2.003.013-01 ARK-15M

2.003.013-01 receiver unit in the ARK-15M system

2.003.013-01 is a receiver unit used as one of the main electronic elements of the ARK-15M automatic radio compass system. The unit is intended for reception, amplification and processing of radio signals from ground-based transmitters. It converts received signals into information used to determine the relative bearing to a radio station and transmit navigation data to aircraft indicators. The -01 version identifies the receiver supplied as an assembly with frame, which is important for ordering, installation and replacement.

Signal processing through 2.003.013-01

The 2.003.013-01 receiver processes signals from loop and non-directional antennas. These antenna inputs are converted into electrical signals suitable for direction finding within the ARK-15M system. In compass operation, the system determines the course angle to a radio station and supports navigation by radio beacon. In antenna operation, the system supports reception mode. Stable receiver performance depends on the condition of the antenna unit, matching unit, control panel, aircraft wiring, power supply and related cockpit indication equipment.

2.003.013-01 as a receiver on frame

The 2.003.013-01 version differs from the base 2.003.013 designation by supply configuration. The -01 execution means the receiver is supplied in assembly with the frame, or “on frame”. This detail should be included in technical requests because it may affect installation readiness, mounting configuration and replacement scope. When ordering a replacement unit, it is useful to confirm whether the customer needs only the receiver block or the receiver installed on its frame according to the ARK-15M equipment configuration.

Aircraft application of 2.003.013-01

The 2.003.013-01 receiver is used in aircraft and helicopter navigation systems equipped with the ARK-15M automatic radio compass. Applicable platforms may include Mi-8 helicopters, Tu-134, Tu-154, Il-76, MiG-23, Su-24 and other aircraft types, depending on the installed avionics configuration and aircraft documentation. Since radio navigation equipment can differ by aircraft modification, overhaul history and modernization status, applicability should be confirmed through the aircraft equipment list, wiring documentation and maintenance manual.

System integration of 2.003.013-01 with ARK-15M components

The 2.003.013-01 unit operates as part of the ARK-15M system together with the antenna unit 2.090.020, control panel 3.624.049 and matching unit 2.240.000. These components provide antenna signal reception, frequency selection, operating mode control and bearing data output to aircraft indication systems. The receiver is built on a transistor-based modular architecture with integrated circuits. This block-level construction supports system maintenance and allows the receiver to be checked as part of the complete radio compass installation.

Identification and ordering of 2.003.013-01

Before ordering 2.003.013-01, the aircraft type, ARK-15M configuration, required condition and documentation set should be confirmed. It is especially important to specify that the required version is 2.003.013-01, since this identifies the receiver supplied with frame. The unit may be needed for operational replacement, avionics repair stock or restoration of the ARK-15M system. For acceptance, the buyer should clarify passport availability, test records, frame completeness, connector condition and whether associated ARK-15M components are also required.
