Orbital Elements In Satellite Communication

These elements are used to describe the position of a body in space.

Orbital elements in satellite communication. 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. The six orbital elements none of which were invented by me. Orbital elements are the parameters which are helpful for describing the orbital motion of satellites.

Mean anomaly simply states the location of the satellite w r t perigee. 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. Three of the parameters we will use describe how. The effect of orbital elements on geo satellite communication quality abstract.

The excellent youtube channel by mrg3 titled animation for physics and astronomy has a good presentation of each orbital elements. For example moon is a natural satellite of earth. The six orbital elements none of which were invented by me. 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. A satellite orbit is always in a plane around the heaviest body. That says given the orbit where the satellite is along that path. Epoch is a number simply stating the time at which that snapshot was taken.

We know that communication refers to the exchange sharing of information between two or more entities through any medium or channel. Mean anomaly at epoch a set of orbital elements is a snapshot at a particular time of the orbit of a satellite. Orbital mechanics is the study of the motion of the satellites that are present in orbits. So we can easily understand the space operations with the knowledge of orbital motion.

It is zero at perigee. Following are the orbital elements. 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. In general it takes at least six parameters to uniquely define an orbit and a satellite s position within the orbit.

This paper discusses the effect caused by satellite orbit. It s an angular measure from the usual reference point of perigee or orbit s closest approach to earth. Each element is shown increasing i.
