CHENNAI: Indian Space Research Organisation's Polar Satellite Launch Vehicle will launch six Singapore satellites from Sriharikota tomorrow.

The six satellites riding piggyback on PSLV-C29, to be launched from the first launch pad, from Satish Dhawan Space Centre in the spaceport of Sriharikota is scheduled for lift off at 6:00 pm tomorrow.

The 59-hour-countdown for the of PSLV-C29/TeLEOS-1 Mission began at 7:00 am yesterday and was progressing normally, ISRO said.


"Yes countdown is progressing normally," an official told news agency PTI.

The Mission Readiness Review committee and Launch Authorisation Board have cleared the countdown.

ISRO said the filling of propellant in PS4 stage (fourth stage) were completed yesterday.

ISRO would launch the six satellites into a 550 km circular orbit inclined at 15 degrees to the equator. It is using its trusted workhorse PSLV which is on its 32nd flight in 'core-alone' configuration without the use of solid strap-on motors.

Of the six satellites, TeLEOS-1 is the primary satellite weighing 400 kgs whereas the other five satellites include two micro-satellites and three nano-satellites.

TeLEOS-1 is the first Singapore commercial earth observation satellite.It would be launched into a low Earth orbit for "remote sensing" applications.

Antrix Corporation Ltd, the commercial arm of ISRO, has provided launch services in PSLV for 51 customer satellites from 20 countries so far.

The range of PSLV-C 29 is almost 19000 KM+ . It is about 2000 KM left of Ecuador

Good Luck ISRO.

 

[sharma1111]

Good Luck ISRO.

The range of PSLV is 3 times more than Agni V at height of 700+ KM without coming down

There are 6 satellites, so its space based MIRV ; Trans-stage Post Boost Control System (PBCS)

I'm pretty sure those pictures (in the OP) are not of ISRO's new flight control centre. The new control centre was opened relatively recently and is more impressive than even this^

None of Indian ballistic missiles apart from Agni V can launch satellites in any orbit.

Agni V is the only missile which can reach 7+ KM/second for small payload size

So Centripretal speed of satellite/launch vehicle for low earth orbit(radii 160km +) is the highest.

In case of PSLV C-29, all 6 satellites are released around Indonesia at speed of +7 km/second.
For next 30-40 minutes SLV switches off the engine and reaches in deep pacific near Ecuador with same speed at height of 500+ km.

After 40 minutes time, fourth engine is again switched on. The aim of this experiment is to test launch of multiple satellites in different orbit with same vehicle.


ISRO to test multiple burn fuel stage/engine on December 16

Chennai: The Indian space agency on Wednesday will be testing its ability to restart the fourth-stage engine of its rocket Polar Satellite Launch Vehicle (PSLV) on shutting it down after putting into orbit six Singaporean satellites.




Technically speaking, India will be testing its multiple burn fuel stage/rocket engine for the first time.

"The restart and shut off of the fourth stage engine is done as a first step towards launching multiple satellites but in different orbits," a senior official of Indian Space Research Organisation (ISRO), speaking on the condition of anonymity, told IANS.

Launching of multiple satellites with a single rocket is nothing new for ISRO and it has been doing that for several years. The challenge is however to launch several satellites at different orbits with one rocket and this is what ISRO will be testing out after PSLV ejects out six Singaporean satellites on Wednesday.

The PSLV rocket is a four stage/engine rocket powered by solid and liquid fuel alternatively.

"Restarting a rocket engine soon after it is shut off is a critical technology that has to be mastered. Once a rocket engine is activated, then the heat generated is very high. The trick is to cool it down in the space and to restart it at a short gap," an industry expert told IANS.

"This is entirely different from switching on and off the communication satellite's engines in the space. The interval between two restarts of a communication satellite engine will be in days. But in the case of restarting a rocket engine, the time gap will be in hours," the expert added.

"By that time the rocket's engine has to be cooled down. This part of the experiment is very critical," he explained.

On Wednesday, ISRO's PSLV rocket will blast off from the first launch pad at Sriharikota in Andhra Pradesh, around 80 km from here, with the six Singaporean satellites. All the satellites will be put into orbit around 21 minutes into the flight at an altitude of 550 km.

After that the rocket's fourth stage will be shut down.

"It will be coasting after that," an ISRO official told IANS.

Around 46 minutes after the launch of the sixth satellite, the fourth stage will be restarted when it is in a lower altitude of 523.9 km.

The engine will be in operational for four seconds and would go up to an altitude of 524 km before the stage is cut-off.

Meanwhile ISRO officials told the countdown for the December 16 evening launch of PSLV rocket is progressing smoothly.

On December 16, ISRO will be flying the 'core alone' variant of the PSLV rocket. The rocket will not have the strap on boosters, its standard feature

The successful launch of the six Singaporean satellites will take ISRO's total flights of foreign satellites to 57.

Out of the six satellites, the 400 kg earth observation satellite called TeLEOS-1 is the main passenger for the PSLV rocket and hence the mission is called TeLEOS mission by ISRO.

TeLEOS-1 is Singapore's first commercial earth observation satellite designed and developed by ST Electronics.

The other five co-passenger satellites are VELOX-C1 (123 kg), VELOX-II (13 kg), Kent Ridge-1 (78 kg), Galassia (3.4 kg) and Athenoxat-1.

The December 16 mission will be the last rocket launch mission for ISRO in 2015.

So far in 2015, ISRO has launched 14 satellites (three Indian and 11 foreign) from its rocket port in Sriharikota. Thirteen satellites were launched with PSLV rocket and one communication satellite - GSAT-6-with geosynchronous satellite launch vehicle (GSLV).

Last month India also launched its communication satellite GSAT-15 using the Ariane rocket of the European space agency which takes the total number of satellite launches in 2015 to 21 (17 foreign, four Indian).
