For decades, Rockwell Collins' navigation equipment has established a presence in history, paving the way for innovative technologies and systems for both commercial and military applications. Our airborne solutions cover a full range of radio navigation requirements.

TACAN
Rockwell Collins' Tactical Air Navigation  (TACAN) systems provide pilots with navigation information by computing range and bearing relative to a ground station or an airborne beacon system. When combined with an optional rotating antenna and control unit, TACAN systems will also compute range and bearing relative to an air-to-air TACAN beacon or Distance Measuring Equipment (DME)-only ground station. The TCN-500 (AN/ARN-153(V)) airborne receiver-transmitter (RT) supports the operational requirements of high performance aircraft in a lightweight, compact design and is equipped with both digital and analog interfaces. The TCN-550, based on the TCN-500, is the latest TACAN design incorporating a beacon mode and is compliant with the Software Considerations in Airborne Systems and Equipment Certification (DO-178B Level C). Both systems compute velocity and time-to-go information.

VOR/ILS
The Very High Frequency (VHF) Omni Ranging/Instrument Landing System (VOR/ILS) receiver provides the operator with complete navigation functionality without the need for independent backup control panels. The Rockwell Collins AN/ARN-147(V) is the U.S. Air Force's accepted VOR/ILS Receiver, and is being installed in all U.S. Air Force C-130, C-141, UH-1N and C-5 aircraft. The AN/ARN-147(V) system, consisting of a receiver, control and mount, combines all VOR/ILS functions - (VHF) omni-directional range, localizer, glideslope and marker beacon receivers - into one compact, lightweight unit.

Multi-Mode Receiver
The Rockwell Collins Multi-Mode Receiver (MMR) is a civil-certified, commercial-off-the-shelf (COTS) precision navigation and landing system that facilitates all-weather landing operations. The flexible modular approach of the MMR allows configuration with one or more sensors, including VOR/ILS, Global Positioning Systems (GPS) and Microwave Landing Systems (MLS). The Global Navigation and Landing Unit (GNLU) family of Multi-Mode Receivers was developed by Rockwell Collins to support both commercial and military market requirements. The GNLU is available in two military configurations and supports analog and digital aircraft interfaces.

ADF
Rockwell Collins offers a wide range of Automatic Direction Finder (ADF) equipment, including the RSC-135G, SAR-136, MFD-134(V2), DF-430 and the ARN-149, satisfying a variety of operational needs. Rockwell Collins' ADFs offer mission flexibility, situational awareness, minimized risks and provide Search and Rescue (SAR) platforms with the most advanced stand-alone SAR V/UHF direction finders available. For example, the Rockwell Collins ARN-149 is the standard ADF in worldwide military use, providing a low-frequency, automatic direction finding function in a lightweight, easily installed system. The DF-430, a multi-mission direction finder covering the 30-410 MHZ band, is the newest generation of ADFs. Designed for mission success, the DF-430 is off-the-shelf equipment and a minimal risk solution. Rockwell Collins' Automatic Direction Finders are used by the U.S. Air Force and U.S. Army, as well as by many militaries around the world.
