Discover how to integrate and optimize your Simrad autopilot system with your chartplotter for precise navigation and effortless control.

Autopilot Integration & Control Using Simrad

How to Pair, Calibrate, and Optimize Your Simrad System

Modern boating is all about precision, safety, and ease—and that’s where Simrad autopilot systems excel. Whether you’re running a Simrad AP44 Autopilot Controller, NAC-2/NAC-3 Autopilot Computer, NSX Chartplotter/Fishfinders or a NSS Chartplotter, seamless integration ensures smoother steering, better efficiency, and hands-free confidence on open water.

1. Pairing Simrad Autopilot with Your Chartplotter

Simrad autopilots connect effortlessly via NMEA 2000 or SimNet networks.

To integrate:

  • Ensure all devices (chartplotter, NAC computer, rudder sensor, and controller) are on the same NMEA 2000 backbone.
  • Power up your system and access Settings → Autopilot → Commissioning on your Simrad GO, NSS evo3, or NSX display.
  • Select “Find Autopilot Computer” to pair automatically.

This quick pairing allows your chartplotter to display and control heading, route tracking, and navigation data directly.

2. Setting Up Steering Modes

Simrad offers flexible steering options for every type of vessel:

  • Auto Mode: Maintains a set heading automatically.
  • NoDrift Mode: Combines GPS course tracking to hold a fixed path over ground.
  • Nav Mode: Follows routes created on your chartplotter.
  • Wind Mode (for sailboats): Keeps a constant wind angle for efficient sailing.

These modes can be easily adjusted through an AP44 Controller or touchscreen chartplotter interface.

3. Tuning PID Parameters for Precision

To fine-tune steering responsiveness:

  • Access Autopilot Settings → Rudder Gain / Counter Rudder / Autotrim.
  • Adjust Rudder Gain for quicker turns or smoother corrections.
  • Use Counter Rudder to control overshoot when changing heading.
  • Set Auto Trim to help your system learn your vessel’s steering behavior over time.

Fine PID tuning can greatly improve handling, especially for larger or heavy-displacement boats.
