5月15日，记者从国防科技大学获悉，该校电子科学学院教授王飞雪团队利用天线抖动增加卫星高精度 测量中的信息量，研发了一种消除多径误差的新机制，并在全球首次成功以微小抖动消除了多径误差， 为复杂遮挡环境下的低成本高精度卫星导航创造了更大的可能。该成果日前在线发表于国际期刊《通讯 ·工程》。 传统高精度卫星导航主要依赖阻尼环天线等昂贵的高端监测天线，以被动抑制用户接收到卫星直达信号 以外的反射信号带来的多径误差。但在城市峡谷、林区或室内等复杂遮挡环境中，这类多径信号干扰依 然无法被彻底消除。与此同时，高端监测天线等高成本设备也难以大规模部署。 团队将各种天线抖动模式统一映射到线性抖动模型中，推导出了最小抖动幅度理论公式，并基于该公式 计算，研发出了一套直线抖动装置。它可兼容于现有车载天线和手持天线，无需对天线内部结构进行任 何改动。团队通过静止高精度监测天线（成本约5万元）与抖动普通车载天线（成本约7元）的对比实验 发现，两者二维定位精度基本相同。 该方法不仅为智慧交通、自动驾驶、无人机巡检等场景提供了低成本、高可靠的卫星定位新解决方案， 还研发出了可灵活安装于各类现有天线、无需改变接收机硬件的抖动模块，有望大幅 ...
