Certifiable Alignment of GNSS and Local Frames via Lagrangian Duality

RA-L 2026

Estimating the absolute orientation of a local system relative to a global navigation satellite system (GNSS) reference often suffers from local minima and high dependency on satellite availability. Existing methods for this alignment task rely on abundant satellites unavailable in GNSS-degraded env

Roadside GNSS Aided Multi-Sensor Integrated System for Vehicle Positioning in Urban Areas

IROS 2025

Global navigation satellite system (GNSS) positioning can be significantly degraded due to multipath and non-line-of-sight (NLOS) signals in urban areas. Cellular vehicle-to-everything (C-V2X) technology provides new opportunities to enhance GNSS performance from a single intelligent vehicle by leve

Towards Robust GNSS Positioning and Real-time Kinematic Using Factor Graph Optimization

ICRA 2021poster

Global navigation satellite systems (GNSS) are one of the utterly popular sources for providing globally referenced positioning for autonomous systems. However, the performance of the GNSS positioning is significantly challenged in urban canyons, due to the signal reflection and blockage from buildi…

UrbanLoco: A Full Sensor Suite Dataset for Mapping and Localization in Urban Scenes

ICRA 2020poster

Mapping and localization is a critical module of autonomous driving, and significant achievements have been reached in this field. Beyond Global Navigation Satellite System (GNSS), research in point cloud registration, visual feature matching, and inertia navigation has greatly enhanced the accuracy…
