Abstract:	With the advent of multiple Global Navigation Satellite Systems (GNSS), many organizations will need to be able to evaluate GNSS coverage efficiently. Undergraduate students from the UCLA Research in Industrial Projects for Students (RIPS) program combined their efforts with engineers from The Aerospace Corporation to determine efficient algorithms for computing the position, horizontal, vertical, and time dilutions of precision. Formulas include efficient derivative calculations both for determining time intervals of coverage as well as optimizing positions of satellites to maximize coverage. This paper describes the results obtained from the study and provides generalizations of the results applicable to multi-GNSS navigation relying upon different timing systems. The generalizations of the result for multiple GNSS include efficient formulas for supporting satellite selection and receiver autonomous integrity monitoring (RAIM) algorithms.
