IET Communications, Volume 17, Issue 17, Page 1962-1973, October 2023., 2023 This paper proposes the adaptive weighted federated Kalman filtering based on Mahalanobis distance (MD‐AWFKF). Firstly, by calculating the Mahalanobis distance between the predicted value and the measured value of the system state, the random fluctuation of the measured value is detected.

Integrated Navigation Method of Aerospace Vehicle Based on Rank Statistics
International Journal of Aerospace Engineering, Volume 2023, Issue 1, 2023., 2023 The large dynamic and high‐speed flight of aerospace vehicle will bring unpredictable conditions to its navigation system, resulting in that its system random noise probability distribution will no longer meet the preconditions of Gaussian distribution preset by the existing filter algorithm, thus reducing the accuracy of the navigation system.

Swimming Attitude for Tracking Error Correction Based on Mahony Algorithm
Mobile Information Systems, Volume 2022, Issue 1, 2022., 2022 Swimming is predominantly a long‐distance endurance sport. In this sport, like in many others, monitoring and tracking swimming attitude error correction and how it changes over time is critical. Besides, in swimming posture measurement, due to the absorption and refraction of various signals of water, sensors relying on external information cannot ...
