Koki Asari, Masayuki Saito, and Hisao Amitani

Abstract:	Japanese Quasi-Zenith Satellite System (QZSS) provides the Centimeter Level Augmentation Service (CLAS) using Compact State Space Representation (SSR) correction data. It enables Precise Point Positioning (PPP) in Real-Time Kinematic (RTK) networks. This method is called PPP-RTK GNSS positioning, which realizes centimeter-level positioning accuracy and very fast convergence within one minute, anytime and anyplace all over the country. The Japanese government also announces ground-based augmentation using the same correction data, therefore it recently become able to study to apply PPP-RTK to smartphones. This paper presents the discussion on the PPP-RTK applicability using ground-based assist service, the development of SSR assist system, the application configuration in a smartphone, positioning accuracy, and worldwide applicability of PPP-RTK GNSS positioning.
