SNR = Signal to Noise Ratio
The ratio of the magnitude of a signal that of the noise (interference).
SOG = Speed Over Ground
A calculation of the rate of movement of the ship over the ground.
Speed
The current velocity at which you are travelling, relative to a ground location.
Speed Filter
Turns On/Off the Speed Filter. When it is On, you can filter the speed of the ship, to optimize it. The
default setting is Off.

Speed (Simulation)
Sets the value for speed in the Simulation mode. The default setting is 01.0 Kts.

Speed (Unit)
Sets the speed unit among Kts = knots, Mph = miles per hour e Kmh = kilometers per hour. The
default setting is Kts.

Static Navigation
Sets up a threshold for the speed. When the speed received from the positioning device is under that
threshold, the chart plotter displays zero. The default value is 0.0 Kts.

Step Unit (Track)
Choose Distance (Dist) - the chart plotter can store a fix when the distance from its last stored position
is greater than a defined distance; Time - the chart plotter can store a fix after a defined time; Auto - the
software decides when storing a position, on the basis of the straight or curved track. The default
setting is Time.

STR = Steering
The difference between COG and CTS. If COG is 25° and CTS is 30°, then STR is 5° Right.
Target
In order to tag on the chart the point, towards which the ship is Heading, you can use a special mark,
called Target. When the Target is placed, all navigation data are referred to this Target (see Par. 3.4,
4.1.1.4, 4.2.1.3, 4.2.2.3).
Inserting Target : place 'DEST'
Deleting Target (Basic Mode) : place cursor on 'CLEAR'
Deleting Target (Advanced Mode) : place cursor on 'ENTER' + 'DELETE' + 'ENTER'
TD = Time Difference
Loran-C positions are determined by precise timing of the intervals between reception of pulses trans-
mitted by pairs of stations in the selected chain. Between any two stations a ship must be located
somewhere along a line of possible positions where the measured Time Difference, TD, between ar-
rival of pulses from those stations would be observed. The TD is measured from the time of reception
of the master station signal to the time of reception of the slave station signal.
