Amplitude-digital direction finder

The direction finder is designed for conducting radio monitoring in the range from 9 kHz to 9(30) GHz and for high-speed direction finding and determining the direction to detected radiation sources in the range of 600 MHz-9000 MHz.

Competitive advantages

Direction finding is performed not only according to the principle of a classical amplitude direction finder, but also on
the basis of proprietary algorithms that allow direction finding of digital radio signals of various communication standards. Both noise-like broadband (CDMA, WCDMA, UWB), and having time slots and modulation types FSK, QPSK, OFDM.


When direction finding of cellular signal sources is carried out direction finding with the allocation of unique identifiers
of base stations (MCC, MNS, Lac Ci, etc.) This allows you to accurately indicate the direction to the base station of interest,even if several base stations are operating at this frequency from different directions.

  • The ability to search for the presence of signals in non-standard sections of the radio bands. This allows you to identify unique UAVs with unknown parameters of transmitters.

  • Direction finding of 2G(GSM), 3G(UMTS), 4G(LTE) base stations.

  • It is possible to connect a manual direction finding system.

  • Working in a single system of several direction finders allows you to determine not only the direction, but also the point of location with the display on the electronic map.
