Based on the MGT positioning method, the performance of combined magnetic beacon is studied. The unit size of beacon is designed as D = 2 cm and L = 8 cm, the performance of different structure magnetic beacons combined have been studied and compared in detail, results show that the magnetic field intensity of cross structure is about 30000nT higher than the orthogonal structure which have generated sine waves. According to the TLS to filter the signal based on the regular tetrahedral gradient tensor measurement array. In the laboratory environment (Bearth=46157nT) to validate the model in this paper, the experimental results show that the array of two identical cross-combined permanent magnets will increase the magnetic induction value at the same distance by 1.7 times and the max-average positioning error on the 6 experimental paths is 1.52m. The implications of these findings particularly regarding the array rotation combined magnetic beacon may be useful for the high-precision magnetic position systems.

基于旋转组合磁信标的MGT目标定位方法研究

基于MGT定位方法,研究了组合式电磁信标的性能。将信标的单位大小设计为D  = 2 cm和L  = 8 cm,已研究并比较了不同结构的磁性信标的性能,并进行了详细比较,结果表明,十字形结构的磁场强度比C的高30000nT。产生正弦波的正交结构。根据TLS对信号进行滤波,基于规则的四面体梯度张量测量阵列。在实验室环境(B= 46157nT)来验证该模型,实验结果表明,两个相同的交叉组合永磁体的阵列将使相同距离处的磁感应值增加1.7倍,并且在6个实验中的最大平均定位误差路径是1.52m。这些发现的含义,特别是关于阵列旋转组合磁信标的含义,可能对高精度磁定位系统很有用。
