MUMBAI, India, Jan. 23 -- Intellectual Property India has published a patent application (202641001689 A) filed by Muralee Krishnan C R, Cherukara, Kerala, on Jan. 7, for 'system and method for 3d navigation in gnss-denied environments using a hierarchical visually-coupled pseudolite array and neural-network based sensor fusion.'
Inventor(s) include Muralee Krishnan C R.
The application for the patent was published on Jan. 23, under issue no. 04/2026.
According to the abstract released by the Intellectual Property India: "The invention discloses a system for 3D navigation in GNSS-denied environments (e.g., underwater) using a deployable hierarchical array. A Master Node stays in a known location, while Reference Nodes descend into the denied zone, maintaining rigid geometry via optical locking (Fig. 1). The system further implements a "Neural Mesh" technique (Fig. 2), where a cluster of ships and anchors act as cooperative sensing layers. These layers relay acoustic data to a shore-based Tower, which utilizes a hybrid neural analysis and weighted average algorithm to compute the precise coordinates of targets (e.g., submarines) by dynamically weighting signals based on quality, without requiring onboard computation at the target."
