There are currently over a dozen artificial satellites called amateur satellites in orbit. These satellites provide unique opportunities for science and engineering education. I investigated possible educational programs using amateur satellites for K-12 graduate students to study physics, radio communication, spacecraft technology and space environment, I proposed the following original teaching materials and confirmed their remarkable educational effectiveness.(1) Doppler effect and spacecraft velocityAmateur satellites are suitable for demonstration and observation of the Doppler effect. Radio beacon waves transmitted from amateur satellites exhibit considerable Doppler shift which is proportional to relative satellite/observer velocity. Doppler shift measurements for circular orbiting amateur satellites yield the magnitude of relative velocity which is in good agreement with theoretical prediction.(2) Kepler's law and spacecraft motionAnother educational use of radio beacon waves is to demonstrate that spacecraft orbiting around the Earth are subject to Kepler's law. Measurement of the visible time for a high-elevation pass by hearing the beacon yields a reasonable orbital period which is elementary derived from a theoretical calculation.(3) Equipments for receiving telemetry and whole orbit dataMost of amateur satellites broadcast telemetry and various data such as whole orbit data. I designed a simple and inexpensive equipment for receiving these data. Students are able to directly receive and display real time telemetry by using this equipment linked to their personal computers. I developed a new type of demodulator in order to capture, decode and store UoSAT-2 whole orbit data. By analyzing telemetry and whole orbit data stored in PC, students are able to have much understanding of spacecraft status such as solar battery's performance and of space environment such as Earth's magnetic field.

目前，轨道上有十几个称为业余卫星的人造卫星。这些卫星为科学和工程教育提供了独特的机会。我研究了可能的教育计划，使用业余卫星供K-12研究生学习物理学，无线电通信，航天器技术和太空环境，我提出了以下原始教材，并确认了它们出色的教育有效性。适用于示范和观察多普勒效应。从业余卫星传播的无线电信标波显示出相当大的多普勒移位，与相对卫星/观察者速度成正比。圆形轨道业余卫星的多普勒偏移测量结果产生的相对速度的幅度与理论预测非常吻合。（2）开普勒定律和航天器的骑行动态使用无线电信标波的教育是证明，航天器在地球周围绕地球上的飞船构成了开普勒的kepler's of Kepler's obbe法律。通过听到信标通过听到的高海拔通行时间的可见时间测量得出一个合理的轨道时期，这是从理论计算中得出的基本时期。（3）接收遥测和全面轨道datamost的设备整个轨道数据。我为接收这些数据设计了一种简单且廉价的设备。学生可以使用与个人计算机相关的设备直接接收和显示实时遥测。我开发了一种新型的解调器，以捕获，解码和存储UOSAT-2整个轨道数据。通过分析PC中存储的遥测和整个轨道数据，学生可以对航天器状态有很多了解，例如太阳能电池的性能和太空环境，例如地球的磁场。
