Carrier-Phase-Based PPP with Multiple Antennas Based on GR Models

Sueo Sugimoto, Yukihiro Kubo, and Seigo Fujita

Abstract:	In this paper, we present new carrier-phase-based precise point positioning (PPP) algorithms based on GR models (: GNSS Regression models) by using multiple antennas. Previously we introduced GR equations such that a PPP algorithm was derived which achieved a positioning accuracy at the decimeter error level without any external information such as from WAAS. In this paper, after showing the GR models which contain the so-called receiver’s and satellite’s hardware biases, we extend our PPP algorithm for using multiple antennas. Very precise point positioning (VPPP) algorithms using two or more PPP antennas with common clock errors and known distances among antennas are derived. We formulate a problem of minimum mean square estimation with the constraints so that the recursive VPPP algorithms are derived. Finally experimental results show the feasibility of the present VPPP algorithms.
