Code Optimization for Strapdown Inertial Navigation System Algorithm [PDF]

open access: yes, 2018
Inertial navigation systems are in common use for decades due to its advantages. Since INS outputs are usually used for inputs in different control algorithms (depending on applications), INS will induce certain errors and limitations. This chapter deals

An Autonomous Vehicle Navigation System Based on Inertial and Visual Sensors

open access: yesSensors, 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 Tightly Coupled Fusion Positioning Method Based on Particle Filtering With Effective Particle Neighbourhood Attraction Optimisation

open access: yesIET 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.

A Novel Reduced‐Order Underwater Vehicle Dynamics Model for VDM‐Based Navigation: Structure and Parameter Setting

open access: yesIET 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 ...

Research on the automotive sensor–aided low-cost inertial navigation system for land vehicles

open access: yesAdvances 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.
