The serial number should indicate the launch site, here is an example how to understand:-

So far I have not found reference to a Fregat openly ordered for Vostochny. For this launch only a new Soyuz-2 rocket was ordered.

Obvious point to note that the Fregat used by Meteor-M has a launch vehicle adapter (PKhO) for an 81KS type fairing. Rezonans uses the 14S737 fairing.
http://forum.nasaspaceflight.com/index.php?topic=39795.0

Two Fregat were procured, each intended to carry two Rezonans satellites.

Some information can be found in tender documentation for the delivery to the launch site. These sometimes indicate for insurance purposes the contract the Fregat were sourced from.

For Kanopus-V-IK it quotes the contract numbers for the 1st Rezonans pair.

It looks like the 2nd Rezonans Fregat & fairing was intended for Kanopus-V № 3, № 4.

Similar documentation for this Fregat’s delivery to the launch site, does not quote any contract numbers. It does though indicate that the Fregat cost 366,912,000 rubles.

What's the difference between 372PH17 and other Soyuz-2.1B versions? Is it a special version for Vostochny?
Mainly new flight control computer system based on Malakhit-7 with changes to some other instruments.

This is a description in Russian for the 1a version. Google can be used to translate.

Thanks!

So, to sum up in the standard language of this forum:

- The Vostochny Soyuz-2 version is 372RN17 (not PH, that was cyrillic).

- It features improved draining lines for fuel and oxidizer in the 3rd (Block I) stage and central (Block A) stage, as well as the oxidizer draining lines for the side blocks.
- The aforementioned Malakhit-7.
- New BSIUZ (control equipment of on-board measuring instruments level of refueling).
- New telemetry relay system (RTSTsM-1)
- High-speed "subscriber" relay system.
- On-board video.
- A new KhIT BAS-V that doesn't require ZAS, as well as a lightweight BCS-SS (no idea what these are).

I wonder if anyone verified the GNC data during the launch campaign or I wonder if that wasn't part of the written procedure for some reason (as most stages are purchased for a specific launch site and never swapped around) and no-one had the initiative to do it anyway?

How much was the contract value for the Meteor-M 2-1 mission (satellite + launch)? Asking to understand how likely it is they will find funds for a replacement Meteor-M 2-3, considering the quoted $44M insurance.

I think Anatoly Zak addresses exactly that point here: http://www.russianspaceweb.com/meteor-m2-1.html

"At the same time, experts agree that the problem could theoretically have been resolved before launch, if not for the poor coordination between the developers of the flight control systems of the Soyuz-2 launch vehicle and their colleagues working on flight controls for the Fregat. As one poster on the Novosti Kosmonavtiki forum noted: in the deluge of pre-launch paperwork between RKTs Progress in Samara, which built Soyuz-2, and NPO Lavochkin, which developed Fregat, discussing a multitude of legal issues, confirming and reconfirming various agreements and reminders, there was not a single memo attracting the developers’ attention to a different alignment of the launch pad in Vostochny from that of other sites. Obviously, such information was buried in the working documentation on the mission, but nobody thought about the effect of this fact on the launch. The lower echelon of engineers simply missed that detail, while top managers had no idea at all, because, the majority of them lacked the necessary qualifications, the poster said…"

It's written: USD ;) That is, it was insured for 2.6 billion rubles.

I think the Fregat cost is in error in Mr Zak's website (it should be million, not billion), so total costs would have been ~3.28 billion rubles. That is, there's a deficit of ~670 million rubles assuming a full insurance payment. Hopefully then, if political will doesn't interfere, NΊ2-3 could be funded.

Roscosmos has reported the results of technical investigation of the Fregat failure: https://www.roscosmos.ru/24451/
An algorithmic error in Fregat control system program was found which had never revealed itself between 2000 and 2017 in launches from other sites.
Now the second investigation is ongoing to find why it was not found in simulations before the launch.
This message reflects my personal opinion based on open sources of information.

Tentative translation of this Commission report (with Google help ;) )

ROSKOSMOS. CONCLUSIONS OF THE FAILURE COMMISSION
12/12/2017 09:05
The failure commission of Roskosmos under the leadership of Oleg Skorobogatov, deputy general director of CNIIIMash, who studied the reasons for the failure of launching on November 28, 2017 from Vostochny the launch vehicle Soyuz-2.1b rocket with the Fregat upper stage, the Meteor-M spacecraft and the associated payload, completed its work.
 
After reviewing the materials and analyzing the telemetry information, the Commission specialists came to the conclusion that the unpredictable situation was caused by the unpredictable behavior of the Fregat after its separation from the carrier rocket. This revealed a hidden problem in the algorithm, which had not manifested during decades of successful launches of the Soyuz-Fregat bundle.
 
The Soyuz-2.1b carrier rocket worked out regularly, there were no errors in the mission of the rocket and the upper space. The upper stage and payload assembly was put into the calculated point.
 
After separating the upper stage from the carrier rocket, the control system of the upper stage started to issue control action to turn the orbital unit to the desired angular position - the process of spatial orientation of the upper stage began. During this period means of telemetry detected a non-standard angular position of Fregat, which left the calculated trajectory after firing of the propulsion engines.
 
