Possibility of using Ghauri and Shaheen for satellite lunching

[باپ]

Looking at the weight carrying capacity of a ton and flight altitude of 300-690 kilometre, is it possible to use Pakistani ballistic missiles as SLV.
YES we know what India has and done and doing, so no need to spam this thread with ISRO and DRDO bravado.
Stick to the question asked and analyze technicalities.

We Have Already Developed Indigenous Capabilities In Rocketry I Am Pretty Sure That This Expertise Can Be Used In Civillian Space Sector

There is a tiny assumption in this childish post by the page pakistan affairs.

Going into orbit does not require you to simply reach an altitude. You would simply fall back down even if you went up 2000 km in altitude. You need one thing additional: I sideways velocity of up to 8000 m/s (depending upon orbit altitude and launch direction).

Please Google "newton's cannonball".

You can launch very small satellites perhaps by modifying the s3. But that picture is absolute pseudoscience.

@JamD virgin galactic offers launch of 450 kg satellite on a much smaller rocket albeit while being slung and fired from a Boeing 747 at altitude. So rocket size may not be the problem.
Looking at the third stage of Shaheen-3 which is quite big,it may be possible to attain orbital velocity by using the third stage liquid motor?

I believe you are talking about the LauncherOne system.

A- That highlighted portion is a BIG deal. Most of the rocket's fuel is expended lifting the initial large mass from the ground through the thick atmosphere (hence the whole idea of staging).
B- Have you seen the mockups of the LauncherOne? It itself is as big as shaheen 3 or maybe even larger.

Sadly, rocket size IS the problem and there's no cheating physics. You CANNOT launch any decent satellites to any decent orbit with a shaheen-3 sized missile.

You should try to compare size of S3 with even SMALL SLVs, used only for LEO. You'll see what I mean by size being the problem. There is no great conspiracy here.

Well yes I have seen the actual full scale mock up, that's why making the comparison.
VirginOne is 16 ton rocket and gets launched from 15km altitude. Shaheen is much heavier than that I guess.

Before anything. Can you answer or do you know of Pakistan's prowess of ejecting a payload (satellite) into the space (whichever orbital slot)? Releasing a satellite from missile is a technical process. Which is different from Missile's last stage coming back to earth and crashing.

Ghauri would make an ideal launching vehicle. If you combine three of these, like what you see in the US Satellite launch vehicles, with some more extensions of fuel, these would lift a Satellite to the lower orbit (200-2000 KM). For GPS and Geostationary Satellites, you'd then need to hit over 35,000 KM (the end of mid earth orbit and the starting of the upper earth orbit).

The best way to launch Satellites for developing countries is to use liquid fuel systems (older ones), as the Satellite launching doesn't require very sophisticated electronics or missile dodging capability, etc. You can simply add more fuel and extend the range to whatever orbit you need to get to. For Pakistan's needs, I think for now, the lower earth orbit would be where she'll leave her Satellites.

GPS satellites = 20K

GPS satellites = 20K

There is nothing at 20KM. Those are more like SatCom baloons than Satellites. A modern SAM can take out crap at 20 KM. Current GPS systems are at 200KM-3500KM (mid-the beginning of the upper atmosphere).

Modern science has gone beyond the traditional norm of GPS's, etc at 2000KM!! In the first two generations of Satellites, the GPS were sent up between 2000 KM and 3500 KM (beginning and the end of mid-upper atmosphere), while the Geo stationary Satellites were sent much higher for reduced speeds and Orbit time, from 3700KM and above (Upper band of the upper Atmosphere). But as the technology and science grew in this area, the newer Satellites are different (India and China are STILL using tech and process compared to what was out there when the US launched its GSP starting the 80's).

For the past decades, the GPS and the Geo-Stationary Satellites are being built in one package primarily due to high processing power of information simultaneously on GPS as well as Geo-data, including SAR mapping, etc, supported by higher Solar output generators available with higher powered Radio wave / Broad Spectrum frequencies. This wasn't possible 20-30 years ago due to the previous generation of the computational power and systems.

In the above image taken from Geo-Stationary Satellites sent to do R&D and exploration in the outer space around the Moon, you can see the Earth with thousands of man-made objects—95 % of them “space junk”— occupy low Earth orbit. Each black dot in this image shows either a functioning satellite, an inactive satellite, or a piece of debris. Although the space near Earth looks crowded, each dot is much larger than the satellite or debris it represents, and collisions are extremely rare. (NASA illustration courtesy)

I like the idea of developing satellite-launch capabilites but I wish it were as simple as OP suggests.

What's your qualification in this field? This is when that scene from that movie I saw a while ago becomes a reality. A man is trying to teach Japanese to a Monkey. Well the result is that the Monkey runs away to the trees frustrated and the man wants to bang his head on a wall with Frustration.

Your link provides details on the CURRENT GPS system. If you read CAREFULLY, my post will tell you that the first two generation of Satellites, including the current GPS systems were all new concepts and for the lack of a better term, exploratory. But today, and in 2016 (NOW), the space tech has advanced a LOT since the launch of the GPS> And everything is on a much different scale. For future stuff, you don't see links on the current GPS. You follow the NASA. What I posted, has elements from NASA and I had outlined that below.

Please don't waste time in constant back and forth because you want to be "right". You should learn a topic before constant back and forth showing lack of proper knowledge on the subject.

 

[Imran Khan]

why should we launch our own sats first place ? we launch sats after a decade or so .
