Navitron NT-999G Autopilot

(the price includes VAT)

Purpose designed by Navitron Systems Limited for professional use on Magnetic and/or Gyro based commercial vessels of all types – including High Speed Craft – from approximately 3000 to 100,000 gross registered tonnes plus, the Navitron NT-999G is a speed adaptive Autopilot which constantly monitors and self tunes to provide optimum steering performance.
Powerfully equipped and technologically advanced, the NT999G is ‘wheelmarked’ in accordance with MED 96/98/EC and Fully Type Approved for conventional hull and High Speed Craft (HSC) to latest IMO and ISO specifications.

SKU: Navitron NT-999G Autopilot Category:

Description

Wheelmarked and type Approved to IMO A342(ix) as amended by MSC 64/67 Annex 3 & latest ISO specifications for Gyro based vessels from approx 3000 to 100,000 gross tonnes plus. Also includes RadioNav to accept Heading to Steer (HTS) data from ECDIS etc. for multi waypoint track steering.

Purpose designed by Navitron Systems Limited for professional use on Magnetic and/or Gyro based commercial vessels of all types – including High Speed Craft – from approximately 3000 to 100,000 gross registered tonnes plus, the Navitron NT-999G is a speed adaptive Autopilot which constantly monitors and self tunes to provide optimum steering performance.
Powerfully equipped and technologically advanced, the NT999G is ‘wheelmarked’ in accordance with MED 96/98/EC and Fully Type Approved for conventional hull and High Speed Craft (HSC) to latest IMO and ISO specifications.

Comprehensively custom programmable via a fully equipped but simple to use installation “Set Up” menu, the NT-999G Adaptive Autopilot may be set to work across the widest range of vessels to provide optimum steering performance whether operating on a conventional cargo vessel or tanker versus a high speed passenger ferry underway at 50 knots.
This is made possible by an adaptive self tuning algorithm which is aided by external speed and draft inputs.

Whilst the Adaptive nature of the NT-999G constantly evaluates and updates internal Autopilot Control Parameters, the Adaptive Mode may be switched off – if required – in favour of manually adjusted PID Control Settings via a built in “Controls” Menu.

Further facilities such as Radius and Rate of Turn, Off Course, Course Comparator and Watch Alarm Levels plus Rudder Limit are programmable via the built in “Limits” Menu.

Dedicated Next Course and U Turn key functions are also standard features.

Heading Input Data may be derived from ships Magnetic Compass in conjunction with a standard Navitron Heading Sensor Coil Type HSC2 and/or via three additional NMEA inputs which will accept Heading Data from Gyro or GPS Compass etc. A fifth (Step by Step) input is also available.

Track data for single leg or multi waypoint steering performance is also accepted and, when derived from an Approved ECDIS/Plotter configuration, will promote NT-999G controlled constant radius turns and/or complex route manoeuvres as instructed.

All operational data is shown on the Control Unit LCD display which features operator variable backlight illumination and is installation selectable for positive or negative mode character presentation.

Up to a maximum of 3 Control Units may be installed per system and each Control Unit is equally equipped with all control and display facilities which include Operating Mode, Heading, Course Set, Rudder Angle, Rate of Turn and Speed Data enhanced by Track Steering graphics when the Track Mode is engaged.

Standard scope of supply comprises NT-999G Control Unit suitable for foot bracket or panel mounting, robust Rudder Reference Unit and a central Distribution Unit which is equipped to interface with a wide range of steering system types including Single and Dual Solenoid arrangements (11-110Vdc/5A max), voltage (+/-10Vdc) and current (4-20mA) Steering Amplifier and Bowthruster configurations.

Heading Data outputs are available as standard in NMEA, Furuno and Step by Step (5V) formats for Radar stabilization purposes etc.

Standard NT-999G supply voltage range is 11-40Vdc and optional equipment includes Power Steer Controls, Analogue/Digital Heading Repeaters and Rudder Angle Indicators.
