MUMBAI, India, March 13 -- Intellectual Property India has published a patent application (202621012576 A) filed by Prof. Aasha Kantekar; and Dr. Venkat P. Patil, Maharashtra, on Feb. 5, for 'system and method for offline indoor navigation in complex railway station environments using graph-based geospatial modelling and on-device pathfinding.'
Inventor(s) include Prof. Aasha Kantekar; Dr. Venkat P. Patil; Dr. Sunil S. Chavan; Dr. Umakant B. Gohatre; Prof. Smita Y. Wadekar; Mr. Anuyash Koli; Mr. Pravin Hivare; Mr. Om Kambli; and Mr. Mohammed Shaikh.
The application for the patent was published on March 13, under issue no. 11/2026.
According to the abstract released by the Intellectual Property India: "Navigating large, multi-level transit hubs for any Typical Railway Station poses challenges for commuters due to complex layouts, multiple platforms, foot over-bridges, and dispersed access points. General-purpose navigation tools lack the detailed indoor data required to support seamless movement across these interconnected spaces. This research work presents RailNav, an offline-first mobile navigation system purpose-built for the Railway station complex. The solution is grounded in a high-precision digital twin created in QGIS, where walkable paths and key facilities are modelled as a geospatial graph. The Android application which can be developed using the MVVM architecture, integrates an on-device A* algorithm with a Haversine heuristic to compute optimal pedestrian routes without internet connectivity. A user-friendly interface built with Jetpack Compose and OSMDroid ensures interactive, context-rich visualization. By combining accurate spatial data with efficient pathfinding, RailNav enhances indoor wayfinding, improves accessibility, and contributes to smarter public transportation infrastructure."
