What is Marinellite Satellite Speed Log GSL9000？

Marine Speed and Distance Measuring Equipment

GSL9000 is Commercial Maritime’s most economic and accurate SDME (Speed Distance Measuring Equipment) system using state of the art technology to provide vessel Distance to Berth and Course Prediction options.
GSL9000 calculates and displays vessel movement information, reporting the ground speed of the vessel’s heading, and sideways movement at the bow and stern, with an accuracy of 0.2 knots, assisting the navigating crew to make informed decisions in all sea states and weather conditions.

Employing all available GPS and GLONASS satellites GSL delivers critical manoeuvring data, worldwide, regardless of sea state or water conditions.

DESIGNED IN COMPLIANCE WITH
• IEC 61023:2007 - Marine Speed and Distance Measuring Equipment (SDME)

• IMO Resolution A.824(19)

• A.694(17)

• MSC.96(72)

• MSC.191(79)

• IEC 60945 (2002)

BENEFITS

• Reliable and accurate globally in any sea state
• Easy retrofit while at sea No through hull fittings; easier to install than a conventional Doppler Docking System.
• Unaffected by water conditions
• Cost effective and reliable – no on-going maintenance

Separate bow and stern sensors measure rather than calculate motion and are completely unaffected by depth and salinity of water, aeration caused by propeller cavitation and other conditions that affect hull mounted sensors.
Whether equipping a new build or for retrofit projects, GSL9000 is an ideal cost effective replacement for Doppler docking systems and can even be installed at sea as no through hull penetrations are required.
