Orbital Elements In Satellite Communication

In general it takes at least six parameters to uniquely define an orbit and a satellite s position within the orbit.

Orbital elements in satellite communication.

Following are the orbital elements. These elements are used to describe the position of a body in space. This video shows the 6 orbital or keplerian elements. The effect of orbital elements on geo satellite communication quality abstract.

In this article we will discuss the six classical orbital elements. Epoch is a number simply stating the time at which that snapshot was taken. It is zero at perigee. For example moon is a natural satellite of earth.

Three of the parameters we will use describe how. Satellite communication 1 in general terms a satellite is a smaller object that revolves around a larger object in space. Mean anomaly simply states the location of the satellite w r t perigee. Orbital elements are the parameters which are helpful for describing the orbital motion of satellites.

We need six parameters to describe the orbit. The six orbital elements none of which were invented by me. Mean anomaly at epoch a set of orbital elements is a snapshot at a particular time of the orbit of a satellite. That says given the orbit where the satellite is along that path.

So we can easily understand the space operations with the knowledge of orbital motion. The plane contains this body s center. 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. It s an angular measure from the usual reference point of perigee or orbit s closest approach to earth.

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. This paper discusses the effect caused by satellite orbit. A satellite orbit is always in a plane around the heaviest body. The orbital elements this system has six degrees of freedom.

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. Orbital mechanics is the study of the motion of the satellites that are present in orbits.
