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“人造卫星观测导航器”的网页。在这些网页中，我们展示了国际空间站(ISS)、Seasat、TRMM、UARS、USERS、AJISAI等许多亮丽的人造卫星的飞行课程和时间。这些网页已经在许多小学、初中或高中的科学课堂上使用。在这些卫星中，国际空间站是最明亮的卫星，被认为是几乎所有的观测者。此外，几名宇航员在国际空间站执行许多任务的事实吸引了观察者。在观察到国际空间站在星夜中经过后，许多人想知道，如果他们是留在国际空间站的宇航员，怎么能看到地球。这项研究的主要目的是开发从国际空间站轨道上看到的地球三维模拟软件。为了做到这一点，我们使用了NASA网站上的国际空间站轨道要素计算出的国际空间站实时位置。地球的3D物体是由带有测高数据的卫星图像制作的。地球物体的3D展示已经使用Matrix-Engine进行了操作。开发的网页名为“3D地球观测导航器”。当前版本的3D地球观测导航器显示的是没有云的地球图像。对添加气象卫星实时云图进行了许多技术评估，另一方面，对人造卫星观测导航器进行了几项改进，其中包括对卫星星等的预测。

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.
