Set-Valued Shadow Matching Using Zonotopes for 3-D Map-Aided GNSS Localization

Sriramya Bhamidipati, Shreyas Kousik, Grace Gao

Unlike many urban localization methods that return point-valued estimates, a set-valued representation enables robustness by ensuring that a continuum of possible positions obeys s…

Mosaic Zonotope Shadow Matching for Risk-Aware Autonomous Localization in Harsh Urban Environments

Daniel Neamati, Sriramya Bhamidipati, Grace Gao

Risk-aware urban localization with the Global Navigation Satellite System (GNSS) remains an unsolved problem with frequent misdetection of the user's street or side of the street.…

Robust GPS-Vision Localization via Integrity-Driven Landmark Attention

Sriramya Bhamidipati, Grace Xingxin Gao

For robust GPS-vision navigation in urban areas, we propose an Integrity-driven Landmark Attention (ILA) technique via stochastic reachability. Inspired by cognitive attention in h…

GPS Spoofing Mitigation and Timing Risk Analysis in Networked PMUs via Stochastic Reachability

Sriramya Bhamidipati, Grace Xingxin Gao

To address PMU vulnerability against spoofing, we propose a set-valued state estimation technique known as Stochastic Reachability-based Distributed Kalman Filter (SR-DKF) that com…

SLAM-based Integrity Monitoring Using GPS and Fish-eye Camera

Sriramya Bhamidipati, Grace Xingxin Gao

Urban navigation using GPS and fish-eye camera suffers from multipath effects in GPS measurements and data association errors in pixel intensities across image frames. We propose a…
