Septentrio and CORE Launch a GNSS Receiver Using Japan’s Centimeter Level Augmentation Service

October 10, 2019 Alix Paultre

Septentrio and CORE announced they will jointly develop a receiver that can use the Centimeter Level Augmentation Service (CLAS) of Japan’s Quasi-Zenith Satellite System (QZSS). The two companies have also entered into a distribution contract, which allows CORE to sell Septentrio positioning technology including CLAS-capable GNSS receivers, in the Japanese market.

Septentrio’s multi-frequency GPS/GNSS receiver AsteRx4 will be used as a platform for the development of CLAS functionality. Septentrio receivers already track the L6 signal and can use QZSS for increased positioning availability and reliability. The two companies are planning to launch their CLAS-enabled receiver in January 2020. The new CLAS-enabled receiver will also incorporate Septentrio’s Advanced Interference Mitigation (AIM+) technology, resulting in faster set-up times and robust continuous operation.

Japan’s CLAS is a self-augmentation GNSS correction service. Without the need for a ground link, it allows RTK centimeter-level positioning all over Japan with convergence times of less than a minute. It does this by broadcasting GNSS corrections directly via QZSS satellites, also known as Michibiki. These corrections are generated from the dense network of reference stations operated by Japan’s Geospatial Authority.
