The SC-50 is a new satellite compass that uses Furuno’s advanced GPS technology. This satellite compass can be used for a wide range of applications for any type of vessel. Radar/ARPA, AIS, ECDIS, Scanning Sonar and Autopilots can utilize the functions of this compass. The SC-50 uses GPS carrier frequency to determine heading and is not affected by ship’s speed, latitude, geomagnetism, etc. Settling time is nearly instantaneous and the follow-up performance is excellent, achieving 45°/s (SOLAS HSC Code requires 20°/s as a minimum).
The SC-50 delivers GPS positioning, SOG (Speed Over Ground), COG (Course Over Ground) and ROT (Rate of Turn). SOG is remarkably accurate through decoding the Doppler shift in the received satellite signals. The information can be output in IEC61162-2 format at the high update rate up to 38.4 kbps to satisfy the high speed data-output requirements in special applications.
The SC-50 has a unique Set and Drift mode. When connected with a water-tracking speed log, it calculates set and drift (tide direction and speed) in the mode. The display helps a radar operator manually enter set and drift for the accurate sea stabilization pictures.

The JLR-21/31 GPS compass continues the success of its predecessor, reaching a new level of performance and stability with many new features and enhancements. This system is also known as a 3D Dynamic Sensor, which besides giving heading information, is designed to provide highly accurate information of the ships movement in all axis.
The JLR-21/31 has heave functionality built-in as standard. In rough ocean conditions (with high waves), the GPS compass can correct up and down (attitude), movement. This is especially useful for fish finders and sonars on fishing vessels where high waves are compensated for with up to 20 cm accuracy, providing better potential for a profitable catch.
JLR-21/31 supports Speed Over Ground (SOG) and Course Over Ground (COG). The position, SOG and COG are updated every 200 milliseconds (which is 5 times faster than previous model JLR-20), delivering high accuracy.
The GPS compass has its origins as a direction sensing system, but the JLR-21/31 goes far beyond that. The JLR-21 provides heading accuracy of 0.5° and the JLR-31 has an impressive 0.25° heading accuracy. Heave accuracy is 20 cm or better and roll and pitch for both models is 0.5°. The tracking Rate of Turn (ROT) is 45° per second.
The JLR-21/31 incorporates many display modes readily available on a highly visible 5.7 inch LCD display. The display is fully dimmable and the keys are also backlit, making it easy to operate in low-light settings on the bridge.
The processor is built into the antenna. Eliminating alignment between antenna and processor found in separate systems, therefore contributing to an easy setup with less error and significantly reduced installation time. This concept also reduces the installation costs as only a single cable is used between antenna and display unit. The system has a short start-up time (less than 2 minutes). Maintenance is not required, making it less expensive to maintain than a standard gyro system.
The GPS compass allows calculation of distance and bearing between any two points, supporting Rhumb Lines (RL) for the short legs and Great Circle (GC) for long distance legs. Also, a trip log function comes standard for distance and heading.
The JLR-21/31 has CCRP function incorporated, allowing the transfer of CCRP sentences to other onboard equipment and anchor watch alerts the watch officer of possible anchor dragging situations.
The new trend graph display mode shows a history of roll, pitch and heave and SOG as an easy-to-read graphical view. Selections can be made to show maximum or average results.
The new GPS compass integrates 5 independent working NMEA output ports, which allows for connection to a wide range of onboard navigation equipment, such as radar, plotter, autopilot, sonar or other navigation devices.
