Your mileage may vary.\nWith an Arrow, 5 W has been used successfully to make contacts.\n\nPolarity is important. The satellite antennas are linear. So, if you\nare using linearly polarized antennas, you will need to adjust\nthroughout the pass. Full duplex operation facilitates these\nadjustments while transmitting and is highly recommended.\n\nThe downlink is very strong and should be heard well with almost any\nantenna.\n\nDownlink audio is 5 kHz deviation, as expected. Many will perceive\nthat the audio is \"low.\" This is an effect of the filtering below 300\nHz, which provides for the DUV telemetry, coupled with any noise on\nthe uplink signal resulting from lack of full quieting or being off\nfrequency. That makes for less fidelity than a typical receiver in\nterms of audio frequencies passed.\n\nTransmit (downlink) frequency varies with temperature. Due to the\nwide range of temperatures we are seeing in the eclipse cycle, the\ntransmitter can be anywhere from around 500 Hz low at 10°C to near 2\nkHz low at 40°C.\n\nReceive frequency has been generally agreed to be about 435.170 MHz,\nalthough the AFC makes that hard to pin down and also helps with the\nuplinks that are off frequency.\n\nProbably the most notable observations about AO-85 are an apparent\nlack of sensitivity and difficulty in turning on the repeater with\nthe 67 Hz CTCSS when it is not yet activated, or holding it on by the\npresence of the CTCSS. We have determined a probable cause for the\nsensitivity issue and while that can't be fixed on AO-85 we are\ntaking steps to prevent similar issues on the rest of the Fox-1\nCubeSats. The tone detection threshold along with the receive\nsensitivity issue makes it hard to bring up the repeater. This is\nbeing addressed by adjusting the values for a valid tone detection in\nthe other Fox-1 CubeSats now that we have on orbit information about\ntemperatures and power budget. Full details will be in the Nov/Dec\nAMSAT Journal.\n\nIt is important to remember that science is the reason behind the\nFox-1 satellites. Not only does science help with the launch cost, it\nprovides a great amount of educational value both from the science\npayload and in amateur radio itself. The data-under-voice (DUV)\ntelemetry is an excellent way to provide the science without\nsacrificing the use of the satellite for communications, which would\nbe the case if higher speed downlinks were needed. DUV provides\nconstant science as long as the repeater is in use, which in turn\nprovides more downlink data for the science - a mutually beneficial\ncombination.\n\nFox-1A is AMSAT-NA's first CubeSat. Many new techniques are\nincorporated and lessons will be learned, as with any new \"product.\"\nThe Fox-1 Project is a series of CubeSats. A total of five will be\nbuilt and flown. Launches are scheduled for three more, and a new\nNASA CubeSat Launch Initiative proposal will be submitted for the\nfifth. We will incorporate changes from what we learn in each launch,\nto the extent possible, in subsequent Fox-1 CubeSats.\n\nOf the four NASA sponsored CubeSats on the ELaNa XII launch October\n8, we are sad to report that ARC1 was never heard from and BisonSat\nwas lost after a few weeks of operation. AMSAT extends our deepest\nsympathy to the people who worked so hard on these projects. To our\nmembers, we want to say that the Fox Team is very proud and pleased\nthat our first CubeSat is very successful and hopefully will be for\nsome time.\n\n\n[ANS thanks AMSAT's Vice President of Engineering, Jerry Buxton, N0JY\nfor the above information]\n\n\n---------------------------------------------------------------------\n\n\nThe Second Birthday of FUNcube-1 (AO-73)\n\n\nThe FUNcube-1 Ops Team reports:\nFUNcube-1 was launched into space two years ago on November 21st 2013.\n\nWe are delighted to be able to report that more than 900 stations, including\nmany schools around the world, have received the telemetry from the \nspacecraft\nsince launch. Our Data Warehouse is storing more than 750 MB of data from\nalmost 1 million data packets. We are very grateful to everyone who has been\ncontributing to the success of this mission. Please continue to keep the \ndata\nflowing as it will provide a valuable resource for students in the future.