Small clarification from my previous assessment.
From a new Iranian article posted on 7th June 2020, the third stage is presented as the solid-propellant Arash-24, with a purported mass of ~100 kg. The mass of the Salman-1 second stage being about ~300 kg.
And from the Mission Control screen, we know that following the second stage's ignition at T=150 seconds, a third burn was performed at T=420 seconds.
This means that currently there are only the Arash-24 solid propellant third stage and the Noor-1 satellite orbiting the Earth.
The Salman-1 solid propellant second stage reaching only a velocity of 5'250 m/s at cut-off, after 70 seconds of burn, and a 403 km altitude, simply re-entered the atmosphere, unable to reach orbital velocity.
This orbital insertion velocity of ~7'650 m/s was achieved with the third stage Arash-24, reaching an apogee of ~444 km.
Thereafter, the Noor satellite used its own six cold gas thrusters to separate from the third stage and manoeuvre in orbit, orienting its camera toward the earth's surface.

▲ 1. Flight Profile Qased-e-Noor-1 on 22nd April 2020.
Meanwhile the same article announced the launch of Noor-2 satellite this month (June 2020).
when is take off?
With this current administration we cannot expect things to be done properly in the space sector, lets see how the next administration handles the space program. We should have had dozens if not a hundred satellites into orbit by now.No time was given,..they just said its ready to be delivered and will have to be placed in 36000km orbit.
