| Abstract | The theoretical study due to the giant magneto-impedance (GMI) effect of Co-rich amorphous wire sensor is presented. As a practical device, this sensor may be used to sense the Earth's magnetic field and to provide a measure of the attitude of a moving vehicle. It is proposed a multivibrator bridge should be adopted as the structure module. The measuring principle of the sensor is stressed, which is accomplished by means of establishing corresponding mathematic model. In sequence, with a numerical simulation being carried out, a good linear characteristic between voltage and measured field in the range of $plusmn3O_{e}$ is achieved, which demonstrates this sensor is a linear one, and it is capable of measuring weak signal of magnetic field. In addition, the application of this sensor for the attitude and heading reference system (AHRS) with the micro inertial measurement units (MIMUs) is studied, providing an effective method for low cost solid-state AHRS with high accuracy theoretically. |

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.
