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

本研究的目的是为国际空间站的科学教育活动开发学习软件。我们开发了题为“人造卫星观测导航”的网页。在这些页面中，我们介绍了许多明亮的人造卫星的飞行路线和时间，如国际空间站（ISS）， SEASAT， TRMM， UARS， USERS， AJISAI等。这些网页已经在许多小学、初中、高中的科学课上使用。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认为它是可以发现的。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。许多人在观察了国际空间站在繁星点点的夜晚经过后，想知道如果他们是呆在国际空间站里的宇航员，怎么能看到地球。本研究的主要目的是开发从国际空间站轨道上看地球的三维仿真软件。为了做到这一点，我们使用了国际空间站的实时位置计算从国际空间站的轨道要素从美国宇航局网站。地球的三维物体是由卫星图像和测高数据制成的。地球物体的三维展示已经用矩阵引擎操作。开发的网页被命名为“地球三维观测导航员”。当前版本的地球3D观测导航显示的是没有云的地球图像。为增加气象卫星拍摄的实时云图，已经进行了许多技术评估。另一方面，对“人造卫星观测导航仪”进行了若干改进，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.
