Manpack Automatic Direction Finder

«Security & Quality» Gold Medal awarded by «National Security International Contest» (2011)


The direction finder is intended for search, detection, automatic direction finding and localization of radio emission sources. The direction finder can be operated at stops and while moving standalone or as a part of automated spectrum monitoring systems (ARMADA, AREAL etc.)

Typical Configuration:

  • ARGAMAK-2K Two-Channel Panoramic Radio Receiver
  • AS-HP1 Antenna System for automatic direction finding within 110 – 3000 MHz, with integrated navigation equipment
  • Control and display unit with SMO-PPK, SMO-STA, SMO-ASPD, SMO-KN Software Packages
  • Battery set, AC power supply, vehicle-based power supply and charger
  • Holder to secure control and display unit when operation in manpack mode
  • Frame used to mount equipment and place the antenna systems when operation in the manpack version
  • Backpack for accessories (frame-mounted)

  • AS-HP2 Antenna System for automatic direction finding within 3 – 8 GHz, with integrated navigation equipment
  • AS-HP5 Antenna System for automatic direction finding in 20 - 3000 MHz range (mobile and fixed operation modes), with integrated navigation equipment
  • AS-HP-HF Antenna System with digital panoramic radio receiver integrated navigation equipment for automatic direction finding in 1.5 - 3000 MHz range (mobile and fixed operation modes)
  • Vehicle luggage box with fasteners to mount DF antenna systems
  • Tripod (mast) for direction finding antenna system mounting when operated at temporary workstations
  • Broadband radio monitoring antennae
  • External ARC-KNV4M Frequency Down-Converter for radio monitoring and amplitude (manual) direction finding within the range 3 - 18 GHz
  • Rugged control unit based on PC
  • SMO-BS Software Packages for Wireless Data Communication System Analysis BS 3GPP (standards GSM, UMTS, LTE), BS CDMA (standards CDMA, EV-DO), BS TETRA, BS TRUNK (standards DMR, APCO P25), BS Wi-Fi.

Direction Finder Provides:

  • Single- and multi-channel automatic direction finding of RF emissions with any modulation type and spectrum width in 1.5 to 8000 MHz range (using replaceable antenna systems)
  • Manual direction finding within 3 – 18 GHz range (when ARC-KNV4M Down-Converter is available)
  • Displaying the emitter bearing and localization of detected emitter on the electronic map
  • Panoramic spectrum analysis within the entire operating frequency range or within separate intervals under complicated electromagnetic conditions, detection of changes in ambient electromagnetic conditions
  • Search for radio emission, measurement of their parameters
  • Creation of databases, their extension and comparing of the recorded data with the references in the database
  • Recording of radio signals to a storage device
  • Recording the radio environment to storage within a specified frequency range. This procedure can function within a long period and is based on amplitude/frequency/bearing/time coordinates, the station location and the absolute time at the time of saving
  • Accumulation of data for further analysis in the post-processing mode, simultaneous recording of demodulated signals and their service parameters (frequency, time, signal level, etc.)
  • Demodulated signals playback
  • Decoding of service parameters of communication systems (GSM, UMTS, LTE, IS-95, cdma2000, EV-DO, TETRA, DECT, DMR, APCO P25, Wi-Fi).
