Dr. Hsu named in Stanford Top 2% Most-Cited Scientists

Dr. Li-Ta Hsu has been included in the Stanford University/Elsevier ranking of the top 2% most-cited scientists worldwide, maintaining this recognition for five consecutive years from 2021 to 2025. The Stanford/Elsevier list, compiled by Professor John Ioannidis and his team at Stanford University, uses Scopus citation data to identify approximately 200,000 scientists across all disciplines who rank in the top 2% by citation impact. The database provides standardized metrics including total citations, h-index, and a composite citation indicator, offering a transparent and data-driven measure of scholarly influence.

Dr. Hsu’s sustained presence on this list reflects the broad impact of his research in GNSS positioning, 3D mapping-aided navigation, multi-sensor fusion, and integrity monitoring for urban environments. His work on robust positioning techniques for dense urban canyons, where satellite signals are frequently obstructed or reflected by buildings, has attracted significant attention from the navigation and intelligent transportation communities. Publications on topics such as NLOS detection and mitigation, factor graph optimization for GNSS/INS integration, and open-source datasets for benchmarking urban navigation have contributed to his citation record.

Being named among the top 2% most-cited scientists for five consecutive years is a notable milestone that underscores the continued relevance and influence of the research conducted at the Intelligent Positioning and Navigation Laboratory (IPNL) at The Hong Kong Polytechnic University. It also highlights the growing importance of reliable positioning technology as autonomous driving, urban air mobility, and location-based services place increasing demands on navigation accuracy and integrity in challenging environments.
