Strapdown Attitude Computation: Functional Iterative Integration versus Taylor Series Expansion
Yuanxin Wu, Yury A. Litmanovich
This paper compares two basic approaches to solving ordinary differential equations, which form the basis for attitude computation in strapdown inertial navigation systems, namely,…
General Method for Prime-point Cyclic Convolution over the Real Field
Qi Cai, Tsung-Ching Lin, Yuanxin Wu +2
A general and fast method is conceived for computing the cyclic convolution of n points, where n is a prime number. This method fully exploits the internal structure of the cyclic…
iNavFIter: Next-Generation Inertial Navigation Computation Based on Functional Iteration
Yuanxin Wu
Inertial navigation computation is to acquire the attitude, velocity and position information of a moving body by integrating inertial measurements from gyroscopes and acceleromete…
On Inertial Navigation and Attitude Initialization in Polar Areas
Yuanxin Wu, Chao He, Gang Liu
Inertial navigation and attitude initialization in polar areas become a hot topic in recent years in the navigation community, as the widely-used navigation mechanization of the lo…
Attitude Reconstruction from Inertial Measurements: QuatFIter and Its Comparison with RodFIter
Yuanxin Wu, Gongmin Yan
RodFIter is a promising method of attitude reconstruction from inertial measurements based on the functional iterative integration of Rodrigues vector. The Rodrigues vector is used…
