Inertial-based Navigation by Polynomial Optimization: Inertial-Magnetic Attitude Estimation
Maoran Zhu, Yuanxin Wu
Inertial-based navigation refers to the navigation methods or systems that have inertial information or sensors as the core part and integrate a spectrum of other kinds of sensors…
Investigation of Enhanced Inertial Navigation Algorithms by Functional Iteration
Hongyan Jiang, Maoran Zhu, Yuanxin Wu
The defects of the traditional strapdown inertial navigation algorithms become well acknowledged and the corresponding enhanced algorithms have been quite recently proposed trying…
ChevOpt: Continuous-time State Estimation by Chebyshev Polynomial Optimization
Maoran Zhu, Yuanxin Wu
In this paper, a new framework for continuous-time maximum a posteriori estimation based on the Chebyshev polynomial optimization (ChevOpt) is proposed, which transforms the nonlin…
Attitude Reconstruction from Inertial Measurement: Mitigating Runge Effect for Dynamic Applications
Yuanxin Wu, Maoran Zhu
Time-equispaced inertial measurements are practically used as inputs for motion determination. Polynomial interpolation is a common technique of recovering the gyroscope signal but…
A Trident Quaternion Framework for Inertial-based Navigation Part I: Rigid Motion Representation and Computation
Wei Ouyang, Yuanxin Wu
Strapdown inertial navigation research involves the parameterization and computation of the attitude, velocity and position of a rigid body in a chosen reference frame. The communi…
A Trident Quaternion Framework for Inertial-based Navigation Part II: Error Models and Application to Initial Alignment
Wei Ouyang, Yuanxin Wu
This work deals with error models for trident quaternion framework proposed in the companion paper (Part I) and further uses them to investigate the odometer-aided static/in-motion…
