Nominal Range Error Analysis to Support ARAIM [PDF]

open access: yesION GNSS+, The International Technical Meeting of the Satellite Division of The Institute of Navigation, 2016
This paper presents a nominal range error analysis to support ARAIM based on a statistical study of orbit and clock errors observations for Galileo F-NAV Open Service. Nominal range error is characterized by the so-called Signal-in-Space Range Error (SISRE) which is computed by comparing precise reference orbits to broadcast ephemeris for each ...
