Bridging the Gaps: High-Integrity GNSS RTK for Urban Robotics - Challenges and Potential Solutions

Urban environments present significant challenges for GNSS RTK due to signal obstructions, multipath effects, and dynamic interference, limiting its reliability for robotics applications. High-integrity GNSS RTK is essential to bridge these gaps and enable precise and robust localization for autonomous systems operating in dense cityscapes. This talk explores the key challenges in urban GNSS RTK, focusing on sensor fusion algorithms that integrate GNSS with inertial sensors, LiDAR, and vision-based localization. We will discuss innovative solutions, including advanced filtering techniques, fault detection mechanisms, and learning-based approaches to enhance positioning accuracy and integrity. By addressing these challenges, we can unlock new possibilities for autonomous vehicles, delivery drones, and smart city robotics. The talk will provide insights into the latest research developments and practical considerations for deploying high-integrity GNSS RTK solutions in urban environments, paving the way for a future where robotics can navigate cities with precision and reliability.
