RMS: Root Mean Square. The standard deviation of the error in the GPS location.
Route: A route is a desired path of travel created on a chart and consisting of two waypoints at least with a starting
waypoint, and ending waypoint.
S
SAR: Search And Rescue
Scale: the distance between two points on a map as they relate to the distance between those same points on the
earth.
SEA: Anti Clutter Sea, Radar term
Serial Number: It identifies the product (software) and proves the purchase act. It is requested by the Activation
Wizard or from our services when you have to call them .
Sighting line: The line that you sight along to take a bearing.
Site Code: The Site Code is a critical data with regard to the Activation. It is the query part during the activation
phase and identify user machine in a unique way.
Site Key: The Site Key is a critical data with regard to the Activation. It is the answer part of the activation process. It
is the "Activation Code".
Slope: When land deviates from the horizontal plane it has slope. On a topographic map, the closer the contour lines
are placed together, the greater the slope of the land being portrayed.
Software Key License Manager: allows you to manage your software key each time needed.
SOG: means Speed Over Ground, it is the actual fixed geographic speed of a vessel. It is essentially the Speed over
Water (SOW), plus the cumulative effect of wind and current.
SOW: Speed Over Water - the speed over water as reported by a NMEA 0183 compatible GPS attached to your
system. So it is the actual speed of the boat traveling.
T
TCP/IP: Abbreviation of Transmission Control Protocol, and pronounced as separate letters.TCP is one of the main
protocols in TCP/IP networks. Whereas the IP protocol dealsonly with packets, TCP enables two hosts to
establish a connection and exchange streamsof data. TCP guarantees delivery of data and also guarantees that
packets will bedelivered in the same order in which they were sent.
TCPA: is the abbreviation that means Time to Closest Point of Approach.
Temporary License: During a dongle failure, the software automatically generates a Temporary License.This
license allows the user to keep on using his software normally for a limited time while he is waiting for a dongle
replacement.The temporary license is renewable if the user contact the technical support.
Tif: Tagged image file format. One of the most widely supported file formats for storing bit-mapped images on
personal computers (both PCs and Macintosh computers).
Topography: relief of the land surface; the graphic portrayal of that relief in map form by the use of contour lines.
Track: An onscreen and/or logged record of a vessel's previous movements.
Troposphere: The portion of the atmosphere from the earth's surface to the stratosphere; that is, the lowest 10 to 20
kilometers of the atmosphere.
True north: the geographical North Pole.
TTG: Time To Go - The amount of time estimated until the vessel reaches an active waypoint, assuming no
intervening change in course or speed.
TWA: True Wind Angle
TWD: True Wind Direction - In order to overcome the effects of drift and wind, a vessel which is trying to reach a
given waypoint may not bear straight towards it. As a result, onboard wind direction measurements - the AWD -
may not be the same as the True Wind Direction (TWD).
TWS: True Wind Speed - When the vessel is in motion, onboard wind speed measurements - the AWS - will differ
from stationary measurements (TWS).
