What about issues related to the new launch site? Is there any particular problem for the first mission of the Soyuz 2 1A from a new location?
I'm thinking about mision-specific flight profiles or issues related to lack of ground visibility windows during the rocket/upper stage burns.

Don't they use closed-loop guidance for the upper stage? If so ground coverage doesn't really matter as far as mission is concerned. However for the first flight they will probably want as much telemetry as possible, so trajectory will be chosen based on the ground stations coverage.
BTW - does anybody know what's the destination orbit for the launch? If it's SSO, then there will be plenty for GS passes over Russia for next several orbits (assuming usual 94° inclination).

Using Gunter's Space Page, I added the masses of all three satellites on this mission and saw that the total payload mass will be 507 kilograms (1,117.74 pounds).

Thank you for your answer asmi. What about contingency situations? I'm thinking about anomalies which may be recovered if detected promptly, like software or attitude issues.
I have Mars 96 in mind, but I also found this article regarding the launch of two Galileo satellites in 2014, which may be even a better example:

It is now believed that while Fregat MT upper stage fired correctly and with the correct amount of thrust, an orientation error during this second burn (thought to be due to a software error) left both Galileo FOC FM01 and Galileo FOC FM02 satellites in an incorrect orbit

The final assembly of the payload section, which would be carried into orbit during the first mission from Vostochny, began at the new Russian spaceport in the middle of April 2016.

Engineers at various Roskosmos entities including the TsENKI ground processing company, the VNIEEM satellite manufacturer and Moscow State University, which was responsible for scientific instruments, began the integration of three satellites with their Volga upper stage, Roskosmos announced on April 15. All three spacecraft -- Mikhailo Lomonosov, Aist-2D and SamSat-218 -- were integrated with the upper stage.

According to Roskosmos, the fully assembled payload section would be rolled inside its protective fairing on April 18. The resulting upper composite would then be transferred from the spacecraft processing building, MIK KA, to the vehicle assembly building, MIK RN, for final integration with its Soyuz-2-1a rocket.

The integration of the launch vehicle would be completed before the end of the week for the rollout to the launch pad on April 23.

The first liftoff from Vostochny is set for April 27, 2016, at 05:01:21 Moscow Time (22:01 EDT on April 26)

ROSCOSMOS: Specialists began to assemble Soyuz-2.1a nose section

April 15, 2016

Specialists of ROSKOSMOS enterprises began to assemble the nose section of integrated launch vehicle Soyuz-2.1a at Vostochny cosmodrome. The nose section will consist of upper stage Volga and three spacecraft - Lomonosov, Aist-2D and Samsat-218.

The spacecraft electrical and mechanical interfaces are connected to upper stage Volga. On Monday the encapsulation will be performed, following which the ascent unit with the payload will be transferred to the integration and test facility for launch vehicles. The assembly of integrated launch vehicle Soyuz-2.1a is planned to be completed by the end of the next week.

Medium capacity launch vehicle Soyuz-2.1a will insert into orbit spacecraft Lomonosov, Aist-2D and Samsat-218. The spacecraft developed in collaboration with students of the Moscow State University and Samara State Aerospace University are designed for scientific experiments. The first launch from the first Russian civilian cosmodrome Vostochny is scheduled on April 27.

The roll-out is scheduled for 23:00 Moscow time on April 22 (20:00 UTC, April 22).

It seems like kind of an unusual fairing system, as its the Lavochkin fairing, which normally is used for Fregat launches. That means that the Volga sits in a PxO that is far too large for it.

Given the NOTAMs and the expected performance of the launcher, can some orbital parameters be deduced?
(perigee X apogee X inclination)

Usually the drop zones are standard for inclinations. So inclination and RAAN can be approximated very well, but the apogee/perigee I don't think so. The only exception are SSO missions where the inclination determines de apogee/perigee.

Is it a good assumption that the grand opening of one of Putin's Great Works (TM) will be live broadcast-ed? If yes then I'm going to move this one to the live section.
