Description
Bottom Line Up Front (BLUF): Operational Overview
The Navitron Systems Systems Navitron NT991G MK2 Autopilot is a type-approved commercial marine navigation system engineered for high-reliability deep-sea and offshore vessel operations. Compliant with international IMO/SOLAS and IEC standards, the unit is fully supplied, bench-tested, and supported worldwide by Seanav Marine from our Dubai Maritime City (DMC) technical facility.
Navitron NT991G MK2 Autopilot designed and developed by Navitron Systems Ltd for commercially operated ocean going vessels of all types from typically 1800 gross registered tonnes upwards, it was developed and is approved to the 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 Stabilization / 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.
