Marine Satnav Systems provide precise positioning and navigation for vessels using satellite signals. These systems integrate GPS, GLONASS, and other technologies for real-time route planning. They enhance safety and efficiency by offering accurate charts, weather updates, and collision avoidance features.

Marine Satnav Systems typically include GPS, GLONASS, or Galileo compatibility, with accuracy within 1-5 meters. Display sizes range from 7 to 24 inches, often made of marine-grade aluminum or reinforced plastic. Operating temperature ranges from -15°C to 55°C, with waterproof ratings of IPX6 or higher. Viscosity and buoyancy are not applicable. Power requirements are usually 12V or 24V DC.

Navigation Systems may include radar, AIS, and sonar integration. Screen resolutions vary from 800x480 to 1920x1080. Materials are corrosion-resistant, such as stainless steel or ABS plastic. Grade depends on compliance with IEC 60945 or similar marine standards. Buoyancy is not a factor, but shock and vibration resistance are critical. Operating voltages range from 9V to 32V DC.
