The amateur radio packet\nbeacon operating on 145.825 MHz was activated to transmit a VHF\nsounding signal with time ticks. Due to refraction/scattering of the\nsounding signals in the exhaust plume, the shadow region would occur.\nParticipating amateur radio stations noted the time tick to register\nloss of signal and re-acquisition of the 145.825 MHZ signal as the\nfootprint caused by the plasma jet passed their geographic location.\n\nAn example of the ISS SpEx Shadowing Beacon can be found on the\nDK3WN SatBlog website at:\n\nhttp://www.dk3wn.info:\n\nRS0ISS]CQ,qAR,SR5GK-3:]ARISS - International Space Station\nDK3WN]BEACON,RS0ISS*,qAR,SR5GK-3:SpEx SHADOW 20:30:57 *DL* 02-02-2013/\nDK3WN]BEACON,RS0ISS*,qAR,SR5GK-3:SpEx SHADOW 20:30:39 *DL* 02-02-2013/\n\nAdditional details of the Shadowing Experiment are posted on the\nTSNIIMASH web site at:\n\nhttp://knts.tsniimash.ru/Shadow/en/Default.aspx\n\n[ANS thanks TSNIIMASH and Mike Rupprecht, DK3WN for the above\ninformation]\n\n\n---------------------------------------------------------------------\n\n\nCubeSats Form Asteroid Mining Exploration Fleet\n\nIn an article posted on the SpaceDaily.com website, \"Commercial\nAsteroid Hunters Announce Plans For New Robotic Exploration Fleet\",\nDeep Space Industries claims it will send a fleet of asteroid-\nprospecting spacecraft out into the solar system to hunt for\nresources to accelerate space development to benefit Earth.\n\nThese \"FireFly\" spacecraft utilize low-cost CubeSat components and\nget discounted delivery to space by ride-sharing on the launch of\nlarger communications satellites.\n\nFireFlies with a mass of about 55 lb will first be launched in 2015\non journeys of two to six months. Starting in 2016, Deep Space will\nbegin launching 70-lb DragonFlies for round-trip visits that bring\nback samples.

It is currently above 78 degrees. Once it went\nabove about 65 degrees was our last successful commanding.\n\nRecovery did not work this period. But we learned enough to be more\nsuccessful in the Fall.\n\nA \"sun-to-orbitplane-angle\" means PCsat's orbit is now over the\nday/night terminator meaning it is in full sun (no eclipses) with\nsolar power coming in on the (weaker) side panels and little if any\non the +Z face(best panel). Attitude is maintained by alignment with\nthe Earth's magnetic field. It's the best time for a recovery (no\neclipses to cause a reset), but the worst time for commanding. It is\ntoo weak to respond to the needed logon and 3 additional commands.\nThough it will be strong again as the sun angle improves (lower).\n\nThen it will have better sun on the +Z face for commanding, but then\nit will be doing Eclipses. And even though we can then command it to\nturn off unnecessary loads, it does not have enough time before the\nnext eclipse to charge up enough to survive the next eclipse.\n\nWhat we did (re)learn is a condensed command method where we can put\nall 3 PCSAT low-power commands in a single packet (using the TNC's ^V\npass character). That way, we only need a successful logon to\ncomplete the Restoration. 1) The CONNECT ACK. 2) The password\nchallenge, 3) Then the command prompt. Then we can hit it with the\nfull low-power command set and disconnect all in one packet which\ncancels the need for PCSAT to respond to each command separately.\n\nOn the FIRST day available in full sun(our best shot), I not only\ngot logged on, but completed all 3 requried functions. Then signals\nsounded so good, I got greedy and put in the another three (which\nalso improves power budget, but not as much as the first three).\nYep, I gambled and lost. It died on the last one! The next day I got\nall 3 in, and it died on the 3rdcommand due to a user packet I think.\nDays since, I have been unable to logon. Hence, end of this attempt\nperiod.\n\nIn most attempts in the past (after successful logon) we would send\none command at a time to give it a few seconds rest between each one.\nBut these 3 commands then required 3 ACKS and 3 RESPONSES in addition\nto the 3 required to get logged. Those extra 6 packets kill it,\nespecially if there was a user packet in there. Next time all we\nneed are the 3 loggon responses.\n\nAlso, next time, we will give users advance warning to QRT all\ntransmissions when we are trying to command. Each one of their\npackets robs us of power we need to complete the command. I failed\nto warn everyone this time, and so we had some interference.\n\nAs sun angle improves, You may continue to experiment with PCSAT\nduring MIDDAY passes. That is when it is strongest (in the Northern\nHemisphere), but do limit yourself to only attended operations so\nhumans can actually contact humans, or if you are doing an unattended\ntest, keep your transmissions to once every 2 minutes. That should\nlet you get one good successful packet per pass. Which is the\nmission of PCSAT.\n\nSee the downlink on http://pcsat.aprs.org\n\nThere you can see the telemetry packets (list at the bottom of page)\nright now are rarely getting above 001 meaning typically a minute or\nso of life before it gets overloaded and resets back to 000.\n\nIt is easy to visualize the relationship of the sun angle to the\norbit plane and to see how that affects power budget given that our\nbest panel (out of 5) is on the +Z face and that is magnetically\naligned to point towards magnetic South. There is NO panel on the -Z\nwhich is why PCsat is rarely usable in the Southern Hemisphere (not\nplanned, but just a result of it crashing in every eclipse).