| Abstract | In this paper, we present a novel approach to continuous remote sensing of Earth. The proposed concept "GLORIA" drastically enhances the ability of scientists to study the Earth in a manner not possible before. The proposed system is based on a constellation of few geostationary, radar transmitter satellites and several low Earth orbiting synthetic aperture radar receiver satellites. Just as the sun is the radiation source for optical remote sensing, transmitters of microwave energy in a geostationary orbit provide the energy for radar remote sensing. Advantages of such a constellation lie in (1) a much larger number of observables, due to multi-static measurements, which significantly enhances the accuracy of retrieval algorithms, 2) the distribution of failure risk is by eliminating total system failure if a single satellite stops operating, 3) simple modular system design of small satellites through separation of transmitters and receivers (reducing weight, cost and power consumption by each satellite), and 4) flexibility in operation, that is, the receivers can be configured for different modes. |

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.
