Novel Calibration Algorithm for a Three-Axis Strapdown Magnetometer [PDF]
Sensors, 2014 A complete error calibration model with 12 independent parameters is established by analyzing the three-axis magnetometer error mechanism. The said model conforms to an ellipsoid restriction, the parameters of the ellipsoid equation are estimated, and the ellipsoid coefficient matrix is derived.

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.To address the limitations of existing wireless and inertial navigation systems, this paper proposes a high‐precision integrated positioning scheme based on particle filtering. The method introduces a high‐weight particle neighbourhood attraction mechanism to solve the common issue of particle degeneracy.

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.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 ...
