Photos Dec. 25, 2008 - Triple GLONASS on Proton M / DM-2

The launch time is:
16:43:00 Baikonur
13:43:00 MST
10:43:00 UTC
5:43:00 a.m. EST





Khrunichev’s Proton Block DM launch vehicle is scheduled to place into orbit three new GLONASS satellites on 25 December from the Baikonur Cosmodrome in Kazakhstan.

The first of the three satellites has already arrived at the space center, with the remaining two scheduled to arrive by early December, according to the Russian space agency. This will be the second launch of the year with a GLONASS mission, following the successful Proton launch of three GLONASS satellites on 25 September.

GLONASS (Global Navigation Satellite System) is Russia's equivalent to the Global Positioning System (GPS) created by the United States. GLONASS is used for military and civilian purposes. The system is intended to provide continuous navigation coverage allowing an unlimited number of domestic and foreign users at sea, in the air and on land to determine precise coordinates, velocity and time.

To cover the entire Russian Federation landscape, GLONASS requires 18 operational satellites. At present, 17 satellites are operational. GLONASS would require 24 operational satellites in order to provide services worlwide.

According to Roscosmos chief Anatoly Perminov, there will be 30 GLONASS satellites in orbit by 2011.

The three new Uragan-M satellites are expected to replenish the plane 1, which is currently most decayed of all.



The Uragan-M spacecraft are 3-axis stabilized, nadir pointing with dual solar arrays. The payload consists of L-Band navigation signals in 25 channels separated by 0.5625 MHz intervals in 2 frequency bands: 1602.5625 - 1615.5 MHz and 1240 - 1260 MHz. EIRP 25 to 27 dBW. Right hand circular polarized. On-board cesium clocks provide time accuracy to 1000 nanoseconds. A a civil reference signal on L2 frequency is to be added after the completion of flight testing of Glonass-M in 2004 to substantially increase the accuracy of navigation relaying on civil signals.

01-12-2008 The pre-launch works on the three GLONASS-M satellites are proceesing on schedule
Pre-launch preparation works for the GLONASS satellites are continuing on Baikonur Cosmodrome. The first of the three spacecrafts has been processed.
At the moment, the Roscosmos enterprises teams are working on the second one.
Arrival of the third satellite at the Cosmodrome is expected in the soonest time. The launch will be commenced in the end of December.

The works on three GLONASS-M satellites are carried out in the assembly building 92-50 at Baikonur.

Yesterday, on Dec. 3 the third of the satellites was delivered to Baikonur and teams of the OAO "Information Satellite Systems" began preparing it for the launch. Today the spacecraft has been coupled to the tank pre-filled with propellant components. The works are continuing on schedule.



Meanwhile, assembly of the Proton-M rocket which carry the three GLONASS satellites to orbit is being done in the hall 111 of the assembly building 92-50. The stages 2 and 3 assembled together and the stage 1 are loaded on the cradles for coupling and performing of the post-assembly tests.

09-12-2008 Assembly of the Three Glonass-M Satellites is Over

Baikonur Space Port: prelaunch activities with Proton-M rocket and three Glonass-M satellites continue at Baikonur.
The third spacecraft has been assembled; it underwent electrical tests today.
In addition, upper segment is being assembled. The first satellite has been already installed on the separation unit.
Currently, 17 satellites operate in the GLONASS constellation.

15-12-2008 Plelaunch Processing of the Glonass Satellites

DM upper stage had been delivered to the integration and test facility (site 92-50) after propellant filling. This was the first operation to be carried up in this facility, thus the expert groups and QA were very attentive and accurate.

Satellites assembly was installed on the upper stage. The operation was completed by Khrunichev plant and Reshetnev Informational Satellite Systems company specialists in line with the schedule. The prepared upper stage has been fitted on with the triplet of spacecrafts. Prelaunch activities with the upper segment continue.





Later on, the DM upper stage assembled together with the three GLONASS-M satellites, has been encapsulated in the payload fairing. After planned checks, the payload stack will be mounted on the Proton-M launch vehicle. The launch will commence on December 25 at 13:43 Moscow Standard Time.

Honestly, I had to google for the clue, because in Orthodox tradition they weren't some kings, just elderly wizards. And BTW, the Orthodox Christmas is Dec 25 by the Julian Calendar, which falls to Gregorian January 7. Thus you can be sure everyone on the Proton LC will still stay sober when the time comes to kick the mission off...

And yeah, the first post-Christmas planned launch will be Coronas-Photon sat on January 29.

Photos Streaming video link

The launch day activities proceed according to the schedule. If you want to watch the launch live, the following link will get you there (although with Russian narration):

Start watching 10 to 15 minutes before the launch time (see the top of the thread).

UPD: The straight link to watch the streaming video is:

Live translation begins

There's a lift-off

End of the live translation. The rocket was hardly seen behind the rolling stock indices... And who gave that gal the idea to say that "only 4 sats are to reinforce the GLONASS constellation" when the present launch is still under way?


-----Post Added-----


According to Roscosmos information, everything is looking fine so far:

At 10:53 UTC: the Orbital Composite was put to the sub-orbital trajectory;
The planned time for the 3 spacecraft separation is 14:15 UTC

Mission successful!

The three GLONASS-M satellites were successfully put into the target orbit and separated from the Block-DM upper stage. That was the final of 27 Russian space launches in the year 2008. The spacecrafts have been given designations Melchior-2447, Gaspar-2448 and Baltasar-2449. :angel:
