ANS publishes news related to Amateur Radio in Space\nincluding reports on the activities of a worldwide group of Amateur\nRadio operators who share an active interest in designing, building,\nlaunching and communicating through analog and digital Amateur Radio\nsatellites.\n\nThe news feed on http://www.amsat.org publishes news of Amateur\nRadio in Space as soon as our volunteers can post it.\n\nPlease send any amateur satellite news or reports to:\nans-editor at amsat dot org.\n\nIn this edition:\n\n* ARISS One Step Closer to Flying New Equipment to ISS\n* VUCC Awards/Endorsements for September 2017\n* Sputnik Replica - The Transmitter\n* PE1ITR Posts Impressions and Photos From AMSAT-DL Annual Meeting\n* AMSAT Phase 4 Groundstation Report for the Week 3 October 2017\n* COMET Program Training\n* Get Ready for the 2017 AMSAT Space Symposium and Annual Meeting\n* Satellite Shorts From All Over\n+ Congratulations to Alex N7AGF\n+ Daily DX Report\n+ Gérard Auvray, F6FAO Slient Key\n\n\nSB SUN @ AMSAT $ANS-281.01\nANS-253.01 AMSAT News Service Weekly Bulletins\n\nAMSAT News Service Bulletin 281.01\n>From AMSAT HQ KENSINGTON, MD.\nSeptember 10, 2017\nTo All RADIO AMATEURS\nBID: $ANS-281.01\n\n\nARISS One Step Closer to Flying New Equipment to ISS\n\nOn behalf of the ARISS International team, I am proud to announce\nthat on Friday September 29th the ARISS team submitted the\nInterOperable Radio System (IORS) Safety Data Package to NASA for\nreview!  Our next step in this process is the Safety Review, which is\nplanned for November 2.\n\nSubmitting this was a phenomenal accomplishment!!  Particularly\nsince the entire Safety Data Package was developed exclusively by our\nARISS volunteers---something we have never done before.  Prior to\nthis submittal, all safety packages---from Owen Garriott's in the\nearly 1980s to today--were developed with contractors from NASA, ESA\nor Energia.  And might I say at substantial expense.  I am pleased\nthat the ARISS team did it ourselves!\n\nWhy is this important?  Two reasons:\n\n1) This is a very major IORS milestone. We cannot get to orbit\nwithout successfully completing the safety review process and getting\nour hardware certified for flight.\n\n2) Developing the safety package exclusively with volunteers is an\ninnovative and gutsy approach to keep costs down and get the hardware\nflown sooner.  Otherwise we probably would have to slip launch 1-2\nyears while we acquired additional funding to get this done.\n\nNASA Human Spaceflight Safety Certification is a four-step process---\nPhase 0, Phase 1, Phase 2 and Phase 3.  The material we submitted\ncovers the first three of the four phases.  As part of Phases 0, 1\nand 2, we need to make sure NASA understands our design.  And we need\nto show NASA that we understand all the potential hazards that our\nhardware systems could introduce to ISS and how we have mitigated (or\nprevented) these hazards.  One example is to demonstrate to NASA that\nour IORS was designed with electrical wiring and circuit breakers\nthat possess adequate features and sufficient margin to prevent an\nelectrical shock or fire on-board the ISS.  Critically important\nstuff!  The final phase (Phase 3) will be complete when we have\ncompleted all testing and NASA inspection of our flight hardware and\nNASA deems it flight worthy.  At that point the IORS will be flight\ncertificated and we can fly!  Currently we are looking to March-May\n2018 for flight readiness.\n\nFor those not following ARISS hardware development very closely, we\nare developing the IORS to replace most of the on-board radio\nhardware. It is called \"interoperable\" because it is being designed\nto be operated anywhere on ISS.  But specifically, it will be used in\nthe two areas with ISS Ham legacy antennas: the Columbus Module and\nthe Russian Service Module. Interoperability allows us to leverage\nexisting ISS power cables, it can be moved between modules in the\nevent of on-orbit failures, and it supports common training and\noperations.  The IORS is the most complex in-cabin hardware system we\nhave ever designed, built, tested and flown as a volunteer team. We\nwill remove the 3 watt Ericsson handheld radio system, initially\ncertified for flight in 1999, and the Packet module--both of which\nhave recently had issues-and install a brand-new, specially modified\n25 watt JVC Kenwood D710GA radio to enable a multitude of new or\nimproved capabilities on ISS, including voice repeater and be\n tter APRS operations.  