Australia: Researchers at the Cooperative Research Centre for Spatial Information (CRCSI) in Australia have successfully demonstrated the performance of the Japanese Quasi-Zenith Satellite System (QZSS) LEX signal for precise positioning.

Recently, CRCSI researchers connected GPS systems with the Chinese Navigation Satellite System Beidou for better location search. This latest effort from the CSCRI researchers shows that QZSS LEX could be used to augment GPS and GNSS in providing high accuracy positioning, anywhere, anytime in Australia. It will help in geophysical studies, precision agriculture, airborne and hydrographic surveys etc. LEX is a viable option for precise positioning and navigation in remote regions where GNSS CORS infrastructure is not available or is costly to establish. The LEX signal has a high data transmission rate of 2kbps which allows GNSS correction data to be sent directly to the user’s receiver, providing centimetre-level point positioning accuracy in real-time. The live demonstration was presented at the recent GNSS Symposium and was conducted in partnership with the Japanese Aerospace Exploration Agency.