\n\nThe stats continue – speeding along at around 17,500 mph, FUNcube-1, \nwhich had\na launch mass of just 982 grams, has completed more than 10,500 orbits \nof the\nearth. This means a total distance travelled of more than 260 million miles.\n\nAll telemetry sensors continue to provide valid data, real time, whole orbit\nand high resolution channels alike. The flight code is really robust and we\nhave only had three unexpected “events” since launch. Two of these we \nbelieve\nto have been caused by noise of the command receiver being incorrectly\ninterpreted as a command and only one appears to have been caused by a RAM\nerror. The battery and solar panels also continue to work perfectly and \nprovide\na very positive power budget.\n\nWe have sent out many Fitter messages for school and other similar events.\nEarlier this week there was a demonstration at Thorne Green Top School in\nYorkshire.\n\nHere is a report from Dave EI4HT/M0GIW:\nGood Morning All\n\nFirstly -thanks to all for your help, we had a great morning at Green \nTop and\nthe highlight was FUNcube.\n\n I started with a slide show talking about communications from cave \npaintings\nall the way up to smartphones, we looked at space communications and travel\nfrom Sputnik to Astra and Apollo to the Millennium Falcon! We spoke about\nsatellites and how they are used every day and how we all got to watch \n“I’m A\nCelebrity” via Satellite last night from Australia.\n\nI brought in lots of props too, some old Motorola MX330 radios, some PMR \n446,\nand a marine band radio .I also had a small model of a CubeSat that I \nknocked\nup over the weekend, I also passed around some NOAA images from last week’s\nAbigail storm and I had a few QSL cards from ISS and MIR from years ago \nwhen I\nlived in Ireland.\n\nThe FUNcube pass was great, really strong signals, I had my turnstile \nand FCD\nset up and had audio through speakers and used the class projector to show\nSatpc32 and the Dashboard.\n\nThere was a great buzz of excitement when we got the first packet and even\nmore when the Fitter messages came through. The kids were fascinated to \nsee the\nsignal arrive just as the software predicted and then hear the telemetry and\nthe decode.\n\nAfter the pass we were able to look at the Warehouse online and print \noff the\nQSL card and certificate.\n\n I didn’t get a chance to take many pics but Mrs Overson will update the\nSchool Blog and she took lots of pics.\n\nhttp://greentopschool.co.uk/blog\n\nOnce again thanks to all at FUNcube, looking forward to Tim Peake on the ISS\nin the New Year and planning another visit to the School then.\n\n Regards\nDave EI4HT / M0GIW\n\nPS: I was back dropping my own kids off this morning and Mrs Overson told me\nthey have printed a QSL card and Certificate for each of the students \nand they\nhave used them for their class journals.\n\n\nAs well providing a great educational resource, FUNcube-1 operates at night\nand generally at weekends with the linear transponder active for radio \namateurs\nto use for communications. The transponder continues to provide an excellent\nservice. As users will be aware, the transponder uplink frequencies vary \nwith\nreceiver temperature. The RX temp telemetry channel is the best one to \nuse for\ntracking this effect. This does make it quite difficult to use full computer\ncontrol for transponder operations and we have already developed new \noscillator\ncircuits to improve this performance for future missions.\n\nFor the telemetry uplinked to the Data Warehouse, it is possible to download\nspecial Certificate or QSL Card here\nhttp://amsatuk.me.uk/on/funcube_qsl.php\nand, for transponder users, the “73 on 73 award” continues at\nhttp://amsat-uk.org/funcube/73-on-73-award/\n\nThe Nayif-1 CubeSat mission, which includes a full FUNcube payload, is\nexpected to be launched into a similar orbit in the first half of next \nyear and\nwill provide an additional level of service to the community.\n\nMeanwhile we hope everyone will continue to have fun with FUNcube-1!