On the GDOP and Accuracy for Indoor Positioning
IEEE Transactions on Aerospace and Electronic Systems, 2012Position accuracy and geometric dilution of precision (GDOP) analysis are presented for indoor mesh positioning systems in multipath and non-line-of-sight (NLOS) propagation environments. Concise analytical formulas are derived for the position error statistics in the presence of biased ranging errors and uniform random spatial anchor node deployment ...

Indoor Positioning Using Femtocells
2011 IEEE Vehicular Technology Conference (VTC Fall), 2011The ability to locate oneself indoors on a map and navigate to desired areas has a wide range of applications. GPS and macro cell tower based positioning are not very effective indoors due to poor signal quality or limited accuracy in location estimation.

Mass-market requirements for indoor positioning and indoor navigation
2010 International Conference on Indoor Positioning and Indoor Navigation, 2010The next step in location services will be repeating the success of location services in outdoor use for navigation and local search in the indoor environment. In order to make indoor positioning and navigation reality in large scale not only compelling business opportunities must be present, but also the technology must be low-cost, low-power, have ...

Towards fully organic indoor positioning
Proceedings of the Fifth ACM SIGSPATIAL International Workshop on Indoor Spatial Awareness, 2013Indoor positioning systems based on fingerprinting techniques generally require costly initialization and maintenance by trained surveyors. Organic positioning systems aim to eliminate these deficiencies by managing their own accuracy and obtaining input from users and other sources.

Indoor Position and Orientation for the Blind
2009This work proposes the study and design of mobile interfaces to identify the position and orientation of blind people in closed environments. Through this development we seek to reach a consensus on the use of a certain technology that would allow for the identification of the position and orientation of people within a closed space (such as a school ...

There is an increasing demand for indoor positioning systems as location based services are becoming more and more widespread. However, this field of research has not yet achieved the same success as that of outdoor positioning. The objective of this project was to implement an indoor positioning system relying on Bluetooth technology, and to integrate

This chapter studies WiFi based wireless positioning in complex indoor environments. WiFi positioning makes use of the infrastructure (WiFi access points) widely deployed in indoor environments such as office buildings, teaching buildings, hospitals, and shopping centers. It is also a fact that WiFi technology has been adopted in billions of electronic
