纳米卫星是用于地球传感研究的紧凑、低功率、廉价的低地球轨道卫星。地面控制和与卫星的通信是使命成功的关键;然而，目前的地面监测基础设施不适合纳米卫星的实施。在这项工作中，我们考虑利用商业蜂窝通信网络来操作地面通信部分的可行性。这在可用性、信号带宽和廉价硬件方面提供了几个优点。影响该方法实用性的问题是传播距离、空间传播环境以及补偿无线电信号的衰减、延迟和干扰所需的信号处理。提出了天线设计、信号处理和控制方面的解决方案。
Nano-satellites are compact, low power, inexpensive, low earth orbit satellites intended for earth sensing research. Ground control and communication with the satellites is key to mission success; however, current ground monitoring infrastructure is ill-suited to nano-satellite implementations. In this work we consider the feasibility of exploiting commercial cellular communications networks to operate the ground communications segment. This offers several advantages in availability, signal bandwidth, and inexpensive hardware. Issues affecting the practicality of the approach are propagation distances, the space propagation environment, and the signal processing required to compensate for the attenuation, delay, and interference of the radio signals. Solutions in antenna design, signal processing and control are proposed to address the limitations.
