A rugged CORS-class GNSS reference receiver built around ComNav's K8 platform, tracking 1590 channels across all current and planned satellite constellations (GPS, GLONASS, BeiDou, Galileo, QZSS, IRNSS, SBAS). It houses an IP67 aluminum enclosure, a built-in web server for remote configuration and firmware updates, and large onboard storage (32 GB, expandable) for continuous reference-station logging over RTCM, NMEA, BINEX and NTRIP.
