Heading
& Speed Data Interface
Type Selection |
Designed and developed by Navitron Systems Ltd to provide heading data/signal coupling between otherwise incompatible equipment, the Navitron Heading Data Interface range offers simple to install solutions to many heading data and speed log communication problems.Six models of Heading Data Interface (HDI) are available to convert heading signals sourced from proprietary types of gyro, magnetic and electronic compass - including GPS antenna types - to the signal format(s) required to 'handshake' with a wide range of end users such as Radars, Trackplotters, Autopilots, GPS Receivers and Heading Repeaters. Additionally, three of the models will accept speed log pulse information for conversion to combined NMEA heading and speed data output (VHW sentence) for use by ECDIS and AIS Systems etc. |
