DRDO and PSU's

ISRO probably may have not been able to find where's the fault yet. Otherwise they wouldn't be keeping quite . Who knows?

Exactly. Its like train accidents. We kept on blaming trains, technicians boards. But later we came to know in many of them it was sabotage. In space its even more difficult to ascertain cause of failure. A strong EW shot or even laser/bullet shot can cause sudden malfunction in sattelite. The sat owner country may be totaly in blind what caused failure. If one component is always failing repeatedly - one of the remote possibility could it be EW. Because EW frequency they might be using might be affecting one particular component more strongly than others. Its all speculation but interesting what if. Anyway space is weaponized by US China and once by USSR. India will anyways have to spend more seriously on Aerospace wing anyway.

Atomc clock works on resonance of laser cooled atoms.... Cant be hurt with EW

Come to think about it all sattelites have some form of shielding to protect themselves of space radiation. IRNSS atomic clock has sufficient shielding for protection anyways. Shields do tell Electronics used in clock do need some shielding anyways.

How come no one has posted about everything that were revealed in the new Bharat Shakti series?

Astra mk2 being launched from a Su-30MKI using an indigenous launcher modelled on Russian AKU-58-1.

We got the very first glimpse of Astra mk2 in the IAF video released to commemorate the birth anniversary of airforce in 2022.
 
A certain PSU quoted a price of Rs 290 crores for integration of software defined radio SDR on Su-30MKI. SDI did it for free.

31 different systems which includes both sensors,avionics, weapon systems, pods have been integrated with Su-30MKI since 2010 by SDI.

At present 16-18 different DRDO designed weapon systems are being mated with Sukhoi.
 
What allows us to integrate any Western,Israeli OEM and indigenous weapons , pods with our Sukhois is because one of the two mission computers in MKI is Indian. The other is from a Russian OEM. Besides, SDI has also managed to get the source codes for N011M Bars. So weapon integration has become easier. The display processors are also ours.

SDI was responsible for the electronic mating of Astra with the MC and N011M Bars. It took SDI almost three years to develope and validate the codes which allows Astra to talk to Bars and MC on MKI.

Now this is the best scoop so far.

In one of the Astra bvr missile test firings, a LCA detected and tracked the target, then passed this track through SDR datalink to another LCA which then launched the missile without ever using its onboard radar.

This sort of cooperative target engagement capability has been masterd by very few nations around the globe. It allows the missile carrying ac to remain silent from RF emissions point of view and hence this ac won't be picked up by hostile ac rwr and esm.

This type of engagement capability is possible for any aircraft equipped with SDR and currently, Tejas mk1A, Su-30MKI, MiG-29 UPG, Jaguar Darin 2 and 3, Rafale either have SDR or is being equipped with it .

US Navy calls this capability National Integrated Fire Control- Counter Air. Therein, they use their E-2D to track hostile acs and pass the requisite data to Super Hornets and F-35C.

I think the firing aircraft have to use the radar in the engagement time because missile data link not linked like SDR data link which can enroll in the network as it own, up to certain degree missile can use it's data link for course correction and autonmous firing not totally independent and fully cold launch, also astra like missile have the range issue like 100 km if missile fired a target found by LCA around 90 km and firing su30 as missile truck flying way back around (20 - 30 km behind) it have to be launched in Launch envelope of astra bvr( to assure maximum Probablity of kill), other wise missile will became dud because it's battery runs oout before reaching its target, anyway this capabilities will help when Astra mk2 and mk3 integration completed,
 
Ku band MF-TDMA terminal: A Man Portable Ku band MF-TDMA terminal with 0.76M antenna has been realized. The antenna is a Parabolic Reflector Antenna with a positioning system made of lightweight Carbon Fibre-reinforced plastic (CFRP) material having 6 panels which are detachable. The Antenna pointing is done manually using IMU sensors, GNSS and a compass. The antenna has a Tripod mechanical assembly to position the Antenna and RF Front end. The RF front end consisting of BUC and LNBC of the terminal is compact and lightweight. The terminal baseband hardware is based on software-defined radio architecture. The baseband modem technology is based on Multi-Frequency- Time Division Multiple Access (MF-TDMA) in TX (Return link) and DVB S2 in Rx (Forward link). MPST derives power from the external power supply of 48V DC. The external power supply is powered by an AC/DC adaptor and battery. It is a robust terminal for Military Applications. It is capable of providing all-terrain secure high data rate IP services like VOIP, Video Streaming, Video Conferencing, File Transfer etc.

Military Combat Parachute System (MCPS)

ADRDE has undertaken the project titled Design & Development of Military Combat Parachute System (MCPS).

The MCPS system can be used in following modes:

  • High Altitude High Opening (HAHO): Jump from as high as 30,000 ft
  • High Altitude Medium Opening (HAMO): Jump from as high as 30,000 ft and opening anywhere up to 10,000 ft
  • High Altitude Low Opening (HALO): Jump from as high as 30,000 ft and opening anywhere between 9,000 ft – 5,000 ft.
