POSITION FIXING BY TIME OF ARRIVAL

Abstract

An engineering model is developed of the error contours encountered in position fixing using synchronous time of arrival data. Normal distribution is emphasized. Probabilities of fixes occurring within circles and ellipses are determined using the natural oblique coordinates associated with the measuring system. Comparisons are made of three-observer and four-observer configurations. Examples are provided and applications are discussed.
