[amsat-bb] Re: ARISSat-1 - Battery Failure
Hi Bob all.. As far as I can see, the main reason it needs power is to allow the transmitter to stay in the OFF state during deployment and for 15 minutes after release, once it switches ON the battery can be depleted without any adverse effects. This was talked about here on -bb a few weeks back. 73 Pete 2i0VAX On Thu, Apr 14, 2011 at 5:38 PM, Bob- W7LRD w7...@comcast.net wrote: can it default to solar cells? aka AO-7 73 Bob W7LRD - Original Message - From: Clint Bradford clintbradf...@mac.com To: AMSAT BB amsat-bb@amsat.org Sent: Thursday, April 14, 2011 8:33:40 AM Subject: [amsat-bb] ARISSat-1 - Battery Failure RadioSkaf's Alexander, RA3WOK, just wrote me that they do, indeed, suspect battery failure of the ARISSat-1.

[amsat-bb] Re: AO-51 is Working Fine - My First Satellite QSO Ever!
There is something very intrinsically powerfull about this process/event. I hear it time and time again. For me it was RS12. Why does hearing your call/name or your own voice come back from a little box several hundred high, traveling at about 17,000 miles per hour have such a moving impact in our minds and lives? As I mentioned in a earlier post, the novelty never really gets old. I just recently got my mobile rig up and running and it was RS12 all over again! I accept the fact we or most of us are part of a unique group of individuals that derive profound pleasure in this activity. I have tried to explain this to normal people and they just look at me funny. At times I center my day around a computer print out. My xyl has jokingly said ,you need a intervention.

[amsat-bb] ANS-104 ANS Special Bulletin - ARISSat-1 Not Heard During Gagarin Commemoration
AMSAT NEWS SERVICE ANS-104 ANS Special Bulletin - ARISSat-1 Not Heard During Gagarin Commemoration SB SAT @ AMSAT $ANS-104.01 ARISSat-1 Not Heard During Gagarin Commemoration AMSAT News Service Bulletin 104.01 From AMSAT HQ SILVER SPRING, MD. April 14, 2011 To All RADIO AMATEURS BID: $ANS-104.01 The planned operation of ARISSat-1/RadioSkaf-V/KEDR on April 11 and April 12 from inside the International Space Station as part of the commemoration of the 50th anniversary of Yuri Gagarin's flight was not successful. No earth stations on the ground reported hearing transmissions on the ARISSat-1 downlink(145.950 MHz for FM analog/145.920 MHz for digital). The planned retransmission of the satellite's FM downlink via the Kenwood TM-D700 transceiver --currently used for ARISS contacts--was also not successful as no reports were received of signals heard on 437.550 MHz. However, a similar ARISSat-1 transmission test conducted in February was successful, with 145.950 MHz signals being successfully received by several ground stations. At this point it isn't clear to the ARISSat-1 team what went wrong with the most recent test. Unfortunately, little information has been shared by RSC-Energia concerning plans made to configure the satellite and the interface used to connect the satellite to one of the external ARISS antennas. The status of the satellite's Russian-provided silver zinc battery is also unknown. ARISSat-1 is a cooperative effort of AMSAT, RSC-Energia and NASA. AMSAT designed and built the spacecraft as a prototype of a proposed series of educational satellites which can carry student-built experiments. The ARISSat-1 prototype features a student experiment designed and built by Kursk State Technical University in Russia. A backup was also provided (without solar panels). AMSAT delivered the two units to NASA's Johnson Space Center in Houston, TX in early October. NASA has led the integration of ARISSat-1 into the ISS flight program. NASA coordinated the logistics of transporting the satellite and a backup unit, including export licensing, from Houston to Moscow. The shipment occurred in early December immediately following RSC-Energia confirmation that the appropriate import documentation had been approved. NASA also conducted the three-phase Payload Safety Review that ARISSat-1 had to pass in order to be permitted to be shipped to the ISS and deployed from the Space Station. Per protocol agreements signed by AMSAT, NASA and RSC-Energia, RSC-Energia assumed full responsibility for ARISSat-1 after NASA shipped the prime and backup units. RSC-Energia's stipulated responsibilities included integration of the Kursk experiment, providing a silver zinc battery for the spacecraft, shipment of the primary flight unit to the ISS via a Progress Cargo vehicle (which took place in January 2011) and subsequent deployment during a planned Russian EVA in February 2011. Once AMSAT shipped ARISSat-1 and the backup unit in early October, AMSAT was no longer directly involved with management and operation of the satellite. AMSAT agreed to send a representative to Moscow (Lou McFadin, W5DID) in order to assist with testing and final checkout of the satellite once it arrived from the US. Lou was accompanied by NASA's Mark Steiner, K3MS and the requests for visas and access the RSC-Energia facilities was coordinated by NASA. Due to visa limitations (Russia does not allow changes to visas once individuals are in Russia), the window for Lou's and Mark's time in Moscow could not be changed once it became apparent that the shipment was being held by Russian customs and wouldn't be released until after the expiration of visas. During the time that Lou and Mark were in Moscow, testing procedures were drafted and agreed to by RSC-Energia's principal investigator for ARISSat-1 (Sergey Samburov, RV3DR) as a signed protocol to assist the Russian engineers with testing and checkout without the presence of AMSAT. Lou and Mark departed Moscow on 22 DEC 10 for the US and the satellite with the backup unit were subsequently released from Russian customs and delivered to RSC-Energia on 28 DEC 10 following submission of appropriate documentation by RSC-Energia. In addition to the missed opportunity for AMSAT and NASA to participate in the checkout in Moscow, the delayed release from Russian Customs also meant that the satellite arrived in RSC-Energia just as they were commencing a 10-day total holiday shutdown from 1-10 JAN 11. In order to make launch of the Progress 41P cargo vehicle to the ISS in January, the satellite had to be flown to the Baikonour Cosmodrome on 11 JAN 11, the day after RSC-Energia personnel returned from their holiday. Sergey Samburov, RV3DR spent a period of time during the holiday period conducting a checkout of the satellite, but it is still unclear whether the documentation provided by Lou McFadin and Mark Steiner and agreed to as a

