Tactical Field Localization without GNSS

Global Navigation Satellite Systems (GNSS) is widely used for timing and localization in many critical industrial and military applications. However, it is not a nationalized technology and also suffers from jamming and spoofing attacks which makes it unreliable for standalone use in military systems. In this study, an alternative localization solution based on radio communication is developed without GNSS. This solution utilizes the time synchronization algorithm which is needed for preserving the network functionality. Several localization algorithms based on propogation delay measurements, which are mutually shared by the time synchronization algorithm, are studied. Better performing algorithms are integrated into the embedded software while employing the underlying waveform capabilities as much as possible. Therefore, a solution with advanced protection against electronic warfare is developed which requires no additional hardware. Studied localization methods are extensively investigated for various system parameters along with their resulting localization performance.
