Agni V Missile test launch

[Vishwarupa]

Agni V missile test likely on Wednesday

Range preparation for the maiden test of India's indigenously developed nuclear capable 'Agni V' ballistic missile with a strike range of over 5,000 km is "near complete" and the trial is likely to be held from Wheeler Island off Odisha coast this Wednesday.

"If everything goes as per schedule, the trial is likely to be taken up on Wednesday from the launch pad-4 of the Integrated Test Range (ITR)," a senior ITR scientist said.

The three stage solid fuelled missile would be put into test for the first time with some advance and indigenous technology with the support of a canisterised mobile launcher, said the scientist, adding that "networking and health parameters of both main and sub-systems have been validated during pre-test check-up".

"For tracking and monitoring the pre-determined trajectory of the missile, sophisticated radars as well as telemetry stations positioned in different locations have been linked up," the scientist said.

As it is a development trial, due attention has been given to the health parameters of this long range missile and some critical technologies have been incorporated, another scientist said, adding that there are two new composite motors to propel the missile to distances bordering ICBM capabilities.

All data about performance are to be thoroughly analysed and assessment has to be made for its next trial accordingly, he said.

If the trial is successful, it will club India into a select band of countries in the world to possess the technology for Inter-Continental Ballistic Missiles (ICBM).

The surface-to-surface missile Agni V which can carry a pay-load of 1 tonne is 17 m long, 2 m wide and weighs 50 tonnes.
Scientists associated with Agni V project are quite optimistic about its performances, as the first trial of Agni IV on November 15 last year was highly satisfactory in terms of its 'control and guidance' system.

The 5000 km range Agni V missile would add another feather to such class of missiles that India possesses at present. The Agni I has 700 km, Agni II (2,000 km), Agni III and IV (3,000 plus km) range.

i think A4 would easily go to 5500 km and A5 would cross 8000 km, but let them get first succesful test flight. BTW that pic says all is ready.

Well analysed!

Thank you, sir.

First, the Chandrayaan probe was not crash landed, it was guided landing to a particular point to release the debris for analysis by the orbiting payloads.
Moon Impact Probe

Next India already has demonstrated re entry technology, when it landed a capsule in Bay of Bengal

Third, ICBM's don't use external guidence, they use RLG's, INS, MINGS, all have been tested in Agni 4 and other variants too.

Yes, agree with Moon Impact Probe point. It was a bit inaccurate of me to say Chandrayan probe just crash landed. It indeed was an impactor. Interestingly, Indian scientists are extremely resourceful. We weren't yet ready to land a probe, so what they did was make it an impactor. The impact would raise lunar debris and the orbiting probes would analyse the temperature variance to detect heat signatures of water. Marvellous. Ingenious.
Please provide some sources for your second claim. Furthermore, space capsule re-entry and missile re-entry are very different things. Would be grateful if you shed some light on their points of similarity.
And finally, about ICBMs. Agreed they do RLG, INS, STAR navigation, but GPS course corrections are also a part of the subsystems. In short, the more data a missile can have about its present position, the more accurate it is.

Also to collect data about how to do controlled landing for future missions.

Here it is, from our beloved neighbor: Xinhua - English
Re-entry is the same in broader sense, all in all a missile/space craft leaves the atmosphere and an RV enters in to the atmosphere, it needs shielding from the atmosphere so that it doesn't destroys itself mid air.

And finally, about ICBMs. Agreed they do RLG, INS, STAR navigation, but GPS course corrections are also a part of the subsystems. In short, the more data a missile can have about its present position, the more accurate it is.

NO it does not have it: http://www.thehindu.com/news/national/article2630898.ece

The DRDO did not use any satellite during Agni-IV's flight.

But check the multiple way of taking guidance available internally.

All in all, I don't think GPS/GLONASS are not used for guidance, correct me if I am wrong here

[utubekhiladi]

they say that AGNI 5 can strike farthest part of north china with in 18-25 minutes. missile travels at speed of MACH 24. this missile will worry the dragon for sure

 

[utubekhiladi]

possible picture of AGNI 5. can any one confirm

 

[Yusuf]

possible picture of AGNI 5. can any one confirm

A5 is a canister launched missile. I doubt this is A5. Nobody will get a shot of it till D day.

 

[sayareakd]

if you want to compare both A3 and A5



Uploaded with ImageShack.us

both looks same except for welding part in A3.

First of all, if MINGS stands for micro navigation then the report is laughable. Check out what Micro navigation actually is The Future of GPS: Micro-Navigation | BrickHouse Security Blog
Now please check out this link to validate if ICBMs do indeed use Global positioning for redundancy (BTW even if the definition of MINGS is accepted, then also it is a type of satellite navigation)
Intercontinental Ballistic Missiles
The guidance and control package that a country needs to support an ICBM depends upon the desired accuracy it expects to achieve with its missile. Without a PBV, this accuracy is going to be poor, and more rudimentary technology can be used. Any industrial/advanced nation manufactures equipment and parts that, when properly constructed, can be used to build an inertial measuring unit. In addition to the United States, a proliferant can turn to Belgium, Germany, France, Holland, Sweden, Norway, Finland, Austria, the Czech Republic, Hungary, Russia, Italy, China, North Korea, South Korea, Taiwan, Australia, New Zealand, Egypt, or India. In general, though, a guidance and control unit, using a digital guidance computer and consistent with a staged missile, cannot be built from cannibalized parts of older, analog guidance systems. A PBV requires a small liquid rocket motor, cold gas thrusters, or many small total impulse solid rocket motors. These motors must be supported by a small guidance, control, and navigation unit that flies with the RVs until they are dropped. GPS units have wide application for this particular phase of the ICBM trajectory. Because of existing export controls, a proliferant would have to modify an over-the-counter GPS receiver to operate at high altitude and at ICBM velocities. The knowledge of how to build a GPS receiver is now widespread, however, and many individual hobbyists have built receivers that evade these restrictions. A modified GPS receiver or a GLONASS receiver is completely consistent with the needs of a PBV.

