Autopilot Core Pack

This pack includes the Simrad NAC-3 autopilot computer, RF25N rudder feedback unit, Precision-9 solid-state compass, plus all cabling and connectors required to build an NMEA 2000 network backbone or connect your autopilot system to an existing NMEA 2000 network. To create a complete Simrad Continuum autopilot system, just add a hydraulic pump or mechanical drive unit to suit your steering system, and choose a dedicated autopilot controller or Simrad multifunction display.

NAC-3 Autopilot Computer

The NAC-3 Autopilot Computer is recommended for boats above 10 metres (35 feet) in length. It is rated for high-current output of up to 30 amps continuous and 50 amps peak, plus a clutch output; this is suitable to operate high-current drive pumps including the Simrad RPU160 and RPU300, mechanical drives such as the Simrad DD15, hydraulic linear drives such as the HLD2000 series, and solenoid valves.

Multiple Control Options

Choose from a range of dedicated autopilot controllers, or control your autopilot from your existing multifunction display or glass bridge with full Simrad display integration. Install extra autopilot stations, ideal for dual-helm vessels, or add the Simrad WR10 wireless remote for instant steering and autopilot control from anywhere on board.

RF25N Rudder Feedback Unit

Rudder feedback units are sensors that connect to your rudder via a mechanical linkage and continuously report actual rudder position to your autopilot computer allowing the Simrad Continuum steering algorithm to make the best-informed steering decisions possible. These sensors are typically used on boats with inboard engines, on larger vessels, and in special applications where Virtual Rudder Feedback may not be suitable. The RF25N included in this pack connects directly to your boats NMEA 2000 network, simplifying the cabling required for installation.

Simrad Precision-9 Compass

The Precision-9 Compass supplies accurate heading and rate-of-turn information to your autopilot and other onboard systems over an NMEA 2000 connection. Heading is determined by an internal array of solid-state sensors that constantly measure motion and orientation on nine axes. The Precision-9's solid state technology is not only accurate and precise, but also exremely reliable with no internal moving parts. An easily adjustable mounting bracket and single-cable connection allow simple installation aboard any vessel, including up-mast mounting suitable for interference-free operation with steel hulls.

Automatic Tuning and Calibration

Auto-tuning simplifies setup and ensures optimal steering performance. Automatic compass calibration improves heading accuracy as you travel, using data gathered by the Simrad Precision-9s internal array of solid-state sensors.

Easy Installation

Industry-standard NMEA 2000 networking and NMEA 0183 input allow simple connectivity to sensors, autopilot controllers, and multifunction displays located anywhere on board.
