| Abstract | GPS satellites transmission consists of two pseudorandom noise codes, modulated on two carriers. For position determination of a GPS receiver on the earth two parameters, satellite position and pseudo ranges of each Satellite Vehicle are to be estimated by decoding the Navigation message from each satellite which depends on the Carrier to Noise Ratio (C/N0) at the receiver. GPS employs spread spectrum CDMA therefore the power levels of received signals play important role in design of GPS receiver. If the received power level from one SV is higher than the other then the received signal of the other satellites get masked and experiences ‘Near and Far’ effect hampering detection. In this paper, the received C/N0s of all SVs are modeled over the low latitude region for accurate decoding of composite GPS signal. The modeled parameters are validated with the dual frequency GPS receiver measurements located at Andhra University College of Engineering (Latitude/Longitude $17.73^{0}$ $N/83.32^{0}$ E). |

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.
