Orbital Elements In Satellite Communication

That says given the orbit where the satellite is along that path.

Orbital elements in satellite communication.

The excellent youtube channel by mrg3 titled animation for physics and astronomy has a good presentation of each orbital 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. This video shows the 6 orbital or keplerian elements. The orbital elements this system has six degrees of freedom.

Orbital mechanics is the study of the motion of the satellites that are present in orbits. 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 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. This paper discusses the effect caused by satellite orbit.

The plane contains this body s center. For example moon is a natural satellite of earth. These elements are used to describe the position of a body in space. We need six parameters to describe the orbit.

Satellite communication 1 in general terms a satellite is a smaller object that revolves around a larger object in space. Following are the orbital elements. Orbital elements are the parameters which are helpful for describing the orbital motion of satellites. In this article we will discuss the six classical orbital elements.

The six orbital elements none of which were invented by me. Three of the parameters we will use describe how. Mean anomaly at epoch a set of orbital elements is a snapshot at a particular time of the orbit of a satellite. Each element is shown increasing i.

So we can easily understand the space operations with the knowledge of orbital motion. Mean anomaly simply states the location of the satellite w r t perigee. It is zero at perigee. 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. In general it takes at least six parameters to uniquely define an orbit and a satellite s position within the orbit. The effect of orbital elements on geo satellite communication quality abstract.
