Journal ArticleDOI
Distributed Multi-Antenna Positioning for Automatic-Guided Vehicle.
TL;DR: A distributed multi-antenna positioning system is proposed, where multiple synchronous antennas are equipped on corners of an AGV to improve the availability and accuracy of positioning and an estimator based on the Levenberg–Marquardt algorithm is introduced to solve the nonlinear pseudo-range equations.
DissertationDOI
Evaluation of 2-dimensional ionosphere models for national and regional GPS networks in Canada
TL;DR: In this paper, a 2D spherical harmonic model and thin plate spline interpolation were proposed for real-time estimation of vertical delays at ionospheric grid points (IGPs).
Journal ArticleDOI
A Closed-Form Localization Method Utilizing Pseudorange Measurements From Two Nonsynchronized Positioning Systems
TL;DR: A new closed-form dual-system localization (CDL) approach that has low complexity and optimal localization accuracy, and does not require initialization and has lower computational complexity with comparable positioning accuracy is proposed.
Telematics Data in Motor Insurance: Creating Value by Understanding the Impact of Accidents on Vehicle Use
TL;DR: In this article, the authors present their own research on the Swiss National Science Foundation and express their gratitude to J. Margulici from the California Center of Innovative Transportation and Ikhlaq Sidhu from the Center for Entrepreneurship & Technology.
