Abstract : In this paper, a formulation of the operative equations that might be employed to filter measurements taken of an atomic clock are developed in an intuitive way. Emphasis is upon making clear, in a practical example, concepts and matrix components that might otherwise appear somewhat abstract to the uninitiated in a formal derivation. Particular attention is given to the concept and calculation of the process noise required to process timing data in a Kalman filter. The author has tried to present the material in such a manner that a person with little or no experience could begin experimenting with the use of a Kalman filter to process real or simulated timing data.
