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].

According to our previous research works, we present the algorithms of the VPPP (Very Precise Point Positions) using multiple GNSS antennas with known distances each other. VPPP algorithms contain the very precise GNSS positioning as well as the so-called GNSS Gyro by estimating the multiple baseline vectors from the reference antenna to other antennas. In this paper, we attempt to implement the satellite orbits and clocks correction data from the MADOCA Products which had been developed by JAXA, into our VPPP algorithms. Further, finally, we show the positioning accuracy as well as the estimation accuracy of the Euler's angles in the GNSS Gyro, in comparison with using the so-called GPS broadcast ephemeris.

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). Throughout the numerical experiments by using the single frequency (L1-band, only) measurement data for the static position, we have very accurate positioning results; namely the total 3D-RMS errors by applying CLAS is approximately 0.13 [m], which is the superior positioning result achieved as a single frequency GPS measurements.
