Implementation of Mobile Target Positioning Technology Integrating SINS with WSN Measurements

Abstract EN

Accurate and robust positioning technology is expected to promote management level and service efficiency in various industrial applications.

The strap-down inertial navigation system (SINS) approach has short-term accurate positioning performance, but the SINS is known for its accumulative error over time.

Meanwhile, wireless sensor networks (WSN) approach can keep the mobile target on effective tracking after a long time monitoring, but the WSN may have large positioning error in certain areas.

In order to make the positioning method allow profit from their advantages, this paper proposes a positioning technology using SINS approach in conjunction with WSN approach.

The measurement parameters by SINS and WSN approaches are used.

Then the SINS, anchor nodes, mobile tags, XBee, and computer are applied to design the positioning system.

The estimation results indicate that the proposed method can make up for the shortcomings by pure SINS or WSN method and can be available for some accurate and robust applications.
