The latest news about the launch date and time has just been confirmed by Kosmotras. The launch date of RS-20B rocket (Dnepr) with a group of satellites (DubaiSat-2 cluster mission) from Dombarovsky missile area (Yasny Launch Base) has been established for November 21, 2013 at 07:10:11 UT. The back-up launch date is November 22, 2013 at 07:10:11 UT.
We will shortly be providing prelaunch TLEs and, in about 7/10 days, the Dashboard software that is needed to demodulate and display the telemetry information. More information about the Dashboard can found here http://funcube.org.uk/working-documents/

Hi my friends !
I'm listening the passes over western Europe of the COSMOS-2499, but there is no CW telemetry nor callsign, never, only the usual russian DOKA-B telemetry on 435.465 and 435.565 MHz . Perhaps an error ?
Then, again this morning, I watched carefully the R4UAB blog video, especially the frequency vs time, then I "replayed" the november 30th day as seen from Dmitry/R4UAB location (Ruzaevka, Republic of Mordovia, Russian Federation) with the keplerian of COSMOS-2499, the fresh good ones of NORAD : The Doppler frequency shift crossed 435.465 at about 23:15:48 on the video. At the moment, the bird was not over Russia but near the East coast of Australy. I thought, maybe the clock is not UTC but adjusted with the time zone of Mordovia (time is MSK (Moscow), UTC + 3)... So I tried 19:15:48 UTC but, yet, the bird was then not over Russia but the Pacific Ocean.
Any ideas ? The tle are the correct ones, sure, and you may verify yourself. I'm using them without problem and all the visible passes of the 2499 are received just in time, exactly, since saturday november 30th.
Have a nice week-end, 73 !

Hi Jean Pierre,
I did receive RS-47 CW Look at http://www.dk3wn.info/p/?p=52752
But this was the only time, after that I didn't receive any CW from RS-47.

Many thanks, Jan,
I was afraid that this was a coincidence, another bird in the vicinity.

Nothing heard during the 5 Nov 14 18:00 z overhead pass in Northern CaliforniaPeteWA6WOA

Thank you for the information, Pete,
I noticed that the COSMOS-2499 (and the COSMOS-2491), like was the Yubileiny-2, are transmitting ONLY when in sight of the Russian Federation. In western Europe, we have a pass East begining in about 45 mn and the two frequencies will be on. Nothing will be heard on the next one over North Antlantic.
Best 73 !

On the last pass over western Europe, orbit 2587. Both transmitters was on, 435.575 MHz with DOKA-B, 435.465 for CW telemetry. Looks like Mozhayets/RS-22.
Rhanks to Jan PE0SAT !

Hi Jean-Pierre,
Do you mean RS22 or RS47?

RS-47, undoubtedly, orbit nr 2587, with the callsign. I was watching the DOKA-b on 435.575. Then I had a look on 435.475 and went across this CW telemetry for the first time. Unfortunately, the bird was already very low above the horizon so my record is short, but after ten days watching all passes, I am very pleased. I noted, just before the COSMOS sank below horizont (directly "by ears" with a pencil :-) , but I think it's correct and I will compare with the SOUND FILE ASAP) : TCON 154 MCON 69 SMA 73 SMB 79 MRXA 26 MRXB 14 RS47 UBS 165 UAB 164 IBS ...
I no more believed it. And this is thanks to you and the post you sent, Jan.
