AN/ARA-63 Open Architecture Landing Systems Prototype Project

Project Number:



Sierra Nevada Corporation

Award Amount:



The AN/ARA-63D Tactical Instrument Landing System (TILS) is an all-weather aircraft approach guidance system consisting of ground and airborne equipment. This equipment receives coded microwave transmissions from the ground or carrier-based azimuth and elevation transmitters and decodes these signals for display on a cross-pointer indicator in the aircraft cockpit. The purpose of this project is to develop a TILS with the same form, fit, and function as the current AN/ARA-63D design to address the obsolescence issues with the current system.
