| Abstract | Aimed at the metrology support requirements of weapons found north orientation equipment, a gyro north-seeker calibration system is designed. The system uses one plane mirror and two 1 m collimators to set up three north benchmarks at the same time, and they are assigned to the north. The accuracy of the introduced three northward azimuthal angles is as follows: ±0.20″, ±0.18″, ±0.17″. Between the three north benchmarks, the mutual check function can be realised. The system can realise the calibration of the gyro theodolite and gyro north-seeker with auto-collimation function and no auto-collimation function. The composition and working principle of the system are described in detail. After examination, the north-seeking precision accuracy of the system is 3″ (k = 2). It satisfies the metrological calibration of the gyro theodolite and gyro north-seeker whose north-seeking precision is below 12″. Through practice, the system is accurate, stable and reliable. |

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.