[amsat-bb] XE3DX Grid Expedition April 17-30th
David XE3DX recently posted that he will be operating from EK08, EK09, EK18 and EK19 from April 17th to the 30th. These are grids that you don't hear very often so if you are chasing grids, be on the lookout and please give David some room. This morning's AO-51 pass at 1050z was a little exciting. XE1SOV showed up from EK18, one of the grids that David will operate from and a new one for me. David was also on the pass and worked a few stations. After the pass, David emailed me with a request that we should use phonetics when working him and other XE's. He asked me to confirm some of the callsigns he heard/worked where phonetics were not used. This is not an issue for debate and please do not respond one way or the other. I am simply passing on his request. Act on it as you see fit. David uses LOTW, so if you make a contact you'll be able to get confirmation without sending for a card. If he doesn't get your call right, there will be no match in LOTW. As an aside, the US postal rate to Mexico (and Canada) goes to $.80 for 1 oz. effective April 17th. All other countries remain at $.98 for 1 oz. 73, John K8YSE ___ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?

[amsat-bb] Re: ARISSat-1 - Battery Failure
Dear Friends, There has been a great deal of speculation on the amsat-bb about the Russian battery on ARISSat-1 having failed. Be aware that this is nothing other than idle speculation. There has been no information from RSC-Energia to support this. I believe the mis-information comes from a report on the ARISSat-1 power system that was written by me and sent to RSC-Energia. One of the sections included a prediction of the battery life in orbit. The 825M3 is a Russian space suit battery and its life was not specified or characterized for operation of a satellite. The most recent AMSAT Journal includes an article that covers this material. The article in the AMSAT journal predicts that the 825M3 battery should last for about 2 months in orbit. That means that if the satellite was deployed in February as originally planned, it might be too weak to run the satellite reliably by the time the Yuri celebration commenced on April 12th. This fact was stated on the (Russian) Roscosmos web site but is being misinterpreted as the battery is weak. For the record, the battery in ARISSat-1 was a brand new 825M3 space suit battery and was charged on the ISS prior to the February test. After charging, the battery can run ARISSat-1 for at least 100 hours so it should have had more than enough remaining charge to operate through the Yuri Gagarin event. It is of course possible that the battery did indeed fail but any information propagated on amsat-bb to that effect at this time is not based on facts. AMSAT is working with RSC-Energia and NASA to identify the actual reason that the satellite was not heard. 73, Tony AA2TX ___ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author.

[amsat-bb] FN01 tomorrow (4/15)
Weather- and Murphy-permitting, I will be in PA State Game Lands 95 tomorrow (FN01bb) and working most of the daytime passes, hopefully starting with SO-50 at 1345 and going till AO-51 at 2120. Hope to work you then. I'll post other info on my QRZ.com. 73 Doc KT3L ___ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?

[amsat-bb] ARRIsat-1 - No Show
It really does not instill much confidence in partnering with RSC-Energia for any future satellites. I will withhold judgement of individuals involved till we learn more. I certainly am not in favor of spending Amsat funds on such a venture, again. But then I no longer have a voice in the matter as I have let my membership in Amsat lapse. That was totally a financial decision - as a senior retired on social security, I have to chose what I spend money for. I could continue a couple memberships that provide a senior/retired rate. That also means I am retired as a field op. 73, Ed - KL7UW, WD2XSH/45 == BP40IQ 500 KHz - 10-GHz www.kl7uw.com EME: 144-1.4kw, 432-100w, 1296-testing*, 3400-winter?

I hope AMSAT will be able to identify the actual technical reason that the satellite was not heard. To be honest with you the actual situation of a unknow technical reason for ARISSsat-1 is spiritually similar to when someone forgot to remove the famous red cap over a valve of AO40 before to fly and once again we are all concerned for the future !

[amsat-bb] Joe Pollyanna Fitzgerald on ARISSat-1
The ARISSat-1 project can chalk up many successes, here is my list so far: AMSAT has: Built and launched a spacecraft which has sent signals back to earth Grown up significantly in our project management capabilities, now bearing fruit as AMSAT-Fox is developed Developed a telemetry scheme that gives us several dB advantage over anything else previously flown on an amateur or small university spacecraft Gown in our understanding of and implementation of ITAR compliance Learned a fair amount about extracting the most power out of solar panels and putting it to work or storage And on a personal level, I have: Learned a lot about project management - Learned a lot about BPSK demodulation and channel codecs Been privileged to work with a lot of smart people -Joe KM1P ___ Sent via AMSAT-BB@amsat.org.
