SB SAT @ AMSAT $ANS-331.01 Longer Eclipse Periods Affecting AO-51 Operation
AMSAT News Service Bulletin 331.01
From AMSAT HQ SILVER SPRING, MD.
November 27, 2011 To All RADIO AMATEURS BID: $ANS-331.01
AO-51 Command Stations report that the seven year old spacecraft is now shutting down its transmitter after losing sunlight on its solar panels during eclipse periods. Two of the six battery cells are now dead. Since July 31, 2010 AO-51 has maintained continuous and stable operations due to careful tuning of its power settings.
The AO-51 Operations Team reported on November 25 that the on-board computer (IHU) crashed between 1815 and 1945Z due to low voltage. This happened after a few days of intermittent and unpredictable operation.
AO-51 Control Operators Mark Hammond, N8MH and Drew Glasbrenner, KO4MA reset the satellite and started the repeater back up around ~2030Z. Satellite operation was set to the following:
Uplink: 145.880, no PL tone required Downlink: 435.150 at about 300 milliwatts
Drew reported that telemetry data showed the battery voltage was low, around 4.9v, with cell 1 less than 1 volt. The impending third cell failure will likely end continuing operations, particularly if it fails shorted as the others have. At present there remains little margin as the operations team has observed the transmitters cutting off around 4.7 to 4.6 volts prior to the last reset, in eclipse.
Please submit your AO-51 reports to the OSCAR Status Web Page: http://oscar.dcarr.org. The command stations monitor this for changes in the operation. While worldwide participation is good, more reports from US operators are appreciated.
Eclipse periods, which are expected to reach 30 minutes by the end of 2011, are causing AO-51 to shut itself OFF due to low voltage.
Please support AMSAT-NA and the other AMSAT groups around the world, and help us get new satellites into orbit. Projects like Fox, FunCube, P3E, and Kiwisat need your financial support to keep our amateur sat- ellite fleet flying.

SB SAT @ AMSAT $ANS-331.02 Latest AMSAT Project Fox Information Posted
AMSAT News Service Bulletin 331.02
From AMSAT HQ SILVER SPRING, MD.
November 27, 2011 To All RADIO AMATEURS BID: $ANS-331.02
AMSAT-NA's next generation of satellites, Fox-1 and Fox-2 are under development by the Engineering Team.
Fox-1 will replace the aging AO-51 satellite which has performed as the most popular EasySat, attracting new satellite operators since it can be worked with simple equipment. However, after more than 7 years of service, AO-51 is starting to show its age and needs an affordable replacement.
Why two satellites? The original Fox Engineering Team Study was for a baseline satellite, with several options for enhancements. At that time, AO-51 was functioning well, with no indication that its life- time would be short enough to impact the Fox Project. With the im- pending loss of AO-51, it was decided to break the Fox Project up into a quickly deployable baseline FM satellite, Fox-1, and a second more flexible satellite, Fox-2.
Fox-2 will benefit from the development work of the baseline Fox-1, with the additional time being applied to developing its more sophis- ticated power and Software Defined Transponder (SDX) communications systems.
The Powerpoint presentations on AMSAT's Fox web site provide a good view of the technical progress: http://www.amsat.org/amsat-new/fox/
Project milestones completed this year:
+ Fox-1 project defined - July 2011 + Concept of Operations (ConOps) - September 2011 + System Requirements Spec (SRS) - October 2011 + Experiment Payload Specification - November 2011 + NASA ELaNa Proposal Submitted - November 2011
Preliminary milestones for 2012 and 2013 are:
+ Baselined Project Plan - January 2012 + Preliminary Design Review (PDR) - March 2012 + Engineering prototype - July 2012 + Critical Design Review (CDR) - August 2012 + Flight model ready for test - November 2012 + Launch Readiness Review - January 2013 + Launch Target - 2nd half of 2013
Also available for download from the AMSAT Project Fox web page are the Powerpoint presentations by members of the AMSAT Engineering Team at the 2011 AMSAT Space Symposium in San Jose:

