Thanks for all the pics you post....very insightful. Board to the right looks pretty rough....any info on where the controllers and processors are sourced from (imported?) for some of these things?

I am not sure about the percentage of import but believe me most of these systems are indegenious. Only very few companents are imported and that too will be indegenioused soon

Radiation proof electronics is one of the areas where traditionally Japan and West dominated in terms of long life components, so kinda curious why the processor design and manufacturing ability is not trickling down into civilian gadgets even if they are 16 to 32 bit architecture. Granted we have pretty good theoretical and design base in electronics at an academic level including Indian origin NRIs.

PRATUSH - Probing ReionizATion of the Universe using Signal from Hydrogen.


This is a proposed radiometer in lunar orbit that will help in obtaining tremendous amount of information about the first stars and galaxies in our Universe this one may be selected as a payload in Chandrayaan-3

It means it will be with lander on moon surface.

but in cy3 there is no any orbitor.
Two three years ago, there was an article in IDRW or IDN that ISRO is planning to place a telescope like Astrosat into lunar orbit instead of earth.

This might be that one. And since this isn't as complex as Chandryaan-3 except significance that it needs to go to lunar orbit, it will come sooner than we think (once project is finalised).

But it won't stay in orbit. Entire assembly will land on moon and use Cdy-2 orbiter.
Only the Lander and rover will land on the lunar surface. The propulsion module will stay there in the orbit for a while , for atleast 6 months, more over the PRATUSH payload which will be used in this mission is called PRATUSH-C3 . Its more of a tech demonstrator. It will be a precursor to the actual PRATUSH payload which will be launched some time in future.

Radiation hardened processors and related electronics are generally very high lithography nodes ~180-200 nm or even bigger. These are not suitable for general public use.

True but if you have the practice then you would attempt to bring these things like microprocessors into local markets. It is just hard to imagine what is domestic 100% and what is not....even 60 to 90 nm was not long ago in consumer products.

Xposat is a unique mission which no other country tried before. Read about ISRO s Xposat mission.

Isro is also developing a new Nano-Satellite launch vehicle (NSLV) apart from SSLV.

ISRO also got approval to develop fully reusable TSTO

Fully reusable Air - breathing TSTO , it needs a turbofan engine to take-off from runway.
