| Abstract | The main factor leading to decline in geomagnetic navigation accuracy is the carrier magnetic field. Based on analyzing the geomagnetic measurement error which caused by UAS carrier magnetic interference geomagnetic field, lead the 12 coefficient compensation model into UAS' compass deviation, which used in the geomagnetic matching navigation on small gesture. In the static condition, use the non-magnetic turntable respectively to obtain magnetic data of UAS in the range of ± 30° attitude angle, with interference source or without. The data analysis shows that through the compensation, the error variance of carrier heading angle in ± 5° range is from 2.174° down to 0.350°, and in the rest angle the heading angle's error variance is from 2.282° down to 0.732°. It satisfies the requirements that the flight course stability should be better than ± 3° when a certain type of UAS in large angle attitude flies. |

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.
