| Abstract | Galileo program is now approved by the European concerned government. The activities related to GSTBV2 experimental satellite as well as the implementation of the In Orbit validation phase have been started. Atomic clocks represent critical equipment for the satellite navigation system and clocks development has been continuously supported by ESA. The first related ESA contract for a RAFS (rubidium atomic frequency standard) was first initiated in 1996. RAFS is today one of the baseline clock technology for the Galileo navigation payload. This presentation gives a general overview of the RAFS development and evolution so far. It also provides updated information on the measurement results regarding clock frequency stability under simulated space environment as: i) vacuum coupled with temperature variation ii) electromagnetic perturbation iii) radiation variation (orbit cycle simulation) and total cumulated dose. Furthermore, measurement related to the capability of the clock to survive the vibration environment during launch without damage is addressed. |

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.
