An Autonomous Vehicle Navigation System Based on Inertial and Visual Sensors
Sensors, 2018 The strapdown inertial navigation system (SINS) is widely used in autonomous vehicles. However, the random drift error of gyroscope leads to serious accumulated navigation errors during long continuous operation of SINS alone.

A Student's T Distribution‐Based Filter Design for SINS/GNSS With Heavy‐Tailed Noise
IET Electric Power Applications, Volume 19, Issue 1, January/December 2025.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.

Research on the automotive sensor–aided low-cost inertial navigation system for land vehicles
Advances in Mechanical Engineering, 2019 When a low-cost micro-electro-mechanical system inertial measurement unit is used for a vehicle navigation system, errors will quickly accumulate because of the large micro-electro-mechanical system sensor measurement noise.

IET Radar, Sonar &Navigation, Volume 19, Issue 1, January/December 2025.This work explores underwater TMA by incorporating time delay and Doppler frequency measurements along with angle data, eliminating the need for own‐ship manoeuvre and improving estimation accuracy in presence of non‐Gaussian sensor noise. Furthermore, since the own‐ship's position is inherently uncertain due to navigation errors, this work addresses ...

Multiframe Target Localization With Strapdown Seeker Based on Self‐Adaptive L‐SHADE
International Journal of Aerospace Engineering, Volume 2025, Issue 1, 2025.Strapdown seekers are increasingly used in the terminal guidance for the advantages of small size and low cost. However, due to the coupling of the seeker with the missile and its limited field of view, there is a risk of losing the target. This paper proposes a multiframe fusion target localization method for missiles with strapdown seekers, which can
