A new Version of the India’s Polar Satellite Launch Vehicle (PSLV) rocket on Monday carrying the Digital intelligence satellite, Emisat for the Defence Research Development Organisation (DRDO) and 28 other third party satellites lifted off by the next launch pad .
About 17 minutes into the flight, the rocket could eject the 436 kg Emisat into a 749 km orbit.
“There’s increased need for satellites out of strategic sectors. About six/seven satellites are intended to be built,” a senior official told IANS on the condition of anonymity.
After placing into orbit the Emisat, the rocket will be brought down to place into orbit the 28 overseas satellites at an altitude of 504 km.
This will be accompanied by bringing down the rocket farther to 485 kilometers when the fourth stage/engine will turn into a payload stage carrying three experimental payloads: (a) Automatic Identification System (AIS) out of ISRO for Maritime satellite applications shooting messages transmitted from boats (b) Automatic Packet Repeating System (APRS) from AMSAT (Radio Amateur Satellite Corporation), India – to help amateur radio operators in tracking and monitoring place data and (c) Advanced Retarding Potential Analyser for Ionospheric Studies (ARIS) from Indian Institute of Space Science and Technology (IIST) – to the structural and compositional studies of ionosphere, the space agency said.
The entire flight sequence will take about 180 minutes from the rocket’s lift at 9.27 a.m.
The 28 global customer satellites — 24 from the US, two from Lithuania and one each from Spain and Switzerland — will weigh approximately 220 kg.
“It’s is a particular mission for us. We’ll be using a PSLV rocket with four strap-on motors. Further, for the very first time we will be trying to orbit the enemy at three distinct altitudes,” Indian Space Research Organisation Chairman K. Sivan had told IANS.
In its usual configuration, the rocket will probably have six strap-on motors hugging it’s first stage.
But the 44.5 metre tall rocket that lifted off on Monday had four strap-on motors and its particular configuration is designated as PSLV-QL.
