NAVIGATION WITH HIGH-ALTITUDE SATELLITES: A STUDY OF THE EFFECTS OF SATELLITE-USER GEOMETRY ON POSITION ACCURACY

Carole D. Sullivan

Open publisher page 2 citations

Abstract

Abstract : An error analysis of an hyperbolic navigation system using high- altitude satellites revealed that certain satellite arrangements result in long, narrow corridors on the earth (singular regions), in which navigation errors are very large. The study showed that in these singular regions the satellite-user geometry results in navigation equations which are sensitive to measurement errors and thus cannot be solved accurately for all three user coordinates.
