A New Array Pseudolites Technology for High Precision Indoor Positioning

Locata: A New Positioning Technology for High Precision Indoor and Outdoor 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-synch...

A New Pseudolite-Based Positioning Technology For High Precision Indoor and Outdoor Positioning

A real-time positioning technology that can operate indoors and outside anywhere in the world, with sub-cm accuracy, and at low cost, is the ultimate goal for many researchers. GPS can achieve cmlevel kinematic positioning accuracy, but with some major constraints. First and foremost the use of GPS signals for indoor positioning poses very difficult challenges, due to the very weak signal level...

High-Precision Ad-Hoc Indoor Positioning in Challenging Industrial Environments

This paper addresses the problem of providing high-precision positioning in industrial environments. Such environments are extremely challenging due to the adverse effects of multipath fading caused by the abundance of metallic objects, the physical layout of the environment which is often complex, and the lack of fixed positioning system infrastructure. Several technologies are assessed with r...

High Precision Indoor and Outdoor Positioning using LocataNet

Today, GPS is the most popular and widely used threedimensional positioning technology in the world. However, in many everyday environments such as indoors or in urban areas, GPS signals are not available for positioning (due to the very weak signals). Even with high sensitivity GPS receivers, positioning for urban and indoor environments cannot be guaranteed in all situations, and accuracies a...
