Latest Patents

One of Qian Li's latest patents is the "Self-adaptive horizontal attitude measurement method based on motion state monitoring." This method utilizes a newly established state space model, where a horizontal attitude angle is treated as a state variable. It compensates for random constant zero offsets using an angular velocity increment and a specific force as measurement quantities. The method improves judgment conditions for a carrier's maneuvering state by integrating acceleration and angular velocity information from a micro electro mechanical system inertial measurement unit (MEMS-IMU). This innovation effectively reduces the influence of carrier maneuvering on horizontal attitude calculations, ensuring high measurement precision without external assistance.

Another significant patent is the "Strapdown inertial navigation heave measurement method using multiple low-pass filter units." This method involves collecting data from a gyroscope and an accelerometer to obtain attitude information. It establishes a relationship matrix between the body coordinate system and the geographic coordinate system, filtering low-frequency signals to achieve accurate velocity signals. The vertical acceleration is further processed to obtain precise heave displacement, showcasing Qian Li's expertise in navigation technologies.
