PRE OWNED SPERRY MARINE NAVIPILOT AD SPERRY MARINE NAVIPILOT AD MARINE AUTOPILOT

The Sperry Marine NAVIPILOT AD2 is a sophisticated digital heading control system designed to provide maximum steering accuracy while minimizing fuel consumption. It features early adaptive technology that adjusts the autopilot's sensitivity to match the vessel's specific characteristics and sea state. This prevents the "hunting" of the rudder, which significantly reduces the mechanical wear on the steering gear and improves the vessel's overall speed and efficiency.

Known for its distinct digital display and tactile button layout, the AD2 is a modular system that can be configured for a wide variety of steering gear types. It is an IMO-approved system that has served as the backbone of bridge systems for thousands of cargo ships and tankers worldwide, prized for its ability to operate in extreme maritime conditions with minimal maintenance.

KEY FEATURES & APPLICATIONS

-- Adaptive Steering Control: Intelligent algorithms analyze vessel yaw and rudder response to optimize steering, preventing excessive rudder movement in heavy seas.

-- Dual Heading Monitoring: Capable of monitoring both a Gyro and a Magnetic compass simultaneously, providing an extra layer of safety through automatic comparison alarms.

-- Navigator (NAV) Mode: Interfaces with GPS or Loran-C receivers via NMEA 0183 to maintain a precise track over ground, compensating for cross-track errors caused by current or wind.

-- Rugged Modular Design: Built with high-quality industrial components that are easy to service, making it a favorite for long-term deployments in the commercial shipping industry.

-- Selectable Load Parameters: Allows the operator to switch between "Loaded" and "Ballast" settings to ensure the steering response matches the vessel's current displacement.

-- Emergency NFU Control: Integrated non-follow up steering capability ensures the bridge maintains control of the rudder even if the primary auto-steering circuit fails.

TYPICAL CONDITION (USED/REFURBISHED)

Our refurbished NAVIPILOT AD2 units from the Alang yards are subject to a strict 10-point technical validation. We focus heavily on the health of the Processor PCB and the Relay Drive boards, ensuring all steering outputs are firing correctly. The front panel display and mode lamps are checked for brightness and clarity. Each system is calibrated against a gyro-simulator to ensure it handles NMEA and Step/Synchro heading data with 100% accuracy before leaving our Bhavnagar facility.
