A low cost 3D-display and navigation system is described which presents guidance information in a 3-dimensional format to the pilot. For achieving the low cost goal, Commercial-off-the-Shelf components are used. The visual information provided by the 3D-display includes a presentation of the future flight path and other guidance elements as well as an image of the outside world. For generating the displayed information, a PC will be used. An appropriate computer software is available to generate the displayed information in real-time with an adequately high update rate. Precision navigation data which is required for accurately adjusting the displayed guidance information are provided by an integrated low cost navigation system. This navigation system consists of a differential global positioning system and an inertial measurement unit. Data from the navigation system is fed into an onboard-computer, using terrain elevation and feature analysis data to generate a synthetic image of the outside world. The system is intended to contribute to the safety of General Aviation aircraft, providing an affordable guidance and navigation aid for this type of aircraft. The low cost 3D display and navigation system will be installed in a two-seat Grob 109B aircraft which is operated by the Institute of Flight Mechanics and Flight Control of the Technische Universitchen as a research vehicle.
