Route:
A route consists of start point, end point and in-between waypoints. A single
route is a kind of simple route only having start point and end point, in
another word it is a “Goto” route. Route can also be made up of several legs
from one waypoint reaching up to 20 other different waypoints.
SOG:
Speed over ground. The actual speed the E-trace is moving over the ground.
This may differ from airspeed or nautical speed due to such things as sea
conditions or head winds.
Speed:
The GPS receiver uses instantaneous speed to indicate practical moving
speed.
TRP:
Tracked route.
True North:
The direction of the North Pole from your current position. Magnetic
compasses are slightly incorrect due to effects of the Earth’s magnetic field
while GPS units are more accurate for magnetic influences.
Waypoint:
A permanently stored and named position in the E-trace’s memory.
XTE:
Cross-Track Error.
