Application of GPRS composite relay equipment in ship positioning

船舶定位中具有随机振荡性,采用传统的传感融合跟踪定位方法容易出现漂移失真,提出一种采用GPRS复合中继定位的船舶定位方法。采用GPRS复合中继节点部署方法进行船舶无线传感网络设计,结合BPSK调制方法构建船舶定位的多径传输链路模型,采用GPRS复合中继设备进行中断保护控制,构建船舶定位系统的电路系统模型,采用随GPRS通信和中继传输控制方法实现船舶定位优化。仿真结果表明,采用该方法进行船舶定位的准确性较好,定位控制过程具有较好的稳健性。

Because of the random oscillation in ship positioning,the traditional sensor fusion tracking method is prone to drift distortion.This paper presents a ship positioning method based on GPRS complex relay positioning and the design of ship wireless sensor network using GPRS composite relay node deployment method.Combined with BPSK modulation method,the multi-path transmission link model of ship positioning is constructed,and the interrupt protection control is carried out by using GPRS compound relay equipment,and the circuit system model of ship positioning system is constructed.The ship positioning optimization is realized by means of GPRS communication and relay transmission control method.The simulation results show that the accuracy of the method is good and the positioning control process is robust.
