论文摘要
随着空域中无人驾驶汽车（UAV）的数量的越来越多，确保飞机不会碰撞对进一步的技术开发至关重要。在这项工作中，我们提出了一个新的无人机，在空中碰撞附近（UNMAC）安全量i）机身大小，ii）定位精度，iii）无人机速度/速度和iv）无线技术能力。基于UNMAC，我们证明可以通过使用UAV-TO-UAV（U2U）通信来降低UAV间的分离距离，而安全水平保持不变。此外，这项工作表明，下一代远程ID消息应包含其他信息（即，估计的本地化错误，对于某些应用程序，移动方向）。由于远程ID的频繁广播可以进一步降低分离距离，因此我们确定了5G NR Sidelink，Wi-Fi和蓝牙是用于U2U通信的合适候选者。
As the number of Unmanned Aerial Vehicles (UAVs) in the airspace grows, ensuring that the aircraft do not collide becomes vital for further technology development. In this work, we propose a new UAV Near Mid-Air collision (uNMAC) safety volume taking into account i) Airframe size, ii) Localization precision, iii) UAV speed/velocity, and iv) wireless technology capabilities. Based on uNMAC, we demonstrate that inter-UAV separation distances can be reduced by using UAV-to-UAV (U2U) communication while the safety levels remain unchanged. Moreover, this work shows that next-generation Remote ID messages should contain additional information (i.e., estimated localization error and, for some applications, movement direction). As frequent broadcasting of Remote ID can further reduce the separation distances, we identified 5G NR Sidelink, Wi-Fi, and Bluetooth as suitable candidates for U2U communication.
