Radio Direction Finding (RDF)
Filtered Mode
Bearing History (grey pie shape) is
displayed and shows full range of
direction of RDF signals received
during the last 15 seconds. Average
Bearing (red bar) is displayed and
represents calculated average
direction of signals received over
the last 15 seconds. The wider the
Bearing History slice, the more multi-
path reflections you are receiving,
and the less you should trust the
bearing.
Radio Direction Finding (RDF)
Raw Mode
Bearing History (grey pie shape) is
displayed along with Average
Bearing (bar) and Instantaneous
Bearing (blue arrow) which now
represents the direction of each
RDF signal received. In low
multipath environments the blue
arrow offers the most responsive
display of the data. This is useful in
determining if a target has made a
sudden change of direction.

RDF and Global Positioning
System (GPS) Mode
Bearing History (grey pie shape) is
displayed along with Average
Bearing (bar) and Instantaneous
Bearing (arrow). The bar still repre-
sents the RDF average bearings, but
the arrow now represents the
absolute bearing to a received GPS
coordinate of the beacon. The arrow
and the bar alternate colors from red
(preferred) to yellow (less accurate)
depending on the quality of informa-
tion for either RDF or GPS.
