The Garmin GHP Reactor Steer-by-Wire Corepack is a cutting-edge autopilot system designed for Volvo Penta Inboard Performance Systems (IPS) and stern drive joystick systems. Offering exceptional responsiveness and easy integration with powerboats and sailboats, this advanced system delivers commercial-grade technology for recreational boating. With a solid-state 9-axis Attitude Heading Reference System (AHRS) and minimal calibration, it's designed to give you a smooth, comfortable ride while minimizing power consumption and heading error.
Key Features
- Solid-State 9-Axis AHRS – The advanced 9-axis Attitude Heading Reference System (AHRS) minimizes heading error, course deviation, and rudder movement, ensuring a smooth and responsive autopilot experience. This solid-state technology allows for mounting flexibility, making installation quick and simple, even in various orientations.
- Minimized Power Consumption – The system is engineered to reduce energy use without compromising performance, offering efficient and sustainable operation for longer excursions on the water.
- Reacts to Conditions – Whether you’re facing choppy waters or rolling seas, the GHP Reactor’s ability to adapt to sea conditions helps it keep you on course. You can confidently trust the system to maintain your heading even during challenging conditions.
Versatile Operation for Powerboats and Sailboats
- Complete Autopilot Functions – The GHP Reactor comes with both powerboat and sailing features, including heading hold, wind hold, tack/jibe, step turns, and more. Whether you're cruising or racing, this system has everything you need to keep your boat on course.
- Smooth Control – The system automatically reacts to sea conditions for consistent, responsive steering, even when the boat is pitching or rolling.
Effortless Commissioning and Calibration

- Minimal Calibration Required – This autopilot system takes the hassle out of getting started with minimal calibration, offering a straightforward setup process.
Full Integration with Garmin Chartplotters
- Seamless Control – When connected with a Garmin networked chartplotter, the GHP Reactor offers full control of the autopilot from anywhere on the boat. This integration provides access to various features like Auto Guidance and trolling/search procedures for greater navigation ease.
- Auto Guidance – When paired with BlueChart® g2 Vision® charts (sold separately), you gain access to Auto Guidance, which automatically steers the boat along predefined GPS paths, making long journeys or tricky maneuvers even easier.
- MARPA and Chart Overlay – With MARPA (Mini-Automatic Radar Plotting Aid), the system can track up to 30 moving targets, and chart overlay ensures seamless navigation, improving situational awareness during your travels.
Networked Control and Flexibility
- Multiple Control Units – The GHP Reactor can be operated using up to 3 GHC™ helm control units, providing versatile control options throughout the boat.
- NMEA 2000® Network Integration – The system uses the NMEA 2000® network, allowing autopilot-heading data to be shared with other devices for better integration and data communication.
- Handheld Remote Control – For additional convenience, an optional handheld wireless remote control is available, allowing you to manage the autopilot system from any part of your vessel.
- Quatix® GPS Watch Integration – For the ultimate in convenience, you can control the GHC using the Garmin quatix®, the world’s first marine GPS navigation watch, which features ANT+® wireless technology for easy, hands-free control.
