近年来，纳米卫星在学生和年轻研究人员中越来越受欢迎。这是因为纳米卫星具有类似于大型卫星的能力，但尺寸很小。它很容易制造，并且可以使用低成本设备制造。然而，制造纳米卫星的主要问题在于其通信系统。纳卫星通信系统必须可靠地从地面站向纳卫星发送信息，反之亦然。在本文中，我们提出了一个使用树莓派的纳米卫星通信系统，以及一个使用GNURadio编程的HackRF SDR。从测试过程来看，采用GMSK调制方案，地面站可以很好地将文本数据传输到纳卫星上。该通信系统还具有可重构性，这意味着许多调制方案和算法可以在不改变硬件的情况下容易地实现。
In recent years, nano satellite has gained popularity among students and young researchers. The reason is that, nano satellite has the ability similar to larger satellite, but in tiny compact size. It is easy to made and can be made using low cost devices. However the main problem in making a nano satellite is in the its communication system. Nano satellite communication system has to be reliable to send information from ground station to nano satellite or vice versa. In this paper, we propose a nano satellite communication system using Raspberry Pi, and a HackRF SDR which is programmed using GNURadio. From the testing process, the text data can be transmitted properly from ground station to nano satellite using GMSK modulation scheme. This communication system also has ability to be reconfigured, which means many modulation scheme and algorithm can be implemented easily without changing the hardware.
