科學院遙感與數字地球研究所宣布,中國將在北極新建遙感衛星數據接收站,計畫今年開工、兩年建成。
人民日報報導,中科院遙感地球所所長郭華東說,北極站是中國第四個、也是在境外第一個陸地遙感衛星數據接收站,衛星站位於瑞典,覆蓋北極、歐洲,北極站建成後,可以從外部對比研究中國的環境狀況和資源分布。
中國現有陸地遙感衛星數據接收站位於北京密雲、新疆喀什、海南三亞,「在中國境內呈三足鼎立之勢」,可接收面積覆蓋中國陸海全部領土和亞洲70%區域,已獲取地球表面大量觀測數據。
中國的遙感衛星一直被美國認為是有「軍事用途」目的。但人民網刊登時評反駁,瑞典允許中國在其境內建立「北極衛星接收站」,就證明中國「陸地遙感衛星數據接收站」的和平目的。「因為瑞典是中立國,如果中國將用於軍事目的的設施建在他們的國土上這可能嗎?」
評論並抨擊,美國一直指責他國的衛星是用於軍事用途,其實,恰恰是美國在經常進行一些秘密發射。2013年8月28日,美國用美國最大的「德爾塔IV」型重型火箭將一顆機密間諜衛星送入太空。「之前有外國媒體透露,在全世界總計400多顆在軌運行的軍用或疑似軍用衛星中,明確屬於美國的就有200多顆,占總數的一半還多。」
評論砲轟美國霸道,「只要是中國做什麼美國都會出來說三道四。其實,美國在指責別人的時候,他們自己卻在幹這類事情」。
衛星遙感是各國空間對地觀測的主要手段之一。過去中國科技工作者只能通過購買國外衛星數據獲取資料。評論指出,經過多年建設,中國遙感衛星地面數據接收站,是世界上接收與處理衛星數量最多的機構之一,接收並保存了自1986年以來的各種衛星數據資料達310萬筆,是中國最大的對地觀測衛星數據檔案庫。
China Set to Operate First Overseas Satellite Data Receiving Station in the
Arctic○Yibada (2015.03.17) http://en.yibada.com/articles/19953/20150317/china-first-overseas-satellite-data-receiving-station-arctic.htm#ixzz3UiJw6RXb
China is set to begin operation of the first overseas
satellite data receiving station which will be established in Sweden.
The Chinese Academy of Sciences, Institute of Remote
Sensing and Digital Earth Institute said that the station will be China's fourth
of its kind and the first station to be built outside China. The other three are all located in China.
The government said that the data receiving station
will start its operation in the next two years and will gather information covering Europe and the Arctic region.
According to experts, the station will allow China
to receive data gathered remotely by satellite that the country can use for its
research on environmental conditions, global climate change and distribution of resources.
"By using observation information from outside
China, we can compare this data with the resource and
environment data that is gathered within the country. In this way, we can monitor changes in China's
environment. This could help China to take
targeted measures to prevent disasters and conduct relevant research and evaluations,"
the professor was quoted as saying.
At present, China has three satellite data receiving
stations for domestic use which are located in Xinjiang, Beijing and Hainan Province.
The three stations provide satellite data
on the country's total land and water territory, including 70 percent of all Asian
territory.
The data obtained by satellite on the Earth's surface
often show observations that can be used in many fields of research, especially
on disaster, resources,
environment, agriculture,
ecology, and biodiversity,
among others.
