Gps bias correction
WebJun 23, 2013 · This paper presents a precise localization method for autonomous driving systems by correcting the GPS bias error. Since GPS errors have systematic noise properties that change slowly with time, a stand-alone GPS cannot be used for localization of an autonomous vehicle. WebJan 13, 2015 · GNSS (e.g., GPS, GLONASS, and BDS) pseudoranges are well known to be affected by instrumental biases (Rao 2007; Li et al. 2014 ). To cope with this problem, …
