No translation problem, the article clearly stated that Iran is not as advanced as North Korea:There is a problem with google translation of the article. The correction:
“IRGC is trying to smooth out and downplay its space launch capacity by separating Nour and the third stage.”
2. The title is made up by you and the article does not say Iran getting closer to NK or China.
3. Official statement is that “Salman was successfully tested”. If it reentered the earth, it did its job successfully and reentered as planned.

اگر سپاه بتواند موشکهای بالستیک با سوخت جامد و پرتابگرهای متحرک را توسعه دهد، به روسیه، چین و کره شمالی میپیوندد که تنها کشورهای جهان با موشکهای بالستیکِ متحرک هستند. حتی ایالات متحده نیز فاقد موشکهای متحرک است که به حملات غافلگیرکننده اختصاص دارند.
If the IRGC can develop solid-fuel ballistic missiles and mobile launchers, it will join Russia, China and North Korea, which are the only countries in the world with mobile ballistic missiles. Even the United States lacks mobile missiles dedicated to surprise attacks.

While Iran has currently only one Salman rocket stage orbiting the earth, but with no published pictures on the internet to this day, North Korea has two since 2012 and 2016.
And one of them even imaged as late as last night!
The Kwangmyongsong space rocket's 3rd stage, photographed here from close range in its horizontal assembly and processing building of Sohae Space Center, with a much larger diameter of 1.25 m (Salman R/B ~0.9 m), that is similar to the Safir-1 space launcher, and launched on 7th February 2016 with the 200 kg heavy payload Kwangmyongsong-4 earth observation satellite into a Sun Synchronous Orbit:

But as previoulsy feared last week, photographed under very difficult environmental conditions caused by a Moon illuminated at 88.8%, a hot and hazy sky, producing the most annoying intense bright white sky background (removed before upload), and resulting in a very poorly contrasted faint trace of the rocket stage's pass of an estimated magnitude dimmer than 8, but revealing nonetheless a clear brightess variation (rotation) with a peak-to-peak of about ~7 seconds.
As imaged from a 450 kilometer range last night (calibrated with astrometry.net):

Its a quite large 800-850kg third stage with 6 thrusters. Not a Arash-24, 240kg small kick motor.
Brugge is not far off and both of our analysis is not just based on guess.
He has about the same results as I on many points.
His payload estimate is too low because he estimated a 150kg fairing/shroud which is too heavy for this diameter.
The way to analyse it, is to look at the delta v Salman produces (known from the published graph). Based on it we know ~900kg heavy "something" sits on top of it (sat, guidance system, adapter, fairing, kick stage and gas thruster "bus").
The upper stage orbited and must be still in orbit.
Side effect of this analysis is that the performance of the Salman is now known and it is very high.
btw. there is just one Salman variant known.
It will look like this:
This should be a old mock-up of what the Saman+kickstage should have looked.
As for payload estimation: Depends on miniaturization level
If guidance and batteries weight just 50kg total, payload fairing just 50kg, and cold gas thruster assembly under 50kg... then yes even over 100kg payload would be possible, but these are parameters that are hard to estimate accurately.

The third stage had to provide over 2500m/s delta v.
So from that 900kg Salman lifts 800-850kg must be spend on the thrid stage and all the equipment. What remains is 50kg with a large error margin of +100kg or -20kg.
50kg sounds realistic.
That Peter Pry is far off with his numbers.

So where do you get 50KG based on a 6U Cube Sat outlay? (outside your margin of error)
What do you think the function of the third stage is now? Can it have other functions beside navigating around?
wow i hope they mean operational
