Abstract

Quasi-Zenith Satellite System (QZSS) is a system that improves performance of Global Positioning System (GPS) in urban areas of Japan. QZSS is designed to transmit the augmentation signals so-called the LEX (L-band Experiment) signal. In this paper, we propose a method to apply the LEX signal and Least-squares AMBiguity Decorrelation Adjustment (LAMBDA) to Precise Point Positioning (PPP), and the positioning performance as well as the accuracy of correction information of LEX the signal are evaluated.
