Leo is not space my friend it's just to experiment basic hsf
Ehh?? Even ISS and Chinese Space station are in 400KM LEO, Gaganyaan will also be going to same orbit, then how it's different

Read line carefully
Due to the assumed constraint on the time available for the development of the vehicle, both the L110 and indigenous CS were considered non-viable. Accordingly, non-cryogenic options with solid boosters came into prominent focus once again. The candidate configuration finding place in a draft project report of 1988 is as follows:
but they said they can develop L220

Anything above Carmen line is generally accepted as Space. Carmen line can be any where from 70KM to 100-120KM from Surface.
So 300-400 LEO orbit and indeed well inside space.
I was literally saying ki mk3 has just enough capacity for experimental human spaceflight not sustained that mean gaganyaan itself is just 15-20 days experiment even then many required module for hsf is not worked out

They will have to eventually shift to sce200 hsf capacity . They delayed sce200 for gaganyaan that is literally a treagedy

No, the gap between production capabilities of India and them was always this much. It's India who used to launch small PSLVs instead of MSLVs and HLVs.
Budget constraints I guess since hlv has been in books for arround a decade....

Making an HLV MLV takes much more time than a small medium SLV. That's what I'm saying if ISRO will try to fly more GSLV & LVM3 instead of PSLV, it's launch frequency will reduce naturally.

It is foolish to simply expanding the budget in space program without considering the demand of economy and technologies.

Check the below chart of Chinese launch frequency since 1970, you can see it has been growing closely with Chinese economy:

Actually our economy is growing at rapid rate after 2010 more number of private companies are into space then ever in Indian history since past 4 year but i see no dedicating from government budget towards launch. Less no of launches actually shaking trust of pvt investment into Indian space economy many startup has started registering them self in usa and Europe.

In 2019 india launch 5 rocket. No of rocket launchers has been on decline after that. Only in 2016 they launched that much rockets

There is only one launch in 2021 and only one in 2022 so far do the math

Shear amount of backlog they have in terms of satellite launch is enormous. They created a fake demand of hsf while satellite launch schedule is thrown into dustbin

PM Modi To Inaugurate IN-SPACe Headquarters At Ahmedabad On 10 June, Move To Boost Private Sector In Space Activities

Prime Minister Narendra Modi will inaugurate the headquarters of the Indian National Space Promotion and Authorization Centre (IN-SPACe) at Bopal in Ahmedabad, Gujarat, on June 10.

IN-SPACe, approved by the Union cabinet in June 2020, will be the nodal agency that will allow space activities and use of Department of Space-owned facilities by non-government private entities and ensure greater private participation in the sector.

The Indian Space Research Organisation (ISRO) made the announcement of IN-SPACe headquarters’ inauguration on its Twitter handle.

“I am happy to announce the inauguration of IN-SPACe Headquarters at Bopal, Ahmedabad by Hon’ble Prime Minister Shri Narendra Modi Ji on June 10, 2022 at 15:45 Hrs. We are looking forward to working with the industry and ISRO to grow the space sector, Pawan Goenka, Chairman of IN-SPACe tweeted.

I thought the expansion of Chinese launch frequency had less to do with its economy and more to do with foreign launch orders China started to receive after warming up relations with US. China of 1970s and 80s was too poor to have large scale internal consumption in aerospace sector.

Significant change happened in 1995 when under Bill Clinton, One of the biggest Satellite manufacturer from US gave contract to Chinese and transferred a lot of confidential IPs to them. This lead to a rapid growth in Chinese capabilities that they were able to fly human rated rocket within 10 yr and did first human launch by 2003.
Bill Clinton was the biggest bastard in this regards. He personally led movement of a lot technological capabilities to China in 1990s.

I don't understand why ISRO's HLV max payload is capped to just 7.5Tons, while they are developing new satellites with I-8K bus.

Also I don't understand why our rockets have very high dry mass... just compare Centaur and C-25, Centaur carries 20 tons and C-25 carries 25ton fuel, but dry mass of Centaur is just 2.5tons while C-25 is more than 5 tons (new C-32 stage weighs 7.4 tons). If C-25 had weighed just 3 tons ,then Mk-3 would have had 6tons to GTO payload right now while the upgraded Mk-3 with SCE-200 would have 8tons.

Check again.
Between 1990 and 2006, the highest yearly launch number was 6.
From 2007, the number started to jump from 8.
American already banned usage of Chinese rocket since 1999.
