Prelims and Mains focus: About the proposed IDRSS: its aim and significance
News: India plans to ring in its own era of spacetospace tracking and communication of its space assets this year by putting up a new satellite series called the Indian Data Relay Satellite System (IDRSS).
Objective of IDRSS
How is it going to be implemented?
Why is IRDSS significant?
During the launch of the human mission and also when the crew craft orbits earth from a distance of 400 km, at least one ground station must see and track it. But with available ground stations, that would not be the case. Without data relay satellites, ISRO would have to create a large number ground stations everywhere or hire them globally and yet the crewed spacecraft would not be visible all the time.
Is India the first country to employ relay satellites?
No. Older space majors such as the U.S. and Russia started their relay satellite systems in the late 1970s80s and a few already have around 10 satellites each. They have used them to monitor their respective space stations Mir and the International Space Station, and trips that dock with them, as well as the Hubble Space Telescope.
