ALT = Altitude
♦
Altitude of GPS Antenna on the medium sea level.
Alter = Alternate Solution (TD Coordinates System)
♦
Parameter selected by the user that is applied in the conversion of TD values
to geographical coordinates Lat/Lon. It defines which of the two possible solu-
tions can be used.

Arrival Time

♦
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
♦
Angular measurement from the horizon to a satellite or another object.
AWD = Apparent Wind Direction
♦
Direction from which the Wind appears to blow relative to a moving point (also
called Relative Wind Direction).
AWS = Apparent Wind Speed
♦
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.
Boost Pressure
♦
Boost pressure in boosted engine.
Buoy
♦
Floating object moored to the sea bottom in a particular (charted) place, as an
aid to navigation.
Buoys and Beacons
♦
Used to indicate to mariners recommended or established routes, underwater
dangers, restrictions and regulations.
BRG = Bearing
♦
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.
CAN (Controller Area Network)
♦
Standardized interface for engine data. CAN SAE J1939 is used.
Chain (Loran-C GRI)
♦
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.
