Autonomous Aerial Refueling Demonstration (AARD) Program
In 2006 SNC developed and demonstrated the first ever autonomous in-flight refueling engagement compatible with existing probe-and-drogue systems. With some modification, the technology should also be compatible with other refueling methods such as boom refueling systems. The demonstration system employed a combination of high-accuracy and high-integrity Relative Navigation GPS, Inertial Navigation System (INS) and high resolution optical tracking.
SNC developed the AAR system under a DARPA contract and worked closely with DARPA and NASA to develop a safe and effective flight test demonstration. For precision guidance, the AARD system uses a SNC developed blended relative GPS/INS solution and an optical tracker subsystem. The GPS/INS solution provides the primary guidance during approach and departure to the drogue, as well as provides the station keeping function during the minutes-long tanking operation. The optical tracker is used close in to mate the probe and drogue.
Dubbed "a significant milestone" by DARPA and "unbelievably stable and smooth" by the NASA test pilot, the successful autonomous plugs were the culmination of a 15- month DARPA-funded technology demonstration program. SNC developed the AARD navigation, guidance and control hardware and software for both the F/A-18 and the Omega Air 707 tanker and integrated an optical tracker solution to ensure a precise and safe probe and drogue engagement.
