Orbital Elements In Satellite Communication

We need six parameters to describe the orbit.

Orbital elements in satellite communication.

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. The excellent youtube channel by mrg3 titled animation for physics and astronomy has a good presentation of each orbital elements. This paper discusses the effect caused by satellite orbit.

Each element is shown increasing i. It is zero at perigee. A satellite orbit is always in a plane around the heaviest body. Following are the orbital elements.

Epoch is a number simply stating the time at which that snapshot was taken. Three of the parameters we will use describe how. For example moon is a natural satellite of 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.

The orbital elements this system has six degrees of freedom. Orbital elements are the parameters which are helpful for describing the orbital motion of satellites. We know that communication refers to the exchange sharing of information between two or more entities through any medium or channel. Mean anomaly simply states the location of the satellite w r t perigee.

It s an angular measure from the usual reference point of perigee or orbit s closest approach to earth. These elements are used to describe the position of a body in space. In this article we will discuss the six classical orbital elements. Orbital mechanics is the study of the motion of the satellites that are present in orbits.

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

That says given the orbit where the satellite is along that path. Mean anomaly at epoch a set of orbital elements is a snapshot at a particular time of the orbit of a satellite. The effect of orbital elements on geo satellite communication quality abstract.
