15. APPENDIX: TERMS

ALT (Altitude) Shows the Altitude of the vessel.
APP Wind DIR SPD (Apparent Wind Direction) Shows the Apparent wind Direction when
a external wind instrument with NMEA is connected.
APP Wind SPD (Apparent Wind Speed) Shows the Apparent wind speed when a external
wind instrument with NMEA is connected.
BRG (Bearing) the direction from your current position to a destination point.
COG (Course Over Ground) – the course your vessel is heading
DATE Shows the current date received by the GPS.
DEPTH shows the water depth when the optional Black Box Fish Finder or Digital Depth
Sounder is connected.
DRAUGHT Tide height value referred to Horizontal cursor.
DSC (Digital Selective Calling) Digital Selective Calling is a semi-automated method of
establishing a VHF radio call. DSC had also been designated as part of the Global Maritime
Distress and Safety System (GMDSS). It is planned that DSC will eventually replace aural
watches on distress frequencies and will be used to announce routine and urgent maritime
safety information broadcasts.
DST (Distance) – the distance from your current position to a destination point.
ETA Estimated Time of Arrival
GPS Constellation The Global Positioning System (GPS) is a space-based radio-
navigation system consisting of a constellation of satellites and a network of ground stations
used for monitoring and control. A minimum of 24 GPS satellites orbit the Earth at an altitude
of approximately 11,000 miles providing users with accurate information on position,
velocity, and time anywhere in the world and in all weather conditions.
GPS2D The GPS is receiving at least 2 valid satellites
GPS3D the GPS is receiving at least 3 Satellites.
HDG (Heading) Shows heading from a External Flux Gate Compass when connected.
HDOP/VDOP Horizontal/Vertical Dilution of Precision. It is a parameter indicating the
precision of the positioning system (GPS). The smaller the HDOP/VDOP value, the more
accurately the position fix is provided.
HEIGHT The current tide height referred to the vertical cursor.
HIGH WATER The maximum level of the tide height in 24 hours.
