| Abstract | This paper presents the design of a guidance, navigation and control (GNC) system for formation flying satellites in low Earth orbit. An innovative estimation approach employs a common extended Kalman filter (EKF) for the spaceborne autonomous control mode, which includes the J2 perturbations. A nonlinear least squares method is adopted for the ground-in-the-loop control mode. As a result, the navigation system can provide relative orbit information with a position accuracy of 3cm and a velocity accuracy of 0.2mm/s. The coordination control concept is detailed based on the relative orbital elements. Therefore, a three impulse method for configuration control is put forward which is simple and easy for engineer implement. Finally, an overview of the processor-in-the-loop testbed is given, which enables a seamless transition to real-time software simulations as well as hardware-in-the-loop simulations. The validation shows the simplicity and effectiveness of the navigation and control 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.
