ARISS One Step Closer to Flying New Equipment to ISS

On behalf of the ARISS International team, I am proud to announce that on Friday September 29th the ARISS team submitted the InterOperable Radio System (IORS) Safety Data Package to NASA for review! Our next step in this process is the Safety Review, which is planned for November 2

Submitting this was a phenomenal accomplishment!! Particularly since the entire Safety Data Package was developed exclusively by our ARISS volunteers---something we have never done before Prior to this submittal, all safety packages---from Owen Garriott's in the early 1980s to today--were developed with contractors from NASA, ESA or Energia And might I say at substantial expense I am pleased that the ARISS team did it ourselves!

Why is this important? Two reasons:

1) This is a very major IORS milestone We cannot get to orbit without successfully completing the safety review process and getting our hardware certified for flight

2) Developing the safety package exclusively with volunteers is an innovative and gutsy approach to keep costs down and get the hardware flown sooner Otherwise we probably would have to slip launch 1-2 years while we acquired additional funding to get this done

NASA Human Spaceflight Safety Certification is a four-step process--- Phase 0, Phase 1, Phase 2 and Phase 3 The material we submitted covers the first three of the four phases As part of Phases 0, 1 and 2, we need to make sure NASA understands our design And we need to show NASA that we understand all the potential hazards that our hardware systems could introduce to ISS and how we have mitigated (or prevented) these hazards One example is to demonstrate to NASA that our IORS was designed with electrical wiring and circuit breakers that possess adequate features and sufficient margin to prevent an electrical shock or fire on-board the ISS Critically important stuff! The final phase (Phase 3) will be complete when we have completed all testing and NASA inspection of our flight hardware and NASA deems it flight worthy At that point the IORS will be flight certificated and we can fly! Currently we are looking to March-May 2018 for flight readiness

For those not following ARISS hardware development very closely, we are developing the IORS to replace most of the on-board radio hardware It is called "interoperable" because it is being designed to be operated anywhere on ISS But specifically, it will be used in the two areas with ISS Ham legacy antennas: the Columbus Module and the Russian Service Module Interoperability allows us to leverage existing ISS power cables, it can be moved between modules in the event of on-orbit failures, and it supports common training and operations The IORS is the most complex in-cabin hardware system we have ever designed, built, tested and flown as a volunteer team We will remove the 3 watt Ericsson handheld radio system, initially certified for flight in 1999, and the Packet module--both of which have recently had issues-and install a brand-new, specially modified 25 watt JVC Kenwood D710GA radio to enable a multitude of new or improved capabilities on ISS, including voice repeater and be tter APRS operations A key development is the Multi-Voltage Power Supply (MVPS), which interfaces with multiple electric outlet connection types on ISS and provides a multitude of power output capabilities for our current and future ARISS operations and amateur radio experimentation It will also allow our Ham Video system to have a dedicated power outlet, eliminating the outlet sharing we have now, which shuts down Ham Video at times

This effort would not be possible without the dedication and persistence of our IORS development team of volunteers They have been working tirelessly behind the scenes to provide an outstanding amateur radio experience for all Our IORS development team includes: Lou McFadin, W5DID, our Chief Engineer; Kerry Banke, N6IZW, the MVPS lead designer; Bob Davis, KF4KSS, the MVPS Mechanical enclosure designer; Ed Krome, K9EK, supporting IORS thermal control and cabin noise dissipation; Dave Taylor, W8AAS, our JVC Kenwood D- 710 development liaison; Bob Bruninga, WB4APR, our APRS and D-710 operations expert; Shin Aota, JL1IBD, and Phil Parton, N4DRO for all their phenomenal support from JVC Kenwood; Kenneth Ransom, N5VHO, our operations lead; and our safety package team-Ken Ernandes, N2WWD, and Gordon Scannell, KD8COJ Kudos to all on a fantastic effort!

Designing, building and testing the IORS is a huge undertaking and very expensive We need to build ten (10!) units to support flight hardware, flight spares, testing, and training across the international team Hardware parts, development tools, fabrication, testing, and expenses to certify the IORS are expected to cost approximately $150,000 And the hard part (i e most expensive part) is just now starting So please consider making a donation to ARISS to take our hardware system from dream to reality You can donate to ARISS directly through the AMSAT web site at: http://www ariss org/donate html ALL donations go directly to ARISS

Thank you for all your support to inspire, engage and educate our youth to consider wireless communications and amateur radio, and to pursue STEAM careers through our exciting human space exploration and amateur radio endeavor!

