Orbital Elements In Satellite Communication

In this article we will discuss the six classical orbital elements.

Orbital elements in satellite communication.

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 elements are the parameters which are helpful for describing the orbital motion of satellites. Three of the parameters we will use describe how.

It is zero at perigee. The plane contains this body s center. Each element is shown increasing i. Orbital mechanics is the study of the motion of the satellites that are present in orbits.

The six orbital elements none of which were invented by me. 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. We need six parameters to describe the orbit. The excellent youtube channel by mrg3 titled animation for physics and astronomy has a good presentation of each orbital elements.

These elements are used to describe the position of a body in space. 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. Epoch is a number simply stating the time at which that snapshot was taken. This video shows the 6 orbital or keplerian elements.

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. The six orbital elements none of which were invented by me. 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. 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. Following are the orbital elements.

For example moon is a natural satellite of earth. That says given the orbit where the satellite is along that path. 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.
