Roll Call—Rosalie White, K1STO
Welcome—Frank Bauer, KA3HDO
Frank Bauer thanked ARISS team members for attending the meeting and for all of the volunteerism and great passion expended on ARISS. The team is doing phenomenal STEM activities for youth and families.
1. Call for Acceptance of Minutes—Rosalie White, K1STO
Summary: The minutes from the ARISS-International Monthly Meeting on July 16, 2019 were finalized by Rosalie White on July 17, 2019. A review was completed on August 19, 2019 and the file was distributed to ARISS Delegates.
Discussion: Glenn MacDonell made a motion to accept the finalized minutes distributed by Rosalie White. Darin Cowan and Gaston Bertels simultaneously seconded the motion. There were no further comments; the minutes were accepted for Carol Jackson to post on the ARISS web site.
2. Summary of InterOperable Radio System—Lou McFadin, W5DID
Summary: During the July ARISS-I telecon, Lou McFadin and Kerry Banke were at NASA Johnson Space Center working in concert with the NASA test and certification team. Lou McFadin reported that power quality tests of the InterOperable Radio System (IORS) would verify that it will not introduce harmful signals back into the ISS power system. Acoustic tests were to be done on noise level of the radio and power supply fans. Completing these tests is a key milestone in preparing the IORS for launch. Lou and Kerry learned what final things must be done for manifesting the system.
Discussion: Lou McFadin reported that the recent tests verified the InterOperable Radio System was compatible with NASA requirements. NASA tests were three-fold. The first was RF tests verifying the IORS could withstand the EMI and EMC requirements. The second set of tests verified the ARISS system was compatible with the three different ISS power sources’ voltages. The third set of tests was on acoustics, noise from the fans.
The team has reached a significant milestone, and will now assemble the actual flight units for the Columbus module and the Russian Service Module. After that, abbreviated tests for EMI/EMC and acoustics will be done at NASA Johnson Space Center for final certification.
On behalf of the whole ARISS team, Frank Bauer congratulated Lou McFadin, Kerry Banke, and the entire IORS team. A weekly tag-up is scheduled with NASA to give a progress report on the IORS. Talks have begun on potential launch dates, possibly for late in the first quarter of 2020.
3. Recent SSTV Events—Sergey Samburov, RV3DR
Summary: The recent SSTV downlinked images that commemorated Owen Garriott’s achievements were very popular with hams and the general public. Over 10,000 images were submitted from people all over the world.
Discussion: Sergey Samburov asked if the team saw improvement in this session’s images. He said in the past, there was a modulation issue, but all has been working better. Frank Bauer said all was good because over 10,000 people downloaded and posted this session’s images. Sergey Samburov added that the success was because good images were provided by team members and the world team worked together as one. Will Marchant compiled the images and had communicated with Richard Garriott beforehand. During the session Kenneth Ransom, Anne Marchant, and Will Marchant worked with images to get them posted in the SSTV Gallery. Sergey Samburov and Frank Bauer thanked Armand Budzianowski and his team for their outstanding work with the awards.
Armand Budzianowski thanked Slawek Szymanowski for his work. Award winners wrote notes saying they received very good signals during this session. There were 2,405 awards sent to applicants. The award team wishes to thank all ARISS volunteers who prepared news releases and/or relayed the news to the world. This publicity is probably why 13% to 14% of applicants were people who said they were shortwave listeners or did not list a ham radio call sign. The publicity is good for ARISS and for ham radio. The award team felt it was an excellent idea to add a short description to each image because this provided fine educational background and history lessons about ARISS and it promoted ham radio in space.
4. Update, HamTV—Oliver Amend, DG6BCE, presented by Rosalie White, K1STO
Summary: A report will be given to update the ARISS team on the current status of the testing of the HamTV unit.
Discussion: The HamTV unit continues to be under failure investigation at Kayser-Italia. The MiniMod board has been sent to the manufacturer’s main technician, Thomas Kleffel, DG5NGI, to begin the inspection of the failed board. Further investigation will continue; Kayser-Italia and Elisa Carrubba gave approval for the removal of the CPU to look for the root cause of failure. Boards had a conformal coating as required for space environments, and unsoldering is difficult.
The failed MiniMod board could be replaced by a flight-identical spare. Software updates of the MiniMod firmware is under discussion but that does not impact the re-flight certification.
The Kayser-Italia team is currently on holiday. Updates will follow in the next few weeks. Repair and retest activity has to be agreed upon with Kayser-Italia. Currently, it appears that hardware flight readiness could be in the end of 2019, with a re-flight possibly targeted for mid-2020.
Gaston Bertels agreed that the information Oliver Amend provided for this discussion is the latest news ARISS has on HamTV.
Frank Bauer reported that several members of the team were approached by SAS, a commercial venture out of Europe that is developing a system named Icecubes. SAS hopes to do work on the ISS similar to what Nanoracks does. He, Gaston Bertels, and Oliver Amend have each been contacted and had discussions with SAS. The company wish to utilize the ARISS L- and S-band antennas to transmit and receive signals outside the ham bands. In exchange, SAS would provide opportunities to ARISS having to do with hardware it will have onboard. Frank Bauer, Oliver Amend, and Rosalie White have discussed the SAS situation and feel ARISS Delegates must think strategically and learn more about this sensitive issue. A delegate-only meeting will be scheduled in the near future for planning. ARISS antennas are a resource being sought after more and more by others, but ARISS antennas are critical for ARISS activities. Because HamTV has not been operational for some time, SAS thought those antennas were no longer being used. SAS did not know ARISS is working to have HamTV onboard again, and that ARISS will use those antennas in the future even more, for such things as validation of ARISS Exploration activities.
Frank Bauer thanked Olga Moncuquet for her interpretation skills.
The next meeting will be September 17, 2019.
