The Indian Space Research Organisation (ISRO) has successfully launched an electronic intelligence satellite ‘Emisat’ for the Defence Research Development Organisation (DRDO) along with 28 third party satellites.
About the Launch
The notable aspects of the launch were a new variant of the Polar Satellite Launch Vehicle (PSLV); switching off and on the fourth stage engine couple of times; and the use of the fourth stage as an orbital platform carrying three experimental payloads.
PSLV first placed the 436 kg Emisat into a 749 km orbit. Then the rocket was brought down to put the 28 satellites into orbit, at an altitude of 504 km.
Then the rocket was brought down further to 485 km where the fourth stage/engine transformed into a payload platform carrying three experimental payloads:
- Automatic Identification System (AIS) from ISRO – for maritime satellite applications capturing messages transmitted from ships.
- Automatic Packet Repeating System (APRS) from AMSAT (Radio Amateur Satellite Corporation), India – to assist amateur radio operators in tracking and monitoring position data.
- Advanced Retarding Potential Analyser for Ionospheric Studies (ARIS) from Indian Institute of Space Science and Technology (IIST) – for the structural and compositional studies of the ionosphere.
For the first time, the launch also demonstrated new technology of putting payloads into three different orbits with a new variant of the Polar Satellite Launch Vehicle (PSLV) rocket.

The Human Space Flight Centre (HSFC) which would be the core of ISRO’s future manned missions was inaugurated at the ISRO headquarters in Bengaluru.
The Human Space Flight Centre will implement the first development flight of Gaganyaan with the support of existing ISRO Centres. The Human Space Flight Centre would be responsible for end-to-end mission planning, development of engineering systems for crew survival in space, crew selection and training and also pursue activities for sustained human space flight missions.
Gaganyaan which is India’s first manned space mission has been accorded highest priority by ISRO and the plan is to have the first unmanned mission in December 2020 and second for July 2021. The manned mission will happen in December 2021.
The Gaganyaan project is headed by R. Hutton, who was the Polar Satellite Launch Vehicle (PSLV) Director. The Gaganyaan project takes the Indian astronauts into space to a height of 350-400 km above the Earth and orbits around the planet for at least a week. The Indian astronauts would be conducting experiments in the space
