Abstract | In this paper, analytical error characteristics of GPS compass which determines heading and elevation of the vehicle using carrier phase measurements from two antennas is given. The derived result gives clear analysis of error statistics on attitude determination using GPS carrier phase measurement. It shows the accuracy of measured attitude relies on satellite geometry, performance of receiver, baseline length, baseline configuration and nominal attitude of vehicle. It is also shown that to obtain more precise heading, longer baseline along the vehicle is preferred and the accuracy of heading is always better than that of elevation since the vertical measurement uncertainty caused by geometry of satellites affects only on that of elevation. These results can be applied to basic directions for attitude determination: to what direction should the baseline be located to minimize the error, which satellites should be selected to minimize the error. These must be important and useful pre-information in attitude determination problem. An application to real data shows that the predicted error by the proposed method coincides with that of experiments. |

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.
