Purpose designed by Navitron Systems Limited for professionally operated ocean going commercial vessels of all types from typically 1800 to 20,000 gross registered tonnes, the Navitron NT991G MK2is 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. Also Russian Maritime Register of Shipping (RMRS) and Morsviazsputnik approved, multi waypoint track steer facilities are included for use with 'Heading to Steer' data received from ECDIS etc.
Fully programmable to provide optimum installation flexibility and final seagoing performance commensurate with the turn rates and inertia levels of larger vessels, the NT991G MK2 Autopilot is also simple to operate via a traditionally marked rotary Heading selector backed up by CANCEL and CONFIRM keys to preclude accidental course changes as required by Type Approval regulations.
Programmable Rate of Turn (ROT) allows the maximum safe ROT to be set by the operator and can be used in conjunction with automatic waypoint steering data received from ECDIS when operating in the 'track' mode.
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. An optional high voltage (110/220Vac/dc) is also available.
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.
