Optimization-based alignment for strapdown inertial navigation system: comparison and extension [PDF]
In this paper, the optimization-based alignment (OBA) methods are investigated with main focus on the vector observations construction procedures for the strapdown inertial navigation system (SINS). The contributions of this study are twofold. First the OBA method is extended to be able to estimate the gyroscopes biases coupled with the attitude based ...

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

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 ...

A Student's T Distribution‐Based Filter Design for SINS/GNSS With Heavy‐Tailed Noise
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.
