【摘要】：为了提高偏振光导航定位的可靠性和实时性,提出了一种利用多方向偏振光的自主式导航定位方法并搭建了样机。通过样机多方向阵列结构中的偏振光导航传感器实时检测天空多个方向的偏振光信息,并对这些信息进行优选和融合处理,计算得到更加可靠且准确的太阳空间位置。最后根据太阳空间位置,结合时间和地磁场分布信息,计算样机所在位置的经纬度,实现实时定位。基于可视化软件LabVIEW编写样机上位机程序,能够实时采集样机中传感器数据,同步处理计算且实时显示载体地点经纬度,数据更新率可达10Hz。静态测试结果表明,定位样机性能稳定,经度方向上的定位精度为±0.4°,纬度方向上为±1.2°,定位精度较高,可应用于实际导航。
[Abstract]:In order to improve the reliability and real-time performance of polarized light navigation, an autonomous navigation and positioning method using multi-directional polarized light is proposed and a prototype is built. The polarizing light information in multiple directions of the sky is detected by the polarizing light navigation sensor in the multi-directional array structure of the prototype, and the information is selected and fused to obtain a more reliable and accurate position of the sun space. Finally, according to the position of the sun space and the information of time and geomagnetic field distribution, the longitude and latitude of the prototype are calculated, and the real time positioning is realized. Based on the visual software LabVIEW, the upper computer program of the prototype can be compiled, the sensor data in the prototype can be collected in real time, and the latitude and longitude of the carrier can be displayed in real time. The update rate of the data can reach 10 Hz. The static test results show that the positioning precision is 卤0.4 掳in longitude direction and 卤1.2 掳in latitude direction.
