This invention relates to the field of environmental perception and dynamic state estimation technology in high-altitude wind power generation systems, specifically to a method and system for real-time estimation of high-altitude wind field state based on multi-sensor fusion. It simultaneously acquires data from an inertial measurement unit (IMU), a GNSS receiver, and a three-dimensional anemometer. Using the IMU reference point as a benchmark, it employs error-state Kalman filtering for aircraft state estimation and incorporates a long short-term memory (LSTM) network for adaptive adjustment of process noise. Lever arm compensation is achieved through a pre-calibrated installation position vector obtained from offline geometric calibration, eliminating the velocity component induced by aircraft rotation and improving the accuracy of airflow observation.
