Answer by Anand Ranganathan:

Our ASAT missile spotted that satellite and DESTROYED it. Successfully.

Noob question - Was it the missile which did the spotting (tracking) or ground based sensors or a combination of both ?

Not an expert but will try and explain as i see it. Please appreciate the loop time from sensor detection to relative speed difference and distance to be covered and working out corrective thruster venting will be in nanoseconds! No missile borne radar & infrared sensors that will have a range beyond 80 to 100 km that also in narrow cone angle of +/- 30 degrees in front. The thing is you have to think of your KKV as a mini satellite that is being sent up to 300KM orbit by space rocket! The timing of launch and first and second stage performance will bring, the till then inert KKV, to within few kilometres to target satellite. I assume it will be lot easier if we think of it as a head on shot in a sense that missile has a velocity of about 3 km/sec ( with ~3 min rocket burn time) with relative speed difference between KKV and target satellite of 10 km/sec . Please note that target is moving at 7.7km/second and missile can only achieve max 3km/second velocity. The second stage will impart up to 3 km /second speed to KKV and bring it up to 300 KM and once there the KKV will fire its own thruster, once its close enough and make needed vectoring to ram into the target satellite.
Edited to correct interception mode.

@swamy39 Subramaniam Swamy is saying that we shot down satellite which was being used by Pakistan for its air-defence. That's the reason why friendly fire downed JF-17 bundars.

Mind boggling the amazing performance & precision required of the sub systems. I now wonder about the anti-ASAT tech which will need to be built into satellites. Perhaps with autonomous early detection and evasion systems.

It’s declared today... which may not mean that it actually happened today. Can anyone look into NOTAM issued indicating this test?

We are yet to see any country cry out debris created in orbit.

Where is natsec jeff and all the other open source analysts who are funded by the PRC to do the work that was once the NPA ayatollahs; calling.
By doing this whilst Xi is touring the EU trying to drum up legitimacy for the OBOR/BRI project, this mission makes it clear that the PRC navy will have its satellite connectivity over the IOR disrupted, and with it the overarching C3I archietecture that is required for the prc to make the BRI a reality.

No NOTAM needs to be issued for a test like this. Might have been necessary if we used the IAF's services to carry out the test, like the Americans did. I think the PLA in Sindh is now sh#^ting bricks at the thought that they may be completely blind to any hostilities & comms. CPEC just slid further into the abyss.

No such Anti-ASAT possible! imagine the trust required to move a 1000Kg satellite that is already going at 7.7 Km per second speed its like 1 tonne body going at Mach 22. You can slow it down or speed it up only marginally using thrusters we are talking about few tens of meters per second variations here over 20 to 30 seconds. That is called orbital corrections and are done at periodic interval till availability of gas in thruster tanks. Please note it takes total only 3 min from start to finish for ASAT! No one can have that short a decision to execution cycle for ground based operation and no satellite can have autonomous manoeuvring based on self detection of threat!

Great post by Patni.
Let me add the remaining missing links.
You will have long range radars, which detect and classify the target. Plus in the future (depending on resources), space borne sensors as well, which feed data back to the ground. The radar information & other sensor data goes to the ground control center, which analyzes the data and parses it based on additional signal processing, data processing for key identification variables. Once the target is selected, it assignes the relevant battery based on availability and suitability. The battery in turn receives the target information, the interception calculations and runs its own parallel algorithms to fine tune them for its interceptors. Then it launches the interceptor, which is datalinked to & receives corrective information from the ground based radars via special datalinks in the missile and with the battery. It monitors its own progress via its onboard navigation suite which will be a combination of inertial navigation and satellite fixes. When it reaches the right height, the 2nd stage is launched, which by itself is the KKV or the KKV sits on the 2nd stage. The KKV then scans for the target, acquires it and goes for it, using its onboard seeker to home for the specific/vulnerable spot programmed into its brain, and the course corrections are done by divert thrusters placed around the KKV. And all this happens in 3 minutes, with as Patni said, a precision of +/- 0.5 microseconds.

Anti ASAT is possible only for top secret kufr satellites like Riceeater-1 which will wear a lungi in space. Whenever chini ASAT comes near, it will remove the lungi and put it over the ASAT blinding it and will do lungidance in space, now wearing only a striped patta-patti underwear.

Why is the foreign ministry putting out FAQs?

Shouldn't this be Defence Ministry (security) putting it out ? Or PMO ? (The Department of Space is under PM's office)

Is the foreign ministry involvement part of a bigger diplomatic push/outreach ? Is it a pointer that any foreign pushback envisaged ?

