When using GNSS navigation for final approach guidance of aircraft to a landing site, the only systems currently available are differential GNSS with additional integrity data called augmentation systems. These work well when the landing site is fixed in space and well surveyed. In all other cases, augmentation systems are difficult to use. Here, we propose relative navigation based on GNSS double difference measurement to accomplish the same task, but also onto moving landing platforms or at unsurveyed locations. We call this the Beacon Landing System. Furthermore, we show long term measurement data confirming the sub-meter accuracy and results from flight tests. During the flight test we successfully used the relative navigation for aircraft guidance.

当使用 GNSS 导航将飞机最后进近引导至着陆点时，目前唯一可用的系统是具有称为增强系统的附加完整性数据的差分 GNSS。当着陆点固定在太空中并经过良好调查时，这些方法效果很好。在所有其他情况下，增强系统都难以使用。在这里，我们提出了基于 GNSS 双差测量的相对导航来完成相同的任务，但也可以在移动的着陆平台或未调查的位置上进行。我们称之为信标着陆系统。此外，我们展示了长期测量数据，证实了亚米级精度和飞行测试结果。在飞行测试中，我们成功地将相对导航用于飞机制导。
