| Abstract | This paper presents the main results of a feasibility study aimed at defining the antenna subsystem of a European DBS satellite. The antennas of the satellite radiate a large number of channels over seven multinational, partially overlapping, coverages. The mass and volume optimization requires the minimization of the number of antennas and therefore each antenna of the subsystem must produce more than one coverage. A solution based on multiple contoured beam configurations is presented. Coverage overlapping is obtained by horn sharing whilst beam isolation is provided through frequency diversity and/or polarization discrimination. |

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.
