Accurate and robust positioning technology is expected to promote management level and service efficiency in various industrial\napplications.The strap-down inertial navigation system (SINS) approach has short-termaccurate positioning performance, but the\nSINS is known for its accumulative error over time. Meanwhile, wireless sensor networks (WSN) approach can keep the mobile\ntarget on effective tracking after a long time monitoring, but the WSN may have large positioning error in certain areas. In order to\nmake the positioning method allow profit from their advantages, this paper proposes a positioning technology using SINS approach\nin conjunction with WSN approach. The measurement parameters by SINS and WSN approaches are used. Then the SINS, anchor\nnodes, mobile tags, XBee, and computer are applied to design the positioning system. The estimation results indicate that the\nproposed method can make up for the shortcomings by pure SINS or WSN method and can be available for some accurate and\nrobust applications.
