ARISS I Agenda:
Roll Call was handled by Rosalie White, K1STO.
Frank reported that activities at the Dayton Hamvention related to ARISS were very successful. AMSAT held a good forum that included ARISS information, and the room was packed with people. We picked up two highly capable mentor candidates. Frank thanked Gaston, Maurice-Andre, Steve, Brian, and Wayne for providing good ARISS material to be used at the AMSAT forum.
1. Operations/Hardware Status Update— Frank Bauer, KA3HDO
We do not have good updates on how the radio is working in the Service Module, right now. Kenneth said a Russian contact was conducted on May 15 from the Service Module and we received reports that ISS radio was heard reasonably well but it is unclear as to whether the radio was working as well as in the past. The radio was set on high power, and Kenneth believes the radio is working well. The system was switched to packet after the contact and seems to be operating reasonably well, and is probably emanating from the D-700.
In Columbus, the Ericsson seems to be operating fairly well if we have ground stations that are well-equipped and if the ground station monitors the polarity switching needs. The signal sometimes comes up right at the horizon, and then drops off right as the horizon is gone. We have heard some drop outs, and analysis is being performed. Initial results indicate that one of the potential explanations might be that the solar arrays occasionally interfere when they are between the ground station and the antenna on the Columbus Module, but more analysis will be done."
2. Status—Names have been received for ARISS volunteer to be part of the ARISS Project Selection & Use Committee (soon to study the S-Band beacon project)—Frank Bauer, KA3HDO
Input on committee representatives was received from Delegates except for Russia. Thank you to everyone. Mark and Lou will work with this committee.
3. Status—Names have been received for ARISS volunteer to monitor the upgrade of the ARISS web site—Frank Bauer, KA3HDO
Input on names of volunteers was received from Delegates except for Russia. Thank you to everyone, and to Rosalie for coordinating with Delegates to get input for this and for the PS&U Committee. A meeting will soon take place as to progress being made on the web site work.
4. Draft Response to ITU Member States; update—Gaston Bertels, ON4WF
The Ham Video frequencies of 2422 and 2437 MHz have been coordinated with IARU. The frequencies of 2369 and 2395 MHz will only be used when required, when local conditions at the receiving site preclude the use of the 2.4 Ghz frequencies. The 2.3 GHz frequencies will be used under secondary user conditions, and we would cease operations if there any interference is experienced, as per ITU Radio Regulations article 4.4.
ITU has not yet been notified of the Ham Video frequencies.
The Italian administration has not yet answered the remarks from
other administrations regarding the ARISS frequencies.
5. Update—Ham TV Launch on HTV4, Commissioning at end of 2013, Tests of Streaming Program—Gaston Bertels, ON4WF
ESA has weekly teleconferences on Ham Video commissioning. The ARISS Ham Video working group meets weekly via teleconference, as well.
The official announcement is being prepared for the ham radio media about the installation and commissioning of Ham Video on the ISS. Launch is slated for HTV4 on August 4 2013. Commissioning will be done by astronaut Michael Hopkins, KF5LJG, in autumn 2013 or early 2014. The Matera VLBI station, located at the Italian Space Agency's “Centro di Geodesia Spaziale G. Colombo” (CGS) near Matera, south of Italy, will be used for reception of video and audio signals during commissioning transmissions. Their 20-meter dish will facilitate commissioning.
Soon, Gaston will make available some detailed information for the setting up of ground stations for Ham Video reception.
Frank reported that at the Dayton Hamvention, he heard a lot of hams talking and excited after hearing about this future video activity.
6. Update on issues regarding travel for 2013—Frank Bauer, KA3HDO
NASA is using Webex for many of its major meetings because of continuing travel restrictions due to the US government sequestration. If ARISS were to schedule a face-to-face meeting, travel for our NASA Education Office would not be allowed. So travel for the US team to Europe will probably not happen this year.
**************ACTION ITEM – Delegates need to respond to Frank immediately: We can think about a meeting in 2014. Or if we feel we must meet before 2014, Frank suggested thinking about meeting at the AMSAT Symposium in Houston on November 1-3, 2013.
We will send a message to ask each delegate to give an opinion on this. Lou said AMSAT would need to know almost immediately in order to reserve more hotel rooms.
