The AN/ARN-147(V) is a compact and lightweight VOR/ILS/GS/MB (VHF Omni Ranging/Instrument Landing System/Glideslope/Marker Beacon) receiver system that is a US Air Force standard and has been incorporated into a variety of leading military fixed-wing and rotary aircraft, including C-130 Hercules, UH-1N Huey, and CH-47 Chinook.
The proven solid-state militarized VHF navigation receiver is MIL-E-5400 class II qualified and features optional internal MIL-STD-1553B capability, and is designed to provide superior performance in the most challenging of military aircraft environments. It features selectable helicopter rotor modulation suppression and also offers FM broadcast immunity to meet ICAO Annex 10 requirements, with an FM immunity retrofit kit available for noncompliant platforms.
The AN/ARN-147(V) is available in analog or analog/digital receiver versions, and the analog version can be easily upgraded to MIL-STD-1553B via a field-installable electronic card. The system is highly reliable, with a predicted MTBF of 7700 hours.
