| Abstract | Mahdasht Satellite Receiving Station (MSRS) has been using 10 m reflector antenna to communicate with LEO satellite at S-band (2.2–2.3 GHz) and X-band (8–8.4 GHz). Presently, antenna pointing operates in program tracking. Pointing accuracy under program tracking conditions is in the neighbourhood of 0.2°. This is acceptable at S-band, but not enough at X-band. Due to the narrow beamwidth at X-band, it is important to improve pointing accuracy significantly (0.05°). Monopulse antenna tracking is one approach that provides tracking accuracy at high-frequency bands. This study presents mathematical model and simulation of monopulse pointing system using a novel analytic approach. Monopulse error signals are calculated using the proposed model while considering the kinematic equations with the assumption of the Gaussian radiation pattern for reflector antenna. The simulation results are verified by using a real (MSRS antenna) monopulse tracking system in X-band frequency (8.2 GHz). The measurement and simulation results demonstrated the azimuth and elevation pointing errors are valid in 3 dB beamwidth. |

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.
