| Abstract | Focusing on the limitations of the low-cost strapdown inertial navigation system (SINS) which just can provide accurate navigation information during a short time, and considering the passive navigation demand in war, a low-cost SINS/Magnetometer (MR) tightly-coupled navigation system based on the Kalman filter is proposed. Because MR is easily affected by the magnetic field around to generate the magnetic deviation, the tightly-coupled Kalman filter is used to evaluate and compensate the magnetic deviation parameters through the WMM2010 magnetic model and the horizontal attitude provided by the SINS. As a result, the accuracy of heading attitude output by the MR has increased. Furthermore, the precision of the low-cost SINS/MR tightly-coupled navigation system is improved. Finally, the field-test over 25 minutes verifies the algorithm: the position, velocity and heading errors provided by the tightly-coupled navigation system are less than 10 m, 0.2 m/s and 0.3 deg. So the system offers significant contribution to the practical engineering application. |

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.
