Precise Positioning System of Ship Interior Based on UWB Ultra Wideband Technology

ABSTRACT Zhang, K.; Shen, C.; Gao, Q.; Zheng, L.; Wang, H., and Li, Z., 2018. Precise positioning system of ship interior based on UWB ultra wideband technology. In: Liu, Z.L. and Mi, C. (eds.), Advances in Sustainable Port and Ocean Engineering. Journal of Coastal Research, Special Issue No. 83, pp. 908–912. Coconut Creek (Florida), ISSN 0749-0208. A new ship indoor accurate positioning system was proposed. Firstly, the UWB ship indoor positioning system of power module, MCU module, UWB module and chip selection of memory module were given. The hardware design of system label / micro base station was completed. Then, based on the UWB localization algorithm, the time difference of arrival (TDOA) improved algorithm using reference tags auxiliary information was proposed. The software design process of system label / micro base station was completed. Experimental result shows that this system has high positioning accuracy. and the low time delay of receipt signal.
