Contact output signal, output in 1 pulse per nm.
Expressed in units of "p/nm".
Unit of ship speed.
Waves received from multiple directions due to reflection or refraction
of an initial wave by obstacles.
Abbreviation of National Marine Electrical Association 0183.
International standard for naval equipment transmission established
by the National Marine Electrical Association.
JRC radar supported format.
Medial rotation
Use of GPS or DGPS receiving functions to determine the current
position of a ship.
Abbreviation of Receiver Autonomous Integrity Monitoring. This
system automatically detects failed satellites and deselects their
positioning data from calculations. Including data from failed
satellites will result in a decrease in positioning accuracy; the RAIM
accuracy standard indicates the accuracy degradation base for
removal of failed satellites from positioning calculations.
Positioning with the use of SBAS satellite in addition to GPS satellite.
Same as ROT
GPS signal reception level.
Lateral rotation
Rate of Turn, the rate at which the ship turns, expressed by
"deg/min".
Serial data transmission standard. It is unbalanced, and hence can
only be used for short distance transmission.
Balanced serial transmission standard.
Abbreviation of Satellite-based Augmentation System. It is a blanket
term for wide scale GPS support systems using fixed position
satellites which send GPS error correction data over a wide range.
SBAS reception mode (manual / automatic).
Function for averaging over a specified number of seconds.
Speed Over Ground, This is the ship's relative speed to the ground.
Speed Through Water.
SBAS satellite test broadcast.
Abbreviation of Universal Time Coordinated. Successor to
Greenwich Standard Time.
