VPPP Algorithms with Multiple Antennas by Applying MADOCA Products

Abstract

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.

Positioning Accuracy of Single-Frequency GNSS PPP based on GR Models by using CLAS

“…We have already proposed and examined many cases of movements of the user in [11][12][13][14], similarly to Singer's models [15]. Also several state models for the clock errors cδt u are considered in [16].…”