Fregat is a reliable universal unit, which 61 times successfully injected the payload from three cosmodromes (Baοkonur, Plesetsk, Kourou - French Guiana) and delivered more than 200 space vehicles to target orbits. The ballistic trajectory of the launch from the Vostochny cosmodrome passed the necessary inspection and was calculated in strict accordance with the regulations existing in the domestic rocket and space industry.
 
At the same time, there was a combination of the parameters of the launch pad of the cosmodrome, the azimuths of the launch vehicle and the upper stage, which had not been met before. Accordingly, it was not detected during ballistic trajectories ground tests conducted in accordance with current techniques.
 
Having carried out a comprehensive analysis, the members of the commission believe that the manifestation of this incorrectness of the algorithm might not have occurred when launching from Vostochny the same payload with the same upper stage, on the same carrier rocket. Launch would have passed normally, for example, in the summer, or in the event that the areas of fall of the separated parts of the launch vehicle lay apart from the selected ones.
 
For an immediate correction of the situation, the algorithm of the spatial orientation control system of the Fregat upper stage and existing regulations will be corrected, and instructions have already been given to develop new modern integrated methods for simulating and controlling the flight characteristics of launch vehicles.
 
A separate commission will thoroughly analyze organizational issues and prepare proposals for assessing the responsibility of officials for accepting or not taking decisions that have affected the completeness of pre-launch training for the mission.

Is this turgid paragraph intended to mean that a launch to some other orbital inclinations would not have triggered the guidance error? What relevance does the season have?

ROSKOSMOS. THE RESULTS OF THE WORK OF THE COMMISSION ON ASSESSMENT OF THE ACTIVITIES OF OFFICERS RESPONSIBLE FOR THE PREPARATION AND STARTING OF "METEOR-M" CAS No.2-1
12/27/2012 18:52

In accordance with the findings of the emergency commission on the launch of the November 28, 2017 launch from the EAST spaceflight "Meteor-M" cosmodrome No. 2-1 and the associated load, the cause of the emergency is the imperfection of the software algorithms of the control system of the Republic of Belarus "Fregat". The Emergency Commission noted that calculations of ballistic trajectories were conducted without deviation from the procedure regulated by the current regulatory documents. Since the order of ballistic calculations and the order of their verification did not provide for the use of separate parameters of the angular motion, the incorrectness of the algorithm of the control system of the Republic of Belarus "Fregat" was not found.

Based on the findings of the emergency commission on the causes of the contingency situation, the Commission for Evaluating the Activities of Officials Responsible for the Preparation and Launch of Meteor-M Spacecraft No. 2-1 from the EASTERN Space Center on November 28, 2017, analyzed the preparations for launch and compliance of the actions of the leaders their official duties.

The Commission noted that the development organizations did not pay sufficient attention to an analysis of the possible causes and consequences of potential inconsistencies that are related to the specifics of the launch of the Fregat carrier in the Soyuz carrier rocket from the EASTERN space center and the development of possible measures to prevent their manifestation. Thus, the requirements of normative documents regarding the analysis of possible failures and the criticality of their consequences were not met to the proper degree.

In addition, the officials of the State Corporation "ROSKOSMOS" and the main development companies responsible for the creation of the space complex and its components did not take comprehensive measures to ensure proper control and coordination of work.

All this in aggregate contributed to the fact that the factors, the combination of which led to an abnormal completion of the mission, remained undetected in preparation for launch.
For improper performance by the leaders of the duties assigned to them, the Commission recommended that disciplinary sanctions be imposed on them in the form of reprimands.
The instructions for reprimanding were issued to: Andrey MAZURIN, Executive Director of Roscosmos for the Removal and Operation of Ground-Based Space Infrastructure, Victor Chaporgin, Director of the Quality and Reliability Department of Roscosmos, Oleg Gorshkov, Director General of TsNIIMash, Alexander KIRILIN, Director General of Progress, To the Director General of FSUE "NPO im. Lavochkin "Sergey LEMESHEVSKY, General Director of FSUE" NPCAP im. Pilyugin "Yefim MEZHIRITSKOM and Director General of VNIIEM Corporation Leonid MACRIDENKO.

The commission also defined systemic measures and organizational measures, the implementation of which is aimed at preventing future emergencies for identified reasons.

Russia says satellite launch failure due to programming error
December 27, 2017 /  7:11 PM
MOSCOW (Reuters) - Russian Deputy Prime Minister Dmitry Rogozin said on Wednesday the failed launch of a 2.6 billion-rouble ($44.95 million) satellite last month was due to an embarrassing programming error.
Speaking to Rossiya 24 state TV channel, Rogozin said the failure had been caused by human error. 
The rocket carrying the satellites had been programmed with the wrong coordinates, he said, saying it had been given bearings for take-off from a different cosmodrome - Baikonur - which Moscow leases from Kazakhstan.
“The rocket was really programmed as if it was taking off from Baikonur,” said Rogozin. “They didn’t get the coordinates right.”
