Modular localization system for intelligent transport

Abstract

Positioning is a very important feature due to development of different Location Based Services (LBS). Ubiquitous positioning is the goal that is quite hard to achieve using one localization system. Global Navigation Satellite Systems (GNSS) are widely used in large number of applications. However, they are usable only if there is a line of sight to satellites. This paper deals with Modular Localization System that utilizes existing radio networks infrastructures together with GNSS. The modularity means use of multiple independent technologies that allow determining geographical position in different geographical environments. Modular Localization System which has been designed uses modules based on Global System for Mobile Communications (GSM), Global Positioning System (GPS) and IEEE 802.11b/g standard (Wi-Fi) to estimate the position of mobile device. Smartphones with the Android operating system were chosen as target devices which position will be estimated. © Springer International Publishing Switzerland 2014.
