All navigation satellites in place                                                     Will undergo several months of testing

(Xinhua special feature). On April 28 India launched a satellite, marking the completion of the set-up of this South Asian country’s own regional satellite navigation and positioning system.

India announced the successful launch of IRNSS-1G satellite using a homemade rocket at the Sriharikota launch pad in Andhra Pradesh.

IRNSS is the abbreviation for “India Regional Navigation Satellite System”. India launched the first satellite of this system on April 28, 2013. This latest launch was the seventh and the final satellite of the system with the estimated life of the satellite estimated to be 12 years.

According to the Hindustan Times, this system will be tested for three to four months after which it will start running. According to the estimates by ISRO, this system will take at least a year to be put into operation for business application. India hopes that this satellite navigation and positioning system will allow India to break away from dependence on America’s Global Positioning System (GPS).

The design of the Indian GPS consists of seven satellites in orbit and two other spare satellites on the ground. They will provide land, sea and sky positioning and navigation services with a radius of 1500 kilometers. It covers India and peripheral parts of the region with positioning accuracy of 10 meters. It provides two types of services, one is for all the users and other for authorized users.

Hindustan Times report also said that apart from civilian use, the development of India’s own satellite navigation and positioning system will also be extremely important for safeguarding accurate positions during wars.

India also hopes that this system will help in developing related domestic industries. The incumbent head of the satellite navigation project in ISRO, A.S Ghanshyam, said that once the system is put into operation, companies may make large quantities of terminal equipment for signal reception.

He also suggested that Indian government should make it compulsory for government organizations and departments for emergency affairs to use this system, in order to produce excitement in businesses to take the initiative for researching and developing terminal equipment, thus in turn, expanding the scope of the application of this system further.

导航卫星全部就位,将接受数月测试

“印度版GPS”组建完成

新华社特稿 印度28日发射一颗卫星,标志着这个南亚国家组建完成自己的区域卫星导航定位系统。
印度当天在南部安德拉邦的斯里赫里戈达岛发射场用国产火箭发射一枚IRNSS—1G型卫星并宣布发射成功。
IRNSS是“印度区域导航卫星系统”的缩写。印度2013年发射这一系统的首颗卫星,28日发射的是第7颗、也是最后一颗,预计使用寿命为12年。
《印度斯坦时报》报道,这套系统将接受3至4个月测试,然后开始运行。印度空间研究组织预计,这套系统至少需要一年才能投入商业应用。印度希望这套卫星导航定位系统能使印度在本国范围内摆脱对美国全球卫星定位系统(GPS)的依赖。
按照设计,印度版GPS系统由7颗在轨卫星组成,另有两颗卫星在地面备用。它们将提供陆地、天空和海洋定位和导航服务,覆盖半径为1500公里,涵盖印度及周边部分地区,定位精度为10米。它将提供两种服务,即向所有用户开放和面向授权用户。
《印度斯坦时报》说,发展印度自己的卫星导航定位系统,除了民用,对战时保障精确定位也至关重要。
印度还希望这套系统能带动国内相关产业发展。印度空间研究组织卫星导航项目前主管A·S·甘尼香说,一旦投入商业应用,企业会大批生产接收信号的终端设备。
他建议,印度政府应该强制要求政府机构和紧急情况部门使用这套系统,以激发商家研发终端设备和软件的积极性,从而有助于进一步扩大这套系统的商业应用范围。
