SH-60S-AOA extends the capability of the SH-60S-TC by adding the ability to triangulate the location
of an interferer on a map for signals between 9 kHz & 6 GHz.

Triangulation is one technique you may use to determine the location of an of an RF
emitter. The principle is to take three or more measurements from dierent locations,
with each measurement location being 80 to 100 degrees in azimuth away from the
location of the previous measurement. See below for an example of the triangulation
technique.
Due to reections of the emitter’s RF signal (multi-path) and the gain and directivity of
the antenna used with the SignalHawk, the exact location of the emitter may not be
pinpointed with the rst three measurements. However, the measurements will form a
triangle in the area of the emitter. Making additional measurements in the vicinity of the
triangle formed by the initial measurements, will help rene the location.
