Isro in 2nd attempt to launch backup navigation satellite

印度空间研究组织第二次尝试发射备用导航卫星

CHENNAI: As the Indian Space Research Organisation (Isro) is making a second attempt to launch one of the backup satellites to replace NavIC navigation satellite constellation’s IRNSS-1A, whose three rubidium clocks failed, the space agency is taking efforts to install its signal receivers on the ground. Navigation satellite signal receivers which will give positioning and weather alerts to fishermen in deep sea were tested and more such devices will be fitted in boats in Tamil Nadu and Kerala.

金奈：印度空间研究组织正在第二次尝试发射一颗备用卫星来取代导航卫星星座的IRNSS-1A（该卫星的三颗铷时钟出现故障），宇航局正在地面安装信号接收器。将为深海渔民提供定位和天气警报的导航卫星信号接收器已通过测试，泰米尔纳德邦和喀拉拉邦的船只上将安装更多接收器。

On April 12, PSLV in 43rd flight will lift off with the 1.4tonne IRNSS-1I from the first launch pad in Satish Dhawan Space Centre, Sriharikota. Once placed in orbit, it will replace IRNSS-1A and join the constellation of seven satellites. The launch will be Isro’s second attempt at sending a replacement satellite. The previous mission in August 2017 where a PSLV carried IRNSS-1H failed after the heat shield covering the satellite failed to separate.

4月12日，PSLV将搭载1.4吨的IRNSS-1I进行第43次飞行，从位于斯里赫里科塔的萨蒂斯德哈万太空中心的第一个发射台起飞。进入轨道后，它将取代IRNSS-1A并加入7个卫星群。这次发射将是印度太空研究组织第二次尝试发射替代卫星。上一次发射是在2017年8月，搭载的IRNSS-1H极轨卫星运载火箭由于卫星的隔热罩无法分离导致发射任务失败。

Isro chairman Sivan said the receiver will be connected to the mobile phones of fishermen through Bluetooth. They will receive text messages on their position at sea, weather alerts and potential fishing zones. Fishermen need to download an application on their phones to decode and display the text messages. “We have demonstrated the usefulness of the receiver along with messaging services. Now, when fishermen go to sea, they are completely cut off from the shore for days. They don’t get any vital information like cyclone alerts. We have planned it in such a way, that they receive messages,” he said.

印度太空研究组织主席思旺说，接收器将通过蓝牙与渔民的手机相连。他们可以接收到海上定位、天气警报和潜在渔场的信息。渔民需要在手机上下载一个应用程序来解码和显示短信。“我们已经展示了接收器和信息服务的有用性。渔民出海时，他们与海岸就要完全失联好几天。他们没有办法获得像飓风警报那样的重要信息。我们通过卫星来解决这个问题，现在他们可以收到信息了。”

Isro officials said while the trials were conducted in Kerala, about 500 more fishermen in Kerala and 200 in Tamil Nadu will get the receivers.

印度太空研究组织主席的官员说，虽然是在喀拉拉邦进行试验，但在喀拉拉邦和泰米尔纳德邦，分别还有大约500多名和200名渔民将获得接收器。

The satellites’ receiver comes with three components- a chipset, a microcontroller and a Bluetooth module. The receiver, developed by Isro’s Space Applications Centre, Ahmedabad, is also being improved to save power in both mobile and the device.

卫星接收器有三个组件：一个芯片组，一个微控制器和一个蓝牙模块。由印度太空研究组织的空间应用中心艾哈迈德巴德开发的接收器也正在改进，以帮助移动设备和接收器节约电量。

Isro chairman said, “We are working with mobile phone manufacturers to see if they can incorporate the receiver as a component during manufacturing. Right now, these receivers are available as a separate unit and it can be used in many other applications including as a navigation device in vehicles.”

印度太空研究组织主席的主席说：“我们正在与手机制造商合作，看看他们能否在制造过程中将接收器内置到手机内。现在，这些接收器可以作为一个单独的单元使用，它可以被用于其他许多应用，比如用于车辆的导航。”

" Great Going....one failure should not put us on back foot ever....Wish ISRO a huge success"

干得好，一次失败不能打倒我们，祝印度太空研究组织获得巨大成功
