Computers: the brain of your autopilot

The autopilot computer is the central unit that processes sensor data and controls the steering system. Choosing the right computer is crucial for your autopilot's performance and reliability, especially in challenging conditions. At Skysat, drawing on our extensive experience in offshore racing, we guide you toward the model best suited to your boat and your needs.

how to choose the right pilot computer

Choosing an autopilot computer depends on several factors, including the size of the boat, the type of navigation, and the desired communication interfaces. An oversized computer isn't necessarily an advantage, but an undersized model will limit your autopilot's performance.

• Raymarine ACU (Actuator Control Unit): A complete range for hydraulic and mechanical cylinders, incorporating AST (Advanced Steering Technology) for optimal performance. SeaTalk NG and NMEA 2000 compatible.
• B&G H5000 CPU: High-performance computer for demanding navigators. Advanced control algorithms, Ethernet interfaces, and compatibility with B&G sensors. Requires expert configuration.
• Garmin Reactor 40: Computer compatible with hydraulic and mechanical systems. Shadow Drive technology for easy manual override. NMEA 2000 integration.

the computer's interfaces and connectivity

Connectivity is a crucial aspect to consider. The computer must be able to communicate with other onboard instruments, such as the GPS, compass, and wind sensors. NMEA 2000 and SeaTalk NG protocols are the most common, allowing for seamless integration.

• NMEA 2000: Standard communication protocol for navigation instruments. Enables data exchange between different devices.
• SeaTalk NG: Raymarine's proprietary communication protocol, compatible with NMEA 2000 via converters.
• Ethernet: Some high-end computers offer Ethernet connectivity for faster communication and integration with advanced navigation systems.

💡 Skysat's advice

Before choosing your control unit, check its compatibility with your existing rudder angle sensor. A mismatch can lead to piloting errors and damage the system.
