| Abstract | As free inertial pedestrian navigation systems with foot mounted inertial mobile unit mature, it becomes feasible to conceive a sufficiently accurate derived solution for assessing other indoor navigation systems and assisting research activities. The design of this reference solution and the remaining challenges are at the heart of this paper. A new filter with a quaternion based state vector exploits signals (acceleration and magnetic field) and motions of opportunity for estimating the navigation solution. Quasi Static Field (QSF) updates, Magnetic Angular Rate Updates (MARU) and Angular Gradient Update (AGU) are frequently applied for mitigating the low-cost inertial sensors errors. Experimental tests performed using a post-processed GPS differential solution as reference show an average accuracy of 1.2 m over 500 m walking path: 0.5 %. Discussions about the data acquisition protocol for meeting a 1 meter horizontal accuracy within two standard deviations of the mean (95.45%) is conducted. |

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.
