♦
ALT = Altitude
Altitude of GPS Antenna on the medium sea level.
♦
Alter = Alternate Solution (TD Coordinates System)
Parameter selected by the user that is applicated in the conversion of TD
values to geographical coordinates Lat/Lon. It defines which of the two possi-
ble solutions can be used.
♦
Arrival Time
The estimated time of day you will reach your destination, based on your
current Speed and Track from GPS.
♦
ASF = Additional Secondary phase Factor (TD Coordinates System)
Correction to TD values which can be inserted by the user.
♦
Azimuth
The angular measurement from the horizon to a satellite or another object.
♦
AWD = Apparent Wind Direction
The Direction from which the Wind appears to blow relative to a moving point
(also called Relative Wind Direction).
♦
AWS = Apparent Wind Speed
The Speed at which the Wind appears to blow relative to a moving point (also
called Relative Wind Speed).
♦
Beacon
A prominent, specially constructed object forming a conspicuous vertical mark
as a fixed aid to navigation.
♦
Bearings
To select either degrees magnetic or degrees true. If magnetic readings are
selected the variation is computed automatically for every zone as soon as the
chart is displayed.
♦
Buoy

♦
Buoys and Beacons
Buoys and Beacons are used to indicate to mariners recommended or estab-

BRG = Bearing
It is the angle between the North (True or Magnetic) and a destination.The
horizontal direction of one terrestrial point from another referring to the North
(True or Magnetic). It is often used to indicate the direction to follow to reach
the destination.
♦
Chain (Loran-C GRI)
The Loran chains are groups of transmitting stations that use timed radio
pulse transmissions. In each of these chains there is a master station and two
or more slave or secondary stations. Stations belonging to a same chain transmit
pulses in timing groups: a different time base identifies each chain. The time
base of each chain is the Group Repetition Interval or GRI. This GRI identifies
the chain in unique mode. For example the GRI = 4990 identifies the chain of
Central Pacific zone.
♦
COG = Course Over Ground
Direction of the path over ground actually followed by a vessel.
