Abstract: The effect of the geometrical relationship between course-line and ground statiosn on area navigation errors is analyzed. The analysis is applied to both the RHO/THETA and RHO/RHO systems. Graphs for determining the along-course and cross-course error standard deviations for both systems are presented. The concepts of trading off along-course precision for cross-course precision and the selection of geometrically optimal ground station configurations are discussed and illustrated. The results of this paper are of oeprational value since they can be used to sequence ground station selections and determine the feasibility of existing ground stations to provide are navigation for the traffic patterns of a given geographical region.
