In complete configuration the station provides simultaneously for direction finding and technical analysis. Configuration of mobile station can vary depending of the purposes. Local network of the Station provides for interchange of service data (including tasks and results of radio monitoring) between its workstations. Structural diagram of station in complete configuration is given below.

  • Standalone operation at stops and while moving
  • Joint operation of several stations, including being a part of automated spectrum monitoring systems (ARMADA, AREAL, etc.)
  • To prevent digital path overloading of the equipment with simultaneous bandwidth of 24 MHz (ARTIKUL-M, ARGAMAK-CS) in complicated electromagnetic environment, digital radio receiver includes additional analogue path with 500 kHz bandwidth.

Station provides:

  • New radio emission search, evaluation and comparison against the database
  • Automatic position finding and e-mapping of emitters both in real time and in postprocessing mode.
  • Panoramic spectrum analysis within the entire operating frequency range or within separate intervals under complex electromagnetic conditions, detection of its changes
  • Recording radio environment within a specified frequency range. This procedure can function within a long period and is based on amplitude/frequency/bearing/time coordinates, unit location and the absolute time at the time of saving
  • Databases maintenance.
  • Single- and multi-channel direction finding of radio signals with any modulation types and spectrum width
  • Automated monitoring of open radiophonic channel within specific range sections and/or fixed frequencies, simultaneous recording of demodulated signals and their service parameters.
  • Recording and technical analysis of radio signals in real time mode and in postprocessing mode.
  • Check of frequency/time parameters and service information of base station of modern communication and data transmission systems (GSM, IS-95, cdma2000, EV-DO, UMTS, TETRA, DECT, LTE, Wi-Fi, WiMAX, DMR, APCO P25)
  • Demodulated signals playback
  • Accumulation of data for further analysis in the postprocessing mode
  • Station coordinate and course finding, display station path in the map both in real-time mode and postprocessing mode.
  • Showing emitters in spatially distributed locations
  • Localization of emitters based on signal level evaluzation
  • Verification of emitter parameters
  • Interchange of tasks and data with other stations (when joint operation within a system)
  • Creating and printout of reports
  • Database management (archivation, recovery, filtering, etc.).
