Simrad A2004 Autopilot Controller

Simrad A2004 Autopilot Controller

Professional autopilot controller with 4.1-inch colour display, rotary control dial, and customisable work mode

  • Overview

    Proven Simrad Interface

    The A2004 builds upon the proven user interface and keypad layout of the Simrad AP70 and AP80 professional autopilot controllers, and delivers consistency with the latest generation of Simrad radar, sonar, and ECDIS displays. A large aluminium rotary control dial enables quick but precise steering adjustments, while dedicated keys offer instant access to steering modes, a custom-configurable Work mode, and automated turn patterns. All built-in controls are designed for ease of use with wet or gloved hands, in commercial settings such as fishing vessels and workboats. The A2004 also supports a wide range of Simrad autopilot remotes and steering levers.


    Continuum Steering Technology

    Every Simrad steering innovation builds upon a legacy encompassing over sixty years of autopilot development, which continues to this day. This legacy is exemplified by the Continuum algorithm: the software behind Simrad steering technology. Continuum steering distils years of research and on-water testing into a flexible software solution, capable of delivering reliable auto-steering performance tuned specifically to match a vessel’s control characteristics. With a comprehensive range of hardware and interface modules, Simrad autopilot solutions can be tailored to suit a wide range of commercial vessels and applications.


    Optically Bonded 4.1-inch Colour Display

    To ensure optimal visibility in all conditions, the A2004’s colour LCD panel is optically bonded to its protective glass covering – eliminating the possibility of internal condensation. Transflective LCD technology makes use of reflected sunlight to brighten rather than obscure the screen, delivering superior day-time visibility and lower power consumption compared to traditional backlit displays. An ultra-wide 170 degree viewing angle means key autopilot information is clearly visible at a glance, from anywhere in sight of the display.


    Thruster Integration & Rudder Feedback Support

    The A2004 enables autopilot control of a single thruster via an optional AD80 or SD80 interface module. The thruster can be set to engage automatically below a user-defined speed threshold, and configured separately for normal and Work modes. The A2004 also supports specialized heavy-duty rudder feedback units designed for reliable operation aboard commercial vessels.


    Configurable Work Mode and Low/High Speed Modes

    Autopilot settings can be tuned for optimal performance in separate low-speed, high-speed, and Work modes. The user-configurable Work mode allows the autopilot system to be configured for optimal response in a specific situation, such as a fully laden vessel.


    No Drift Steering

    No Drift mode integrates GPS navigation with auto-steering, using position data to counteract the effects of wind and tide. This allows the A2004 to maintain a straight track over ground on the current heading, without the need to manually set a waypoint or route. No Drift steering is available with an NMEA 2000® connected GPS receiver or compatible Simrad chartplotter.


    Flush or Bracket Mounting Options

    The A2004 supports flush-mount installation, or bracket mounting via the included gimbal bracket. An optional sun cover is available for external installations.
