ESTIMATING THE ACCURACY OF NAVIGATION SYSTEMS. A STATISTICAL METHOD OF DETERMINING CIRCULAR ERROR PROBABLE

Abstract

A statistical method of estimating the fix accuracy of a navigation system is described. The method is directly applicable to the design or evaluation of hyperbolic systems such as Omega and Loran. It consists of applying a knowledge of system geometry and a simple estimate of the statistical repeatability of measurement to find the circular error probable in a navigational fix. The circular error so determined should be used with caution because it does not account for fixed errors such as map errors. The method was successfully used in evaluation studies of the present Omega network. This report contains an illustrative example of this application.
