| Abstract | In recent years there has been a large increase in the use of wireless localization for a broad range of commercial and consumer applications, including to enhance safety and productivity, provide location based services and entertainment. Accurate outdoor localization is provided using global navigation satellite systems (GNSS) such as the Global Positioning System (GPS), while indoor localization is typically obtained using received signal strength (RSS) of access points in wireless networks and has low accuracy. Accurate localization in indoor and GNSS denied spaces remains a challenge in general. This paper presents a low-cost system for accurate localization in challenging environments that uses the fusion of Time-of-Flight (ToF) wireless ranging and micro-electro-mechanical (MEMS) inertial sensors. The key contributions of this paper are a fusion concept and experimental results using a deployed system in outdoor and indoor environments. Compared to the use of the Wireless Ad-hoc System for Positioning (WASP) alone, the fused system is demonstrated to obtain sub-meter accuracy with a much lower update rate, enhancing system scalability and availability, and enabling the system to operate with lower power consumption. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
