Instrumental accuracy of direction finding using AFS №1:

• within the range of 1.5 - 5 MHz
3.0°
• within the range of 5 - 15 MHz
2.0°
• within the range of 15 - 30 MHz
1.0°
Instrumental accuracy of direction finding within the range 1.5 - 30 MHz using AFS No.2
4 – 6°
Accuracy of one-position estimation of IRI coordinates at single-hop track (up to 1500 km) and quiet ionosphere (AFS №1))
not worse than 20 % from range
Possibility of detection (direction finding) of signals with frequency hopping

Radio interception and recording of radio signals

Technical analysis of the received radio signals, including:

• search, detection and recording of radio signals in the systems with automatic link establishment ALE (2G standard)

• demodulation of radio signals generated according to standard MIL-STD-188-110B

• demodulation of radio signals with frequency manipulation and speed of manipulation up to 300 Bd

• measurement of basic parameters of radio signals (frequency band, signal/noise, speed of manipulation, central frequency)

Power supply system provides:

• possibility of connection and work of radio-electronic equipment of direction finder from an external network of power supply voltage 220 V 50 Hz by means of the network extension piece on the distance of about 50 m from the connection point

• continuous work of direction finder (minimum 24 hours) using independent power supply (220 V 50 Hz) and external network

Chassis:

OPM-8/1 direction finder is based on two specialized cross country vehicles KamAZ. Hardware compartments are equipped with life-support subsystems (air-condition, power supply, filter-unit with pressurization), safe vault for papers, rack for weapon storage
