Furuno Satellite Compass

Feb 25, 2020

Furuno introduced two new compact and easy-to-install Satellite Compasses, perfect for virtually any size boat. The SCX20 and SCX21 have raised the bar for multipath mitigation, accuracy, and reliability, thanks to what they are calling Baseline Target Architecture. The four-antenna array of the SCX20 and SCX21 Satellite Compasses are configured in a manner that creates six unique baselines from which to calculate accurate heading information, even in severe environments.

Satellite Compasses traditionally utilize a two- or three-antenna configuration that allows for a single baseline of data, which can present performance challenges on some vessels due to multipath interference caused by signal blockage. The multipath effect occurs when a Satellite Compass receives a signal from paths other than direct line of sight, such as when the view of satellites is obscured, or when the signal is reflected off of a bulkhead, mast, or other obstruction. The multipath phenomenon can significantly reduce the performance of Satellite Compasses and has been an ongoing issue for marine electronics installers. The compact size, flexible mounting capabilities, and unique four-antenna design of the SCX20 and SCX21 make them capable of calculating precise heading, pitch, roll, and heave information, even when line of sight is limited to only a single satellite. Having multiple baselines makes them the perfect heading solution for even the most challenging of vessel installations.

The SCX20 connects to the ship’s NMEA2000 backbone directly, while the SCX21 connects to onboard equipment via three fully configurable NMEA0183 ports. Furuno’s GP39 is a perfect display and controller for the SCX21. Both models provide accurate Time, Position, 1.0˚ Heading accuracy, COG/SOG, Roll/Pitch/Heave, ROT (10 degrees/second), 3-Axis Speed, and air temperature and pressure data. Their compact and rugged housing weighs only 2.2lbs (1kg), and pole mount kits are available to provide a simple installation on any vessel. This ground-breaking technology from Furuno provides the ultimate in stable, extremely reliable heading to enhance the accuracy of Furuno’s excellent Radar, Fish Finder, Sonar, Autopilot, and Navigation products.

NMMA Canada’s Day on the Hill event hits a new high in 2024


While the Day on the Hill lobby session has been a key activity for NMMA Canada for many years now, I feel that the event hit a new high in the 2024 session in Ottawa on May 27 and 28th.

Lead by Executive Director Marie-France MacKinnon and executed by her team and their public affairs firm, BlueSky Strategy Group, the results were impressive. The NMMA Canada Board of Directors were organized into teams with business interests and special skills matched up to politicians and senior bureaucrats to most effectively present the marine industry’s agenda of issues.

Even in the event of an onboard power failure, a Ritchie Navigation SuperSport Helmsman SS-1002 magnetic compass still works. Plus, when the vessel is moving slowly in fog or while trolling, it can do something a GPS can’t: show the actual heading in real time. As a back-up to modern electronics, it’s a vital navigational tool that belongs on every commercial and recreational boat.
