- Direction finding, recording, technical analysis and classification of signals used in modern communication systems and data transfer system in HF, VHF, UHF and SHF ranges, as well as localization of their emitters. The last function is provided when the direction finder is installed on an unmanned helicopter.
- Onboard equipment:
- Azimuth-elevation DF unit with two-channel digital radio receiver and antenna system
- Power supply unit with integrated battery, which can be powered from the carrier's on-board power network
- ARC-KN3 Navigation and Synchronization Unit
- Data transmission equipment.
- Ground equipment:
- Data transmission equipment.
- Control and display unit (portable PC)
- Software packages for radio monitoring, cartography and technical analysis.
ARTIKUL-V2 Direction Finder installed on Unmanned Helicopter
- Navigation equipment integrated with the antenna system allows evaluating coordinates, course, speed, bank and pitch of direction finder with or without GNSS signals
- Localization of radio emissions sources when sole operation with single-position method.
Direction Finder Provides:
- Search for radio emission, evaluation of their parameters
- Localization of radio emission sources by single and multi-position methodsbased on azimuth and elevation angle data
- Collecting the data for analysis in postprocessing mode, recording radio signals (IQ and radio environment with service parameters to the storage.
- Creation of databases, their extension and comparing of the recorded data with the references
- Postprocessing of collected data, including:
- Localization of the source and displaying its position in electronic map
- Technical analysis, determination of modulation type and measurement of radio signal parameters
- Decoding service information of digital communications network signals: GSM, UMTS, LTE, CDMA (IS-95, cdma2000, EV-DO), TETRA, DMR, dPMR, NXDN, APCO P25 etc.
- Search for satellite terminals with frequency range of 1610 - 1660.5 MHz
- Automatic classification of satellite terminals signals (identification of communication system standard), and localization with multiple-position methods.
