Pseudolites as UAV Navigation Support

The augmentations of the Global Navigation Satellite Systems (GNSS) are widely used. Pseudolites make it possible for users to augment navigation systems considering specific local needs of users. Urban canyons, rough terrain, radio signal disturbances are only some of the problems that can make GNSS satellite signal unavailable or disturbed. The navigation of Unmanned Aerial Vehicles (UAV) has specific requirements on GNSS navigation that can be solved by a network of pseudolites. Pseudolites augmentations were analyzed in the UAV test flight area. Dilutions of Precision (GDOP, PDOP, HDOP, VDOP and TDOP) were used to analyze the quality of pseudolites and GNSS radio-navigation network geometry. The scenarios considering the UAV navigation using ground-based pseudolites and satellite based GPS, GLONASS and Galileo are analyzed.
