一种多天线北斗导航定位技术的标定方法

A Calibration Method for Multiple Antennas Beidou Navigationand Positioning Technology

岸边装卸设备和码头堆积集装箱存在大量金属反射面,会干扰卫星的高精度定位状态。提出一种多天线布置的方案,将北斗天线分布在自动化导引车的4个角,再借助单差载波相位测量计算得出天线的位置坐标,即可由已知的天线位置坐标获得接收机的位置坐标。通过应用验证,卫星导航定位的抗干扰能力显著提升,可保障自动化导引车在复杂环境中的稳定运行,实现自动化码头装卸系统质量提升。

There are a large number of metal reflective surfaces in the shore-side handling equipment and terminal stacked containers,which will interfere with the high-precision positioning state of the satellite.A multiple antennas arrangement is proposed to distribute the Beidou navigation antennas in the four corners of the automated guided vehicle,and then the position coordinates of the antennas are calculated with the help of the single differential carrier phase measurement,which can be used to obtain the position coordinates of the receiver from the known antenna position coordinates.Through the application verification,the anti-interference ability of satellite navigation and positioning is significantly improved,which can guarantee the stable operation of the automated guided vehicle in the complex environment,and realize the quality improvement of the automated terminal handling system.
