Precise Point Positioning Algorithms based on GR models by applying CLAS

Abstract

In this paper, we describe a method of applying CLAS (Centimeter Level Augmentation Service) correction data distributed from QZSS (Quasi-zenith Satellite System) to the algorithm based on our GR (GNSS Regression) models for double frequency PPP of GNSS (Global Navigation Satellite System). Finally, we show the positioning results by applying our algorithms for using actual mesurement data.
