Our dynamics framework characterized performance of competing geolocation algorithm implementations, including Time Difference of Arrival (TDOA), Frequency Difference of Arrival (FDOA), and other techniques to evaluate beacon geolocation performance in a variety of environments and space geometries. Algorithms are further tested with hardware-in-the-loop (HIL) using our wideband real-time signal processing capabilities.
By processing data from NASA’s exercise-based database, our solution showed potential for real-time beacon geolocation when fully integrated with a base station. We refined our geolocation algorithms to achieve an accuracy within 3-5 km for 95% Circular Error Probable (CEP), surpassing the SARSAT system requirements of 7 km for 95% CEP. This innovation enhances search and rescue mission effectiveness, ultimately helping to save lives.
