Positioning Accuracy of Single Frequncy GNSS PPP by CLAS Comparing with MADOCA Products

抄録

In this paper, we present the single frequency PPP algorithms based on our GR models with applying CLAS(Centimeter Level Augmentation Service) data from Japan Quasi-Zenith-Satellite-System (QZSS), comparing with the positioning results applying the MADOCA (Multi- GNSS Advanced Demonstration tool for Orbit and Clock Analysis) Products which had been developed by JAXA (Japan Aerospace Exploration Agency) and are provided by GPAS (Global Positioning Augumentation Service Corporation), Throughout the numerical experiments the total 3DMMS error by applying CLAS is approximately 0.28 [m], in contrary with the total 3DMMS error by applying MADOCA Productsis being aproximately 0.52 [m].
