Yes! It is ok, because- (i) India has a stated "no first use" policy. (ii) India is a democracy in true sense. Of course there are certain bigots, however the constitution is steadfastly secular and doesnt grant any special rights to any groups. (iii) India is not against the existence of any...

Oh I see, I am all for the peaceful applications of space. Iran also has the right to pursue the same. However as far as ICBMs go, I will not comment. It has a lot of political dimensions that I do not wish to get into. I am certainly no fan of religious theocracy that Iran is at the moment. As...

Hi, Actually I'm an aerospace engineer myself. I just love these things. I am a huge fan of India's space research efforts. I always compare our efforts with that of China. Its nice to know that Iran is also in the race. After coming to this thread, I gotta know that Iran is actually working on...

Can anyone shed some light on ghaem I'm not talking about fictitious stuff, but hardcore engineer stuff. Any test launches?

Yes in that way you are right beyond LEO, it can hardly do 1.7t. But you should realize that PSLV is actually an old rocket-- designed in late 80s/early 90s. So a lot of what it uses is not really efficient by modern standards. However if you see, GSLV MK-3, it uses solids only as boosters and...

Hi @TheImmortal I see, for a serious space program, Iran would have to get serious about cryo/semi cryo engines. And most importantly the budget. I like Iran's efforts in space research. I am amazed by the fact that they started off from old soviet engines and reached where they are now...

Also this is factually incorrect as PSLV can place a 2.5t to LEO.

Hi @skyshadow , @SOHEIL What is Iran's competency in designing semi cryogenic or fully cryogenic engine? What are the areas do you feel, Iran should work on to improve their space program. And finally what is the max payload delivered by any Iranian rocket to lets say LEO and GEO? It amuses me...

Hi! What is the likely engine for this Iranian rocket? Does it use hypergolics? or Does it use kerosene based semi cryogenics? Or is it fully cryogenic? Please enlighten, thanks!

Yes I know, thats why I am saying that PN will find it extremely difficult to deploy and sustain their Chinese ships in IOR region for any meaningful time (At least a month or more). For that to happen, PN will inevitably need a nuclear powered boat- somewhat on the lines of Arihant. So, as of...

This information is at least 10 years old. K-4 has entered the scene and ASL/DRDL is working on K-5 right now. With K-4 and later K-5, IN will be able to target even the northernmost parts of China from bay of bengal waters. The best place to park Indian SSBNs will be southern bay of bengal or...

Hi! This isn't about the arihant, however I was wondering if you also use bash scripting a lot with your Linux distro i.e Ubuntu Also yes that pic appears to be that of Arihant and if one looks closely they can see her sister boat i.e the Arighat as well in a similar pic that was posted by...

Hi shaheen, the dia of the silo is 2.3m even as of now in arihant. So yes it can accommodate K5 even now. However what will need to be changed is ballast tanks etc to accommodate for change in buoyancy when a 20-25t missile is fired off one of the silos. The weight is significantly higher than...

Hi shaheen, in all likely hood K5 is going to have a 2m diameter. The assumption that they'll have 1.4m dia is not correct because k4 already has that dia and there's only so much range you can extract from that system without radically changing the propellant. HEMRL is working on NEPE based...

Hi @Allahistan This message is in response to your remark about the kind of AI work happening in India. Before I begin writing my answer, let me tell you that I have not only worked on nonlinear functional analysis and incorporated very mathematically rigorous RL based control for nonlinear...

Hi @denel Absolutely correct, I completely agree with you. I myself have worked on "unsupervised" reinforcement learning based systems--which are many leagues more advanced than data driven approaches. I feel, there are areas where RL can be effectively integrated and then there are those areas...

Hi @Allahistan It is possible to design way point based navigation "without" GPS entirely. One can estimate their location in earth-fixed inertial frame using the position equations i.e by integrating them. However for that one would need good sensor data for V,alpha,beta and IMU data. This...
