New Communication Satellites Of ISRO To Lead In High-Speed Internet Epoch

ISRO (Indian Space Research Organization) is aiming to guide in an epoch of high-speed connectivity of Internet in the nation with the roll out of heavy-duty satellites for communication. Giving information related to the forthcoming roll outs in 2018, Dr K Sivan, the chairman of ISRO, claimed to the media in an interview: “We will roll out Gsat-11 in May or sooner in April.” The satellite having a weight of 5,725 kg will transport 40 transponders in the Ka-band and Ku-band frequencies. It is capable of offering connectivity with high bandwidth with almost 14 Gbps (gigabit per second) speed for data transfer.”

“We will roll out Gsat-11 from the spaceport of Europe as it is a satellite worth 5 Tons. Around the similar period in May, ISRO will roll out Gsat-29 from Sriharikota via our GSLV Mk III rocket. After that, we aim to roll out Gsat-20 itself from India by 2019,” the ISRO chief claimed to the media. On June 5, 2017, the space agency of India had rolled out Gsat-19, which also carried Ka-band and Ku-band transponders with high throughput communication.

Dr Sivan claimed, “Jointly, all these satellites will offer high connectivity for bandwidth of almost 100 Gbps. They will offer high-speed connectivity of Internet in rural regions as well and assist bridge the digital gap.”

The satellites are extraordinary since they employ various spot beams (a special type of transponder that works on a high frequency) that will elevate the connectivity and speed of Internet. A spot beam is a signal from satellite that is particularly aimed in power so that it wraps only a restricted geographical region on the planet. More power is generated if the beam is narrower. These satellites will use “beams” (signals) again and again various times so as to cover the complete nation. On the other hand, traditional satellite employs a broad sole beam (not aimed) to wrap wide areas.

Gsat-19 rolled out in 2017 employs 16 beams and is capable of transferring information at the sped of 13 Gbps. GSAT-20 will employ 40 beams. Every beam will have 2 polarizations, which will efficiently convert them to 80 beams. This device will have speed of 60–70 Gbps for data transfer.

ISRO’s decision to roll out these satellites for communication is coming at a time when Space X (the Elon Musk-established US space firm) is also engaged on making the biggest satellite-supported network of Internet in the globe.
