Partially Supervised Reinforcement Learning for GPS-Denied Navigation
… work, we propose a learning framework for aerial navigation in the presence of changing dynamics and limited positional information. Specifically, we consider a drone navigation task where a drone at one time has access to GPS location information, which it has now lost and needs to navigate in …

Multiple hypothesis positioning algorithm for robust GPS-denied navigation
In the past few decades, GPS has become the dominant source of precision navigation and is often required for many modern systems to operate. However, recent exposure of GPS vulnerabilities have called into question its overall resiliency and shown necessity for robust alternatives. Precision …

Design, Development and Implementation of Intelligent Algorithms to Increase Autonomy of Quadrotor Unmanned Missions
… through flight testing. A vision-based navigation scheme is developed to enhance the quadrotor autonomy under GPS denied environments. An optical flow sensor and a laser range finder are used within an Extended Kalman Filter for position estimation and its estimation performance is …

Significance of omnidirectional fisheye cameras for feature-based visual SLAM
Robust GPS-denied navigation of mobile robots is becoming increasingly important as robots become more ubiquitous. Cameras are powerful sensors for this application due to their low cost and high information density. The task of using camera-based computer vision techniques for navigation is …

Beyond LiDAR for Unmanned Aerial Event-Based Localization in GPS Denied Environments
… an Unmanned Aerial Vehicle (UAV) especially when GPS is unreliable due to coverage blackouts and/or GPS degradation [10]. Furthermore, if it is possible to deploy multiple in-situ static intelligent acoustic autonomous sensors that can identify anomalous sounds given context, then the sensors can …
