Congratulations to Iran on the launch.   Maybe their launch rate will finally increase.

I checked the other night-time launch (omid) , and I think its a different video, considerably slower ascending. Possible 3rd stage?

Is the tracking elements for this launch out yet? Strange to see that there's no independent confirmation of launch success for so long (the time I gave for the claimed launch time is wrong: 03:00 Tehran time = 23:30 UTC on February 2nd). Is it really in orbit, or is this a deliberately wrong  claim similar to the 2009 NK attempt?  :-\

If I recall correctly, the August 2008 launch failure was originally reported as successful, then later as a suborbital "test flight" (despite it being obvious that it was carrying a satellite). Could be something similar, or it could be that confirmation has simply been delayed.

The payload was apparently built at Elm-o Sanat University (University of Science and Technology). so the name  'Navid-e Elm-o Sanat' I think refers to 'Elm-o Sanat U's Navid satellite'. Navid = herald, gospel, good news

The lack of Two-Lines from this launch on the Space-Track website makes a launch failure more and more likely.

On the other hand, the orbital inclination could be so different from the two earlier satellites that the satellite and upper stage are being tracked but not yet assigned to this launch.

The first tracking data has just appeared on Space Track. I can't just copy the TLE because of useage rules, but think that it's probably OK to say that it shows the statellite to be in a 375 x 276 km orbit at 56 degrees inclination.

Edit: There are slightly different ways to compute apogee and perigee, so the numbers above shouldn't be taken as significantly different from those Liss posted.

Of course. Mine are from propagating one orbit and reportin minimum aand maximum heights over 6378.14 km.
I'd say launch time was close to 00:10 UTC = 03:40 local time.

FWIW, I applied

Cos(Orbit Inclination) = Cos(Launch Site Latitude)*Sin(Launch Azimuth)

and came up with the launch trajectory shown in the attached figure.  If it's correct, I wonder if Iran let Turkmenistan, Uzbekistan, Kazakhstan know they were going to be overflown.

My calculations give 0004 UTC +/- 1 min on Feb 4 using the TLEs and comparing with the Rasad launch (whose launch time was announced).

Bob says he gets 0004:40 UTC.

Interesting. Earlier launches were OES.0001, OES.0002, UIS.0001.

One could speculate the letters are related to the payloads (Omid, Omid, Rasad, Navid), and that the first digit being '2' in this case reflects the block change in the Safir (thrust upgrade).

This article http://irna.ir/News/Politic/Satellite-%E2%80%98Promise-of-Science,-Industry%E2%80%99-put-on-orbit-successfully,-Defense-Min/30795827
says that the satellite was built by Sharif Univ of Technology, rather than by IUST as the earlier stories had claimed. They translate the name as 'Promise of Science and Industry'. I guess "Navid' is one of those all-purpose words :-)

Wasn't Rasad reported to be a block 2 though?

Also, I would say the upper stage in the video looks wider than those on previous launches, and as somebody mentioned before, the initial ascent does seem slightly slower than the previous launches suggesting that the rocket has a greater mass.

Again, very interesting. Certainly subject for further research.

I'm interested in the sites near Tabriz and Meshad because there's been a lot going on around Tabriz and I keep wondering if Iran has repurposed the Shah-era CIA TACKSMAN 2 site (37.2957 N , 58.9152 E) outside of Meshad.

I have finally got around to running the orbital data from Space-Track through my own software and come up with the following data.

Using both objects A and B, catalogue numbers 38075 and 38076 respectively, the estimated launch time comes out as being 00:02 UT on February 3rd.   From the reported launch time of 05:34 local time and allowing for the difference in time zones I think that this will correspond to an actual launch time of 00:04 UT, especially since the only orbital data are for more than 19 hours after the launch (these are element sets 5, so will Space-Track please issue sets 1-4?).   The later after launch the TLEs are the more inaccurate the launch estimate using my own software.

The orbital parameters for the two objects are as follows (assuming a spherical Earth, radius 6,378 km):

38075      56.02 deg incl    91.03 min orbital period     276-374 km altitude

38076       56.03 deg incl   90.95 min orbital period     274-368 km altitude

The above data are in line with Jonathan McDowell's posting on Facebook yesterday evening.

Is this the satellite that is supposed to have an in-orbit manoeuvre capability?

I guess it's also on Heavens Above.   I download the two-lines each day and use Orbitron on my laptop.

Concerning the reports of an enlarged upper stage: I have compared photographs of the recent launch vehicle, the one which launched Rasad and the earlier one, which was on public display around the time of the Omid launch. Apparently, they have all the same dimensions.

A visible difference of the vehicle on display was, that the two protrusions on the upper end of stage 1 are smaller than on the later vehicles.

According to the Israelis, apparently the camera lens on the satellite is a stock 8-24 mm lens from a Sony digital camera....

Spysat? If this thing's a spysat, then the Iranians should sell them across the globe for universities around the world to spy on the sport teams of the other universities....  ;D

Sadly, Israel hypocritically calls anything launched either by or for an Arab country a "spysat", whether or not it has an imaging system on board.

