NAVITRON SYSTEMS LTD NT921 MKII SMALL VESSEL AUTOPILOT Specifically designed for small professional vessel use (typically 11-20m LOA) the NT921 MKII Autopilot provides a powerful combination of steering system control and interface facilities based on an extremely intelligent Control Unit which is clearly marked and simple to operate. Accordingly, the NT921 MKII offers Navitron steering expertise in a robust and compact package which is purpose designed to communicate as efficiently with the radar and GPS as with the steering gear due to the incorporation of special features which include: - Model NT921 MKII (259 x 176 x 115mm) Straightforward operation is a key feature of the NT921 MKII thus operator controls are kept to a minimum and are clearly identified by control panel markings which are red backlit for night viewing via a variable intensity illumination control. A conventionally marked Course Setter provides simple course selection backed up by dedicated LCD displays of heading and rudder angle information which, combined with other indicators, provide permanent visual confirmation of Autopilot status and performance. When connected to receive Cross Track Error (CTE) or Heading Steer Command (HSC) data transmitted from a proprietary source (GPS, Track Plotter System etc) the RadioNav section may be engaged by simple switch operation (OFF/LO/HI) to 'track' steer between predetermined waypoints stored in the GPS / Trackplotter. Suitable for console or bracket mounting, the NT921 MKII Control Unit is intended for wheelhouse location and is immediately compatible with GPS compasses transmitting NMEA 0183 heading data in addition to being supplied complete with Heading Sensor Coil and Rudder Reference Unit for installation to solenoid hydraulic systems. All Navitron Autopilot Systems are covered by comprehensive warranty terms and incorporate the following features as standard: - NAVITRON SYSTEMS LTD (Registered in England No. 2607869) Osborn House, 25E Brockhampton Lane, Havant, Hampshire PO9 1JT TEL: (UK) 023 9249 8740 FAX: (UK) 023 9249 8783 (INT) +44 23 9249 8740 (INT) +44 23 9249 8783 E-mail: [email protected] Web: www.navitron.co.uk
