No matter what China does, it will not be able to escape from this ‘Trinetra’ of India, GSAT-20 will become the sentinel from Andaman to Lakshadweep.

New Delhi: India’s advanced communication satellite GSAT-N2 i.e. GSAT-20 has been launched into space by Falcon-9 rocket of Elon Musk’s company SpaceX. The satellite has reached its designated place and started revolving. Indian Space Research Organization i.e. ISRO has now taken control of it. This mission was launched from Cape Canaveral, Florida. Let us know about the KA bands deployed in this mission, which makes this mission special. Former ISRO scientist Vinod Kumar understands the strategic aspects of this mission from Srivastava.

GSAT-N2 will not be able to kill even Parinda.

GSAT-N2 i.e. GSAT-20 is a KA bands satellite whose 32 user beams will monitor the entire Indian subcontinent including the Bay of Bengal, Andaman and Nicobar Islands in the Indian Ocean and Lakshadweep in the Arabian Sea. Due to this, even birds in the sea will not be able to kill. Of these, 8 narrow spot beams are dedicated to the North-East region, while 24 wide beams are dedicated to the rest of India. This satellite is built on carbon fiber reinforced polymer base. The presence of these bands means that the range of the signal is wider.

What is the primary objective of GSAT-20 satellite?

According to Vinod Kumar Srivastava, the entire capacity of the CMS-02 satellite was leased to Dish TV. GSAT-20 is the sequel to the GSAT series of communications satellites. The satellite aims to add data transmission capacity to the communication infrastructure required for India’s Smart Cities mission.

Will sense China’s move, will keep an eye on the sea

According to Vinod Kumar Srivastava, the strategic aspect of this satellite is that it will be able to monitor the activities of countries like China from the Arabian Sea to the Indian Ocean. Apart from communication, the army will also be able to take advantage of this. This will strengthen those radars which have KA bands.

What are KA bands, what is its frequency limit?

According to former ISRO scientist Vinod Kumar Srivastava, KA bands are a frequency range in the microwave part of the electromagnetic spectrum, which can be used for satellite communications and strategically. This band ranges from 27 to 40 GHz, with a wavelength of 1.1 to 0.75 cm. That means this will double the internet speed from the current speed.

KA bands are used in military aircraft and telescopes.

Vinod Kumar Srivastava explains that apart from satellite communication, KA bands can be used in military aircraft and space telescopes etc. It gives higher speed data compared to other bands. In this the spectrum rules are less stringent. It also allows the use of smaller antennas.

Where did KA bands come from and what did they originate from?

However, since the satellites are in KA bands, the signals may get degraded during rain and humidity, which may impact the quality of communication. The name KA Bands comes from the German word Kurz, meaning small. This is a sub category of K-band.

Will bring revolution in the world of satellite communication

According to Vinod Kumar Srivastava, KA bands satellites can provide high speed broadband internet connectivity, digital video and audio transmission. This will further increase the internet speed, making it easier to watch or download movies on OTT.

This band is perfect for interplanetary missions

According to Vinod Srivastava, KA bands are considered perfect for interplanetary missions. In fact, parabolic antennas can be more advantageous than similar dish antennas at high frequencies.

Better for law enforcement radar

KA bands are used in law enforcement radar. The radar frequencies this band uses are typically between 33.04 GHz and 36 GHz.

Ease of installation of KA bands

KA Bands equipment is small, allowing it to be quickly deployed and set up. It can be used to detect the speed of vehicles and in space telescopes.

That’s why Musk’s rocket was chosen

The satellite will be owned and operated by New Space India Limited (NSIL), the commercial arm of ISRO. ISRO chose SpaceX to launch GSAT-20 because India’s indigenous heavy rocket launch vehicle Mark-3 does not have the capacity to lift such a heavy satellite.