Israel is scared of the Arab countries gaining the technology which it has used for more than 15 years.   My worry is that Israel might have some form of basic ASAT capability and they might use it against an Arab satellite.

Early this morning I was unaware of this new thread being created, so posted the following to the original Iranian Space threat:

I have finally got around to running the orbital data from Space-Track through my own software and come up with the following data.

Using both objects A and B, catalogue numbers 38075 and 38076 respectively, the estimated launch time comes out as being 00:02 UT on February 3rd.   From the reported launch time of 05:34 local time and allowing for the difference in time zones I think that this will correspond to an actual launch time of 00:04 UT, especially since the only orbital data are for more than 19 hours after the launch (these are element sets 5, so will Space-Track please issue sets 1-4?).   The later after launch the TLEs are the more inaccurate the launch estimate using my own software.

The orbital parameters for the two objects are as follows (assuming a spherical Earth, radius 6,378 km):

38075      56.02 deg incl    91.03 min orbital period     276-374 km altitude

38076       56.03 deg incl   90.95 min orbital period     274-368 km altitude

The above data are in line with Jonathan McDowell's posting on Facebook yesterday evening.

Iran is very far from developing a spysat , the Navid is a experimental observation satellite made by Iranian university students.

Has anyone a good explanation on the nature of these "pieces" dropping off the vehicle?
Could it be ice coming off a possible LOX-tank on the lower or upper stage, or is it combustion related?
Any ideas?

These are early days and things may change, but SatEvo, using the available Space Track TLEs, is predicting Navid will reenter in mid-April. The rule of thumb uncertainty is around two weeks at this point, so "sometime in April" is a reasonable paraphrase.

How closely related to the original Scud missile is the Safir. I know that it's probably derived from the North Korean Nodong, which itself comes from the old Scuds, but is there still some similarity to the Scud (tank diameter, propellant etc.)?

An interesting article from 2011 , right after the launch of Rasad-1:

Quote
The head of Iranís space agency acknowledged Sunday that the cameras aboard Iranís past and planned satellites are too poor to give useful images, but said the country is now working on a satellite to be completed in four years that will produce useful images.

The government has boasted of the images sent to earth by the Rasad (Observer) microsatellite that was orbited June 15. But while the regime has spoken of the pictures, it has not released any of them to the public.

On Sunday, Hamid Fazeli did not boast of the photos from outer space. In fact, he said even the Amir Kabir, Navid and Zafar that Iran is planning to orbit in the next few years have cameras that take pictures of very low resolution and limited utility.

But he said the space agency is now working on a new satellite called Pars-2 with a camera that will have a resolution of five meters, meaning it can pick out objects that are five meters or 16 feet across.

Iran has not described the resolution of the camera on board the Rasad, which is still orbiting the earth. But it has given the resolution of another camera being prepared for orbiting. And that camera will provide photos only 1/800th as good as satellite photos that are available commercially.

A few months ago, Hossain Bolandi showed off the Navid satellite he is working on. It weighs 50 kilos, triple the size of the just-launched Rasad. Bolandi said the camera on the Navid would be able to see objects more than 400 meters across or the size of four football fields.

But commercial satellites like the GeoEye1 that are currently in service show objects only 50 centimeters (20 inches) across and US spy satellites are understood to discern objects as small as 1 centimeter (a half inch) in size.

Fazeliís statement that the Pars-2 in four years will see objects five meters across will still mean that commercial imagery will be 10 times better than what the Islamic Republic is aiming for.

Is Navid's cots camera comparable to that of  Unisat-4 ?

Quote
The UniSat-4 microsatellite hosts two CCD-based programmable cameras. The CCD sensor contains 640 x 480 pixels. The JPEG compression algorithm is used with the compression factor selectable by ground command. The two cameras have different optics and resolution. In this way, UniSat-4 is able to take pictures of the Earth's surface in the northern hemisphere.

One camera is provided with optics of 2.5 mm focal length, providing a FOV (Field of View) of 84.6ļ and a resolution of about 0.8 km/pixel. The second camera is equipped with optics of 6 mm focal length (36.8ļ FOV) providing a 0.3 km/pixel resolution. The FOVs of the two cameras are overlapping to take imagery of the same target area with different resolutions.

Iranian satellite sends photos from Earth
1390/11/21 - 11:12

Tehran, Feb 8, IRNA Ė For the second consecutive day, Navid satellite sent to stations the latest photos it has taken from Earth, project manager of Navid Satellite project, Hossein Bolandi said.

'Navid satellite took pictures from Hormuz Strait and also from different parts of the Islamic Republic of Iran,' Bolandi added.

He pointed out that Navid Satellite had a good performance in the seventh day of its mission in space and all its systems and subsystems are functioning well.

'Navid orbits 16 times around the Earth every 24 hours and it passes six times from above Iran,' Bolandi added.

The life span of the satellite is predicted to be two months, but it seems that the satellite will function more than two months.

'Iranian experts managed to successfully launch third domestically-built satellite into space which is a great achievement for the Islamic Republic of Iran,' he added.
