| Abstract | High demands on mobile user positioning cannot be satisfied by single navigation system. The paper proposes multi system solution which utilizes navigation and communication systems and signals. The experimental software receiver is described as development tool of such combined system. The proposed receiver consist of three GNSS RF front ends of bandwidth of 24 MHz tunable to any navigation frequency from 1 to 2 GHz and one DVB-T(H) tuner. The programmable receiver hardware is based on FPGA and PC workstation which communicate each other via Gigabit Ethernet. In the second part of this paper we are presenting methods of estimation of time of arrival of OFDM (Orthogonal Frequency Division Multiplex) signal. Described estimation algorithm is used in the DVB-T(H) (Digital Video Broadcasting - Terrestrial) receiver which can be used for navigation or for support of satellite navigation receivers. The last part of this paper describes our results of experiments with DVB-T(H) navigation. They were obtained in various environments (urban, suburban, etc.) including indoor environment. |

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.
