NEW DELHI: Amid preparations for its high-profile Rs 800 crore Chandrayaan-2 mission scheduled for an October launch, Indian Space Research Organisation (Isro) is also gearing up to launch a slew of important satellites in the coming months.

新德里:印度空间研究组织(ISRO)计划在未来几个月内发射一系列重要卫星,为十月发射耗资80亿卢比的月船2号做好准备。

Some of these satellites are significant for strategic reasons as they will help the military keep an eye on our hostile neighbours and safeguard our land and sea borders.

其中一些卫星具有重要的战略意义,将帮助印度军方监视敌对邻国,保卫印度陆地和海上边界。

Isro will launch a dedicated satellite, Gsat-7A, for the Indian Air Force (IAF) in September and an advanced remote sensing satellite, Risat-2A, for surveillance purpose by the end of the year.

ISRO将于今年9月发射印度空军专用的卫星Gsat-7A,并于年底发射一颗先进的遥感卫星Risat-2A,用于监视目标。

Gsat-7A, which will be lifted by a GSLV Mk II rocket, will enable the IAF to interlink different ground radar stations, airbases and AWACS aircraft. It will also boost the IAF’s network-centric warfare capabilities and enhance its global operations.

Gsat-7A将由GSLV Mk II运载火箭发射,印度空军可以将地面雷达站、空军基地和预警机联网,提高印度空军的网络中心作战能力,并增强其全球作战能力。

The satellite will be similar to Gsat-7 or Rukmini, which was launched on September 29, 2013, exclusively for the Navy. Rukmini has helped the Navy monitor the Indian Ocean Region (IOR) as the satellite has a nearly 2,000 nautical mile ‘footprint’ and provides real-time inputs to Indian warships, submarines and maritime aircraft and also boosts the force’s networking capabilities on the high seas. Rukmini, considered the Navy’s ‘eye in the sky’, is also being used to keep tabs on Chinese warships in the Indian Ocean.

这颗卫星与2013年9月29日发射海军专用卫星Gsat-7(Rukmini)类似。Rukmini帮助印海军监控印度洋近2000海里的区域,并为印度军舰、潜艇和海上飞机提供数据实时输入,增强印海军在公海上的网络能力。Rukmini被誉为印海军的“天空之眼”,也被用于监视印度洋上的中国军舰。

Risat-2A, which will be launched by the end of this year by a PSLV rocket, is an advanced remote sensing satellite that will boost the country’s surveillance capabilities.

今年年底,Risat-2A将由PSLV运载火箭发射,Risat-2A是先进的遥感卫星,将提高印度的监测能力。

The satellite, which will carry a sophisticated synthetic aperture radar that operates at 5.35 GHz in C band, will help in earth observation irrespective of the light and weather conditions of the area.

这颗卫星携带一个复杂的合成孔径雷达,在C波段以5.35 GHz的频率运行,可以全天候观测地球,而不受地区的光线和天气状况的影响。

Risat-2A, which can be used for civilian purpose, will primarily be used for land mapping but will also be significant for analysis of the ocean surface. Risat-2A will be the third in the series of Risat satellites.

Risat-2A可用于民用目的,主要用于土地测绘,但对海洋表面的分析也具有重要意义。Risat- 2A将是第三个Risat系列卫星。

After the 26/11 terror attacks in Mumbai in 2008, Risat-2 satellite took priority over Risat-1 and was launched in April 2009 as the former carried an Israelbuilt X-band radar, which boosted surveillance capabilities of the security forces.

2008年11.26孟买恐怖袭击之后,印度于2009年4月优先发射Risat-2卫星,该卫星携带了以色列制造的x波段雷达,增强了安全部队的监视能力。

Cartosat-2 series satellite, launched on January 12, is also a remote sensing satellite and significant for the military too as its panchromatic camera can produce images less than 1 metre in resolution.

今年1月12日发射的Cartosat-2系列遥感卫星,对军方至关重要,因为它的全色片相机可拍摄空间分辨率小于1米的图像。

In fact, it is said that the Army used images from the earlier Cartosat satellite to plan the surgical strikes on Pakistan terror launchpads in September 2016.

事实上,军方曾计划在2016年9月使用Cartosat卫星的图像对巴基斯坦恐怖分子实施外科手术式袭击。

Besides the military satellites, Isro will also launch its “heaviest satellite ever” Gsat-11 weighing 5.7 tonnes from French Guiana by June.

除了军事卫星,ISRO还将在6月前发射“有史以来最重的卫星”Gsat-11,重达5.7吨。

The heavy-duty communication satellite is so massive that each solar panel is over four metres long, equivalent to the size of a room.

这个重型通信卫星的每个太阳能电池板都超过4米长,相当于一个房间的大小。
