Once we considered isro as best performing asset of government , then came drdo of 2020.

Isro need reforms , launch should be frequent and project should be completed in time , they are deploying all their energy in gaganyaan , whereas we should focus more on reusable launch vehicle ,earn some profit and invest in rnd more
Exactly, what we are saying for ISRO today was what we were saying for DRDO a decade back.
ISRO used to be our darling in India, where none of Govt PSU were expected to perform. ISRO was doing amazing stuff although compared to these PSU only (global players were still much faster).
But over the last few years DRDO has managed to turned around its image completely, so many projects are running in parallel, so many projects are showing results also.
But ISRO seems to have lost track, even after so much years, where a lot of rocket stuff is outsourced to private players we are still seeing only 4-6 launches per year, SSLV nowhere to be seen, Powerful engines no where to be seen, only thing which is coming out is "ISRO is already working on the same".

Yeah DRDO really doing good work. ISRO need good and energetic chairman.

You never knew that DRDO had much more strain of work than ISRO.
DRDO had to literally do R&D even smaller components and defence programs required more knowledge because they're more advanced.
Humans are still noobs in space technology but progressing well in defence,getting new ideas and implementing it faster.
The reason could be more spending in defence.
Just imagine all other countries who are spending billions in defence spent that on space programmes a benchmark would've been set which would've caused same strain on ISRO.
Probably some people say "India has built cryogenic engine for GSLV,but couldn't make kaveri gas turbine"
Because turbofan engines are too hard and way more complex than cryogenic engines.
Defence technologies are more advanced than space technologies for now.

Why GOI not providing more funds to DRDO & ISRO why same figure every year.

30K crore to aise hi nikal ayenge . Isse jada to corruption main money loss hoon jatte hai.

Advantage of ISRO mainly around low costs for space mission and not in the case of launching satellites. India depends on forien countries for heavy launch and yet to start developement of super heavy rocket. USA/EU/Chinese need a large number of satellites for global space application, space exploration, planet exploration etc.
Question is does isro meeting Indian requirements- 88% yes which is a way better than DRDO/ HAL/ dpsu/ ofb.
NASA developing new space launch vehicle/crew module and buying engine from Russia and need Russia support. ISRO still one of the best.

ISRO main launch vehicle is PSLV.
PSLV gto - 1.3t,GSLV - 2.5t
Space x- Falcon 9 gto- 8t. Heavy - 28t.
Before making further comparison-
How many satellites does India, USA, Chinese, EU, Russia having and planned ?
How many satellites Indian private company having ?
ISRO meets Indian demands 85% which is a way better than DRDO/ofb/HAL/dpsu etc.
Only Chinese, French, Russian better than Indian because they having heavy lifter/super heavy lifter and operating space station.
I need a update in the case of USA, last time I read they're developing heavy/super heavy. Space x, etc were private, can't compare with ISRO. It's like comparing BSNL vs Jio.

GSLV MK3 is India’s heaviest payload carrying vehicle at 5 Tonnes...

DRDO just got excessive budget, support of private start ups for production and fruits of various projects that were running in parallel have shown results now. DRDO's tasks are far different and difficult from ISRO anyway.

As for ISRO, not much has been affected. Had coronavirus pandemic not been around and ISRO would have launched unmanned Gaganyaan, a couple more foreign satellites, tested landing module RLV and preparing Chandrayaan-3 this year, it would again have become bigger darling of people again. Lockdown pushed them at least 8-10 months behind if not an year.

SSLV is coming by end of this month after launch pad modification. And doubling launch frequency would take time because they will have to increase launch vehicle module production and modify pads and get budget for it. It tooks 10 years to go into 6-7 launches/year from 2-3 launches/year from previous decade. Going to 15+ would take a decade (not accounting SSLV launches and private companies as those are short cycle vehicles).

This approach of ISRO vs DRDO, and labeling DRDO "lazy" for delayed projects and now ISRO because of no updates because their operations were strangulated for an year is a very very ignorant approach.

Budgets of all major PSUs has doubled and even tripled from 2014. Last year, ISRO couldn't even spend 50% of its budget in 2020 due to lockdown. So unless they have enough projects and speed to spend money. Their budget was boosted in past few years because speed operations increased many times. Clearly they never lost momentum.

Only 1 launch system from USA needs Russian Engines and they are close to run out of the engines now and building their own engines now. Rest of the vendors in US have their own engines and designs.

No, and 4 tonnes is official safe working load and 4.25 tonnes is absolute one. It will be 6 tonnes (and 15 tonnes to LEO) once SCE-200 becomes main engine.
Yes, I hope it does as last time we had to use a French vehicle for launching our satellite because it was heavier by a slight margin.

Our major issue is launch frequency. Producing components for GSLV Mk3 takes way longer time than PSLV. Indian HLV and SHLV may have their first flight just few years after SCE-200 is tested. But launch frequency is going to remain low.

I know, but bring it don't help much.
Competition is very high, finding forien order is very difficult, since gov of usa/china/Russia/eu don't support it.
Adding mk3 bring isro to achieve 97% of Indian needs.
Best thing about ISRO is low cost for space mission and not launching satellites. Reusable launch vehicle like ones of space x is a huge challenge. ISRO don't have that kind of money, it's like IAF building a force like USAF.

First launch pad has been modified during the lockdown.

What is HLV and SHLV?

For the people comparing launch frequency simplistically,

Every year
US : 15-20 mixed of heavy and upper medium launch vehicles.
Russia: 15-20 mixed of heavy and upper medium launch vehicles.
China: 15-20 (sometimes 30) upper medium and small launch vehicles. Sometimes heavy lift.
India: 5-7 lower medium launche vehicles. Sometimes upper medium.
EU: 6-9 heavy lift launch vehicles.
Japan: 2-6 (Very fluctuating) upper medium launch vehicles. Sometimes heavy lift.
