Latest Patents

One of his latest patents is a navigation and positioning system for underwater gliders. This system incorporates a micro-electro-mechanical system inertial measurement unit, a global positioning system receiving module, a triaxial magnetometer, a Doppler velocimeter, and an integrated navigation hardware processing system. The system is designed to stop the underwater glider in real time if a navigation and positioning error becomes too large, switching from the underwater working state to an up floating error correction state. When the velocity and location errors of the GPS/INS integrated navigation system fall below specified thresholds, the glider resumes its underwater operations. An H∞ Kalman filter algorithm based on an adaptive multiple fading factor is established to ensure the robustness and adaptability of the navigation and positioning system.

Another notable patent is a dual-filter-based transfer alignment method under dynamic deformation. This method addresses the challenges posed by dynamic deformation angles that can reduce the accuracy of transfer alignment. The transfer alignment filter is divided into two parts: the first part estimates the bending deformation angle and the coupling angle using an attitude matching method, while the second part estimates a dynamic lever arm through a 'speed plus angular speed' matching method.
