- 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.
- Controller
Ground equipment:
- Data transmission equipment.
- Control and display unit (portable PC)
Software packages for radio monitoring, cartography and technical analysis: SMO-PPK, SMO-STA, SMO-KN, SMO-ASPD.

ARTIKUL-V1 Direction Finder installed on Compact Unmanned Helicopter

Integrated navigation equipment allows evaluating coordinates, course, speed, bank and pitch of direction finder with or without GNSS signals.
