Designed for hydrographic surveying, dredging, oceanographic research, seismic work and offshore construction. A 555 channel-dual frequency sensor that utilises GPS, GLONASS, Galileo, Beidou and QZSS satellites. It uses standard DGNSS (SBAS), Fugro XP2/G2/G4/G4+ and RTK differential corrections. Position accuracy: 1 cm + 1 ppm RMS. Roll/pitch accuracy: 0.008 degrees RMS. Heading accuracy: 0.04 degrees RMS (2.5m baseline), 0.02 degrees RMS (4m baseline). Heave accuracy: 2 cm or 2 % (delayed-mode), 5 cm or 5 % (real-time)."@en ; skos:notation "SDN:L22::TOOL1615" ; skos:note "accepted"@en ; skos:prefLabel "Kongsberg Seatex Seapath 380 5+ global positioning and attitude sensor"@en ; skos:related , .
