NATIONAL & KARNATAKA: Chandrayaan-3: How indigenous amplifier played a crucial role in communication

In the case of space missions, amplifiers are instrumental in getting the message from the Lander and Rover to the satellite orbiting on the Moon’s surface, which is about four lakh km from Earth.

Chandrayaan-3 – India’s ambitious Moon Mission is a team work with several scientists, technicians, and entrepreneurs among others joining hands to make it a success.

Associate Director, Indian Space Research Organisation (ISRO) headquarters, Dr BHM Darukesha and his team had developed the 5-watt signal amplifier (for communication) which is an important part of Chandrayaan-3’s Lander and Rover when no other country came forward to provide it to India since amplifiers are mostly used by the military for defence operations. Darukehsa hails from Kottur in Vijayanagara district.

In the case of space missions, amplifiers are instrumental in getting the message from the Lander and Rover to the satellite orbiting on the surface of the Moon, which is about four lakh km from the Earth. ISRO was looking for a 5-watt signal amplifier for its Moon missions.

According to informed sources, a Japanese firm had agreed to provide its own 12-watt amplifier. “However, it was not suitable for use in space travel and Isro had to develop its own amplifier. This responsibility was assigned to Darukesha, who headed the Integrated Circuit (IC) design team.

The 5-watt amplifier developed by him and his team has won various awards by ISRO. These amplifiers were fitted in the Lander and Rover of Chandrayaan-1 & 2, Mangalyaan and now Chandrayaan 3,”
added sources.

“An amplifier is required to know the operational status of a satellite or spacecraft that is launched from the Earth. It was an opportunity and privilege for me and my team to develop it at a time when other countries had backed out,” Daurkesha told this newspaper.

Born on August 6, 1974, to Suvarnamma and Mahadevaiah – a government primary school teacher in Shivpura Gollarahatti in Kudligi taluk. Darukesha was appointed as a scientist in ISRO in 1998.

CTTC scientists’ hard work pays off

A team of 150 scientists, engineers and technicians, who toiled hard for the last two years to mould different types of components used in the lander, erupted in joy when lander module Vikram landed on the dark side of the Moon’s surface. It was the lander that had crashed during the Chandrayaan-2 mission in 2019. CTTC delivered over 75,000 components for Chandrayaan-3.

NATIONAL & KARNATAKA: AIRBORNE TECHNOLOGIES: IISc Develops Autopilot System for Drones

The reason for India’s slow progress in this sector is due to the non-availability of essential indigenous electronics components like microcontrollers and sensors at a reasonable cost.

With the exponential rise in drone usage across sectors like industrial applications, agriculture, logistics and defence, the need for indigenous avionics systems has become crucial. In order to reduce dependence on foreign drone technology, the Indian Institute of Science (IISC) has made a significant achievement in the field of unmanned aerial systems.

The Artificial Intelligence and Robotics Laboratory (AIRL) at IISC announced that the team has successfully developed an indigenous industrial-grade autopilot system for drones. The team said this achievement is the initial step towards the indigenization of avionics systems for drones in India. This feat was possible through the utilization of Indian-made Vega Microcontrollers, developed by the Centre for Development of Advanced Computing (CDAC), as part of the Digital India RISC-V Program (DIR-V).

The indigenously developed technology will help reduce the reliance on microcontrollers in future drone avionics projects. Professor Suresh Sundaram, Associate Professor at the Department of Aerospace Engineering, who headed the project said, “Our autopilot system, powered by Vega Microcontrollers, showcases the immense potential of homegrown solutions in the unmanned aerial systems domain. We are confident that this breakthrough will pave the way for further advancements in this field and contribute to the growth of the drone ecosystem in India.”

India’s most used drone technologies which include an unmanned aerial system (UAV) that can help run a basic operation system and forward data to a navigation control unit, are imported from China, US, Israel, and several European countries.

The reason for India’s slow progress in this sector is due to the non-availability of essential indigenous electronics components like microcontrollers and sensors at a reasonable cost. The country also lacks a skilled workforce working on the UAV systems. Using imported tech comes with major security concerns such as hacking and data manipulation.

The country has been on a steady growth towards chip manufacturing and CDAC is a ray of hope in developing world-class microcontrollers. “This move will cut millions of dollars worth of electronics import over the years and make India self-reliant in terms of UAV technology,” said the laboratory.

NATIONAL & KARNATAKA: AMAZING CONSTRUCTION FEAT: India’s First 3D-Printed Post Office Built in just 43 days, Opens in Bengaluru

The structure cost Rs 26 lakh to erect, which is 40% less than the conventional construction process.

India’s first post office building using 3D printing technology was declared open by Communications and Railway Minister Ashwini Vaishnaw on Friday at Cambridge Layout in the city.

Built in just 43 days, the structure cost Rs 26 lakh to erect, which is 40% less than the conventional construction process.

The built-up area of the post office is 1021 square feet with Larsen & Tourbo Limited constructing it under the technological guidance of IIT Madras.

