Despite Gsat-6A jolt, Isro gears up for navigation sat launch on April 12

尽管Gsat-6A出现失误，印度空间研究组织全力备战4月12日的导航卫星发射

NEW DELHI: Despite snap of the communication link with its recently launched communication satellite Gsat-6A, Isro is gearing up for the scheduled launch of its next navigation satellite IRNSS-1I on April 12.

新德里：尽管与最近发射的通讯卫星Gsat-6A失联，印度空间研究组织依然全力备战预定于4月12日发射的下一颗导航卫星IRNSS-1I。

Isro chairman Dr K Sivan told TOI that the "upcoming launches like of IRNSS-1I will not be affected because of the snap of signal link with communication satellite Gsat-6A". While one team of Isro is busy with re-establishing the contact with Gsat-6A, the second team is busy in preparations for the launch of the navigation satellite, says a source in Isro.

印度空间研究组织主席金思旺博士告诉《印度时报》，“即将进行的IRNSS-1I发射任务不会受到Gsat-6A信号失联的影响”。印度空间研究组织的一名消息人士称，该组织的一个团队正忙于与Gsat-6A重新建立联系，第二支团队忙于准备发射导航卫星。

IRNSS-1I, which will be launched by PSLV-C41 rocket from Sriharikota on April 12, will replace faulty IRNSS-1A navigation satellite, whose three Rubidium atomic clocks (meant to measure precise location data) had stopped working two years ago. IRNSS-1I weighing 600kg (dry mass) and a life span of 10 years will become the eighth satellite to join the constellation of navigation satellites called NavIC (Navigation with Indian Constellation) or popularly known as IRNSS.

IRNSS-1I卫星将于4月12日在斯里赫里戈达岛航天发射中心由PSLV-C41火箭搭载发射，取代出现故障的IRNSS-1A导航卫星，这枚故障卫星的3个铷原子钟(用来测量精确位置数据)已于两年前停止工作。IRNSS- 1I重600公斤(干质量)，寿命为10年，将成为导航卫星星宿中第8颗新加入的卫星(印度导航星宿)或称为印度区域导航卫星系统。

The seven-satellite indigenous navigation system is a smaller version of the American GPS, which with 31 satellites has global reach. The 'desi' GPS is designed to provide accurate position information service to users in India as well as the region extending up to 1,500 km from its boundary.

7颗卫星的自主导航系统是美国GPS的缩小版，它在全球范围内拥有31颗卫星。“desi”GPS系统能为印度以及从印度边境方圆1500公里内用户提供精确的位置信息服务。

On August 31 last year, Isro tried to launch IRNSS-1H to replace faulty IRNSS-1A but the navigation satellite got stuck in the heat shield of the PSLV rocket during the launch. The satellite, still stuck in the heat shield and now declared space debris, is wandering in the near-earth orbit and will ultimately fall to the Earth.

去年8月31日，印度空间研究组织试图发射IRNSS-1H来替换出现故障的IRNSS-1A，但IRNSS-1H导航卫星在发射过程中被困在极轨卫星运载火箭的隔热层中。这颗卫星目前仍然困在隔热层中，已经被宣布为太空碎片，它目前正在近地轨道上漫游，最终将坠落回地球上。

On Gsat-6A, the space agency said efforts were on to resume communication with the satellite. Sources said there was no indication of any system malfunction or fluctuations during or after launch.

至于Gsat-6A，航天局表示正在努力恢复与卫星的通信联系。消息人士称，没有迹象显示在发射期间或之后出现过任何系统故障或波动。

So good to observe the confidant non-chalant manner ISRO is going about its future activities not missing a beat.Way to go ISRO.

能看到这种自信的态度非常好，印度空间研究组织应该勇于执行未来的发射任务。印度空间研究组织继续努力。
