The UAV-RT system is developed by the Dynamic and Active Systems Lab under a National Science Foundation grant (Award 1556417). Using background knowledge from biologist and engineers, the team seeks to improve the efficiency of VHF tag localization by integrating a software defined radio (SDR) onto a unmanned aerial vehicle (UAV). While current tracking methods are time consuming and require the combination of experienced trackers and manned flights, our system uses custom signal processing algorithms and autonomous flight to provide tag localization estimates.  The resulting system is documented and distributed for open source use and field adoption. This project is headed by Michael Shafer, PhD, and a team at Northern Arizona University.