\n\nSee:\nhttp://funcube.org.uk/2015/11/20/the-second-birthday-of-funcube-1/\n\n\n[ANS thanks Graham, G3VZV and the FUNcube-1 Ops Team for the above \ninformation]\n\n\n---------------------------------------------------------------------\n\n\nFM Repeater Test at IO-86 Satellite\n\n\nA confirmation for the upcoming test of the FM Repeater on IO-86 Satellite\n(LAPAN-A2/ORARI), has been announced and would be conducted this weekend:\n- Saturday, 21 Nov 2015, at 02:30 UTC - 04:50UTC\n- Sunday, 22 Nov 2015, at 02:55 – 05:00 UTC\nVoice Repeater info:\n- Uplink 145.880 Mhz tone 88,5\n- Downlink 435.880 Mhz\n\nAMSAT Keplerian data\n0 IO-86\n1 40931U 15052B 15316.15776324 .00001070 00000-0 60618-4 0 9994\n2 40931 6.0030 69.3893 0012877 275.6206 84.2533 14.76374433 6653\n\nAs the satellite was designed for emcomm using handheld radio (the \nreason of\nthe relatively high-power downlink), we would like all reports of \nportable ops\n(handheld radio using some sort of portable directional antenna,\ni.e. CJU / IOio / Moxon / Arrow / etc).\n\nResponses via the amsat-bb\n\n\n[ANS thanks Suryono Adisoemarta – YD0NXX / N5SNN for the above information]\n\n\n---------------------------------------------------------------------\n\n\nAMSAT-LU announces transponder satellite payload and launch\n\n\n(From AMSAT-LU Facebook page:)\nDear friends,\n\nSince several years ago AMSAT Argentina is working to keep alive the \ndream of\nmany amateur radio back into space with a satellite of its own, which is the\ncontinuity of the legendary LuSat-1 of the años1990 and reaping the \nbenefits of\nthe technological advance of our days.\n\nFor this held various technical activities, developing experiments on board\nthe occasional platforms, all with the same objective: to preserve the human\ngroup, enhance their capabilities and spread their resources by guiding \nthem to\nthe education and development of the activity.\n\nIn recent times, AMSAT Argentina has been working in many ways with the\ncompany Satellogic, which already launched three satellites of low orbit:\nCaptain Beto, manolito and tita, two of them are now broadcast telemetry and\ndata in uhf and are identified in the Distinctive LU7AA.\n\nUnder an agreement signed between the two institutions AMSAT-LU provides\nsupport to those missions operate one of the stations of control in uppsala,\nProv. Of BS. As.\n\nCurrently satellogic is facing the construction of a constellation of\nsatellites of observation of the earth and has invited AMSAT-LU to \nparticipate\nin the project of the next two satellites, the ÑUSAT 1 AND ÑUSAT 2, \nriding on\none of them a Linear Transponder Analog Amateur Radio Antenna and its\ncorresponding.\n\nThe experiment which provides AMSAT was tested on several occasions in the\nland, and also on board one of flights in a balloon launched from the \nprov. Of\nthe Pampas. At that time was called carposat, showing a good performance in\nspite of its low power and small size and weight.\n\nOn this occasion, the experiment of AMSAT LU - that has no name yet own \n- will\nbe further reduced in its dimensions and mounted on a plaque radiadora \nof 10 x\n10 cm, in which also won't hold the necessary components for the Source \nof food\nand the duplexer. The package will be installed on the bus from the NUSAT,\nwhich will provide the energy and will be part of a number of other \nexperiments\nthat will carry out this satellite.\n\nThe Transponder receives in the band of UHF and VHF Transmitted in, has a\nbandwidth of 30 Khz and its output power is 200 mw.;\n\nFrequencies of ascent 435.935 ~ 965 Lsb / CW,\nFrequencies of descent 145.965 ~ 935 USB / CW.\nBasic telemetry in 145.900 CW.\n\nThe launch is scheduled for April 2016 with a Chinese launcher in a \npolar orbit\nat 500 km. In Height and an inclination of 97 degrees with respect to the\nequator.\n\nThis is an extraordinary opportunity to our institution, and for all the\nRadioamateurs Argentines, be able to have a new satellite in orbit, \nafter after\nso many years of successful LuSat-1.\n\nSo far, the funds needed for the preliminary activities of recent years, the\nconstruction and the logistics, were provided by a small number of \nmembers of\nthe board of directors and partners of AMSAT-LU. Now come the largest \neconomic\npositions for the completion of the electronics and integration with the\nsatellite principal.