Abstract	Athena Technologies has achieved several new milestones in the half a year since Spring 2006 SAE committee meeting. Shadow 200 Tactical UAV by AAI Corp., flown with Athena’s Guidestar GS211e integrated flight control, navigation, and vehicle management system, achieved 100,000 operational flight hours in Iraq. Lockheed Martin SkunkWorks awarded Athena a contract to provide an entire flight control system for its morphing aircraft (based on an off-the-shelf Guidestar GS111m). General Atomics awarded Athena a contract for equipping its fleet of US Army Warrior Extended Range/Multiple Payload (ERMP) with dual backup INS/GPS integrated navigation systems (our new tactical grade Guidestar GS511). MicroGuidestar - a four ounce flight control system with a complete sensor suite - was added to Athena’s Guidestar product family. Under DARPA’s Damage Tolerance program, Athena is preparing a flight demonstration of automatic landing after sustaining simulated battle damage. This capability is enabled by Athena’s adaptive control algorithms. Full nonlinear simulations show that, for example, after a significant damage to wing trailing edge, including loss of an aileron, the test bed aircraft (turbojet powered F-18 model) can not adequately perform a last-minute decrabbing maneuver in a strong cross-wind due to excessive coupling between sideslip and bank response. It has been shown in simulation that Athena’s adaptive control algorithms recover the original performance by suppressing cross-axis response.
