Keplerian elements (‘Keps’) provide a mathematical description of a Satellite’s orbit. Satellite tracking software reads the Keplerian elements and provides graphical and/or tabular orbital predictions. Keplerian data are most commonly provided in the AMSAT and the Space Command / NASA Two-Line Element (TLE) format. You can also use the ”kep-char” Excel spreadsheet to determine orbital characteristics of a set of Keplerian elements.

Hi, Take a look at http://asd-www.larc.nasa.gov/Instrument/glossary/k.html good luck.
Hi – I was looking for such a diagram as you have in this article to assist my learning and experimental programming about prediction & decoding Keplerian data – however this diagram does not scale up very well – I’ll print it and see if I can use it
