Android positioning: from stand-alone to cooperative approaches

Stand-Alone Satellite-Based Global Positioning

Stand-Alone and Hybrid Positioning Using Asynchronous Pseudolites

global navigation satellite system (GNSS) receivers are usually unable to achieve satisfactory performance in difficult environments, such as open-pit mines, urban canyons and indoors. Pseudolites have the potential to extend GNSS usage and significantly improve receiver performance in such environments by providing additional navigation signals. This also applies to asynchronous pseudolite sys...

LocataNet: Intelligent time-synchronised pseudolite transceivers for cm-level stand-alone positioning

The use of GPS for indoor positioning poses difficult challenges due to very weak signal levels, and accuracies are typically of the order of tens to hundreds of metres at best. To overcome this severe limitation, Locata Corporation has invented a new positioning technology called Locata, for precision positioning both indoors and outside. Part of the “Locata technology” consists of a time-sync...

Why science cannot stand alone.

In an era in which certain arenas of scientific research have become increasingly controversial, this article critically evaluates what it means to "believe in science." Many scientists today seem to claim a sovereign right to no political interference under the rubric of freedom. This article questions such a notion, and explores the dominance of science and the silencing of moral voices by un...

Confidence Stand-alone Sw Systems

CONFIDENCE Ubiquitous Care System to Support Independent Living is one of the most interesting FP7 projects for The department of intelligent systems at JSI. In this paper we present WP3, the major SW component of the system that is also implemented as two stand-alone versions of the system. In this paper, the two systems are presented from the user viewpoint based on five manuals.