Sputnik Replica - The Transmitter

Stefan's Radio Blog posted at: http://www radio cc/post/franks-sputnik-transmitter

Frank's Sputnik Replica - The Transmitter

In the January edition of the RAZzies magazine Frank Waarsenburg PA3CNO continued to report about building a replica of the original Sputnik 1 transmitter

In his interesting article he writes about the difficulties and obstacles he faced: Missing data for winding the coils, errors in 2p19b datasheets and a critical bug in the schematics He des- cribed his approaches to tackle these problems (See the blog page for a photo of the project )

I think for everyone who is interested in understanding the Sputnik 1 transmitter or who wants even to build a replica Frank's article is a must read Please note that the RAZzies is a Dutch HAM magazine If you don't understand Dutch simply use the Google translator or similar tools in order to get a translation

PE1ITR Posts Impressions and Photos From AMSAT-DL Annual Meeting

http://pe1itr com/satellite/verslag-amsat-dl-jahreshauptversammlung- 2017 htm (Ed note - Google translate helps)

On September 30th I visited with Jack, PA0BOJ, the AMSAT-DL Jahreshauptvers- ammlung 2017 We left Bochum at 7:15 am and at 8:00 we were home again It was a long and interesting day, revealing that it was a blast of activities

In addition to the usual administrative issues, the central theme of the annual meeting was the developments of and around the future Es'hail- 2 satel- lite The expectation is now that the satellite will be launched in Q2 2018

There were lectures on the construction of the various ground stations and their current status It was nice to see that in the command, ground stations built in extensive switching options, which also included space for experiments

Also the well-known LEILA is built in custom form and there will be a websdr available to monitor the downlink signal

There was special attention to the digital television capabilities of this satellite In this context I found the reading of Thomas, DG5NGI, interest- ing, in which he told me about the DVB-S2 mode that one wants to use And even talked about DVB-S2X as a possible next step afterwards I had not heard of DVB-S2 before, but now I understand that DVB-S2 is more packet oriented than DVB-S, so there are more opportunities in the data stream build-up Spoken was about FEC, Modulation, BBFRAMES, Dynamic Coding and Transport Capability

It was also clear that for experimenting with datv on the wideband trans- ponder, coordination between users is needed The BATC is developing a website that provides more information in this performance

There was also a dummy S/X band P4A transponder at the meeting Jack had taken his DVB-S S-band television transmitter and X-band receiver And I'm my ssb/cw S/X band equipment With this we thoroughly tested the dummy transponder I even made my first qso about this phase4a style S/X band dummy transponder with Achim DH2VA, which was on the other side of the room We have therefore exchanged 59 +++ reports And we were again a nice experience richer

AMSAT Phase 4 Groundstation Report for the Week 3 October 2017

Michelle Thompson, W5NYV, has released the Weekly Report for the AMSAT Groundstation Team

https://www youtube com/watch?v=tcefTXTj9b0&feature=youtu be

Her full report, including notes are posted with the video (click on 'See More') This week Michelle discusses our simplified pi/2 BPSK decoder, working under the assumption that symbol timing and phase have already been resolved to a single sample per symbol

This work fits into the much larger picture of acquiring phase, timing of symbols, demodulation, decoding, and correlation to the fixed patterns of the Start of Frame field in the physical layer header that helps define each DVB-S2 frame

The DVB-S2 physical layer header is sent using a modulation scheme called pi/2 BPSK This scheme is defined in the standard Since we're using GNU Radio as our reference design, we decided to make a custom block in GNU Radio to do this This block will evolve to include our specific type of correlation for the Start of Frame as well

We started with the definition in the specification where, "SOF shall correspond to the sequence 18D2E82HEX (01-1000- -0010 in binary notation, the left-side bit being the MSB of the PLHEADER)" 90 degree BPSK, so in complex notation, it's…"The PLHEADER, represented by the binary sequence (y1, y2, y90) shall be modulated into 90 p/2BPSK symbols according to the rule:

I sub 2i-1 = Q sub 2i-1 = (1/v2) (1-2y sub 2i-1), I sub 2i = - Q sub 2i = - (1/v2) (1-2y sub 2i) for i = 1, 2, , 45 "

[Ed note: examples and explanation are in the video]

Assuming that the demodulation is correct, the next step from here is to take our start of frame and look for received patterns that match it When this happens, we will produce a tag Tags in GNU Radio are synchronized chunks of information that are attached to samples It is like metadata that can be used by other blocks For this block, we are going to follow the conventions in the general correlation estimation block This means that there will be several tags that can be used by downstream blocks that need them Those downstream blocks have already implemented functions that consume the tags, so if we produce them, it makes for more useful flow graphs ?
