Robust adaptive non‐linear alignment algorithm for SINS/DVL integrated navigation system based on variational Bayesian

open access: yesIET Science, Measurement &Technology, Volume 18, Issue 9, Page 524-539, November 2024.
The proposed algorithm VBRAUKF is useful for dynamic alignment of SINS/DVL. According to the inaccurate modelling of the observation model, an adaptive estimation strategy for the measurement noise covariance is designed by Variational Bayesian algorithm based on unscented Kalman filter algorithm to solve dynamic attitude alignment for SINS/DVL ...

Data‐driven observability analysis and enhancement for radome slope estimation with constraints on impact angle and terminal acceleration

open access: yesIET Radar, Sonar &Navigation, Volume 18, Issue 10, Page 1887-1907, October 2024.
The authors propose a data‐driven observability analysis method for radome aberration estimation systems with LOS‐angle‐only measurements, and an observability‐enhanced guidance law that considers both impact angle and terminal acceleration constraints.

SHAKF‐PU: Sage–Husa Adaptive Kalman Filtering‐Based Pedestrian Characteristic Parameter Update Mechanism for Enhancing Step Length Estimation in Pedestrian Dead Reckoning

open access: yesApplied Bionics and Biomechanics, Volume 2024, Issue 1, 2024.
Step length estimation (SLE) is the core process for pedestrian dead reckoning (PDR) for indoor positioning. Original SLE requires accurate estimations of pedestrian characteristic parameter (PCP) by the linear update, which may cause large distance errors.

Improved Pedestrian Location Method for the Indoor Environment Based on MIMU and sEMG Sensors

open access: yesJournal of Sensors, Volume 2024, Issue 1, 2024.
In order to guarantee the pedestrian location accuracy for the indoor environment, an improved pedestrian location method based on the improved Mahony complementary filter algorithm is proposed by the data fusion of microinertial measurement unit (MIMU) and sEMG sensors, which are installed on the lower limbs.

A Robust Self-Alignment Method for Ship’s Strapdown INS Under Mooring Conditions

open access: yesSensors, 2013
Strapdown inertial navigation systems (INS) need an alignment process to determine the initial attitude matrix between the body frame and the navigation frame. The conventional alignment process is to compute the initial attitude matrix using the gravity