\n\nIn order to comply with this circumstance, it has been proposed the\nestablishment of a list where it will include the names and distinctive \nsigns\nof all those who are able and willing to work together, and then give them a\ncertificate alluding to his gesture.\n\nThe neighbors of the autonomous city or the great Buenos Aires, can perform\ntheir collaboration personally during the monthly meetings of AMSAT-LU. \nAlso at\nthe headquarters of the RC Qrm Belgrano, permanent partners of AMSAT-LU. \nIf I'd\nbe interested in making donations from other sites away, we'll let you \nknow the\nway to make their contribution.\n\nAlso, we would like to take this opportunity to invite all the partners of\nAMSAT and amateur radio colleagues who are interested in suggest the \nname and\nthe logo for our next satellite Argentine, write to us on the page of AMSAT\nArgentina in Facebook or sending it by e-mail to\[email protected].\n\n\n[ANS thanks Ignacio Mazzitelli, LU1ESY for the above information]\n\n\n---------------------------------------------------------------------\n\n\nSpace Brazilian Agency With Amateur radio PY2SDR LABRE/AMSAT-BR\n\n\nBrasilia, November 20, 2015 - The Brazilian Space Agency (AEB) received on\nTuesday (17) the visit of amateur Edson Wander Pereira, the first to receive\nand decode the data sent by Serpens-1 cubesat.\n\nThe nanossatélite was launched into orbit from the International Space \nStation\n(ISS), the 17th of last September.

After 4 months of\noperations, the satellite is healthy and stable, although unfortunately \nwe have\nnot been able to meet all of the mission objectives. Initial contact \nwith the\nsatellite was established relatively smoothly and we received a lot of good\ndata, both through our own ground station but also via the network of \nyou radio\namateurs who have been very generous with your time and help.\n\nWe achieved a power stable state early on, with good comms (uplink and\ndownlink) established within the first few days. We deployed the solar \npanels\nsuccessfully, and managed to return to a good and stable power state after\ndeployment. The ADCS has been challenging from the start, and continues \nto be\nchallenging – we have struggled to accurately determine the satellite tumble\nrate and get it under control (more detail on that is included below). \nWe know\nthat the satellite has seen some very high spin rates for various reasons,\nincluding some inherent design/magnetic characteristics which have become\napparent.\n\nDespite many attempts, we have unfortunately not been able to deploy the \nsail,\nand having recently thoroughly analysed and investigated the possible \ncauses,\nmission events and ground test data and history, we are now reaching the\nconclusion that achieving successful sail deployment is very unlikely. Again\nthere is more detail on that in the main body of text below.\n\nWe thank you for your patience and would like to apologise for not keeping\nyou updated on mission progress as often as we’d hoped. The operations phase\nhas been a learning and sometimes stressful experience for all of the \nteam at\nSSC, with a lot of head scratching and sleepless nights involved.\n\nHere is some more detailed information regarding what progress and\nachievements have been made during the operations to date.\n\n• After the launch on the 10th of July, and the first week in orbit, with a\npower safe and healthy satellite, the operation passed from the LEOP \nphase to\nthe ADCS Commissioning phase. This second phase was estimated to last \nbetween\nthree and four weeks; this proved to be optimistic.\n\n• Although the spin up of the S/C was much higher than expected and \nsaturated\nthe sensors, the SU simulations and the available data suggested a large \nZ-spin\nrate on DOS which was confirmed by the B-field and MEMS magnetometry\nmeasurements. To induce a bigger difference in the Moments of Inertia \n(MoI) of\nthe two non-longitudinal axes, the decision was taken to deploy the solar\npanels. This operation was performed the 10th of August.