The mosaic-CLAS from Septentrio is a GNSS Module that is designed for use in Japan. It supports GPS, GLONASS, Beidou, Galileo, QZSS and SBAS (Egnos, WAAS, GAGAN, MSAS) constellations. This module supports the dedicated L6 signal to enable plug-and-play sub-decimeter accuracy using the integrated PPP-RTK correction service: Centimeter Level Augmentation Service (CLAS) provided by Japan’s Quasi-Zenith Satellite System (QZSS, aka Michibiki). It has 448 hardware channels for simultaneous tracking of all visible supported satellite signals. This GNSS module requires a DC supply of 3.3 V and consumes 0.6 W of power.
The mosaic-CLAS uses Septentrio’s GNSS+ toolset to enable accuracy and reliability in the toughest conditions. This toolset includes AIM+ an advanced on-board interference mitigation technology (narrow and wide band, chirp jammers), LOCK+ for robust tracking during high vibrations and shocks, APME+ multipath mitigation to disentangle direct signals and those reflected from nearby structures and IONO+ provides advanced protection against ionospheric disturbances. It has a cold start of less than 45 seconds, a warm start of less than 20 seconds and a reacquisition time of 1 second. This module has a tracking sensitivity of 20 dB-Hz and an acquisition sensitivity of 33 dB-Hz. It has a velocity accuracy of 3 cm/s, a latency of less than 10 ms and a maximum update rate of 100 Hz.
This module can be controlled via UART, Ethernet, USB 2.0, SDIO and GPIO interfaces. It is available in an SMT solderable LGA package that measures 31 x 31 x 4 mm and is ideal for mass-market applications like robotics and autonomous systems.
