Delfin L-29

Since 1963, the Avionics Engineering Center (AEC) at Ohio University has been on the cutting edge of radionavigation system design, development, implementation and flight testing. In 2000, we augmented our fleet of propeller and turbo-prop aircraft with our first jet, an Aerovodochody L-29 Delfin jet from the Czech Republic.

One of the first research projects for the jet was GPS/INS integration testing. With its high altitude, high speed and high dynamic capability, the Delfin provides Ohio University the opportunity to test deeply coupled GPS/INS integrations under extreme flight conditions. For example, the aircraft can be made to execute roll maneuvers and the impact of the subsequent loss of GPS tracking (during inverted flight), and its impact on the integrated solution can be measured.
