| Abstract | This paper describes the latest on-orbit International Space Station (ISS) electrical power system (EPS) operational control capabilities including autonomous functions, override capabilities, operational constraints and their verification. The ISS requires the ability of the vehicle to detect, isolate and recover "functions required for 24 hour autonomous operation" without crew or ground intervention. This results in a necessity to design and develop autonomous operations without routine commanding and override of specific automation. The paper covers the autonomous tiers of control, the manual control strings provided to the flight crew and ground for operational flexibility, operation procedures and the verification of EPS flight hardware and software. It covers how the EPS operations are performed by means of hardware, software, firmware and procedures. The EPS control domains are defined by a functional decomposition of Space Station capabilities and the allocation of those functions to a particular EPS hardware, software, firmware capability or to a control tier. In the paper, all the control domains within the EPS sub-system are defined to include the autonomous, manual and system constraints providing full coverage of EPS functionality. |

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.
