Special Report (in English)
Highly-Accurate Positioning Experiment Using QZSS at ENRI
Ken Ito, Electronic Navigation Research Institute (ENRI)
"Positioning accuracy with GPS may not be sufficient for high-speed mobile users such as trains or cars. These difficulties require the development of new satellite positioning technology. QZSS (Quasi-Zenith Satellite System) is considered to be a possible candidate to solve these difficulties." The first Quasi-Zenith Satellite was launched in September 11, 2010. ENRI has started an experimental project to study highly accurate positioning technologies with an L1-SAIF (sub-meter class augmentation with integrity function) signal developed based on SBAS standard. The target of user position accuracy is set to one meter rms. This article will introduce the ENRI experimental system and recent results.

Reviewer: Takashi Iida, Editorial Advisor
"I know the name of "RAND" as a research institute about national security, but thought to the degree whether it is one of research institutes affiliated to the Massachusetts Institute of Technology. However, this was wrong belief. This book is translated into Japanese in 2008. Then I will introduce contents of this book briefly below."
