News Excerpt
Government of India had decided to develop an indigenous Data relay satellite system which would be allowed for space-to-space tracking and communication of its space assets

Pre-Connect
•    A relay satellite works similarly as racers in a relay race in order to transfer data between the ground and space.
•    Satellites in orbit cannot pass along their information to the ground stations on Earth if the satellite does not have a clear view of the ground station.
•    Relay Satellite serves as a way to pass along the satellite's information.
•    It can also send information from the ground to the satellite to tell the satellite what to do
•    Major Space powers such as the U.S. and Russia started their relay satellite systems in the late 1970s-80s and a few already have around 10 satellites each.

Analytica
IDRSS Overview:
    It will be a set of satellites that will track, send and receive information from other Indian Satellites.
    These weigh around 2000 kg and will be placed in geostationary orbits which are at a distance of 36000 km.
    A satellite in GEO covers a third of the earth below and three of them can provide total coverage.

Function:
    It will track and establish a continuous connection with Indian satellites especially those which are in the low-earth orbits which have limited coverage of earth.
    It will play a vital role in advanced LEO missions such as space docking, space station, as well as distant expeditions to moon, Mars and Venus.
    It will play a critical role in monitoring launches.

IRDSS and Gaganyaan
    The first beneficiary of IRDSS will be the crew members of the Gaganyaan mission of 2022. It will allow them to be fully and continuously in touch with mission control throughout their travel.
    The first IRDSS will be sent towards the end of 2020. It will precede the pre-Gaganyaan experimental unmanned space flight which will have a humanoid dummy.
    A second one will follow in 2021. The two will offer near-total tracking, sending and receiving of information from the crew 24/7.
    Without data relay satellites, ISRO would have to create a large number of ground stations everywhere or hire them globally and yet the crewed spacecraft would not be visible all the time.

GSAT-30
     Part of ISRO’s earlier INSAT/GSAT satellite series.
     Telecommunication Satellite configured on ISRO’s enhanced I-3K Bus structure.
     It will provide communication services from Geostationary orbit in C (Covering Gulf countriesand a large number of Asian countries and Australia.) and Ku bands (Indianmainland and islands).
     In-orbit operational life of GSAT-30 is more than 15 years.

Vyom-Mitra
    It is a half-humanoid which is also first “Women” astronaut of ISRO.
    It is powered by speech synthesis software and artificial intelligence.
    It will simulate the human functions required for space before real astronauts take off before August 2022.
    The half-humanoid will ride to space in the first test flight of the human space mission, Gaganyaan.

Bhuvan Panchayat V 3.0
    It forms the part of ISRO’s Space based information support for decentralized Planning Update Project. It is for better planning and monitoring of government project.
    The program began in 2011to empower Panchayati raj institutions. Theweb portal was launched for visualization, planning and monitoring of schemes at panchayat levels.
    Services it offered to Stake holders:
o    Database Visualization
o    Data Analytics
o    Generation of automatic reports
o    Model-based products and services
    ISRO will collaborate with stakeholders to understand their data requirements
    It will help in providing geo-spatial services to aid gram panchayat development planning process of the Ministry of Panchayati Raj.

East Asian Observatory
    India is in discussion with East Asian Observatories Consortium of eight countries to be part of their project of building large telescopes and pool resources.
    It is formed by East Asian Core Observatories Association in order to pursue joint projects in astronomy within the East Asian Region.
    It is chartered as a non-profit Hawaii Corporation
    Member states are- China, Japan, Taiwan, Korea as full members and Thailand, Vietnam, Malaysia and Indonesia as ‘observers.
    Participation of India will allow for the establishment of new kinds of telescopes which could aid the observation of new black holes and throw light on cosmic phenomena
