About 17 minutes into the flight, the rocket could eject the 436 kg Emisat into a 749 km orbit.
“There is increased demand for satellites from strategic businesses. About six/seven satellites are intended to be constructed,” a senior official told IANS about the condition of anonymity.
After putting into orbit the Emisat, the rocket is going to be brought down to put to orbit the 28 overseas satellites at an altitude of 504 km.
This will be followed by bringing down the rocket further to 485 km once 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 software capturing messages sent from ships (b) Automatic Packet Repeating System (APRS) from AMSAT (Radio Amateur Satellite Corporation), India – to assist amateur radio operators in monitoring and monitoring place data and (c) Advanced Retarding Potential Analyser for Ionospheric Research (ARIS) from Indian Institute of Space Science and Technology (IIST) – to the structural and compositional studies of ionosphere, the space agency said.
The whole flight sequence will take about 180 minutes from the rocket’s lift off at 9.27 a.m.
The 28 international customer satellites — 24 by the US, two from Lithuania and one each from Spain and Switzerland — will weigh approximately 220 pound.
“It is a particular assignment for us. We will be using a PSLV rocket with four strap-on motors. Further, for the very first time we’ll be trying to orbit the rocket at three distinct altitudes,” Indian Space Research Organisation Chairman K. Sivan had earlier told IANS.
The PSLV is a four-stage engine expendable rocket with switching solid and liquid gas. 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 on Monday had four strap-on motors along with its configuration is designated as PSLV-QL.