\n\n• More than a month after the launch the satellite was really healthy, power\nsafe and with great comms through newly developed software defined radio and\ndatabase backend operations. Although the stabilization wasn’t achieved even\nwith the solar panel deployment, at one month from the launch the team \ndecide\nto proceed with the sail deployment.\n\n• This decision was agreed with DLR that confirmed that tumbling rates \nwere no\nissue for the sail deployment, because the Moments of Inertia increase \nrapidly\nslowing down the tumble rate. DLR has performed a deployment test on \nGossamer\nwhile tumbling before coming to this opinion.\n\n• On the 15th of August, the first attempt for sail deployment was \nperformed,\nthe command was sent and the acknowledgement from the S/C was received, \nbut no\ncurrent was drawn from the boom deployer motor. Multiple experiments were\nperformed to try and determine the cause of sail deployment failure.\n\n• At this point, after a thorough investigation, the most plausible \nhypothesis\nand justification seems to be a physical disconnection of the motor cables.\n(Note that after the vibration test, it wasn’t possible to physically \ninspect\nthe connection due to the design itself of the S/C)\n\nOur simulations showed that with the actual configuration (deployed solar\npanels, undeployed sail) the decay time should be 20 years circa.\n\nThe aim now is to exercise and exploit the parts of the satellite that are\nworking, and gain more confidence and experience with the SU ADCS \nsystem, the\nISIS TRXUV and solar panels, and the SSC SDR groundstation and database \ntools\nto explore better the interaction of the panel circuitry with the attitude\nstabilisation. That will allow us to improve our performances in the next\nmissions.\n\n From here, the team have worked hard to take images of the Earth and \nvia SU’s\nCubeSense camera – which we are delighted to show you today. This would \nnot be\npossible without the dedication from the SSC team here and, of course, the\namateur telemetry you kindly send us. We are going to continue imaging and\ntesting at higher resolutions too so watch this space.\n\nWe thank you for all the support.\n\nChiara Massimiani, DOS Project manager & Prof Guglielmo Aglietti SSC \nDirector\nand DOS PI\n\nDeorbitSail\nhttp://amsat-uk.org/satellites/telemetry/deorbitsail/\n\nSurrey Space Centre\nhttp://www.surrey.ac.uk/ssc/research/space_vehicle_control/deorbitsail/\n\n\n[ANS thanks AMSAT-UK for the above information]\n\n\n---------------------------------------------------------------------\n\n\nSPROUT SSTV and Digitalker active every Sunday\n\n\nSlow Scan TV (SSTV) images in Scottie 1 format will be transmitted from the\nSPROUT satellite every Sunday (Japanese Standard Time) on 437.600 MHz FM \n(+/- 9\nkHz Doppler shift). The Digitalker will also be active.\n\nSPROUT, a 20 x 20 x 22 cm amateur radio nano-satellite with a mass of \n7.1 kg,\nlaunched successfully with the L-band (1236.5 MHz/1257.5 MHz/1278.5 MHz)\nSynthetic Aperture Radar (SAR) satellite ALOS-2 on May 24, 2014 at 0305 UT.\nSPROUT is in a 654 km, 97.9 degree inclination Sun Synchronous Orbit (SSO).\n\nSPROUT (Space Research On Unique Technology) was built by students from \nNihon\nUniversity and its objectives are:\n1. Operation of satellite by radio amateurs.\nA FM Digitalker will enable the satellite to speak to amateurs around \nthe world.\nThe Voice Message Box will record transmissions from radio amateurs and play\nthem back.\nPre-loaded images from the Message Gallery can be transmitted using Slow \nScan\nTV (SSTV).\nPictures of the Earth can be transmitted by SSTV and radio amateurs can\nreceive it using free software such as MMSSTV. As part of the Earth mapping\nproject the team ask radio amateurs to contribute pictures they have \nreceived\nfrom the satellite for display on the SPROUT website.\nThe satellite also has a packet radio Digipeater and Text Message Box \nfunction.\n\n2. Demonstration of the deployment of the combined membrane structure and\nverification of the design method of the structure SPROUT has a triangular\nmembrane supported by two tubes like framework. They are folded and\nstored in the satellite before the launch. After the launch, the \nnitrogen gas\nis injected into the tubes in space, and they extend, so that the membrane\ndeploys (called “combined membrane structure”).\n\n3.
