High Accuracy Real-Time Precise Point Positioning using the Japanese Quasi-Zenith Satellite System LEX Signal
نویسندگان
چکیده
The Quasi-Zenith Satellite System (QZSS) is a regional navigation satellite system transmitting navigation signals that are compatible and interoperable with GPS, as well as transmitting augmentation signals that carry bias correction messages. The L-band Experimental (LEX) signal on the E6b frequency delivers correction messages – such as orbits and clock information, which enable Precise Point Positioning (PPP). Since March 2013, Australian and Japanese researchers have conducted collaborative investigations in order to evaluate the QZSS LEX signal and the quality of the broadcast correction messages for real-time PPP. The QZSS LEX has been tested in both static and kinematic positioning modes in Australia. The results have been compared to positioning solutions derived from conventional positioning techniques such as Real-Time Kinematic (RTK), as well as those derived from the International GNSS Service’s (IGS) real-time service. Decimetre level positioning accuracies in real-time have been obtained in both static and kinematic tests. Furthermore, a prototype system of an ‘Australian-generated LEX corrections’ has been developed. This paper presents the results of investigations into the feasibility of using the QZSS LEX signal to deliver a high accuracy real-time positioning service to Australian GNSS users. This is a collaborative research project between the Australian Cooperative Research Centre for Spatial Information and Japan Aerospace Exploration Agency (JAXA).

The Possibility of Precise Positioning in the Urban Area
A third civil frequency at 1176.45MHz will be added to the GPS system. QZSS (Quasi Zenith Satellite System) proposed by Japan will also have the new signal. This new frequency and the advent of QZSS will greatly enhance the accuracy, reliability and robustness of civilian GPS receivers. One of these enhancements is that it is possible to determine the GPS phase ambiguities more or less instanta...

Japan has been developing a new satellite based positioning system called Quasi-Zenith Satellite System (QZSS). Since improvement of positioning availability in urban area is one of the most important advantages of the QZSS, multipath mitigation is a key factor for the QZSS positioning system. Therefore, Japan Aerospace Exploration Agency (JAXA) and GNSS Inc. developed a pseudolite, which trans...

The remote synchronization system RESSOX is a novel concept for a GNSS time keeping system that does not require an on-board atomic clock. RESSOX has been presented as an alternative to the classic GPS scheme and was specifically designed for the Japanese augmentation system QZSS (Quasi-Zenith Satellite System). According to the RESSOX structure, QZSS satellites will carry light and inexpensive...
