The Simrad AP9 MK3 Autopilot is suitable for a wide range of vessels, tested and approved according to the latest IMO resolution. The AP9 MK3 autopilot is recognized as the most flexible and adaptable autopilot on the market place. The list below highlights a few of the features available in this sophisticated autopilot: As a retrofit model, the AP9 MK3 should be a first choice because of its ability to interface to almost any magnetic or gyrocompass, steering gear and navigation receiver. The possibility of adding a full function second station further emphasizes the capabilities built into AP9 MK3 autopilot system. The AP9 MK3 has been designed to produce very accurate steering under autopilot control. The autopilot has been programmed to learn how the rudder responds to commands. This both reduces rudder activity and ensures that the rudder is positioned exactly as required, so eliminating rudder overshoot. It also compensates for wear and play in the steering gear, which can be of particular importance when using AP9 MK3 as a retrofit autopilot. Precise course keeping is guaranteed by the ability to set all parameters on the AP9 MK3 individually with a high level of fine tuning. Special rate of turn functions ensure that all vessels, irrespective for their individual steering characteristics can achieve smooth course changes. The combination of touch buttons, LCD displays and the advanced electronic programming produces efficient operation. All mode selection and steering parameter settings are made using touch buttons and instruction is confirmed on the display. Course changes can be made by the traditional rotary course selector or using 2 push buttons. These produce an exact 1° course change (port/stbd). Vessel heading information is shown digitally, deviation from set course and confirmation of rudder commands are also displayed. As an optional feature, the AP9 MK3 can be configured to control a bow thruster. Rudders are inefficient at the slow speeds often required by fishing boats, dredgers and survey vessels. A vessel can, however, maintain an accurate heading by automatic control of a bow thruster through the AP9 MK3 autopilot. The AP9 MK3 can accept information from navigation receivers and plotters to combine steering and validation. In practical terms the autopilot uses constantly updated information to steer the vessel along a predetermined track. The autopilot maintains a straight line between waypoints, reducing or eliminating Cross track error (XTE), and reducing both time and fuel. Ships having navigation equipment with the ability to plan long distance routes (ECDIS) will benefit from fully automatic sailing.

Designed and developed by Navitron Systems Ltd for professional use on Magnetic and/or Gyro based vessels of all types – including High Speed Craft (HSC) – to approximately 3000 gross tones, the Navitron NT888G is a technologically advanced and powerfully equipped Autopilot which is clearly displayed and simple to operate. Equally at home in new build and retrofit applications over an exceptionally wide range (fishing vessels, tugs, dredgers, ferries, coasters, survey and support units etc.) the NT888G Autopilot offers traditional Navitron reliability reinforced by Adaptive control technology. The adaptive function automatically monitors and self tunes the Autopilot parameters to provide optimum steering performance whether operating on a fishing vessel in a low speed work mode or on a high speed passenger ferry underway at 50 knots. With a standard scope of supply comprising NT888G Control Unit suitable for foot bracket or panel mounting, robust Rudder Reference Unit and central Distribution Unit, the Autopilot System is immediately compatible with a wide range of vessel steering configurations including single and dual solenoid systems and voltage (±10Vdc) or current driven (4-20mA) Steering Amplifiers. Up to a maximum of 3 Control Units may be installed per system and each Control Unit is equally equipped with comprehensive displays of Actual Operating Mode, Heading, Rudder Angle, Rate of Turn and Speed Data which is enhanced by Track Steering graphics when the Track Mode is engaged. The display mode itself (light characters on a dark background or vice versa) is also installation selectable with operator adjustable red backlight illumination to suit individual preference. Track Mode operation provides single or multi waypoint steering performance based on data received from a proprietary ECDIS/Plotter including – when used in conjunction with an Approved ECDIS – remotely instructed constant radius turns etc. Other standard features provide “Next Course”, “U Turn” and permanent Heading changes in 1°/ 5°/10° steps etc. Standard outputs produce NMEA, Furuno and Step by Step heading data for Radar stabilisation etc. and optional equipment includes Power Steer Controls, Analogue / Digital Heading Repeaters and Rudder Indicators.

Designed and developed by Navitron Systems Ltd for commercially operated ocean going vessels of all types from typically 1800 gross registered tones upwards, the Navitron NT991G MK2 Autopilot is fully type approved to latest IMO and ISO standards. Available in various system configurations the NT991G MK2 can be supplied for immediate compatibility with most gyro compass and steering system types rendering it an extremely cost effective solution for new build and retrofit installations. Additionally, the NT991G MK2 Autopilot features automatic Waypoint Steering based on “Heading to Steer” serial data received from proprietary Track Plotters/ECDIS systems etc. ($HTC, $HSC, $APB sentences). Comprehensively intelligent, other standard features include Dual Mag and Gyro Heading Inputs, serial data outputs for Radar Stabilisation / Nav Computer / VDR use etc, fully Automatic Stability Compensation to accommodate Two Speed Rudder Systems and programmable Rate of Turn in degrees per minute. Simple to operate via a traditional and clearly marked rotary Course Setter, the NT991G MK2 is immediately compatible with existing Navitron equipment including Watch Alarms, Heading Repeaters, Rudder Angle Indicators and Power Steer Controls.
