近日,我國(guó)首顆商用遙感衛(wèi)星成功發(fā)射。這顆備受矚目的“星星”都具備哪些功能?它的升空具有什么意義?在實(shí)現(xiàn)人們“飛天夢(mèng)”的同時(shí),它又能為我們的生活帶來(lái)怎樣的便利呢?
請(qǐng)看相關(guān)報(bào)道:
China launched "Jilin-1", the country's first commercial remote-sensing satellites, on Wednesday at noon, marking an important step in the development of remote-sensing space technology.
7日中午,我國(guó)成功將首個(gè)商業(yè)遙感衛(wèi)星“吉林一號(hào)”發(fā)射升空,標(biāo)志著我國(guó)在航天遙感技術(shù)方面邁出了重要一步。
“吉林一號(hào)”商業(yè)衛(wèi)星組星(a group of satellites for commercial remote-sensing services)包括1顆光學(xué)遙感衛(wèi)星(optical remote-sensing satellite)、2顆視頻衛(wèi)星(satellites for video imaging)和1顆技術(shù)驗(yàn)證衛(wèi)星(satellite for imaging technique testing),工作軌道均為高約650公里的太陽(yáng)同步軌道。
其中,“吉林一號(hào)”光學(xué)A星是我國(guó)首顆自主研發(fā)的(home-developed)高分辨率對(duì)地觀測(cè)光學(xué)成像衛(wèi)星,具備常規(guī)推掃、大角度側(cè)擺、同軌立體、多條帶拼接等多種成像模式(imaging modes),地面像元分辨率為全色0.72米、多光譜2.88米,可為國(guó)土資源監(jiān)測(cè)(land and resource monitoring)、土地測(cè)繪(land mapping)、礦產(chǎn)資源開(kāi)發(fā)、智慧城市建設(shè)、交通設(shè)施監(jiān)測(cè)、農(nóng)業(yè)估產(chǎn)、林業(yè)資源普查、生態(tài)環(huán)境監(jiān)測(cè)、防災(zāi)減災(zāi)(disaster prevention)、公共應(yīng)急衛(wèi)生等領(lǐng)域提供遙感數(shù)據(jù)支持。
All four satellites were developed and produced by Chang Guang Satellite Technology Co., Ltd. "Satellites are no longer far removed from people's lives," said Xuan Ming, board chairman of the company. "In the near future, more information provided by the satellites will be shared, and more satellite functions will be explored."
四顆衛(wèi)星組星均由長(zhǎng)光衛(wèi)星技術(shù)有限公司研發(fā)和生產(chǎn)。該公司董事長(zhǎng)宣明表示,衛(wèi)星離人們的生活不再遙遠(yuǎn),在不久的將來(lái),人們會(huì)分享更多衛(wèi)星提供的信息,并開(kāi)發(fā)出更多衛(wèi)星功能?!?/p>
