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.
Details:
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.
- 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.
More Details:
- 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.
One must know:
- 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.
