Abstract: The many rich applications based on sensors have caused widespread concern on the location awareness of sensor nodes. One issue to address is how to dynamically deploy a wireless localization system in a positioning, navigation and timing (PNT) deficient area without positioning signal coverage in application scenarios such as cave exploration and emergency rescue situations. In order to support the task of dynamic deployment, this paper proposes a localization system based on wireless sensor networks (WSN). The proposed system is composed of two parts: a management center and a WSN. Using the proposed delay corrected extended Kalman filter (DCEKF) algorithm, the hardware delay bias correction and the localization and tracking of each node are realized. It is proved by numerical simulation and hardware experiments that the system can obtain high-precision positioning and tracking results of nodes in the process of dynamic deployment in PNT deficient areas with great robustness and flexibility.
