晨昏軌道 dawn-dusk orbit

　　China plans to send a meteorological weather satellite into a dawn-dusk orbit. The satellite was designed and built by the Shanghai Academy of Spaceflight Technology, affiliated with the China Aerospace Science and Technology Corporation. It will be the world's first polar-orbiting weather satellite in a dawn-dusk orbit.

　　A dawn-to-dusk orbit is a sun-synchronous orbit in which the satellite tracks but never moves into the Earth's shadow. As the sun's light is always on the satellite, it can always use its solar panels.

　　中國(guó)計(jì)劃將一顆氣象衛(wèi)星送入晨昏軌道。這顆衛(wèi)星由中國(guó)航天科技集團(tuán)所屬上海航天技術(shù)研究院設(shè)計(jì)建造，將成為世界首顆晨昏軌道極軌氣象衛(wèi)星。

　　晨昏軌道屬太陽(yáng)同步軌道，衛(wèi)星在這條軌道上運(yùn)行，絕不會(huì)進(jìn)入地球陰影(不會(huì)被地球遮擋)。由于始終有太陽(yáng)光照射，衛(wèi)星能夠一直使用太陽(yáng)能電池板工作。
