Orbital Elements In Satellite Communication

It is zero at perigee.

Orbital elements in satellite communication.

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. For example moon is a natural satellite of earth. Mean anomaly simply states the location of the satellite w r t perigee. Epoch is a number simply stating the time at which that snapshot was taken.

Each element is shown increasing i. The six orbital elements none of which were invented by me. It s an angular measure from the usual reference point of perigee or orbit s closest approach to earth. The excellent youtube channel by mrg3 titled animation for physics and astronomy has a good presentation of each orbital elements.

We need six parameters to describe the orbit. 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. In general it takes at least six parameters to uniquely define an orbit and a satellite s position within the orbit. In this article we will discuss the six classical orbital elements.

These elements are used to describe the position of a body in space. Satellite communication 1 in general terms a satellite is a smaller object that revolves around a larger object in space. The effect of orbital elements on geo satellite communication quality abstract. Following are the orbital elements.

This video shows the 6 orbital or keplerian elements. The plane contains this body s center. The orbital elements this system has six degrees of freedom. So we can easily understand the space operations with the knowledge of orbital motion.

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 six orbital elements none of which were invented by me. That says given the orbit where the satellite is along that path.

This paper discusses the effect caused by satellite orbit. Orbital elements are the parameters which are helpful for describing the orbital motion of satellites. A satellite orbit is always in a plane around the heaviest body.
