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.…
A Case Study Analysis for Designing a Lunar Navigation Satellite System with Time-Transfer from Earth-GPS
Sriramya Bhamidipati, Tara Mina, Grace Gao
Recently, there has been a growing interest in the use of a SmallSat platform for the future Lunar Navigation Satellite System (LNSS) to allow for cost-effectiveness and rapid depl…
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…
