To address the issues of electromagnetic interference, multipath effect, and the adaptability shortcomings of existing systems in ZigBee wireless sensor network positioning systems under the complex electromagnetic environment of ships, this paper conducts research on a shipborne ZigBee positioning system for complex electromagnetic environments. The multi - dimensional coupling effects of the ship's electromagnetic environment on ZigBee positioning are analyzed. Then, a three - tier system architecture of "perception layer - network layer - application layer" is designed, and the anti - interference hardware selection design and software modular development are completed. Furthermore, a multi - parameter positioning optimization algorithm integrating RSSI, TOA, and TDOA is proposed. Simulation verification and comparison of multiple algorithms in terms of average positioning error, robustness coefficient, and positioning stability are carried out, which verifies the excellent positioning performance of the proposed algorithm in complex electromagnetic environments.
