ISRO To Provide Internet Through 4 Satellites By The End Of 2019

Tired of slow internet speed in India? Indian Space Research Organisation (Isro) has assured that by the end of 2019. The country will certainly get high-internet speed with the launch of four heavy-duty communication satellites.

Isro chairman K Sivan told TOI “The launch of four high throughput satellites will provide the country broadband connectivity of over 100 gigabits per second (Gbps) by next year.

Gsat-19 was already launched in June last year; Gsat-29 will be launched by November and Gsat-11 (Isro heaviest satellite weighing over 5.7 tonnes) will be launched from French Guiana by December. The launch of Gsat-20 has been scheduled next year.”

He added, “Together, all these satellites will provide high-speed internet connectivity in the country, especially in rural areas, and help bridge the digital divide.”

How does ISRO satellite internet work?

Instead of connecting your router to cable you will be connected to a dish which connects with a satellite above the earth. This satellite will be in contact with the ground station which is connected to the internet. If there is any request from your computer the small dish above your house will be asking the satellite for an answer. This satellite sends the answer to your dish which is uploaded by the ground station.

The actual range and speed of satellite internet is low and costly because only one satellite is used for the whole country. the satellite disperses the signal which decreases the internet speeds. ISRO is using beaming technology which beams the whole signal to smaller parts of India.

The new satellites are special as they use multiple spot beams (a special kind of transponder that operates on a high frequency) that will increase internet speed and connectivity.

A spot beam is a satellite signal that is especially concentrated in power so that it covers only a limited geographical area on the earth. The narrower the beam more is the power. These satellites will reuse “beams” (signals) several times in order to cover the entire country. In contrast, the traditional satellite uses a broad single beam (not concentrated) to cover wide regions.

With around 500 million internet users, India has the world’s second largest internet user base, ranked only behind China. But the country still ranks 109th in mobile internet speed and 76th in fixed broadband speed, according to Ookla’s last November Speedtest Global Index.

The country’s average mobile speed was 8.8Mbps and broadband speed was 18.82Mbps. On the other hand, Norway ranked first in the world for mobile internet, with an average download speed of 62Mbps as of November and Singapore led in the fixed broadband category, with a 153Mbps average download speed.
