ERROR SENSITIVITY MODEL

A computer model was written to simulate errors associated with the Coast Guard aids to navigation positioning process with emphasis placed on finding average effects of errors in the system. A mathematical expectation approach was used to model random system elements. The model routines have been designed to study specific positioning situations or, by use of Monte Carlo Methods, a variety of situations as a group. The model was designed for use in planning within the aid positioning macrostructure. For planning purposes, the probability that the resulting position lies within a specific circular region is a meaningful measure of positioning success. The model was exercised for numerous cases and offers a priority listing of errors. (Author)
