Must be, it's the standard issue BVR missile on Tejas as of now (although Israeli I-Derby ER is integrated as well).If tejas were to be exported, would Astra be available ?
Yes .. astra is made in india .. integration in tejas mk1 is near completion . It ll be used in tejas mk1a as well . Further dual pulse version of astra and sfdr ll be integrated later .If tejas were to be exported, would Astra be available ?
It will have to comply US export restriction.Yes .. astra is made in india .. integration in tejas mk1 is near completion . It ll be used in tejas mk1a as well . Further dual pulse version of astra and sfdr ll be integrated later .
On BRF it was said that soft deliveries are actually going on... they did not make it news because the Jets are still based in Bangalore and their going to update it as after its integrated to it.weseaaj kaafi dino baad aya hu yaha , wese i know delivery toh nahi hui hogi
I hope you must be talking about the below excerpt? Please let me know if otherwiseOn BRF it was said that soft deliveries are actually going on... they did not make it news because the Jets are still based in Bangalore and their going to update it as after its integrated to it.
Ultimately, deployment will be at Rajasthan & Srinagar for the 1st two squadrons.
The information you have provided is not known to many.It will have to comply US export restriction.
Astra uses field-programmable gate array (FPGA) designed and manufactured by US company Altera (now Intel), RF sampling ADCs are designed and manufactured by US company from Analog Devices while other RF interfacing Analog Front End (AFE) from Texas Instrumentation are being used.
FPGA is where all the digital filers, all logic, the brain of the Astra missile along with system control resides in.
RF sampling ADC along with some other analog front end are used to interface with the seeker.
Seeker is provided by AGAT for initial batches of Astra BVR. They also provided support for seeker interfacing.The information you have provided is not known to many.
I trust you have verified the content.
Many were under the impression that Russia was the chief source of technology for the initial Astra mk1 versions. Including the data link which is supposed to be the clone of the R77 BVR data link. Also the seeker was from AGAT of Russia for the initial batches of the missile.
Let me rephrase Washington is not helping. They are selling. Its in our interest to buy from US and its in their interest to sell us such components. By allowing others to use their product for critical sub-assembly/system they maintain their edge in the market also preventing others from establishing competing products. If tomorrow Russian come with competing FPGA no one will be interested in them. Even countries embargoed by US will try to get their hands on US products instead of going with Russians.I guess many people would be surprised to hear that Washington is allowing such technological help to India's missile programmes to take place.
AFAIK with Mk. 2 we are trying custom ASIC but nothing is concrete. As for FPGA their is no plan to indigenous such technology.What is the present status of our efforts to indigenise the imported technology.
Let me rephrase they are not cooperating. They are selling. Its a buyer seller relation.How extensive is the cooperation in high technology between India and the US.
For semiconductor will be our US is our go to guy as they are market leaders.Is the US now the primary source of high tech defense technology for our indigenously designed weapons.
TrueAnyway the fact is that we still have to do a lot of work in designing and developing indigenous technologies for attaining true self reliance.
Well, sourcing high technology components and systems from the US is OK as we are yet to develop indigenous alternatives.Seeker is provided by AGAT for initial batches of Astra BVR. They also provided support for seeker interfacing.
That being said all the control algorithm, interfacing with control surfaces, target identification and tracking, ECM and ECCM were developed by DRDO.
The FPGA is used to implement these control algorithms, interfacing logic with control surfaces via motors and actuator, target identification and tracking, ECM and ECCM along with other features like data link. This part was done by DRDO even though the seeker was from AGAT.
You need a processor (silicon) to execute algorithms for these individual sub-systems. Companies like Raytheon tend to design custom ASIC for this purpose (implementation of the above mentioned sub-systems) but this involves a lot of risk. So DRDO went ahead with FPGA route as it has lot flexibility mitigating the custom ASIC development risk and cost but has some disadvantages.
Why FPGA? Because it is practical, efficient (from project management point of view), easier, less risk and cheaper than designing your own ASIC.
Why American? Take a pick they are market leaders or the only providers of such system or convenience or economics or proven design and tooling and the list goes on.
QRSAM is currently 90% indigenous and will reach 99% incrementally guess which component will be imported.

True
Won't FPGA be kind of slow for a real time system like a missile ?Why FPGA? Because it is practical, efficient (from project management point of view), easier, less risk and cheaper than designing your own ASIC
FPGA's are very fast. When compared to CPU's FPGA's may fail when compared on cost... but not on speed.Won't FPGA be kind of slow for a real time system like a missile ?
Not really.Won't FPGA be kind of slow for a real time system like a missile ?
Ready in hangar ,flown too ,but IAF haven't taken them , reason unknown but photos and videos relay that they are ready , about 10Did HAL made any deliveries of FOC in 2020/2021?
SOURCE--i have heard that there is problem with the computer of tejas it is failing again and again, they will replace these computer with new one (which will be installed in tejas mk2)
this current computer is pretty old.
any news on that??
This is normal. The mission computer was designed ages ago. Most of its components would have become obsolete by now. These obsolete components will be replaced by newer compatible components. ICs tend to be obsolete by 15-20 years of their introduction. Most of the software should work out of the box.i have heard that there is problem with the computer of tejas it is failing again and again, they will replace these computer with new one (which will be installed in tejas mk2)

any news on that??
Just another lie by the united nations AF. This is just an upgrade as ADA/HAL Tejas mk1A is preparing to roll out Tejas mk1a. There was not a single incident as IDRW article suggests.i have heard that there is problem with the computer of tejas it is failing again and again, they will replace these computer with new one (which will be installed in tejas mk2)
this current computer is pretty old.
any news on that??
