Any idea why the fairing was rotated vertical? That's not normally done for the commercial launches.
In the press release, it is written that it was done for the charging of Luch-5A's batteries.
I don't understand the necessity of verticalising the satellite...
And do you know what the "H" stands for ?

From an ISS Reshetnev PDF from 2007, they had this platforms:
Express-1000A: Loutch-5A/B
Express-1000K: Express-MD/AT2
Express-1000H: Amos-5/Telekom-3/Yamal-300K
Express-1000SH: Express-AM8/AT1
Express-2000: Express-AM5/AM6
The PDF is badly exporte, but it seemed like the K and H could put a second satellite on top. The K is the smallest one, the H is next, the SH is lengthened yet, and last the 2000 is the biggest one.
Since the export didn't put some letters, I'm assuming K can be stack upto three on a Proton-M with Briz-M or DM-03 US, the H can take two, and the SH can take a secondary >1200kg satellite, ll with the above stated Proton-M.
Could our Russian colleagues step in and tell us what is the correct designation of Amos-5 platform in English?
Ekspress-1000H.
Thanks Anik. This should close this debate.

If you download the PDF
Reshetnev Magazine Number 8 on page 8 they state their Express Platform.
We can expect 2 more objects to be catalogued for this Proton launch:
37952/2011-074C and 37953/2011-074D
4 objects in all: Luch-5A, Amos-5, Briz-M and Briz-M's tank
From to-day's latest data:
Object A (now presumably AMOS-5) in 35689.2 x 36057.8 km x 0.12°
Object B (now presumably Luch-5A) in 35588.1 x 35999.9 km x 4.91°
Object C (presumably Briz-M) no data yet
Object D (presumably Briz-M's tank) in 412.2 x 35863.6 km x 47.76°
USSTRATCOM has now confirmed catalog entries for both satellites:
37950 AMOS 5 2011-074A
37951 LUCH 5A 2011-074B
Could our Russian colleagues step in and tell us what is the correct designation of Amos-5 platform in English?
Ekspress-1000H.
Well, three are two different questions, what does Reshetnev call it in English when they write English copy, and what is the Russian name for it.
It would not be unprecedented for the name used by the manufacturer for a satellite in English is not a direct transliteration of the name used by them in the original language.
So Andrey, you are saying that when we see "Экспресс-1000Н" in a Russian document, the "Н" is an English H and not a Cyrillic N ?. Just trying to super-clarify here! You can see why we might be confused!
Even Reshetnev seems to get confused:
This page has both Express-1000N and Express-1000H in two consecutive sentences!
So Andrey, you are saying that when we see "Экспресс-1000Н" in a Russian document, the "Н" is an English H and not a Cyrillic N?
Jonathan, I do not know exactly, but if I see Экспресс-1000SH platform in Russian, I understand that it is Ekspress-1000SH in English, so H in Russian is H in English in this case.

That's a fair argument - Jonathan
Still no data published on 37952 / 2011-074C (Briz-M)
So ... when is Luch going to provide transmission service for the ISS Russian segment?

Some equipment for tests was delivered by Progress M-14M. All other equipment will arrive later. Beginning of transmissions will be since 2013 likely.
http://www.spaceref.com/news/viewsr.rss.html?pid=40330Preparatory to the planned launch of more Russian Luch (Altair) communications satellites, Oleg Kononenko used the FSH3 spectrum analyzer to perform another characterization test on the Lira antenna feeder, taking parameter measurements via S-band & VHF. [The Lira system is a two-way communication system between the ISS RS and TsUP Mission Control via the Russian Luch relay satellite system (when it is complete). The RS comm subsystem can receive commands directly from RGS (Russian Ground Station) through the Regul subsystem and can receive commands from the Luch satellite through Lira or Regul. Efforts are underway to rebuild the Luch relay satellite system after many years of funds-related absence. Luch-5A was successfully launched on a Proton on 12/11/2011. Luch-5B & Luch 4 are scheduled for launch this year and 2013. This should provide the RS with 45 minutes of coverage per orbit via Lira and Regul.]Maybe someone can explain the difference between Lira and Regul. There is a description of Regul further on in the notes, but its still not clear:
In the SM, FE-4 Kononenko made preparations for tomorrow's scheduled R&R (removal & replacement) of the SA-325-I transmitter unit of the Regul-OS, gathering equipment & tools. [Located in the SM, Regul-OS is a subsystem of the RSUS Radio Control & Comm System of the RS (Russian Segment) for handling two-way voice communication, digital command/program information, and telemetry transmission via Russian RGS (Groundsites). Regul is the nominal uplink channel for all Russian commands; operating at a low data rate, it is equivalent to the US S-band system. The SA-325 block to be removed tomorrow is one of three redundant transmitters, each containing a transceiver (PPA) and Digital Processor (UtsO).]
