Optimization and Commercialization of the Juvenile Eel/Lamprey Acoustic Transmitter and Micro-battery (Abstract)

Enhance studies to track in 3D and sub-meter accuracy the movements of sensitive species and early life stages of fish to advance understanding of migration timing and behaviors, habitat use, and survival rates, resulting in more informed management decisions regarding new and existing hydroelectric facilities and better designs of new hydropower systems that minimize or avoid environmental impacts.

Multiple Hypothesis Tracking for Opportunistic Transmitter Identification

The exploitation of radio frequency (RF) signals from Low Earth Orbit (LEO) communication satellites for the purposes of navigation is an active field of research. In this alternative navigation system, navigation observables are passively extracted from existing RF signals. Because these signals are not designed for navigation purposes and often have proprietary signal structures that are unknown to the receiver, they lack much of the information required for navigation systems or such information is unavailable to the receiver.
