At Baikonur launch site continues preparations for the upcoming launch of a space rocket "Proton-M" with a European communications spacecraft Astra-2G / «Astra -2ZH" /.
Since the end of last week in the finishing room assembly and testing (MIC) of 92-A50 professionals Center. Khrunichev and foreign customer assembles spacecraft Astra-2G with the upper stage "Breeze-M" as part of the ascent unit (AU).
Yesterday in the MIK passed final operations with SHM - electrical inspection "assembly" apparatus and the upper stage and payload fairing installation of shutters.
In accordance with the work schedule, today began preparations for transporting AU in general assembly hall for the subsequent docking with the carrier rocket "Proton".
Telecommunications satellites Astra 2G, made Airbus Defence and Space (a division of the European Group Airbus Group) commissioned by the satellite operator SES (Lyukskemburg).
The contract for the use of the carrier rocket "Proton-M" for launching spacecraft Astra 2G concluded by International Launch Services Inc. controlling stake in ILS belongs FSUE "State Research and Production Space Center. Khrunichev ", developer and manufacturer of carrier rocket" Proton "and booster" Briz-M ".
Launching a spacecraft Astra-2G scheduled for the end of November. This will be the 400th space launch using rocket "Proton".

SES Astra 2G sat to launch on Proton Nov 28 has military Ka/X-band payload to preserve Lux govt orb slot rights, which expire in Jan.

Interesting, anyone any idea which orbital slot this refers to? If it's not somewhere between 28.0-28.5E then it could be a hint that 2G might not stay at 28.2E for long or may take it's time getting there via another slot??

On Wednesday, November 19 in the assembly and testing of 92-A50 Home General assembly carrier rocket "Proton-M" with a space head part (AU), consisting of a spacecraft "Astra-2Y» / Astra 2G and booster "Briz-M "under the nose cone.
Yesterday experts Khrunichev. And FSUE Khrunichev TsENKI - Space Center "South" performed mechanical docking missiles with SHM.
Now experts are checking the electrical components and connections within an assembled missile, test the interaction of control systems of the spacecraft, and the upper stage of the launch vehicle. For the thermal control of the spacecraft on the fairing to install a safety Insulating.
After completion of the audits will begin preparation for the removal of a space rocket (RKN) "Proton" on the technological platform for refueling refueling tanks low pressure booster.
Launching a spacecraft Astra-2G scheduled for the end of November. This will be the 400th space launch using rocket "Proton".
The contract for the use of the carrier rocket "Proton-M" for launching spacecraft Astra 2G concluded by International Launch Services Inc. controlling stake in ILS belongs FSUE "State Research and Production Space Center.

The latter seems to be the case. Main article by de Selding on Spacenews:
http://www.spacenews.com/article/mi...-placeholder-for-luxembourg’s-proposed-govsat

SES’s Astra 2G satellite, built mainly to bolster existing capacity for direct-broadcast television into Britain and Ireland, will be used to “bring into use” the Luxembourg military satellite system by occupying the future GovSat slot for at least three months. That is enough, under current International Telecommunication Union rules, to preserve a reservation.

Once it has fulfilled this task, Astra 2G will be moved to its permanent location at 28.2 or 28.5 degrees east, one of SES’s key TV-broadcast orbital neighborhoods.

So Astra 2G won't be used to take over anything at 28.2E until well into 2015.

Carrier rocket "Proton-M" spacecraft "Astra-2G" is set to launch complex
24/11/2014 15:58
Yesterday, November 23, at the Baikonur Cosmodrome State Commission has decided to roll out the launch vehicle (ILV) "Proton-M" with the upper stage "Breeze-M" and the spacecraft "Astra-2G" to the launch pad.
In accordance with the decision of the State Commission for transportation ILV "Proton-M" to the starting position began this morning at 4:30 am MSK. Currently, the carrier rocket with the spacecraft "Astra-2G" is located on the launcher. After supplying the rocket service tower and connecting communications specialists Khrunichev. Khrunichev and enterprises Roscosmos began work on schedule the first launch day.
The work plan for the next few days includes checking equipment and ground equipment ILV launch pad, fueling booster propellant components and compressed gases.
The launch is "Astra-2G" is scheduled for November 28, 2014.

The payload of Astra 2G will work X-Ku-Ka Band.

Frequencies in use...
Uplink: 7,900–8,400 MHz, 12.75–13.00 GHz, 13.00–13.09 GHz, 13.75–14.50 GHz, 17.30–17.79 GHz, 18.10–18.35 GHz, 27.85–28.45 GHz, 28.52–28.76 GHz, 28.90–31.00 GHz

Downlink: 7,250–7,750 MHz, 10.70–11.20 GHz, 11.20–11.29 GHz, 11.45–12.19 GHz, 18.85–21.20 GHz, 21.40–22.00 GHz

So 2G will only be able to cover the first 5 transponders of Band F to 12.19GHz rather than to 12.5? I knew it couldn't do Band G from 12.5-12.7 but didn't realise it would be even lower.

will be tomorrow night live launch

Probably the first 24 txp in DBS... expect the in-orbit tests to confirm..

...the tests will take place at 43,5°E

the 2a have 13 tp for now
it take 2f 5 tp ?

william-1 · Nov 25, 2014

Eutelsat 28A has 15 transponders + a few feed transponders running very low on fuel http://www.flysat.com/e28a-info.php looks destine for an inclined orbit very soon,

Eutelsat was going to replace this satellite in 2013 but due to the dispute with SES over 28.5 east they never planned it in :mad:

So will 2A & 28E last another 5 months while 2G goes on a new mission for X band transmissions ?

Eutelsat 28A will be replaced by the satellites Astra 2E, 2F and 2G, according to an agreement between Eutelsat and SES.

During tests conducted rocket "Proton-M" spacecraft "Astra-2G" at the launch complex (SC) Baikonur Cosmodrome was found in the observation complex command devices booster "Breeze-M".
State Commission decided to terminate prelaunch launch vehicle directly at the launch complex and transfer tests and inspections in the assembly building site 92A-50 to eliminate the identified faults.
The decision on the new date of launch rocket "Proton-M" spacecraft "Astra-2G" will be taken as a result of elimination of the comments in the complex command devices booster "Breeze-M".