Normally in sensitive cases, the diplomatic outreach happens before the event(unless by doing so, it acts as a trigger to counteract, or to trigger a counter-push to pressure and prevent the event)

Given the lack of warning about the prime minister's speech before; I would assume that pre-outreach wasn't a big thing.

Perspectives ? Are we over-thinking it ?

India is still treating this issue as a terrorist thing, different from a military issue.

Hence the MEA.

It doesn't make sense to.

While Pakistan has launched remote sensing satellites on Chinese rockets, the justification for satellites tends to be a far cry from the local terror sensing information or terror push.

And it badly undercuts the MEA own message about the test if it was meant to be a message to Pakistan...

As a military thing., it might make more sense than a terror thing.

It is to International audience that GoI is sending information thats why on MEA site! Indians are informed by PM himself and will have follow up briefing by relevant department of GoI. As is most all our DDM are puppets who take its cue from their sugar daddys in being Anti-Indian, so why not answer through MEA!

Agni to Mission Shakti, a long-desired capability tested.

Data Points to be noted:

Avinash Chander, former DRDO chief who was instrumental in building the organisation’s missile capabilities said: “This is an extension of the DRDO’s long-range ballistic missile programme of the extra-atmospheric interception. While we had been working on this technology for long, the current programme was initiated some time recently.” (Modi gave the go ahead in 2014)

Scientists with DRDO said the project had not got the final sanction under the previous UPA government

"The work on A-SAT missile had not begun under UPA government. Our scientists had the desire and the capability to develop anti-satellite missile since long, but they were not given clearance from the erstwhile Indian government, Jaitley said. All the work under this project has been done after 2014 after PM Modi gave permission, he further added."

Just note the willful damage done to India's Strategic interests by Congress.

Klaus · Post by **Klaus** » 27 Mar 2019 18:04

Just wondering aloud if the IN will be involved in any future ASAT ops as it opens up a whole range of possibilities to counteract PRC's C3I & space infra over the open ocean. Any of the new DDG's or upcoming SSBN's can accommodate BMD's in their silos? I see the next step as a user-trial which has to be one of the three services.

Ofcourse preparation must have been going on since months, possible reason of ASAT test timing in election time given by Baba:

After #BalakotStrike Chinese satellites were tracking our military bases. Specially 2 were focusing on us only. All information shared with Pakistan. So we had to postpone our operations.A strong message is given to China by #MissionShakti
We ll not tolerate ds type of adventure.

It is unlikely be a 'tail chase' mode. Reaching 7km/sec in 3 minutes is doubtful.

A person of his stature can comment on whatever he likes, saar.. provided he has put some time in to learn some things related it.. I would not pick up fight with him on legal matters, he is an expert there..

but..

Tremendous achievement by Namo Govt. It has thrown Pakistan electronic guidance of their jet fighter into blindness. Even Pak airforce jets flying over Pak territory can be shot down by blinded Pak radars. Congratulation to Namo’s l

Aren't we in BRF complaining loudly that we have Journos with absolutely no technical knowledge commenting on hi-tech defence projects.. why is this any different?

Anyway, my last on this.. don't want to derail a thread celebrating an excellent achievement..

Not sure if Baba's Chinese Sat reasoning is true or not, but I shudder thinking of the response from UPA would have been if they were made cognizant of such activities. I bet Armed forces & DRDO would be begging for go ahead to test ASAT missile but GoI (UPA) would be reinforcing the shackles on their wrists further while printing out more & more dossiers. Finally, a Govt which can take tough decisions necessary to address national security concerns & send the required message to concerned parties.

Space is the common heritage of mankind and every nation has the responsibility to avoid actions which can lead to the militarization of this arena," Pakistan's foreign ministry said in a statement.

"We hope that countries which have in the past strongly condemned demonstration of similar capabilities by others will be prepared to work towards developing international instruments to prevent military threats relating to outer space," it said, without mentioning India by name. "Boasting of such capabilities is reminiscent of Don Quixote's tilting against windmills," it said, in a reference to the delusional hero of the 17th-century Spanish novel by Miguel de Cervantes.

if its 3 stage weapon, then it will have a lot more slant range and ceiling than 300km task today. maybe to MEO orbits ... just saying...lot of juicy targets inhabit MEO orbits ... if we knock out the MEO tier of the navigation constellation of any system, I think the higher GSO tiers no longer really work they might be relays of some sort
