An attitude calculation algorithm based on WNN-EKF
In the strapdown inertial navigation system, the attitude information is obtained through an inertial measurement unit (IMU) device, which mainly includes a triaxial gyroscope, a triaxial accelerometer and a triaxial magnetometer.

The existing vehicle dynamics model (VDM)‐based navigation rely on high‐order VDMs to serve as a virtual Doppler velocity log, causing complexity of identification algorithm as well as imperfect identification performance. To solve this problem, this paper proposes a reduced‐order VDM structure and its parameter setting method to minimise navigation ...

Effect of Strapdown Integration Order and Sampling Rate on IMU-Based Attitude Estimation Accuracy
This paper deals with the strapdown integration of attitude estimation Kalman filter (KF) based on inertial measurement unit (IMU) signals. In many low-cost wearable IMU applications, a first-order is selected for strapdown integration, which may degrade

A Student's T Distribution‐Based Filter Design for SINS/GNSS With Heavy‐Tailed Noise
To reduce the affection of outliers caused by heavy‐tailed noise, the noise model is constructed by the Student's T distribution rather than the Gaussian distribution, and the related probability density functions (PDF) are adaptively modelled as student's T PDFs with different DoF parameters.