\n\nJust thought you would like to know what is going on with one of the\noldest student projects in space that is still \"semi-operational\" for\nusers.\n\n[ANS thanks Bob, Wb4APR for the above information]\n\n\n---------------------------------------------------------------------\n\n\nAMSAT-UK to provide Amateur Radio payload for ESEO satellite\n\nAMSAT-UK will be providing a 1260/145 MHz FM transponder and a 145\nMHz BPSK telemetry beacon for the European Student Earth Orbiter\n(ESEO). This is the third mission within the European Space Agency’s\nEducation Satellite Programme.\n\nNine European universities will be working with the prime contractor\nALMASpace, Italy, on the mission. Cranfield University in\nBedfordshire will be supplying a small sail that will be deployed to\ndemonstrate the de-orbiting of spacecraft at the end of the mission.\n\nThe primary purpose of the AMSAT-UK payload is to provide a downlink\ntelemetry that can be easily received by schools and colleges for\neducational outreach purposes. The data will be displayed in an\nattractive format and provide stimulation and encouragement for\nstudents to become interested in all STEM subjects in a unique way.\n\nThe target audience is primarily students at both primary and\nsecondary levels and the project includes the development of a simple\nand cheap “ground station” operating on VHF frequencies in the\nAmateur Satellite Service. This station is an omni-directional\nantenna feeding a FUNcube DonglePRO+ SDR receiver which will receive\nthe signals direct from the satellite and transfer the data to\nspecially developed graphical software running on any Windows laptop.\n\nMore information is available at\nhttp://www.uk.amsat.org/?p=12487\n\n[ANS thanks Trevor Essex, M5AKA for the above information]\n\n\n---------------------------------------------------------------------\n\n\nOSCAR-11 ANNUAL REPORT 2012\n\nThis report covers the period from 01 January 2012 to 01 January\n2013. During this time there have been no significant changes apart\nfrom the gradual drift of the on-board clock. The satellite has been\ntransmitting on a regular cycle of 10.35 days on followed by 10.35\ndays off.\n\nOSCAR-11 (AKA UoSAT-2 and UO-11) celebrated it's 28th birthday in\nspace on 01 March! It was designed, built and launched within a\nperiod of six months, using commercially available 'off the shelf'\ncomponents (COTS). Once again, congratulations to Professor Sir\nMartin Sweeting G3YJO, his team at the University of Surrey and the\ngroups of radio amateurs who also contributed to the project.\n\nGood copy has been obtained obtained from decoded telemetry frames\nand many reports have been posted on the DCARR general satellite\nstatus website, The satellite continues to be subjected to eclipses\nduring each orbit, resulting in weaker signals at those times. During\nthe summer in the UK all passes were in sunlight, however the\neclipses gradually returned during the autumn and now all evening\npasses are eclipsed and signals are significantly weaker than in the\nmorning passes.\n\nThe on-board clock gained 85 seconds during the year, which is\ncomparable with the 60 seconds gain per year when the satellite was\nlaunched. There is however a large accumulated error of 308.54204\ndays slow. This was caused mainly by the clock stopping during\neclipses, when there was also an unknown drain on the power supply.\nThe units of the least significant digit correspond approximately to\nseconds (0.86 seconds actually).\n\nAt the present time, while OSCAR-11 is operating in a predictable\nway, please DO NOT send reports or files by e-mail. However, could\nall listeners continue to enter their reports on the general\nsatellite status website. This is a very convenient and easy to use\nfacility, which shows the current status of all the amateur\nsatellites, and is of use to everyone. Reports around the expected\ntimes of switch-on and switch-off are of special interest, especially\nfor times 13:00 to 18:00 and 22:00 to 08:00 UTC, to when the\nsatellite is out-of-range in the UK .

Our contact\nwith Israel last Sunday had low audio levels, with good signals only\nnear TCA. Our contact yesterday with the Hospital for Sick Children\nwas even worse. Only one student was able to talk to Chris Hadfield\nbefore we lost the signal. The crew reports hearing the ground\nstation well. Both these contacts were with our telebridge stations,\nsome of the best out there. Also note that Chris Hadfield got on the\nIP Phone, immediately after the Hospital radio contact and answered\nall the student’s questions, using that communications medium. So,\nwhile not optimal, we were able to make both these ARISS events\nsuccessful\n\nAfter the Hospital contact, we had a full court press to revise\nuplinks and procedures to use the Ericsson radio that was recently\ninstalled in the Columbus Module instead of the D700. This was\nworked well into the crew sleep period, with the procedures ready for\nthe crew at wakeup. While we had not fully checked out the radio, we\nfelt the benefits of using this system outweighed the risks of using\nthe D700, given its recent past performance. Our contact with the\nJapan school, using the Columbus Module Ericsson radio was very\nsuccessful. We plan to use it on the contacts planned for next week.\"\n\n+ Contacts scheduled for this coming week\n\nARISS is requesting listener reports for these contacts.
