Abstract:	The Integrated Navigation Demonstrator is a demonstrator study of integrated navigation systems primarily for missile and UAV applications. Cost effective concepts for future integrated navigation systems based on low cost sensors and enhanced signal processing are studied. The navigation requirements for SAR applications are of special interest. The integrated navigation system is based on inertial navigation, supported by sensors like GPS, terrain referenced navigation, barometer and magnetometer. The terrain referenced navigation algorithm, TERNAV, uses both radar altimeter data and laser range finder data. A camera is also installed in the pod to collect data and evaluate algorithms for future integration of image based navigation. Terrain referenced navigation is demonstrated in real time both with laser and radar altimeters, using the Bayesian statistics based TERNAV algorithm. The video camera in the pod allows for passive height estimation and 3D-mapping. Preliminary image processing results show exciting possibilities for future integrations of camera based navigation algorithms as backup to GNSS.
