Monday's Indian Space Research Organisation (ISRO) satellite launch was exceptional for several reasons. Perhaps most memorably, the space agency invited ordinary people to witness the launch live, from its command centre.

New Delhi (Sputnik): India's space agency ISRO has successfully launched the electronic intelligence satellite EMISAT from its Sriharikota space launch station in the southern part of the country. The payload was accompanied by 28 Nanosatellites, which India launched on behalf of foreign clients.

ISRO ex-chairman G Madhavan Nair: #PSLVC45 is a very imp milestone for ISRO. It's not only going to launch our own satellite but also those from other nations. Uniqueness of this mission is,it's going to place satellites in 3 different orbits.I hope it'll be 100% success as usual pic.twitter.com/4hguGJ5SS0 — ANI (@ANI) April 1, 2019

The low-earth orbit surveillance satellite, launched today for military purpose, weighs 436 kg and will monitor and provide the locations of enemy radar sites deep in their territory.

Until now, India had been dependent on using airplanes as early warning platforms, but today's satellite will give India a space-based platform to monitor its enemies.

India's second technological feat in space within a week: It launches a new PSLV rocket carrying 29 satellites, including EMISAT, an electronic signals intelligence (ELINT) satellite armed with Kautilya, an ELINT package.

"The immediate mission that we are targeting is the PSLV C-45. This mission is special in the sense that for the first time, the PSLV will have a three-orbit mission in a single flight," ISRO chairman K Sivan said.

The EMISAT is a satellite jointly developed by the ISRO and DRDO. It reportedly has a basic architecture similar to HySIS and is based on the Small Satellite Bus (SBS)-2 which was first used in the satellite Saral. The satellite has been under development since 2010.
