论文摘要
空降平台,例如无人机,气球和气柱,最近对通信部门引起了极大的兴趣。自由空间光通信(FSOC)系统可以使用紧凑和轻巧的光学终端以高数据速率(以上1 Gbps)无线提供信息。因此,机载FSOC系统一直是最近感兴趣和活动的主题,包括Google Loon和Facebook Aquila等新兴项目。 FSOC系统的主要技术挑战之一是指向,获取和跟踪(PAT)功能的严格要求,以确保发射机和接收器之间的可靠传输,这是由于狭窄的光束宽度和机载平台的运动。通过识别和验证涉及此问题的改进技术,我们开发了螺旋桨和风引起的振动的简单模型,并研究了这些振动对平流层运行的FSOC系统性能的影响。
Airborne platforms, such as drones, balloons, and aerostats, have recently gained considerable interest in the communication sector. Free-space optical communication (FSOC) systems can deliver information wirelessly at high data rates (above 1 Gbps) using compact and lightweight optical terminals. Thus, airborne FSOC systems have been a recent subject of interest and activity, including emerging projects such as Google Loon and Facebook Aquila. One of major technical challenges of FSOC system is the stringent requirement of pointing, acquisition, and tracking (PAT) capability to ensure the reliable transmission between the transmitter and receiver, due to narrow beam width and movement of airborne platforms. By identifying and validating improvement techniques dealing with this issue, we developed simple models of propeller and wind induced vibrations and investigated the effect of those vibrations on the performance of FSOC systems operating in the stratosphere.
