The SeaNav 300 navigation sensor is tested and approved in accordance with international regulations as a THD (Transmitting Heading Device), and has Wheelmark certification. The SeaNav 300 provides position and true heading output with no moving parts. The instrument has the potential of replacing several vessel instruments with one compact navigation package (gyrocompass, GNSS receiver equipment, speed log and rate of turn) which outputs heading, position, velocity and rate of turn. FEATURES True heading anywhere on earth 0.5º heading accuracy Heading accuracy unaffected by the latitude Heading available in periods of GNSS drop-outs Compliant to WAAS, EGNOS and MSAS Satellite Based Augmentation Systems Replaces several instruments with one robust, integrated product Only paired cable (no coax) between the mast unit and the equipment on the bridge20 Hz update rate on heading, rate of turn and position measurements (configurable) Output of data on Ethernet 1PPS out synchronization signal INTEGRATION The SeaNav is designed for integration with other navigation equipment and will as default be configured and operated from an ECDIS without the need for a separate external display. The Sensor Unit contains two GNSS receivers and an inertial rate sensor. All operation and functionality are handled from the ECDIS in an integrated bridge system. PERFORMANCE Precision heading is derived from the fixed-distance dual GNSS antenna arrangement in the antenna module, using carrier phase data to generate heading information independent of latitude and vessel dynamics.
