Navitron NT888G MK2 Adaptive Autopilot

System Overview & Engineering Architecture

The Navitron NT888G MK2 Adaptive Autopilot is a fully Type Approved installation programmable Adaptive Autopilot designed and developed by Navitron Systems Limited for professional use on Magnetic and/or Gyro based commercial vessels of all types – including High Speed Craft. The NT888G MK2 is a speed adaptive Autopilot which constantly monitors and self-tunes to provide optimum steering performance.

The system is built around a robust control architecture that integrates magnetic and gyroscopic heading inputs with adaptive algorithms to deliver precise steering. The NT888G MK2 Autopilot offers traditional Navitron reliability reinforced by Adaptive control technology, making it suitable for a wide range of vessel types from conventional cargo vessels to high speed passenger ferries underway at 50 knots.

Core Features & Operational Advantages

Adaptive Self-Tuning Control

The NT888G MK2 Adaptive Autopilot features an adaptive self-tuning algorithm that constantly evaluates and updates internal Autopilot Control Parameters. This adaptive mode is designed to provide optimum steering performance across the widest range of vessel types and operating conditions. The system is made possible by an adaptive self-tuning algorithm which is aided by external speed and draft inputs.

Multi-Waypoint Steering

The NT888G MK2 accepts track data for single leg or multi waypoint steering performance. When derived from an Approved ECDIS/Plotter configuration, the system will promote NT888G MK2 controlled constant radius turns and/or complex route manoeuvres as instructed. This capability makes the autopilot ideal for vessels requiring precise route planning and complex manoeuvres.

Programmable Control Features

The NT888G MK2 Autopilot offers traditional Navitron reliability reinforced by Adaptive control technology. Standard features include:

Programmable Turns: RAD / ROT, Next Course & U Turn
Automatic Stability: Compensates for Rudder speed variations
Heading / VDR Output Data: NMEA, Step by Step and Furuno Heading, $XXHTD, $XXRSA VDR formats
Programmable Limits: Radius and Rate of Turn, Off Course, Course Comparator and Watch Alarm Levels plus Rudder Limit
Dedicated Next Course and U Turn key functions

NMEA & Pulse Speed Inputs

The system accepts 4 – 20mA Draft Input for Bowthruster & Rudder Control. Speed inputs are provided via NMEA and Pulse signals, enabling the adaptive algorithm to adjust steering parameters in real time.

4 Mag/Gyro Heading Inputs

The NT888G MK2 accepts 4 Mag/Gyro Heading Inputs including:

Sensor Coil

2 x NMEA

1 x StepTrack Steer

NMEA & Step-by-Step Heading Data

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

4.3″ Colour Display

All operational data is shown on the Control Unit 4.3″ colour display which features operator variable backlight illumination and is installation selectable for positive or negative mode character presentation.

Multiple Control Units

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.

Compatibility

The NT888G MK2 is immediately compatible 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.

Standard Supply Voltage

Standard NT888G MK2 supply voltage range is 11-40Vdc. Optional equipment includes Power Steer Controls, Analogue/Digital Heading Repeaters and Rudder Angle Indicators.
