Features:

  • This station can be operated as a part of ARC-POM2 and ARC-POM1 Multi-Station Localization Systems
  • The Station includes manual direction finding equipment or handheld automatic radio monitoring and direction finding devices providing for localization of emitters in places unreacheable for the mobile equipment: in the buildings, on the roofs, in difficult terrain
  • The data exchange and control are ensured through a LAN between all station posts
  • The software enables effective operation in a rapidly fluctuating radio environment.

The Station Provides:

  • New emitters search, estimation and comparison against the database
  • Automatic position finding and e-mapping of emitters both in real time and in postprocessing mode
  • Panoramic analysis within the entire operating frequency range or within separate intervals under complicated electromagnetic conditions, detection of its changes
  • Recording the 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
  • Database maintenance
  • Single and multi-channel direction finding of radio signals with random modulation types and spectrum width
  • Automated radiophonic channel monitoring 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
  • Demodulated signals playback
  • Accumulation of data for further analysis in the postprocessing mode
  • Station coordinate and course finding, showing station path in the map both in real-time mode and postprocessing mode
  • Field strength estimation and its distribution mapping
  • Showing emitters in spatially distributed locations
  • Evaluation of field strength distribution around emitters subject to terrain and field strength in the map
  • Mapping field strength distribution calculated based on measurement results
  • Localization of emitters based on field strength measurement
  • Verification of emitter parameters.

Station Post Functions

Post No. 1:

  • Single-channel and multi-channel direction finding
  • Search for new emitters
  • Panoramic analysis within operating frequency range
  • Radio environment recording within a specified frequency range based on amplitude/frequency/bearing/time coordinates
  • Recording radio signals, their technical analysis and parameter estimation
  • Automated monitoring of detected radio channels
  • Sending operational information through a LAN to the other posts for further entry to the database
  • Collecting and processing of radio channel monitoring data
  • Tasks/data transmission to slave stations
  • Data acquisition from slave stations
  • Database management (archivation, recovery, filtering, etc.)
  • Report (incl. graphical report) generation and printout
  • Data acquisition from the navigation equipment.

Post No. 1 is primarily intended for single-channel and multi-channel direction finding. If the number of posts is limited (e.g. when posts No.2-4 are not available) their tasks can be partially handled using just post No. 1.

Post No. 2:

  • Panoramic analysis within operating frequency range
  • Search for new emitters
  • Field strength evaluation
  • Sending operational information through a LAN to the other posts for its further entry to the database and task setting
  • Recording of the radio environment within a specified frequency range based on amplitude/frequency/time coordinates
  • Recording radio signals, their technical analysis and parameter estimation
  • Automated monitoring of detected radio channels.

Post No. 2 is primarily intended for detection of new emitters. When a new emission is detected, this post generates top priority commands and sends them to post No 1 (detection finding) and post No. 3 (multi-channel control). Post No. 2 has no limitations on task/mode changing.

Post No. 3:

  • Panoramic analysis
  • Radio signal spectrum displaying, calculation of spectrum, level and band of received signals
  • Tuning for the set frequency
  • Demodulated signal listening
