It is with a heavy heart I report that AO-51 has ceased transmission and is not responding to commands. The last telemetry data indicated that the third of six batteries was approaching failure to short, and observations indicate the voltage from three cells is insufficient to power the UHF transmitters. The IHU may continue to be operative. Initial tests with the S band transmitter were also not positive, although more attempts are in order. We have tried leaving the satellite in an expected state where if voltages climb high enough, the 435.150 transmitter may possibly be heard.
The command team will regularly attempt communications with the satellite over the coming months (and years). There is always the possibility that a cell will open and we could once again talk to our friend while illuminated. Thanks to all who helped fund, design, build, launch, command, and operate AO-51. It's 7 year mission has been extraordinary. Please support AMSAT's Fox-1 project, and other AMSAT projects worldwide with your time and money.

Hi,
Thanks for reading.
Is there an expected state when the voltage is high enough regarding AO-51.
The reason I ask, is to listen and see if there is some life in the satellite when the voltage becomes high enough when there is full exposure after the coming eclipse periode.
73 Jan PE0SAT
It's not so much a problem of not enough illumination, but more that we are running on 3 or 3.5 cells, and we need ~4 to make the transmitters work. There may be some points during the orbit when the V gets high enough for the transmitter to come on at low power, but that is conjecture only. We don't know when or really even if that will happen.
If a cell opens up in the future, the IHU will immediately crash upon eclipse, and the battery voltage -may- rise to whatever the panels can provide. If this happens we may be able to restart the IHU and get a transmitter running, but it will only last until the next eclipse.
73, Drew KO4MA
PS. I note that the UK-DMC1 satellite was retired today after 8 years in orbit due to battery condition. We are almost as good as the mega-dollar pros! http://blog.sstl.co.uk/archives/394-UK-DMC-1-to-take-well-earned-retirement....

Drew,
I first want to wish you and your growing family the very best for the Holidays!
AO-51, has been one of my best satellite recruiting tools and I will certainly miss her, however she gave us many wonderful years of faithful service, good bye dear friend.
Drew, it is also important to note that you and the control team, managed AO-51 in a manner that I believe extended her life, thank you.
As you noted we all must continue to support AMSAT's Fox-1 project, and other AMSAT projects I believe thru Amateur Satellites we have found a potential path to excite the children today and continue the STEM initiative.
73's Pete WB2OQQ www.massapequanyweather.com
Yes, thanks for all of the great work with AO51. I do have a question, though. Please don't think that I am being critical of AO51, the design team, or the command team, because I am not. That have all done a great job. What I am curious about is this: AO27 has been going for 18 years and is still doing fine. AO51 made it around 6 years. What is the main difference between the 2 satellites that might explain the 300% difference in operational life?

It's a fair question.
AO-27 runs a 500mw transmitter for around 8-9 minutes, while illuminated, per each 100 minute orbit.
AO-51 for most of it's life, ran -two- transmitters at 300mw to over 1w each, worldwide, and most of the time through eclipse.
That should make the difference more apparent.

is still doing fine. AO51 made it around 6 years. What is the main difference between the 2 satellites that might explain the 300% difference in operational life?
Even more generally: what are the most frequent death causes for amateur satellites?
From reading the history of past Oscars, I get the impression that most sat
losses are due to dead or shorted batteries, plus dead electronics (supposedly due to radiation) and malfunctioning engines (on satellites that have them, that is). Is it really the case?

Batteries, batteries, batteries, and occasionally a bad component or piece of space junk.
Would now be a good time to mention that Fox-1 is designed to operate while illuminated, even after a battery failure?
73, Drew KO4MA
Actually, I think AO-51 was launched at the end of June 2004. That makes it about 7.5 years...but who's counting ;)
We essentially got "a free, bonus overtime" from July 2010 until now. We thought it was about gone back then...check your logs and see just how many QSOs you made on AO-51 from the end of July 2010 until the end of November 2011 (and then check how many overall during the 7.5 year). I suspect the cumulative number of contacts would be staggering.
My thought is how much data I downloaded from that old bird!
Losing a bird you've had the privilege of commanding is like losing a best friend...
Looking forward to Fox-1(and siblings...) !!

Hi Mark!

We thought it was about gone back then...check your logs and see just how many QSOs you made on AO-51 from the end of July 2010 until the end of November 2011 (and then check how many overall during the 7.5 year). I suspect the cumulative number of contacts would be staggering.
Since you asked..... :-)
With all my personal calls, I have logged a total of 10931 satellite QSOs. Of those, 4891 (44.7%) were on AO-51's different configurations, made from locations across the continental USA as well as from Canada and Mexico. Since July 2010, I have logged 2233 satellite QSOs, with 574 of those (25.7%) on AO-51. My last AO-51 QSOs were logged on 13 November.
As others have said, AO-51 was the satellite that brought me into this part of our hobby. I had been a member of AMSAT for a few years before then, worked a couple of stations on SO-35 in 2000 and a QSO on UO-14 in 2003, and even pitched in a little $$$ to help toward the AO-51 launch fundraising campaign in 2004. Once I started on AO-51, I tried SO-50 and AO-27, the ISS cross-band repeater when it was active, and then on to SSB and CW via satellite. And it's still fun....... :-)
Looking forward to Fox-1(and siblings...) !!
Yes! As we continue using other satellites that remain operational, here's hoping we are able to use the Fox satellites and those from other AMSAT groups in the near future.
73!

Yes, I think thanks are in order for you and the operations team who provided us with many years of enjoyment on countless AO-51 QSO's. Job well done from start to finish. RIP little satellite. May your solar panels always been shone on ;) Look up and see what your grand-daddy, AO-07, has done and maybe you can draw the inspiration to come back to life in a decade or so.

Dear Friends, It is really a sad news. Bidding a farewell to AO-51 with a very heavy heart.
Looking at the success, we all at Upagrah Amateur Radio Club VU2URC at ISRO Satellite Centre and AMSAT-India express our heartfelt and sincere thanks, appreciations and compliments to the entire AO-51 (ECHO) team.
The AO-51 mission is accomplished with a great and complete success. AO-51 was truly one of the best amateur radio satellites. It was a very favorite for many of our VU hams for its strong signals and ease of operations. we really enjoyed on being AO 51 very long time and it is really hard to bid a farewell to this wonderful bird.
'Thank you AO-51 for your great and fruitful services to the World of Amateur Radio'.
Our congratulations to the entire control & command team for their extra-ordinary efforts and incredible technical competence exhibited in keeping up this 'Cute Little Boy' healthy & alive in orbit for such a long period of time.
We take this opportunity to thank each & every one associated with this great project and wish AMSAT-NA all the success in their future endeavors. We at Upagrah Amateur Radio Club VU2URC at ISRO Satellite Centre and AMSAT-India assure all the possible and best help for the common cause of Amateur Radio.
73 es good wishes for a 'Happy Christmas & New Year'.

AO-51 will be remebered to me as I am sure some of those great old birds were for the ones that have been around long enough... I hope that one day I will be able to talk on something of that caliber from the stories I hear. Anyway I always enjoyed every contact and sure miss stayin up all night to catch the early bird!
