| Abstract | In this paper we propose an architecture for multi-satellite control systems and an optimization procedure for mission operations. The proposed multi-satellite control system architecture is obtained by structuring existing mission control systems into three organically connected components. : (1) the ground station responsible for the mechanical parts, (2) the users responsible for the overall management, and (3) the mission control element responsible for the overall scheduling and software operation. In addition, we present a mission scheduling optimization procedure involving numerous satellites and ground stations. The algorithm assumes the scheduling period time, the value and allocation time of the guidance parameter file for attitude control, and the mission value and image downlink allocation time. The visibility time between a ground station and satellites is calculated by simulation using the satellite tool kit. Hence, the scheduling problems can be treated as knapsack problems where the visibility time is analogous to the knapsack and the missions are considered to be the items. To solve the multi-mission scheduling problem, we applied the dynamic programming and greedy algorithms. We compared and analyzed the two algorithms. |

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.
