A Numerical-Integration Perspective on Gaussian Filters
TL;DR: A common base is provided for the first time to analyze and compare Gaussian filters with respect to accuracy, efficiency and stability factor and to help design more efficient filters by employing better numerical integration methods.
Journal ArticleDOI
Strapdown inertial navigation system algorithms based on dual quaternions
TL;DR: In this article, the design of INS algorithms based on dual quaternions is addressed, and a new numerical integration algorithm is structured to solve the three kinematic equations, utilizing the traditional two-speed approach originally developed in attitude integration.
Journal ArticleDOI
Velocity/Position Integration Formula Part I: Application to In-Flight Coarse Alignment
Yuanxin Wu,Xianfei Pan +1 more
TL;DR: An optimization-based coarse alignment approach that uses GPS position/velocity as input, founded on the newly-derived velocity/position integration formulae is proposed, and can serve as a nice coarse in-flight alignment without any prior attitude information for the subsequent fine Kalman alignment.
Journal ArticleDOI
Optimization-based alignment for inertial navigation systems: Theory and algorithm
TL;DR: It is shown that the INS attitude alignment can be equivalently transformed into a “continuous” attitude determination problem using infinite vector observations.
Journal ArticleDOI
Improved multi-position calibration for inertial measurement units
TL;DR: In this paper, an improved multi-position calibration approach is proposed based on the fact that the norm of the measured outputs of the accelerometer and gyroscope cluster are equal to the magnitudes of specific force and rotational velocity inputs, respectively.
