowledge of orbital motion. These elements are used to describe the position of a body in space. Three of the parameters we will use describe how. For example moon is a natural satellite of earth.

The six orbital elements none of which were invented by me. We know that communication refers to the exchange sharing of information between two or more entities through any medium or channel. The effect of orbital elements on geo satellite communication quality abstract. This paper discusses the effect caused by satellite orbit.

In this article we will discuss the six classical orbital elements. Orbital elements are the parameters required to uniquely identify a specific orbit in celestial mechanics these elements are considered in two body systems using a kepler orbit there are many different ways to mathematically describe the same orbit but certain schemes each consisting of a set of six parameters are commonly used in astronomy and orbital mechanics. The plane contains this body s center.
