使用CubeSat软件定义无线电子系统实现无线测距和同步
Towards Wireless Ranging and Synchronization using CubeSat Software-Defined Radio Subsystems
摘要：
研究了一种利用商用软件无线电有效载荷实现小卫星（特别是立方体卫星）无线测距和同步的方法。该方法仅依赖于可编程逻辑配置和处理系统软件。不需要对有效载荷进行硬件修改或添加。初步实施的实验评估显示，基于飞行时间的测距测量的标准偏差在1厘米的顺序，这使得分布式卫星系统任务的概念感兴趣。
英文摘要：
An approach towards wireless ranging and synchronization using commercial of-the-shelf software-defined radio payloads for small satellites, esp. CubeSats is studied. The approach only relies on the programmable logic configuration and processing system software. No hardware modifications or additions to the payloads are necessary. Experimental evaluation of the initial implementation shows a standard deviation of time-of-flight-based ranging measurements in the order of 1 cm, which renders the concept of interest for distributed satellite system missions.