Speaking after launching it virtually from the General Post Office, Vaishnaw lauded the giant strides India has taken in new technology like the 4G, 5G and the Vande Bharat Express making full use of indigenous talent. “The noise level inside the Vande Bharat is 100 times less than that inside an aeroplane. While the Shinkansen (Japanese bullet train) takes 54 seconds to achieve an acceleration of 100 kmph, the Vande Bharat does it in 52 seconds,” he said.

Chief Postmaster General S Rajendra Kumar billed the new technology as cost-effective and environment-friendly. Explaining the 3D construction process, he said there are two types involved. “One construction process involves printing of building elements at a manufacturing facility and assembling at site. The other process is to do the building construction on-site, as per the input design. The new PO building falls under the latter category,” he said.

Operations Head of L & T, South and East, George Abraham said the total digital workflow eliminates human error. “The construction cost involved is just 40% of the conventional construction method. Since it is a fully automated process, it assures excellent product quality and is sustainable,” he said.

Elaborating on the construction technology, a release said, “A robotic printer deposits the concrete layer by layer as per the approved design. Special grade concrete which hardens quickly is used to ensure bonding between the layers for printing the structure.”

Later, fielding queries from newspersons, Vaishnaw assured that the Centre was committed to the implementation of the Bengaluru Suburban Railway Project as soon as possible. On the Vande Bharat Express not touching the promised speed limit in Karnataka, the minister said that it would happen when the railway tracks are upgraded.

Asked if next year’s election process was delaying the framing of rules for the personal data protection law introduced recently, the Information Technology Minister replied in the negative.

Bengaluru Central MP P C Mohan, Postmaster General, Bengaluru Region, L K Dash, and Dean of Industrial Consultancy and Sponsored Research, IIT Madras, Manu Santhanam were present.

Minister’s visit to post office marred by protest

The Communications Minister’s visit to the new post office post-launch was marred by protests from supporters of Shanti Nagar MLA N A Haris who alleged that the local MLA was shown disrespect by not being invited to the function and not having his name printed on the invitation. They were dressed in black, blocked a portion of the road and raised slogans in support of Haris.

A top postal official, however, said, “Postal officials had gone in person to invite him on Thursday. His grouse was that he had been invited late for the function. He told us yesterday itself that a protest would be organised by his supporters. Moreover, only the minister’s name was printed on the invite. The name of the MP or top officials was not printed.”

The protest forced Vaishnaw to leave the venue immediately. “Many BJP workers were waiting with bouquets to meet the minister and have a brief chat with him. We are really disappointed with the behaviour of the Congress workers,” said a local BJP leader.

KARNATAKA /NATIONAL & INTERNATIONAL: COTO: Woman-only Social Media App. – A Safe Space for Women created by Bengaluru’s Aparna Acharekar, Co-Founder

This Independence Day, the co-founder of a women-only social media app, speaks about preserving freedom of expression for women, preventing online hate and maintaining the app’s identity.

Scrolling through social media these days, one cannot miss instances of hate – from homophobia to casteism, threats to slander, it comes in all forms. But women face an overwhelming share of that hate.

This Independence Day, the co-founder of a women-only social media app, speaks about preserving freedom of expression for women, preventing online hate and maintaining the app’s identity to ensure it doesn’t share the fate that befell Twitter.

In an attempt to curb this problem and to provide a safe space for women on the internet, Aparna Acharekar co-founded the women-only social app Coto (short for come together).

“The idea came from women facing harassment. We noticed that the more a woman expressed her thoughts online, the more hate she got. This was especially true for women influencers and celebrities. Not just here in India. We have data that shows this pattern across the world. We wanted to create a space where women would be able to ask questions and express themselves without inhibitions,” shares Acharekar, who has over two decades of experience in content creation.

The internet provides people with the luxury of anonymity. But some take advantage of this luxury to masquerade themselves in many ways. So, how does Coto ensure no one abuses the app? “We have various ways of verifying users. We use reliable and effective social recognition systems to ensure someone isn’t falsifying their identity. We also used two-factor authentication and if someone wishes to, they can opt to enter their Aadhaar details (other government ID data for people in other countries). We have taken ample steps to ensure that only women and transwomen get access to our app,” she explains.

coto has been live since January 2023 and surprisingly the app hasn’t recorded any instance of hate or abuse, largely due to its content moderation practices.

“First, there is an AI-level moderation, which picks derogatory works or inappropriate words. Inappropriate words or context, in our case, are very different from what you find on other social media. On a women-only app, when somebody uses the word breast or vagina, those words are not flagged off as inappropriate. Secondly, communities moderate their content and their members. So community members can report to, and escalate to admins of every community, pretty much like on a WhatsApp group. So if there is anything that is not contextual to the community or may be harmful to the community, the creators themselves moderate it. The platform does not unless their complaint has escalated,” she says.

coto comes with an identity – to create a space for women online. So, what are their plans to ensure the identity remains intact and doesn’t eventually lose itself, something that has plagued other social media apps over the years? “We believe social media should be decentralised. Women who come to coto and set up their communities are given coto tokens/gains. It essentially means that a large part of the platform will be owned by the community creators and members.” Regarding plans of expanding, Acharekar elaborates, “Presently our largest user base is in India and Egypt. But the application is available globally. We are soon planning on launching in Indonesia.”
