Description: Global navigation satellite systems have been revolutionising surveying, geodesy, navigation and other position/location sensitive disciplines. However, there are two intrinsic shortcomings in such satellite-based positioning systems: signal attenuation and dependence on the geometric distribution of the satellites. Consequently, the system performance can decrease significantly under some harsh observing conditions. To tackle this problem, some new concepts of positioning with the use of pseudo-satellites have been developed and tested. Pseudo-satellites, also called pseudolites, are ground-based transmitters that can be easily installed wherever they are needed. They therefore offer great flexibility in positioning and navigation applications. Although some initial experimental results are encouraging, there are still some challenging issues that need to be addressed. This paper reviews the historical pseudolite hardware developments and recent progress in pseudolite-based positioning, and discusses the current technical issues. Platform: |

Description: The field of radionavigation signals and systems has seen significant growth in recent years. Satellite systems are very efficient, but owing to their limited exposure and/or availability in some environments, they do not cover the whole spectrum of applications. Thus, many other positioning techniques are being developed.
Now, Global Positioning presents an overview of the strengths and weaknesses of various systems with a specific emphasis on those that are satellite-based. Beginning with a description of the evolution of positioning systems, the book provides detailed coverage of the three main Global Navigation Satellite System (GNSS) constellations, discusses how to cope with indoor positioning, defines development activities and commercial positioning, and proposes a vision for the future of the field.

Description: In recent years, stepping with the popularization of smart phone and the
development of mobile communication infrastructure, the conditions for ubiquitous
computing society become more and more complete. In the vision of ubiquitous
computing society, LBS (Location Based Service) that provides an added value to an
unprecedented user experience has been paid a great deal of attention by mobile
operators all over the world. As the core technology for LBS, various positioning
systems have been studied extensively. For the outdoor environment GPS is mature
and common. However, the performance of GPS in indoor environment is bad.
Moreover, currently there is no technique whose accuracy and cost are appropriate for
deployment in huge areas. -In recent years, stepping with the popularization of smart phone and the

Description: 室内定位技术综述，很全。涵盖了摄像机/红外/超声/UWB等等技术的对比，给出了每种技术的定位精度和范围，非常具有参考价值。-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 positioning has become excellent, but
many mass market applications require seamless positioning capabilities in all environments.
Therefore indoor positioning 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. We are still far away from
achieving cheap provision of global indoor positioning with an accuracy of 1 meter. Current
systems require dedicated local infrastructure and customized mobile units. As a result, the
requirements for every application must be analyzed separately to provide an indiv Platform: |
