The u-blox concurrent SAM-M8Q GNSS patch antenna module benefits from the exceptional performance of the u-blox M8 multi-GNSS engine.

The SAM-M8Q module offers high sensitivity and minimal acquisition times in an ultra-compact form factor. The SAM-M8Q module utilizes concurrent reception of up to three GNSS systems (GPS, Galileo and GLONASS), recognizes multiple constellations simultaneously and provides outstanding positioning accuracy in scenarios where urban canyon or weak signals are involved.
For even better and faster positioning improvement, SAM-M8Q supports augmentation of QZSS, GAGAN and IMES together with WAAS, EGNOS, and MSAS. SAM-M8Q also supports message integrity protection, geofencing, and spoofing detection with configurable interface settings to easily fit to customer applications
