Abstract

As an alternative to GPS, we focus on indoor positioning using Wi-Fi RTT (Round Trip Time), which measures the round trip time to a Wi-Fi access point. Wi-Fi RTT-based positioning has not been well studied for indoor drones. As an experimental study of indoor drone positioning using Wi-Fi RTT, this paper presents a positioning method using a combination of on-board altimeter and Wi-Fi RTT ranging, and experimental results of drone positioning when stationary and hovering to clarify the positioning accuracy in both 2.4 GHz and 5 GHz bands. This paper shows that in both frequency bands, the positioning accuracy is significantly degraded during hovering compared to stationary, and that there is no significant difference between 2.4GHz and 5 GHz bands.

利用 Wi-Fi RTT 进行室内无人机定位的实验研究
作为 GPS 的替代方案,我们将重点放在使用 Wi-Fi RTT(往返时间)进行室内定位上,它测量的是到 Wi-Fi 接入点的往返时间。基于 Wi-Fi RTT 的室内无人机定位尚未得到充分研究。作为利用 Wi-Fi RTT 进行室内无人机定位的实验研究,本文介绍了一种结合使用机载高度计和 Wi-Fi RTT 测距的定位方法,以及无人机静止和悬停时的定位实验结果,以明确在 2.4 GHz 和 5 GHz 频段的定位精度。本文表明,在这两个频段中,悬停时的定位精度比静止时明显降低,而 2.4 GHz 和 5 GHz 频段之间没有明显差异。
