UAV-based Localization Scheme for Battlefield Environments

Considering the emphasis on network-centric concepts of warfare in recent battlefield environments, the study of location information has become more important. This is because most military weapons use GNSSs (Global Navigation Satellite Systems) such as GPS and Galileo to track position information. Situations in which it is impossible to use these systems have been increased by many factors such as jamming attacks, reception failure, and politics. In this study, we propose a localization method that uses UAV (Unmanned Aerial Vehicle) and TDOA (Time Differential of Arrival) method to determine receiver position in situations in which using GNSS is locally impossible. We also consider the building of a slim-budget localization system independent of GNSS and how to operate it efficiently. The simulation results show that our scheme is applicable on battlefield, the feasibility is proved by the accuracy, the DOP (Dilution of Precise) and the coverage.
