Navigating challenging waters demands precision you can trust, especially when every degree counts for safe docking, efficient routing, or overlaying radar on charts. The Furuno SC70 satellite compass delivers that reliability without the hassles of traditional magnetic systems. Drawing from proven commercial-grade engineering, it harnesses multi-GNSS technology to feed ultra-accurate heading data straight to your autopilot, radar, chart plotter, and more—elevating your entire navigation setup.
Whether you're handling a nimble sportfisher or a mid-sized workboat, this compass shines in dynamic conditions, providing not just direction but a full suite of motion data to make tight maneuvers intuitive and secure.
Unlike gyro or fluxgate compasses that suffer from magnetic interference or require constant calibration, the SC70 uses satellite signals for heading accuracy down to 0.4 degrees. This stability ensures your ARPA targets track flawlessly, sonar beams stay locked, and autopilot holds course through choppy seas.
Integrate it seamlessly via Ethernet into your NMEA 2000 or shipboard network, and access pitch/roll data in analog or digital formats to stabilize sonar heads or vessel attitude systems.
Picture this: You're approaching a busy marina at dusk, crosswinds pushing you off line. The SC70's precise bow/stern speeds and ROT data let your joystick control or thruster system respond instantly, making berthing as smooth as parallel parking on land. Or during offshore runs, its stable heading sharpens radar ARPA for collision avoidance, while COG/SOG optimizes your route against currents.
For anglers, the accurate heading enhances chart plotter overlays, pinpointing structure without drift errors. Commercial operators appreciate the retrofit ease—reuse cabling from older SC-series units with minimal adapters, saving time and downtime.
"In my experience with marine electronics, satellite compasses like the SC70 transform navigation from reactive to predictive, especially when paired with modern multifunction displays."
Mount the compact antenna high and clear of obstructions for optimal satellite views, connect the junction box to your network, and the display unit provides intuitive status at a glance. Its short startup and lack of gyroscope warm-up make it ideal for vessels that sit idle between trips.
Pro tip: Position the antenna away from radar domes to minimize any potential interference, ensuring the cleanest GNSS reception for year-round accuracy.
Note: Antenna cable sold separately to accommodate custom installations.
It achieves 0.4-degree heading accuracy using multi-GNSS satellites (GPS, GLONASS, Galileo) without magnetic interference, outperforming fluxgate or basic GPS units in dynamic conditions.
Yes, it's perfect for small to medium vessels needing precise heading for autopilots and chart plotters, with easy installation and low power draw.
It initializes in about 90 seconds after power-up, far faster than gyro compasses requiring long warm-ups.
Absolutely—provides 3-axis speeds (bow, stern, longitudinal), ROT, and precise heading to aid tight maneuvers and docking.
Yes, via Ethernet or compatible interfaces; it retrofits easily with older Furuno SC-series cabling using optional kits.
No—it's fully solid-state with no mechanical parts, eliminating recurring costs and servicing needs.
IMO type-approved as THD, GPS, and ROTI, compliant with IEC and ISO marine standards for professional use.
SC70 Satellite Compass w/o Cable
The SC70 is the latest satellite compass built on FURUNO’s commercial-grade technology platform. These satellite compasses prove their value by increasing the accuracy of other devices, such as Radar, ARPA, Scanning Sonar, Current Indicator, Chart Plotter, ECDIS and Autopilots. They provide a highly accurate heading input to these other technologies by utilizing the very latest GNSS (Global Navigation Satellite System). This satellite system is comprised of GPS, Galileo and GLONASS to ensure the highest precision and a continuous coverage.
The SC70 provides a variety of data, including GPS Positioning, SOG (Speed Over Ground), COG (Course Over Ground), ROT (Rate Of Turn) and 3-axis speed (bow, stern and longitudinal). All of these data assist with critical maneuvers, such as berthing. The compasses is maintenance free - a great asset for any vessel.
