2.003.013 ARK-15M

2.003.013 receiver unit in the ARK-15M system

2.003.013 is a receiver unit used as a main electronic component of the ARK-15M automatic radio compass system. The unit receives, amplifies and processes radio signals from ground-based transmitters for airborne navigation. It works within the aircraft radio navigation system and supports direction finding and radio reception functions. The receiver is not used as a standalone navigation instrument; it operates together with antennas, control panels, matching units and cockpit indicators that form the complete ARK-15M radio compass system.

Radio signal reception through 2.003.013

The 2.003.013 receiver processes signals received from loop and non-directional antennas. These signals are converted into electrical information suitable for direction finding and navigation data generation within the radio compass architecture. In compass mode, the system determines the bearing to a radio station and supports navigation by relative bearing. In antenna mode, the system can be used for radio reception. Stable operation of the receiver depends on antenna condition, correct frequency setting, power supply, matching equipment and the condition of associated indicators and control panels.

2.003.013 in airborne radio navigation

The 2.003.013 receiver unit is part of an airborne automatic radio compass system used for navigation by ground-based radio beacons and transmitters. The receiver covers the low-frequency and medium-frequency range used by non-directional beacon navigation. It supports bearing determination and signal reception within the ARK-15M system. Since radio compass performance depends on both the receiver and aircraft installation, troubleshooting should include the antenna unit, matching unit, cabling, control panel, indicators, power supply and aircraft grounding condition, not only the receiver block itself.

Aircraft application of 2.003.013

The 2.003.013 unit is used on aircraft and helicopters equipped with the ARK-15M automatic radio compass. Application references include Mi-8 helicopters, Tu-134, Tu-154, Il-76, MiG-23, Su-24 and other aircraft types, depending on installed avionics configuration and documentation. Because radio navigation equipment may differ by aircraft modification, overhaul history and modernization status, applicability should be confirmed through the aircraft equipment list, wiring documentation and maintenance manual before ordering or installation.

System integration of 2.003.013 with ARK-15M components

The 2.003.013 receiver works with other ARK-15M system components, including the antenna unit 2.090.020, control panel 3.624.049 and matching unit 2.240.000. These components allow the system to receive radio signals, select operating mode, set frequency and transmit bearing information to cockpit indication equipment. The receiver uses a transistor-based modular architecture with integrated circuits. This design supports maintainability at block level and allows the unit to be checked as part of the complete radio compass system during avionics maintenance.

Identification and ordering of 2.003.013

Before ordering 2.003.013, the aircraft type, installed radio compass version, required condition and documentation set should be confirmed. The unit may be required for operational replacement, avionics repair stock or restoration of the ARK-15M navigation system. For correct supply, it is useful to specify the full designation, system name, compatible aircraft, passport availability, test records and whether associated ARK-15M components are also required. Since receiver performance is tied to calibration and system integration, serviceability documentation is important for acceptance.