Ofcourse, an ICBM relies mainly on its internal guidance specially on INS and STAR tracking systems(Stellar guidance), but GPS is provided nonetheless for redundancy. NB: RLG is a type of INS.

About the re-entry vehicle, yes, possibly it has been done. Else we could not have thought of an a5 test. You are correct, in all probability.

The missiles doesn't take continuous guidance, that is the meaning of not using satellite communication, as we don't have any global system, our missiles are made to work in case those systems are denied to us.

About the re-entry vehicle, yes, possibly it has been done. Else we could not have thought of an a5 test. You are correct, in all probability.

So you agree that we posses the Re entry technology?

spikey, the difference is mentioned here

Business Line : Industry & Economy / Economy : Agni V, all set to be test-fired

The stage is set for the maiden test flight of Agni V, India's long range missile, with capability to reach 5,000 km.

Powered by the flying success of Agni-IV (over 3,500 km range) in 2011, Indian missile scientists will face their toughest test, as the home-grown missile, will have to reach inter-continental distances, soar great heights and survive very high temperatures, as it re-enters the earth's atmosphere and seeks to destroy its target.

Agni V, will cover approximately 1/8th of the Earth's circumference (which is 40,000 km). It will be a three-stage, all solid fuel powered, 17-metre tall, with capability to carry nuclear payload, said Mr Avinash Chander, Chief Controller (Missiles & Strategic Systems), DRDO.

The Wheeler island, off the coast of Orissa, is bustling with preparations, that have reached the final stages.

The Defence Research and Development Organisation (DRDO), is targeting to launch its most ambitious, strategic, nuclear deterrent missile during the window of April 18-20.

"Elaborate preparations have been completed. The technological capability that we will achieve will be a game changer for Indian defence. The strategic options it provides are immense. The technological challenges we are trying to overcome are many. Only the US, Russia, France and China have the capability," Mr Chander told Business Line, before going to the Wheeler Island for the big test.

The DRDO has proven most of the technological capability in Agni-IV. It has to be extended to higher temperatures in Agni-V. For example, the re-entry temperature for Agni-IV was from a high of 3,000 degree C to 50 degree C.

In the case of Agni-V it will be 5,000 degree C to a climb down of 50 degrees. This is very, very challenging in many ways, he said.

Unlike re-entry space vehicles, missiles re-enter at a much steeper angle of descent and in very few seconds. They face severe thermal effect. Both technology and material is needed to overcome this hurdle. Agni-V has its two upper stages completely built with composites (corrosion free and can withstand high temperatures).

Agni-V will see the test of several technologies and composites. It will see for the first time flying a large sized, composite rocket motor. It will have a very compact payload. New technologies to recover data will be deployed. An array of tracking stations, two ships in the high seas has been deployed, defence scientists explained.

"Very compact payload", is this referring towards, some new design of war head?

they are indirectly saying the missile won't carry 1 ton payload as advertised

 

[nitesh]

they are indirectly saying the missile won't carry 1 ton payload as advertised

They mentioned 1.5 tons

 

[plugwater]

I don't know from where you got that, stop imagining things. Jeez!!

It will carry more than one ton!!

So you agree that we posses the Re entry technology?

if anyone dont agree he should see this

this is civilian example.

Post 862 is a good one. I would like to draw your attention to the following

He has to his credit the distinction of developing and demonstrating the capability of an indigenous ring laser gyro-based INS+GPS system comparable with such systems developed by few selected countries in the world. He played a pivotal role in building India's totally indigenous multi-satellite constellation receiver (GPS+GLONASS+GAGAN) for high-dynamic applications. He has also developed India's first miniaturised, 500 fibre-optic gyro-based INS+GPS (FINGS) system. Currently, he is working on MEMS-based miniaturised INS+GPS+GLONASS+Magnetometer System (MINGS) and indigenous navigation systems for Indian naval ships and submarines.

I agree that I wasn't aware of M standing for miniature and not micro, so we are good there. You are correct. But look at the highlighted part. Read the above carefully once more. It clearly says that MINGS consists of both GPS and Glonass. We do agree that they are satellite navigation systems aren't they? Therefore I hope you conclude that missiles do employ GPS course corrections after all. Ofcourse, the emphasis is on the word corrections. It does not take the GPS coordinates continuously but only intermittently to correct its course.

As far as RV is concerned. Personally I cannot conclude that success of space RV is same as Re-entry of warheads from the articles cited. But hey, I am no rocket scientist. Maybe they are the same thing. So I do hope you are correct and we indeed possess re-entry tech.
