Development of the "3D Observation Navigator of the Earth" as a Science education software on the International Space Station (ISS) in the new millennium.

这项研究的目的是为科学教育开发关于国际空间站活动的学习软件。我们开发了名为“人造卫星观测导航仪”的网页。在这些网页中，我们介绍了许多明亮的人造卫星，如国际空间站（ISS），SEASAT，TRMM，UARS，USERS，AJISAI等的飞行课程和时间。该网页已被用于许多小学，初中或高中的科学课。在这些卫星中，国际空间站是最亮的卫星，几乎所有的观测者都能找到它。此外，多名宇航员在国际空间站执行多项任务的事实吸引了观察者。许多人在观察了国际空间站在星夜中经过后，想知道如果他们是宇航员在国际空间站，如何看到地球。本研究的主要目的是开发从国际空间站轨道看到的地球的三维模拟软件。为了做到这一点，我们使用国际空间站的真实的时间位置计算从国际空间站的轨道要素从美国宇航局网站。地球的3D对象已经从卫星图像与测高数据。利用矩阵引擎实现了地球物体的三维显示。开发的网页标题为“地球三维观测导航仪”，目前版本的地球三维观测导航仪显示无云的地球图像。在加入气象卫星实时云图方面进行了许多技术评估，另一方面，对“人造卫星观测导航仪”进行了几项改进，其中包括预测卫星的大小。

The aim of this research is development of learning software on the activities of International Space Station for science education. We have developed web pages entitled "Observation Navigator of Artificial Satellites". In these pages, we present flight courses and times of many bright artificial satellites such as International Space Station (ISS), SEASAT, TRMM, UARS, USERS, AJISAI, etc. The web pages have been used in many science classes of elementary schools, junior high schools, or high schools. Among these satellites, the ISS is the brightest satellites and regarded to be found almost all observers. Further, the fact that several astronauts stay in the ISS for many missions attracts observers.After observation of ISS passing in the starry night, many people wonder how the earth could be seen, if they were astronauts staying in the ISS. The main purpose of this study is to develop the 3D simulation software of the Earth seen from the ISS orbit. In order to do this we used real time position of ISS calculated from the orbital elements of ISS from NASA website. The 3D object of the Earth has been made from satellite images with altimetry data. The 3D exhibition of the earth object has been operated with the Matrix-engine. The developed web pages has been entitled "3D Observation Navigator of the Earth".The current version of the 3D Observation Navigator of the Earth displays Earth images without clouds. Many technical assessments for the addition of real-time cloud images taken from meteorological satellites have been made.On the other hand, several improvements have been made for the "Observation Navigator of Artificial Satellites", which includes prediction of the magnitude of the satellites.
