| Abstract | In a GPS/IMU integrated navigation system, problems are often encountered during periods of low-observability of heading considered essential in many applications such as antenna steering platforms, airborne navigation, swarm navigation, mobile mapping and harbor navigation. This paper proposes the use of a GPS/MEMS-based-IMU with a single GPS baseline measurement update in an EKF framework for an improved heading performance. The single GPS baseline update makes use of GPS-L1 only carrier-phase measurements from two antenna's mounted 1 m apart along the direction of motion of the platform. The epoch-to-epoch double-difference carrier-phase measurements formed is resolved for the integer ambiguity set and is incorporated directly in an EKF measurement update. The performance of the navigation system is demonstrated using data collected in an urban environment with sensors rigidly mounted on the rooftop of a van. |

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.