SB SAT @ AMSAT $ANS-331.04 This Week 50 Years Ago: OSCAR 1 Announcement for December 1, 1961
AMSAT News Service Bulletin 331.04
From AMSAT HQ SILVER SPRING, MD.
November 27, 2011 To All RADIO AMATEURS BID: $ANS-331.04
The AMSAT News Service is re-running the Project OSCAR Newsletters to commemorate the 50th anniversary of OSCAR 1. During the November/ December 2011 time frame you will be able to share the excitement of the launch campaign that started it all 50 years ago.
The Newsletters were hand-typed back in 1961. Thanks to Don Ferguson, KD6IRE for scanning the original documents announcing OSCAR 1.
----- <Begin Commemorative Message>
O S C A R N E W S L E T T E R
December 1, 1961
Good News! The following is quoted from the Department of Defense News Release dated November 15, 1961:
AIR FORCE TO ORBIT SMALL SATELLITE FOR "HAM" OPERATORS' USE
"The Air Force is planning to boost into orbit a small amateur radio satellite so that "ham" operators around the world can contribute to the world's knowledge on the development and operation of space com- munications systems."
"Known as Project OSCAR - Orbiting Satellite Carrying Amateur Radio - the program is the result of extensive thought and planning on the part of several California amateur operators. They have formed the OSCAR Association to follow through on the project.
"The Air Force Space Systems Division in Los Angeles has agreed to orbit the OSCAR satellite on a space available basis on board a DISCOVERER satellite which will be launched from Vandenberg AFB next month.
"The OSCAR satellite will weigh approximately ten pounds and will be lifted into orbit on the external aft portion of the AGENA Satellite. Sometime after the AGENA has attained orbit the OSCAR satellite will separate from the mother vehicle. Antennae will extend and the trans- mitter will commence operation. The OSCAR satellite will contain its own battery power system and is anticipated to have a 30-day life in orbit. "The OSCAR satellite is designed to investigate radio propaga- tion phenomena in the two meter (144-146) portion of the radio freq- uency spectrum."
Simultaneously, a letter from Dr. J. V. Charyk, Under Secretary of the Air Force to the American Radio Relay League, says (in part):
"I am pleased to advise that the Air Force will undertake to place into orbit an Oscar package.....Our Space Systems Division has been instructed to accomplish the Oscar package launching at the earliest feasible date (italics ours) on a non-interference basis to the per- formance or mission of the launch carrier vehic1e..... Please be assured of the complete cooperation by the Air Force toward success- ful accomplishment of this amateur experiment."
THIS MEANS THAT THE LAUNCH INTO SPACE OF OSCAR I, THE WORLD'S FIRST AMATEUR RADIO SATELLITE IS IMINENT -- PROBABLY WELL WITHIN THE MONTH! ACTUAL LAUNCH DATE CANNOT BE YET RELEASED FOR SECURITY REASONS. LIS- TEN TO THE VOICE OF AMERICA BROADCASTS AND THE OFFICIAL ARRL BROAD- CAST FROM WIAW FOR LAUNCH DATE! ALSO WATCH YOUR LOCAL NEWSPAPER FOR LAUNCH INFORMATION!
RECENT "UP" AND "AP" OSCAR NEWS DESPATCHES HAVE BEEN FEATURED IN MAJOR NEWSPAPERS, AND IN ADDITION, W6SAI AND K6LFH WERE INTERVIEW- ED BY VOICE OF AMERICA ON THE NOVEMBER 27TH AMATEUR RADIO PROGRAM WHICH FEATURED THE OSCAR STORY. YOUR COOPERATION IN THIS IMPORTANT, WORLD-WIDE AMATEUR SPACE EXPERIMENT IS URGENTLY REQUIRED. SEE RE- CENT ISSUES OF QST AND CQ MAGAZINES FOR ARTICLES ON RECEPTION AND TRACKING OF THE OSCAR 145 MC RADIO BEACON. AS THE BEACON HAS NO RECEPTION PACILITIES, QQ NQT MAKE CALLS TO THE BEACON. KEEP YOUR TRANSMITTER CLEAR OF 145 MC! OSCAR I WILL BE IN POLAR ORBIT, THUS PASSING OVER EACH POINT ON EARTH APPROXIMATELY FOUR TIMES PER DAY ON NORTH-TO-SOUTH AND SOUTH-TO-NORTH ORBITS.
THE TIME IS NOW! ARE YOU READY?
NOW THAT WE HAVE RECEIVED ALL NECESSARY PERMISSION AND ASSISTANCE, OSCAR 1 WILL BE ON ITS OWN WHEN IT IS EJECTED FROM THE PARENT VE- HICLE. THE OSCAR ASSOCIATION AND THE U. S. AIR FORCE HAVE AT THIS POINT DONE ALL THEY CAN DO TO MAKE THE EXPERIMENT A SUCCESSFUL ONE. THE RESULTS OF THIS EXPERIMENT WILL DEPEND UPON YOU - THE RADIO AMA- TEUR. YOU MUST CARRY ON FROM THIS POINT! YOUR COOPERATION IN THIS NON-COMMERCIAL, NON-MILITARY SPACE EFFORT WILL BE IN THE BEST TRA- DITIONS OF AMATEUR RADIO!
GOOD LUCK!
A11 reception reports of Oscar I should be directed to: Oscar Association, P. O. Box ---, Sunnyvale, California, USA. A11 correct reports will receive a special OSCAR I QSL card, veri- fying reception of the world's first amateur radio satellite.

SB SAT @ AMSAT $ANS-331.06 Next Proposal Cycle for US Based ARISS School Contacts Opens
AMSAT News Service Bulletin 331.06
From AMSAT HQ SILVER SPRING, MD.
November 27, 2011 To All RADIO AMATEURS BID: $ANS-331.06
NASA is now accepting proposals from U.S. schools, museums, science centers and community youth organizations to host an Amateur Radio on the International Space Station, or ARISS, contact between July 15, 2012, and Jan. 15, 2013. To maximize these radio contact opportunities, NASA is looking for organizations that will draw large numbers of participants and integrate the contact into a well- developed education plan. Proposals are due Jan. 30, 2012.
Using amateur radio, students can ask astronauts questions about life in space and other space-related topics. Students fully engage in the ARISS contact by helping set up an amateur radio ground sta- tion at the school and then using that station to talk directly with a crew member on the International Space Station for approximately 10 minutes. The technology is easier to acquire than ever before. ARISS has a network of mentors to help you obtain the technology required to host this once in a lifetime opportunity for your students.
Interested parties should contact Teaching From Space, a NASA Educa- tion office, to obtain complete information including how the tech- nology works, what is expected of the host organization and how to obtain the proposal/application form by sending an email to J [email protected] or by calling 281-244-1919.

In addition to regular membership, AMSAT offers membership in the President's Club. Members of the President's Club, as sus- taining donors to AMSAT Project Funds, will be eligible to re- ceive additional benefits. Application forms are available from the AMSAT Office. And, with that, please keep in mind the ham who learned many words in mathematics and geometry have their root in ancient languages. A contemporary of Pythagoras was watching a parrot playing with some twigs. Although birds often play with twigs, leaves and branches, this parrot, to the mathe- matician's amazement, actually arranged the pieces of wood into a pattern with multiple sides. Then, unfortunately, the bird keeled over, dead. The mathematician was so moved that he named the shape, "Dead parrot." Although - of course - this is why, to this day, we call that shape a polygon.
