ARISS I Agenda:
Roll Call — Rosalie White, K1STO
1. Operations/Hardware Status Update—Frank Bauer, KA3HDO
The Ericsson radio in the Columbus module is working well though sometimes signals are not as strong, depending on the trajectory relative to the school and the ISS. The team is still learning what things affect this.
We understand the equipment in the Service Module is not turned on right now, and that Sergey has sent a microphone up for the D-710 that is already there. A few Russian on-the-air activities are planned for the next two Saturdays.
2. Update on CW Beacon—Gaston Bertels, ON4WF
Gaston said we have not received any new input on this project from Kaiser-Italia. Lou reported that the ARISS team is focused on the digital ATV system rather than the CW beacon.
3. Update for Ham TV—Gaston Bertels, ON4WF
The Russian Space Agency has commented recently on our planned S-band activity, and they are doing a review to try to determine if there will be interference problems with a Russian system called ETKC. We are trying to learn about ETKC and whether it is a short-term project or something that will be permanent on the ISS.
Gaston said Cathy Sham felt the team will probably have the flight rules assigned and finalized in time to begin the first commissioning test on March 8. The second commissioning test would be March 9, using a different antenna. A week later would be the third commissioning test, using the best configuration that we find from testing blank transmissions.
ESA’s commissioning consists of an astronaut activating the Ham video system on 4 frequencies at 2 symbol rates (1.3 MSymbols/sec and 2.0 MSymbols/sec), starting with an 8-minute pass over Matera, Italy, where we hope to receive an image. The test will be one way transmissions. Uplinks will be using only European communications systems rather than using ham radio.
If it is determined that our transmissions cause interference on the ground, the complainant would go to their government telecommunications agency who would forward the complaint to the Italian government agency, who would tell ESA to stop the transmissions.
Though it is not an official call sign, during the blank transmissions, the ID embedded in the data stream is Ham TV. The station license used for commissioning couldbe OR4ISS If Ham TV uses a US license, operations must be on the two frequencies that are legal for US licensees to use. Gaston also suggested that ESA could get an experimental license, if needed.
At this point there is no need to change current plans for commissioning and blank transmissions. But we need to determine prior to the blank transmission testing (a month from now) who will be the licensee for Ham TV operations. We need to establish more details for the operational plan, station identification, and frequencies. The Ham TV team should clarify how equipment will be operated so all ARISS-I delegates are in agreement with the plan. Gaston will work with Attila Matas of the ITU to reach an understanding as to how identification can be handled. Frank asked Gaston to compose a fact sheet that explains the key points of Ham TV and the way it will be operated. Most of this information exists, but needs to be pulled together into a succinct document
Frank and the whole team gave a big thank you to Gaston for all he is doing on Ham TV while at the same time, coordinating matters for the upcoming meeting at ESTEC, in addition to all of his other multiple ARISS duties. We greatly appreciate Gaston’s hard work.
4. Update on Russian school/youth contacts—Sergey Samburov, RV3DR
At the last moment, Sergey was not able to attend our teleconference meeting.
5. Updates on 2014 ARISS-International Meeting—Frank Bauer, KA3HDO
Planning continues for our meeting at ESTEC in early April. Frank has emailed the call for reports to be written in advance. The reports will be distributed to be read carefully prior to our meeting. As we discussed earlier, this will give us time at our meeting to focus on the necessary highly strategic topics.
Gaston has circulated updates on attendees, arrivals, and hotel locations. The details on the rooms at ESTEC are being set up. Thursday and Friday, April 3 and 4, will be the ARISS International meeting. Saturday, April 5, will be a meeting focused on technical details at the strategic level.
Delegates continue to work on who from partner space agencies can and should be invited, soon, to our meeting. A major outcome that we desire from their attendance and participation would be an understanding of future agreements that need to be developed. The ARISS team has done excellent educational outreach work over the years with significant equipment in both the Service Module and the Columbus module, and dialogs with the space agencies will be important for continuing with these successes and expanding capabilities for the future.
Keigo asked how soon the agenda would be more finalized, in order to coordinate attendance with outside parties. Frank estimates that an updated agenda could be distributed later this week.
