Hi all,
The recent events are dramatically. Our two ground stations are almost inoperable.
A few days ago however, a hard-reset of the satellite had occurred, which brought the satellite back into the following vicious circle: Once the heater is being switched on, the battery power drops drastically, which causes another hard-reset. This goes on and on. The only chance to recover the satellite is to avoid the activation of the heater. This can be done by adjusting threshold values.
Since these values are reset after each hard-reset, we would need to send them again and again, until the satellite is in a stable condition (batteries charging), where no reset occurs.
Thus, if you would like to support this recovery phase and have the right equipment to do so, please upload the following DTMF tones to COMPASS-1 (simply from loudspeaker via microphone)
THRESHOLD ADJUSTMENT (to do after every hard reset)
****14#200# heater off to -55 degr THIS IS THE VERY IMPORTANT COMMAND
****13#200# heater on to -55 degr ****16#170# critical batt threshold to 3.3V ****15#255# low batt threshold to max -> charge batteries
The commands consist of 4 stars, two numbers, a hash, 3 numbers, and a hash.
If COMPASS receive this sequence successfully you can hear a short confirmation beep.

Mike,
I have just sent the tone sequences to compass and received a very short beep tone immediately after each command on the downlink. The tone has a slight change of pitch for its duration. The equipment used was a TS-2000 with the tones in memory and the tone duration set to "SLOW" (100ms tone, 100ms mute). Compass pass at 2102 UT and max el 54 deg.

Hi Alan,
great - that sounds very good :-)
This is a good sign, that the batteries are not dead and the voltage is around 3.2 volt. So we can only wait to the next passes. Maybe the battery voltage is increased and the beacon on. Could you please continue trying to send the codes?
I think we have only a good chance if COMPASS is in full sunlight.
Thanks again and best 73, Mike DK3WN

Hi all,
Now we received 2 successfully contacts with COMPASS from Alan (ZL2BX) and Sion (9W2QC). On both passes was COMPASS in full sunlight.
The most important commando is ****#14#200# to switch the heater off.
Thank you so much for your effort and time. And please, continue to trying and help us to recover COMPASS.
Again, thank you very much for your help.

Hi Mike,
Unfortunately I was out for the second sunlit pass over ZL this morning so was unable to send commands on that pass. I have just had two Compass passes here in eclipse. No response to the commands so will try again in the morning when there are three sunlit passes here although two are quite low (9 and 8 degrees) and one good one at 84 deg.

I had a pass about 15 min ago where my satellite program (Predict) showed COMPASS just coming out of eclipse. I sent the heater sequence (****14#200#; no # after the *'s) a few times by hand (DTMF keypad) until the calculated LOS. No beep was heard, but I haven't calibrated my receive side frequency to this satellite, so I might have missed it.
Is the DTMF timing important?

Hi folks:
If you are interested in seeing video of our successful ARISS contact today, please check out these links:
http://nasa.id.ucsb.edu/ This was recorded by the University of California Santa Barbara
http://sbarc.camstreams.com/ This was recorded by WB9KMO and is playing constantly on a continuous loop.
We had a great contact today and even had a chance to do an AO51 demo right before the ISS pass. I will be updating my web page (www.n6kth.com) soon to include links to our media coverage.
