Bridging GPS Gaps in Urban Canyons: The Benefits of ZUPTs

This paper describes a study which looked at the impact of zero velocity updates (ZUPTs) on navigation accuracy in urban canyons. Focus was on the speed and reliability of ambiguity resolution supported by periodic ZUPTs. The paper also presents an analysis of the positioning errors after ZUPT events versus unaided and GPS/inertial navigation system (INS) results. The observability aspects of static INS calibration are also briefly addressed.
