Purpose designed by Navitron Systems Limited for professional use on Magnetic and/or Gyro based commercial vessels of all types to approximately 2000 gross registered tonnes, the Navitron NT951G is a powerfully equipped and technologically advanced Autopilot which is 'wheelmarked' in accordance with MED 96/98/EC and Fully Type Approved to latest IMO and ISO specifications.

Model NT951G: -

A fully Type Approved installation programmable Autopilot for Mag and/or Gyro based vessels from 18m to approximately 2000 gross registered tonnes.

Typical Applications: -

Fully programmable to provide optimum installation flexibility and final seagoing performance, the NT951G Autopilot is also simple to operate via a clearly defined 'push and rotate' Heading selector supplemented by +1°/-1° keys for fine course adjustment use when appropriate.

Programmable Rate of Turn (ROT) allows the maximum safe ROT to be stored in memory at installation and is operator variable during normal operation up to the maximum safe level stored.

The control unit is suitable for console or bracket mounting in bridge or wheelhouse locations. Standard system supply also comprises a Mag Heading Sensor Coil and Rudder Reference Unit for installation to low voltage solenoid operated (11-40Vdc / 5A max) hydraulic steering systems.

High voltage solenoids (110/220Vac/dc) can also be accommodated via the inclusion of an optional Universal Relay Box type NT920URB.

A second Mag input facility is provided to accept NMEA heading data from a proprietary source and dual Gyro input ports are standard to accept NMEA and/or 1:1 isolated Synchro heading data.

Where Step by Step, M-type or non 1:1 Synchro ratios are involved, a Fully Type Approved Gyro interface (type NT925HDI) is available. Similarly, fully Type Approved Analogue and Dual Steering Interfaces are available for Azimuth propulsion units and Dual rudder systems respectively. (See Interface types NT990ASI and NT990DSI)