A key development is the Multi-Voltage Power\nSupply (MVPS), which interfaces with multiple electric outlet\nconnection types on ISS and provides a multitude of power output\ncapabilities for our current and future ARISS operations and amateur\nradio experimentation.  It will also allow our Ham Video system to\nhave a dedicated power outlet, eliminating the outlet sharing we have\nnow, which shuts down Ham Video at times.\n\n\n\nThis effort would not be possible without the dedication and\npersistence of our IORS development team of volunteers.  They have\nbeen working tirelessly behind the scenes to provide an outstanding\namateur radio experience for all.  Our IORS development team\nincludes: Lou McFadin, W5DID, our Chief Engineer; Kerry Banke, N6IZW,\nthe MVPS lead designer; Bob Davis, KF4KSS, the MVPS Mechanical\nenclosure designer; Ed Krome, K9EK, supporting IORS thermal control\nand cabin noise dissipation; Dave Taylor, W8AAS, our JVC Kenwood D-\n710 development liaison; Bob Bruninga, WB4APR, our APRS and D-710\noperations expert; Shin Aota, JL1IBD, and Phil Parton, N4DRO for all\ntheir phenomenal support from JVC Kenwood; Kenneth Ransom, N5VHO, our\noperations lead; and our safety package team-Ken Ernandes, N2WWD, and\nGordon Scannell, KD8COJ.  Kudos to all on a fantastic effort!\n\nDesigning, building and testing the IORS is a huge undertaking and\n*very* expensive.  We need to build ten (10!) units to support flight\nhardware, flight spares, testing, and training across the\ninternational team.  Hardware parts, development tools, fabrication,\ntesting, and expenses to certify the IORS are expected to cost\napproximately $150,000.  And the hard part (i.e. most expensive part)\nis just now starting.  So please consider making a donation to ARISS\nto take our hardware system from dream to reality.  You can donate to\nARISS directly through the AMSAT web site at:\nhttp://www.ariss.org/donate.html.  ALL donations go directly to ARISS.\n\nThank you for all your support to inspire, engage and educate our\nyouth to consider wireless communications and amateur radio, and to\npursue STEAM careers through our exciting human space exploration and\namateur radio endeavor!\n\n[ANS thanks Frank Bauer KA3HDO for the above information]\n\n---------------------------------------------------------------------\n\nVUCC Awards/Endorsements for September 2017\n\nThe VUCC Standings for September 30th are still not\nwithout problems.

He des-\ncribed his approaches to tackle these problems. (See the blog\npage for a photo of the project.)\n\nI think for everyone who is interested in understanding the\nSputnik 1 transmitter or who wants even to build a replica Frank's\narticle is a must read. Please note that the RAZzies is a Dutch\nHAM magazine.

We left Bochum at 7:15 am and at 8:00 we were home\nagain. It\nwas a long and interesting day, revealing that it was a blast of\nactivities.\n\nIn addition to the usual administrative issues, the central theme of\nthe\nannual meeting was the developments of and around the future Es'hail-\n2 satel-\nlite. The expectation is now that the satellite will be launched in\nQ2 2018.\n\nThere were lectures on the construction of the various ground\nstations and\ntheir current status. It was nice to see that in the command, ground\nstations\nbuilt in extensive switching options, which also included space for\nexperiments.\n\nAlso the well-known LEILA is built in custom form and there will be\na websdr\navailable to monitor the downlink signal.\n\nThere was special attention to the digital television capabilities\nof this\nsatellite. In this context I found the reading of Thomas, DG5NGI,\ninterest-\ning, in which he told me about the DVB-S2 mode that one wants to\nuse. And\neven talked about DVB-S2X as a possible next step afterwards. I had\nnot\nheard of DVB-S2 before, but now I understand that DVB-S2 is more\npacket\noriented than DVB-S, so there are more opportunities in the data\nstream\nbuild-up. Spoken was about FEC, Modulation, BBFRAMES, Dynamic Coding\nand\nTransport Capability.\n\nIt was also clear that for experimenting with datv on the wideband\ntrans-\nponder, coordination between users is needed. The BATC is developing a\nwebsite that provides more information in this performance.