Indoor positioning and navigation, part III: navigation systems

Abstract

In the age of automation the ability to navigate persons and devices in indoor environments has become increasingly important for a rising number of applications. With the emergence of global satellite positioning systems, the performance of outdoor navigation has become excellent, but many mass market applications require seamless navigation capabilities in all environments. Therefore indoor navigation has become a focus of research and development during the past decade. It has by now become apparent that there is no overall solution based on a single technology, such as that provided outdoors by satellite-based navigation.
