Aerial Localization and Navigation for Surveillance of Large, Featureless, GNSS‐Denied Maritime Environments

Journal of Field Robotics, Volume 42, Issue 8, Page 4215-4235, December 2025.
ABSTRACT In this study, we tackle the problem of surveilling a large area over the sea without access to the global navigation satellite system (GNSS) while searching for the known target vessel. The system utilizes an unmanned aerial vehicle (UAV) equipped with long‐range radio frequency (LoRa) localization and an RGB camera to detect the target ...

Risk‐aware autonomous search and rescue with multiagent reinforcement learning

Risk Analysis, Volume 45, Issue 12, Page 4490-4504, December 2025.
Abstract Autonomous navigation in dynamic high‐consequence environments, such as search and rescue (SAR) missions, often relies on multiagent robotic systems that need to learn and adapt to changing conditions. Adversarial risks can introduce further challenges in such a setting where an autonomous agent may exhibit deviations in their learned actions ...
