Didnt find any info of this ? Only ff of gaganyaan announced by ISRO
You didn't just find that in this particular article. IDRSS are available in annual report. And without them, Gaganyaan is impossible.

Without IDRSS, Gaganyaan won't be there since communication blackout isn't supposed to be there in multi-day long missions. Even if India's manned mission is delayed for it.

Novel technique for tracking solar eruptions that disrupt space weather to be used in India’s first solar mission


Scientists have developed a new technique to track the huge bubbles of gas threaded with magnetic field lines that are ejected from the Sun, disrupting space weather and causing geomagnetic storms, satellite failures, and power outages.


As the ejections from the Sun, technically called Coronal Mass Ejections (CMEs), cause various disturbances of the space environment, forecasting their arrival time is very important. However, forecasting accuracy is hindered by limited CME observations in interplanetary space.


Software named Computer Aided CME Tracking Software (CACTus) based on a computer vision algorithm was so far used to detect and characterise such eruptions automatically in the outer corona where these eruptions cease to show accelerations and propagate with a nearly constant speed.


However, this algorithm could not be applied to the inner corona observations due to the vast acceleration experienced by these eruptions. This severely limited the capability to track the eruptions as CMEs accelerate in the lower corona. Moreover, with the advancement in space technology, there has been a tremendous increase in the amount of data obtained from spacecraft. To identify and track the solar eruptions in huge number of images can become tedious if done manually.


Research led by Mr. Ritesh Patel, Dr. Vaibhav Pant, and Prof. Dipankar Banerjee from Aryabhatta Research Institute of observational sciences (ARIES), Nainital, an autonomous institute under DST, Government of India, along with their collaborators from Royal Observatory of Belgium, have led to the development of an algorithm, CMEs Identification in Inner Solar Corona (CIISCO) to detect and track the accelerating solar eruption in the lower corona. CIISCO has been successfully tested on several eruptions observed by space observatories, including Solar Dynamics Observatory and Solar-Terrestrial Relations Observatory, PROBA2/SWAP launched by NASA and ESA, respectively. The research was published in the Solar Physics journal.

A parabolic profile could be observed, (c) Identified parabolic profile by CIISCO overplotted on (b) by dashed line.





The parameters determined by CIISCO are useful to characterise these eruption in the lower corona, a region where the properties of such eruptions are less known. An implementation of CIISCO on the large volume of data available from space observatories mentioned above will be helpful to improve our understanding of eruptions in the inner corona. As India’s first solar mission, Aditya-L1, will be observing this region of the solar corona, implementation of CIISCO on the Aditya-L1 data will provide new insight into the CME properties in this less explored region.

An industry body representing the likes of Amazon, Hughes, Google, Microsoft and Facebook has written to the Telecom Regulatory Authority of India and the Indian Space Research Organisation asking them to stop SpaceX from pre-selling the beta version of its Starlink satellite internet services in India.

Off-topic: I am working on making a video of ISRO, beyond the 2020s consisting of all the planned missions including the lunar polar exploration mission, gaganyaan, aditya, mangalyaan 2, shaukrayaan. Can anyone give a list of all the planned missions be they official ones or not yet official ones like the space station?

Bonus fact:
You can re-upload the same video in 2029-30 with updated title: ISRO Beyond 2030s.

And once they achieve what they are planning we all would be chest thumping .

Ofcourse we will. I will do it too!
You will get praise when you achieve heights.

I have already seen whats happening around the world now. Small independent teams (100-200 employees) with below $1 Billion in funding are launching rockets and planning to capture the rocket and re-use now. I don't have same kind of hope with ISRO as i had 5-8 years back.