\n\nThere was also a dummy S/X band P4A transponder at the meeting. Jack\nhad taken his DVB-S S-band television transmitter and X-band receiver.\nAnd I'm my ssb/cw S/X band equipment. With this we thoroughly tested\nthe\ndummy transponder. I even made my first qso about this phase4a style\nS/X\nband dummy transponder with Achim DH2VA, which was on the other side\nof\nthe room. We have therefore exchanged 59 +++ reports. And we were\nagain\na nice experience richer.\n\n[ANS thanks Rob, PE1ITR, and AMSAT-DL for the above information]\n\n---------------------------------------------------------------------\n\nAMSAT Phase 4 Groundstation Report for the Week 3 October 2017\n\nMichelle Thompson, W5NYV, has released the Weekly Report for the AMSAT\nGroundstation Team.\n\nhttps://www.youtube.com/watch?v=tcefTXTj9b0&feature=youtu.be\n\nHer full report, including notes are posted with the video (click on\n'See More'). This week Michelle discusses our simplified pi/2 BPSK\ndecoder, working under the assumption that symbol timing and phase\nhave already been resolved to a single sample per symbol.\n\nThis work fits into the much larger picture of acquiring phase, timing\nof symbols, demodulation, decoding, and correlation to the fixed\npatterns\nof the Start of Frame field in the physical layer header that helps\ndefine each DVB-S2 frame.\n\nThe DVB-S2 physical layer header is sent using a modulation scheme\ncalled\npi/2 BPSK. This scheme is defined in the standard. Since we're using\nGNU\nRadio as our reference design, we decided to make a custom block in\nGNU\nRadio to do this. This block will evolve to include our specific type\nof correlation for the Start of Frame as well.\n\nWe started with the definition in the specification where, \"SOF shall\ncorrespond to the sequence 18D2E82HEX (01-1000-....-0010 in binary\nnotation, the left-side bit being the MSB of the PLHEADER)\" 90 degree\nBPSK, so in complex notation, it's…\"The PLHEADER, represented by the\nbinary sequence (y1, y2,...y90) shall be modulated into 90 p/2BPSK\nsymbols according to the rule:\n\n I sub 2i-1 = Q sub 2i-1 = (1/v2) (1-2y sub 2i-1), I sub 2i =\n - Q sub 2i = - (1/v2) (1-2y sub 2i) for i = 1, 2, ..., 45 \"\n\n[Ed. note: examples and explanation are in the video]\n\nAssuming that the demodulation is correct, the next step from here\nis to take our start of frame and look for received patterns that\nmatch\nit. When this happens, we will produce a tag. Tags in GNU Radio are\nsynchronized chunks of information that are attached to samples. It\nis like metadata that can be used by other blocks. For this block,\nwe are going to follow the conventions in the general correlation\nestimation block. This means that there will be several tags that\ncan be used by downstream blocks that need them. Those downstream\nblocks have already implemented functions that consume the tags, so\nif we produce them, it makes for more useful flow graphs.?\n\n[ANS thanks Michelle Thompson, W5NYV for the above information]\n\n---------------------------------------------------------------------\n\nCOMET Program Training\n\nThe COMET Program is pleased to announce the publication of the new\nlesson,\n\"Communicating Winter Weather Surface Impacts\n<https://www.meted.ucar.edu/training_module.php?id=1320>\". This\nlesson will\nintroduce National Weather Service (NWS) forecasters to the benefits\nof\npre-season coordination in understanding the critical needs of\ndecision-makers, particularly the state and local Departments of\nTransportation (DOTs). The strategies used by DOTs to mitigate road\nimpacts\nduring the winter and how the NWS can best support their needs are\nalso\ndiscussed. Learners will gain insight into the common methods of\ncollaboration between the NWS and DOT, and the different types of\nwinter\nweather events in which they work together. Learners will also\npractice\ncommunicating winter weather forecast information that best support\nthe\nconcerns of DOT, including working through a simulation to see the\neffects\nof their communication choices on DOT decisions. The lesson will\ntake about\nan hour to complete (not including the quiz).\n\nThe intended audience for \"Communicating Winter Weather Surface\nImpacts\n<https://www.meted.ucar.edu/training_module.php?id=1320>\" includes\noperational forecasters in U.S. NWS Weather Forecast Offices, and\nothers\nwith general interest in communicating weather information.
