| Abstract | MIL-STD-1553's one megabit-per-second data rate is adequate for the vast majority of command and control applications within avionics systems but there are emerging systems that require higher data rates. Implementing higher data rate communication generally requires the use of high speed cables. Installing new cabling in legacy aircraft can be cost prohibitive. This work explores the possibility of extending the bandwidth of MIL-STD-1553 by implementing a broadband communication system over legacy 1553 cabling. Various measurement techniques were employed by Data Device Corporation to characterize the performance of a typical 1553 network and each of its major elements. The results of these measurements are used to predict the theoretical capacity of the network using Shannon's equation. The analysis includes characterization of the signal level, noise level, and bandwidth of various channels within a MIL-STD-1553 network. The goal of the research is to quantify the amount of unused capacity within a MIL-STD-1553 system. This work does not present methods of implementing a broadband system but rather provides a framework and initial results for evaluating the feasibility of such a system. The findings presented in This work suggest that there are hundreds of megabits of theoretical capacity available in a MIL-STD-1553 network. The actual achievable data rates would depend on a number of factors including the waveform (or signal coding scheme), and the 1553 bus topology (i.e. bus length, stub length, and number of couplers). The attractiveness of a high performance 1553 system stems from the reuse of legacy cabling and the ability to add new capability to existing platforms without disturbing existing hardware and software. |

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.
