ILoA: Indoor Localization Using Augmented Vector of Geomagnetic Field

open access: yesIEEE Access, 2020
In this article, we propose a new geomagnetic localization scheme, named ILoA, to address error accumulation and global localization. Global localization is a fundamental problem that determines the initial pose under global uncertainty.
