Abstract:
Electronic Navigation Research Institute (ENRI) has been developing a high-accuracy positioning experiment system using a Quasi-Zenith Satellite (QZS) system since 2003. The purpose of this experiment system is to develop technology to determine a position of a mobile user with high accuracy and high integrity. In this experiment system, correction information required to achieve high-accuracy positioning and integrity information are produced at a ground station using GPS data measured at reference stations. This information on correction and integrity is transmitted to mobile users through a QZS. A GPS-like signal will be also produced at a ground station and sent to mobile users combined with the information on correction and integrity through a QZS. A prototype receiver for this experiment will be developed to make sure that our experiment system has expected performance. This paper gives a brief introduction of our experiment system and a development schedule.
