THE ROLE OF THE EARTH'S SHAPE IN NAVIGATION: AN EXAMPLE

Abstract:	The accuracy of navigational fixes obtainable with present day navigation systems is such that the Earth’s geodesy must be considered, especially in comparing relative fixes. Approximations to the exact transformations between geodetic and geocentric coordinates can be made so as to optimize computer times. This paper presents the results of a systematic error analysis of these approximations to the exact coordinate transformations and the resulting real-time and core requirements on an AN/UYK-20 standard Navy mini-computer.
