7.8 Finding the location of a signal scource
(Indoor)
Direction Finding • Map • Loc. Mode
GPS reception is generally not possible within closed rooms. It is therefore
possible to use the compass to determine direction but the location cannot
be determined.
To localize signal sources in rooms despite this fact, the IDA-3106 allows
you to define the ground area of the room by means of four corners (A – D)
and to specify its orientation by its azimuth. Bearings are taken on the signal
source from the defined corners and are displayed relative to these
reference points. Points A through D can also be seen as measurement
positions in rooms with completely different geometries (e.g. a circular
room), so the actual shape of the room is unimportant.
