Mains Paper 3: Science & Technology | Awareness in the fields of IT, Space
From UPSC perspective, the following things are important:
Prelims level: Particulars of the GSAT-11
Mains level: Utilities of the GSAT -11 to high speed Internet services in India
- As most of India slept, its heaviest and most advanced communication satellite, GSAT-11, was shot to space from a European spaceport in faraway South America.
- GSAT-11 was launched from the Guiana Space Centre at Kourou in French Guiana.
About GSAT -11
- GSAT-11 is the heaviest ever built by ISRO.
- Its next biggest is the GSAT-17, weighing 3,477 kg and which was also launched for ISRO in June 2017 by the same European launch operator Arianespace.
- GSAT-11 is part of ISRO’s new family of high-throughput communication satellite (HTS) fleet that will drive the country’s Internet broadband from space to untouched areas.
- The broadband domain is now ruled by underground fibre and covers partial and convenient locations.
- Already up in space are two HTSs — GSAT-29 (November 14) and GSAT-19 (June 2017) — while one more is due to join them in the near future.
- They are all to provide high-speed Internet data services at the rate of 100 Gbps (Gigabits per second) to Indian users.
- ISRO has earlier said this speed would be far better than what is available in the country now.
- The HTSs will also be the backbone of pan-India digital or easy Internet-based programmes and services — such as Digital India, BharathNet for rural e-governance, and commercial and public sector VSAT Net service providers.
- According to ISRO, GSAT-11’s multiple spot beam coverage — 32 in Ku band and eight in Ka bands — will deliver an improved service of 16 gbps over the Indian region and nearby islands.
Arianespace and India
- Arianespace will launch two more GSATs, 31 & 30, which would be orbited from Guiana. GSAT-31 would go up first in early 2019.
- Since 1981 Arianespace has put to space 22 Indian communication satellites (including GSAT-11) and will launch GSAT-31 and GSAT-30 in 2019.
- It also holds the highest number of 590 commercial satellite launches to date worldwide.
