MUMBAI, India, July 24 -- Intellectual Property India has published a patent application (202611055874 A) filed by Sooryauday Aerial Vehicles Pvt. Ltd. on May 01, 2026, for Inertial Navigation Accuracy Improvement System For An Unmanned Aerial Vehicle And Method Thereof.
Inventors include Kapil Dev; and Dr. Uday Narang.
The application for the patent was published on July 17, 2026, under issue no. 29/2026.
Abstract: An inertial navigation accuracy improvement system for an unmanned aerial vehicle and method thereof, comprises a hydrogen based propulsion unit 201 to provide electrical propulsion power for extended duration flight, an inertial navigation unit 102 to estimate position, velocity, and altitude during flight, a drift estimation module 202 to determine one or more of inertial drift growth, sensor bias accumulation, covariance expansion, and navigation uncertainty, an energy margin estimation module 203 to estimate temporal energy margin based on remaining hydrogen fuel, projected endurance, mission power demand, and predicted energy required for mission completion, a control unit to initiate a drift correction window during mission execution, a flight command module 204 to command reduced dynamic flight mode during the drift correction window, and a mission resumption module to return the UAV 101 from the reduced dynamic flight mode to a nominal mission flight mode after completion of the drift correction window.
