Overview of Current Indoor Positioning Systems

Combination of Indoor and Outdoor Positioning

Indoor and outdoor environments create contradictory conditions for positioning and guidance of machines. While indoor environments are limited in size to rooms and buildings, outdoor positioning capabilities require regional or even global coverage. Secondly, the difficulty of receipting satellite signals indoors has triggered development of high sensitive and AGNSS receivers – with many issue...

Overview of RFID-Based Indoor Positioning Technology

Radio frequency identification (RFID) technology was originally invented for military uses. From 1980s, commercial RFID products started to be available and they were mainly applied in areas of supply chains, transport, manufacturing, personnel access, animal tagging, toll collection etc. Nowadays, RFID has been recognised as an emerging technology for ubiquitous positioning (UP), especially in...

Advances in Media Technology Mobile Interaction and Mobile Services

With the rapid development of communication and information technology, our demand of wireless localization is increasing day by day. This paper gives an overview of the existing wireless indoor positioning techniques. Several typical indoor positioning systems and the techniques they have used are described and analyzed. The possible trend of positioning system research are presented.

Indoor and Outdoor Cooperative Real-time Positioning System

This paper proposes a cooperative real-time positioning system to solve both indoor and outdoor location tracking problem for disaster aid, we conduct a detailed overview of pre-existing indoor positioning systems, give architecture of cooperative positioning system, and introduce the least square method to improve accuracy of time difference of arrival (TDOA) positioning algorithm. Meanwhile, ...
