Decrease in Accuracy of a Rotational SINS Caused by its Rotary Table's Errors

International Journal of Advanced Robotic Systems, 2014
We call a strapdown inertial navigation system (SINS) that uses the rotation auto-compensation technique (which is a common method to reduce the effect of the bias errors of inertial components) a ‘rotational SINS’. In a rotational SINS, the rotary table

Enhanced Strapdown Inertial Navigation System (SINS)/LiDAR Tightly Integrated Simultaneous Localization and Mapping (SLAM) for Urban Structural Feature Weaken Occasions in Vehicular Platform

Remote Sensing
LiDAR-based simultaneous localization and mapping (SLAM) offer robustness against illumination changes, but the inherent sparsity of LiDAR point clouds poses challenges for continuous tracking and navigation, especially in feature-deprived scenarios.

SmokeNav: Millimeter‐Wave‐Radar/Inertial Measurement Unit Integrated Positioning and Semantic Mapping in Visually Degraded Environments for First Responders

Advanced Intelligent Systems, Volume 6, Issue 12, December 2024.
In this work, SmokeNav, a system that fuses inertial sensor and millimeter‐wave radar for accurate user localization and metric map reconstruction in visually degraded environments, is presented. Using a foot‐mounted inertial sensor with human motion constraints, SmokeNav leverages inertial positioning to construct occupancy maps from radar data.

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

IET 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 ...
