Appendix A-2 CA34/44/54 Glossary of terms
Navigation simulator
- the chartplotter function features a built-in navigation
simulator which can be used for demonstration purpose or for practicing ‘live’
navigation in ‘off season’.
Navigation to cursor or waypoint, in route or in track is started as described
in chapter 6. The navigation simulator is started via the interface setup: Press
[MENU], [7], [2], [PLOT]; under index tab ‘Position’ use the cursor to go to
‘Position mode’ and use the +/- keys to toggle to ‘Dead Reckoning’; then go to
‘Dead reckoning speed’ if you wish to change the current speed by entering a
new figure; press [ENT] to confirm.
The ship symbol will now ‘sail’ to the point of destination directly or via the
route you have selected and you can see how the alarms and automatic waypoint
shift all work, as if you were sailing yourself. You can also simulate making a
track trailing the ship or plotting eventmarks, etc. as the ship is ‘sailing’.
NMEA
– National Marine Electronics Association. The NMEA is an organi-
zation of manufacturers of marine electronics equipment. They have adopted
the NMEA0183 as a standard for communications between various types of
marine electronic equipment.

Position update - if, for some reason, there is no position update from GPS
or external sensor, the displayed position will start to flash and an alarm will
be activated to alert the operator. ‘Position missing’ alarm can be set ON/OFF
- see section 7.5. Reset the alarm by [CLR]. The displayed position will stop
flashing once normal position update is resumed.
Restart to approaching point
– will automatic recalculate the navigation data
from current position to approaching point.
Rhumbline
– is the straight line to a waypoint on a chart.
SDGPS
- Satellite Differential Global Positioning System - will provide posi-
tion corrections from received satellite signals (WAAS, EGNOS, and MSAS).
S peed – Speed Over Ground, indicated in knots, kilometers, or miles.
Starboard side – right (green).
TFT – Thin-Film Transistor (Active matrix) display.
UTC
– Universal Time Coordinates, which is equal to standard time in
London (GMT). UTC is not affected by the local summertime adjustments.
