GPS position information into Loran-C TDs—while you navi-
gate with GPS or DGPS.

precipitation static
Precipitation-induced electrical charge that can build up on
antenna surfaces, creating poor radio reception. Also known as
P-Static.
queueing waypoints
The process of specifying a trip one or more waypoints in
advance—as you’re navigating.
radar
A device or system that emits radio waves for navigational
purposes.
radar plotter

nected path to and/or from specific locations. In its simplest
form, a route can be a straight line to a single waypoint.
