| Abstract | Sensor registration deals with the correction of sensor biases, and the registration error is vital in multiple sensor systems in order to carry out data fusion. This paper provides a new real time algorithm for three dimensional (3D) asynchronous sensor bias compensation based on decentralized fusion architecture. Firstly, the bias model and the bias estimation method for 3D asynchronous sensors with sensor location uncertainty are presented, and then the bias compensation is done considering the effect of the variance of bias estimates that is generally ignored in current literatures. Finally, four bias compensation algorithms, including compensation with the variance of bias estimates, compensation without it, perfect compensation and no compensation, are compared by Monte Carlo simulation. The simulation results show that tracking performance is significantly improved with the bias compensation using the variance of bias estimates compared with the bias compensation omitting it, when there are more uncertainties in bias estimation. |

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.
