Roll Call—Rosalie White, K1STO
Welcome—Frank Bauer, KA3HDO
Frank Bauer thanked the team for participating in the monthly meeting. He relayed that at the largest ham radio convention in the US, Hamvention near Dayton, Ohio, many visitors from the US and around the world expressed appreciation for all ARISS team members’ activities performed for youth, ham operators, the public, and for amateur radio.
1. Call for Acceptance of Minutes—Rosalie White, K1STO
Summary: The minutes from the ARISS-International Monthly Meeting on April 16, 2019 were finalized by Rosalie White on April 24, 2019. After a review was completed on May 20, 2019, the minutes were distributed to ARISS Delegates.
Discussion: Gaston Bertels made a motion to accept the minutes as written. Ciaran Morgan seconded the motion. There were no objections from any delegates, so the minutes as distributed by Rosalie White were approved.
2. 2019 Face-to-face Meeting Plans, Canada—Glenn MacDonell, VE3XRA and Chet Latawiec, VE3CFK
Summary: The ARISS-Canada Delegates will offer more information to regarding the 2019 face-to-face meetings (Hardware Meeting, 25 June and ARISS-I Delegates Meeting, 26-28 June) at the Canadian Space Agency (CSA).
Discussion: Glenn MacDonell and Chet Latawiec continue to look at transportation logistics for going to and from the hotel and the airport. They contacted Montreal area amateur radio clubs to ask if some members can provide transportation. Taxis are an option and several attendees will have vehicles. Attendees need to submit a SurveyMonkey survey as soon as possible to Carol Jackson; that information will help determine transportation options. On May 20, Carol Jackson sent an email reminder about the survey and included all meeting details; please submit the SurveyMonkey survey now to her.
Glenn MacDonell explained that the CSA facility is an office building with very little to visit; astronauts train in classrooms. However, there are activities in Montreal for families of team members to see and do.
The most important things for attendees are:
- ensure the hotel reservation is made by May 24,
- those who will be inside CSA to attend meetings, submit passport information to CSA, and
- submit the SurveyMonkey survey now to Carol Jackson.
Glenn MacDonell will ask CSA to send an email to team members after they submit their passport information, verifying to team members that the information was received.
Chet Latawiec reported that a place will be chosen for a dinner to be held one evening for all attendees. He relayed that CSA and the hotel are looking forward to having the ARISS team arrive. If a question or problem occurs regarding room reservations, contact one of the two ARISS-Canada Delegates.
Tony Pellerin, the CSA representative working with ARISS-Canada, confirmed that a director of space exploration for CSA will be attending part of the meeting to give a presentation on Canadian plans for Gateway. Canada was the first country to give a firm commitment to the international Gateway program.
For those not able to come to Montreal, Frank stated that a GoToMeeting will be running during the ARISS meetings.
3. Status, HamTV—Oliver Amend, DG6BCE for Emanuele D’Andria, I0ELE
Summary: The HamTV unit was delivered back to Earth, shipped to Italy, and Emanuele D’Andria reported that the shipment arrived there safely. He will discuss what is happening now.
Discussion: Emaneuele D’Andria was unable to attend the telecon meeting; Oliver Amend gave an initial report. With a great deal of help and support from NASA and ESA and many other helping hands, the HamTV system was delivered to Kayser Italia. The company has already performed some first investigations; the unit was powered up, and initial electrical functional tests were performed. It was observed that the consumed power was not as high as it should be—1.6 amps versus 4.4 amps nominal expected in RF mode, whereas the LED status was nominal. There was no video transmission. The next step will be checking the internal power supply distribution unit. No date has been set yet for further tests, Kayser Italia is performing the failure investigation activities upon an “available time” basis.
4. Update, Interoperable Radio System—Frank Bauer, KA3HDO
Summary: Frank Bauer will cover further details from last month’s testing of the Interoperable Radio System (IORS) at Johnson Space Center in Houston.
Discussion: As reported at last month’s ARISS-I meeting, Lou McFadin and Kerry Banke were at Johnson Space Center for tests on the new Interoperable Radio System. EMI and EMC tests were performed on the flight-identical unit of the multi-voltage power supply and the Kenwood radio.
Recently, NASA added more stringent requirements to a number of their testing sequences due to problems caused by the several hundred experiments now onboard the ISS. The new tests were not part of the battery of tests that were passed successfully by the ARISS breadboard power supply system two years ago. Also, those previous tests were only on the power supply; the new tests were performed on the whole IORS system and included both the Russian and the Columbus module requirements.
A few issues were seen during these new tests. NASA now has a very tight radiated emissions requirement. Some of the emissions from the transmitter were higher than the specification. The team is waiting for the final test report from NASA, but after returning home, Kerry Banke recreated the NASA susceptibility tests, made a few minor changes to things, and feels future susceptibility tests will be successful. The team will look into other issues and fixes or be able to get a waiver.
The testing was a slight setback for ARISS, but the team feels it can have the system ready for flight by the end of the year. Scheduling with NASA for tests is always a challenge, though, and NASA is still modifying the tests for the new requirements.
Rosalie White thanked the hardware team and everyone involved in all of these projects.
The next meeting will be June 18, 2019 at 1100 UTC.
