Navigating challenging waters demands equipment that stands up to constant exposure to salt, waves, and extreme conditions. The Simrad AC70 Course Computer steps in as a reliable backbone for professional autopilots like the AP70 and AP80 systems, delivering precise control over your vessel's steering. Engineered for rudders driven by reversible motors or non-isolated solenoids, this drive computer processes frequency-based rudder angle feedback to ensure steady, responsive performance on long hauls or in rough seas.
In the world of marine electronics, reliability isn't optional—it's essential. This course computer shines in high-stakes environments, from offshore fishing charters to supply vessels, by offering stable autopilot performance that reduces crew fatigue during extended voyages. Its compact design simplifies retrofits into existing AP70/AP80 systems, while the built-in safeguards against power surges protect your investment in harsh saltwater conditions.
Users report smoother rides with less rudder hunting, thanks to the optimized processing of rudder feedback signals. Pair it with Simrad's ecosystem, and you unlock layered automation: wind vane steering modes, route following, and adaptive gain adjustments that learn your boat's behavior over time.
Every AC70 package equips you with essentials for straightforward installation:
These components cut down wiring hassles, letting installers focus on calibration rather than fabrication.
Mount the unit in a dry, ventilated spot away from engine heat. During commissioning, zero in on rudder feedback calibration using your vessel's full lock-to-lock travel—this ensures the autopilot compensates accurately for your hull's hydrodynamics. For multi-station helms, leverage the NFU port to sync joysticks without signal conflicts. Regularly inspect connections for corrosion, a common culprit in marine setups, to sustain peak efficiency.
The AC70 works with rudders using reversible motors or non-isolated solenoids, paired with frequency-based rudder angle feedback sensors. It's ideal for hydraulic rams in professional autopilots.
Yes, it includes one NMEA 0183 (IEC 61162-1) RX/TX channel, compatible with protocols 61162-1, 2, and 3 for sharing data like GPS waypoints and wind angles with other instruments.
It operates on 12-24V DC power supplies, with a maximum current draw of 30 amps, making it versatile for various boat electrical systems.
Absolutely. The unit features a dedicated connection for NFU remote controls, enabling manual steering overrides from multiple stations.
Designed for the harshest marine environments, it's proven in professional applications like the AP70 and AP80 autopilots on workboats and larger crafts.
Included are a T-Connector, a 2-meter power network cable with terminator, and a 0.6-meter pigtail male connector for plug-and-play installation.
Frequency feedback provides real-time, high-resolution data on rudder position, reducing overshoot and improving course stability compared to analog potentiometers.
Out on the water, the gear you run could make all the difference. With our high-performance products proven in the harshest of environments, Simrad ® will get you there like no one else. We give you a comprehensive portfolio of precise and responsive technology for a complete experience.
