MULTI-BAND GNSS Multi-band GNSS provides precise location accuracy1 to within 1 meter to compatible marine multifunction displays, instrument displays and autopilots. MAGNETIC HEADING The magnetic heading sensor provides accuracy to within 3 degrees, stabilizing charts, radar overlay and MARPA even at slow speeds. HIGH-SENSITIVITY GPS Fast 10 Hz position update rates provide high-sensitivity position, velocity and time data. EXPANDED GNSS SUPPORT GPS 24xd provides access to four key global navigation satellite systems (GPS, Galileo, GLONASS and BeiDou) to more accurately track in challenging conditions than GPS alone. MULTI-SBAS COMPATIBLE Multi-SBAS compatibility corrects signal measurement errors and provides information about the accuracy, integrity, continuity and availability of its signals. MOUNTING OPTIONS Installation is easy with under-deck, pole and surface-mount options.
