Abstract | The relative position between magnetic target and the device, which is installed on vehicle under water, is determined by measuring magnetic field magnitude and its gradient of target on condition that geomagnetic field anomaly can be viewed as a magnetic dipole object. The errors of measuring magnetic field and its gradient caused by nonorthogonality between axes, different sensitivity of each axis, and installation center departure of magnetometers are analyzed in theoretically. These errors of magnetic field magnitude and its gradient can act effect on the localization precision of underwater vehicle, which is analyzed theoretically and simulation numerically. These results show that magnetometer performances such as nonorthogonality between axes, and different sensitivity of each axis have the remarkable influence on the localization precision. |

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.
