Collins Aerospace Introduces Militarized VHF Navigation Receiver the Meets International Operability Requirements

Collins Aerospace introduces the AN/ARN-147(V) system which combines all VHF Omni Ranging/Instrument Landing System (VOR/ILS) functions into one compact, lightweight, low-cost set. It is the first militarized VHF navigation receiver with MIL-STD-1553B certification. The solid-state system is MIL-E-5400 class II qualified and meets international operability requirements by providing 50-kHz channel spacing for 160-VOR and 40-localizer/glideslope channels. This receiver system is recognized worldwide as a value-added solution on multiple military platforms. 

Originally designated as the standard VOR/ILS receiver for the United States Air Force, the An/ARN-147(V) quickly gained acceptance by many military users around the world and is installed on a multitude of platforms, including C-130, C-141, C-5, UH-1N, CH-47, UH-60, T-50 and JAS 39 Gripen.

The AN/ARN-147(V) is a proven design derived from extensive experience in navigation and precision approach and landing systems. As a leading supplier of these systems, Collins Aerospace has designed and manufactured more than 100,000 VHF navigation and landing systems. Solid-state modular design and rugged construction provide long life, high reliability and excellent maintainability for both new and retrofit applications on fixed and rotary-wing aircraft

The receiver combines all VOR/ILS functions in one compact, lightweight, low cost system. The AN/ARN-147(V) meets multiple stringent MIL-STD requirements, assuring peak performance under the harshest military aircraft environments. With support for both analog and digital (MIL-STD-1553B) interfaces, the AN/ ARN-147(V) is compatible with a variety of aircraft architectures. The AN/ARN-147(V) is available to meet FM broadcast immunity requirements as defined in ICAO Annex 10. Non compliant models can be upgraded with an FM immunity retrofit kit.

Key Features of the AN/ARN-147(V) VHF Omni Ranging/Instrument Landing System:

  • Low power, lightweight, solid-state design 
  • FM broadcast immunity per ICAO Annex 10 
  • Analog and MIL-STD-1553B interface 
  • MIL-E-5440 Class 2 environment 
  • MIL-STD-810 vibration 
  • MIL-STD-461/462 electromagnetic interface 
  • Selectable rotor modulation suppression
  • High reliability: Predicted mean time between failures is 7,700 hours
