The model revealed the essence of Einstein¡¯s mathematical constructs and the mechanism for origination of relativistic effects. Moreover, its consistent application produced novel results in particular, constructing a relativity theory based on derivation of its fundamentals out of a thought experiment. Using this approach, the ex-perimentally observed independence of the speed of light from the motion of source and observer was a necessary consequence of the finiteness of propagation speed for all kinds of in-formation. The paper provides a rationale for the logical framework formulated in article [1], and describes the experimental device built to validate the predictions of the theory and the results obtained. %K Principle of Relativity %K Measurement Process %K Lorentz Group %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=70782
