INDIA LAUNCHES ‘HEAVIEST’ SATELLITE FOR INTERNET ACCESS:GSAT-11
The Indian Space Research Organisation (Isro) launched the satellite-weighing about 5,854kg , the GSAT-11– is India’s heaviest “most-advanced” multi-band communication satellite from the Kourou spaceport in French Guiana.To be placed in a geostationary orbit, the satellite will play a vital role in providing broadband services across the country.
It is a next generation “high throughput” communication satellite configured around ISRO’s I-6K Bus, and has a designed lifetime of more than 15 years.
It will provide high data rate connectivity to users of Indian mainland and islands through 32 user beams in Ku-band and 8 hub beams in Ka-band.
The large high-throughput satellite (HTS), along with two smaller HTS satellites GSAT-19 and GSAT-29 launched earlier (by ISRO from Srihsrihkota) is the third in a series of four satellites aimed at achieving the government’s ambitious target to provide high data connectivity of 100Gbps in the country under the Digital India Mission.
GSAT-11 would provide high data connectivity to users across India, broadband connectivity to gram panchayats under the BharathNet project and support high data rate applications for enterprise network and consumer broadband applications.
Enabling in-flight Internet and village web services are the government’s other goals. By enabling rural high-speed connectivity the HTS satellite also promises to bridge the urban-rural digital divide.
LEARNING WITH TIMES
ISRO: It was established with it’s headquarter at Bangalore in 1969. It functions under overall control of department of space. K. Sivan; the current Chairman of Space Commission, Secretary, Department of Space, Government of India.
A geosynchronous orbit is an orbit around the Earth, where the object orbits once per day. A common kind of geosynchronous orbit is called a geostationary orbit, where the object orbits above the same part of the Earth at all times. Geostationary satellites are launched into orbit in the same direction the Earth is spinning. When the satellite is in orbit at a specific altitude, it will exactly match the rotation of the Earth. The Earth actually takes 23 hours, 56 minutes, and 4.09 seconds to make one full revolution. So this would put the satellite at approximately 35,790 km above the Earth.
This is an extremely useful type of orbit and is used for anything where a satellite needs to send or receive signals from the same part of the Earth all the time. It’s used for cell phone satellites, television satellites, weather satellites, as well as some military satellites.
