by n4csitwo＠bellsouth.net 08 Apr '19

08 Apr '19

An International Space Station school contact has been planned with participants at Shaftesbury High School, Winnipeg, Manitoba, Canada on 10 April. The event is scheduled to begin at approximately 15:57 UTC. It is recommended that you start listening approximately 10 minutes before this time.The duration of the contact is approximately 9 minutes and 30 seconds. The contact will be a telebridge between NA1SS and VK6MJ. The contact should be audible over Australia and adjacent areas. Interested parties are invited to listen in on the 145.80 MHz downlink. The contact is expected to be conducted in English. Shaftesbury High School is a public school in the Pembina Trails School Division serving approximately 700 students from grades 9 through 12 in Winnipeg, Manitoba, Canada. Grade 9 students from schools across the division have been invited to Shaftesbury to share in celebrating Canada's role in space through a contact with Canadian Astronaut David Saint-Jacques. Currently in its 50th year, Shaftesbury has been a leader in innovative STEAM projects through the Shaftesbury High Altitude Robotics Project (SHARP) and the Shaftesbury ARISS Telebridge Service (SATS). Recent Mars simulation research conducted by Shaftesbury students has been published for presentation at the 2019 Lunar and Planetary Science Conference in Texas. Participants will ask as many of the following questions as time allows: 1. What is your favorite feature of Earth from space? 2. How has space science changed our lives for the better? 3. Is solar energy the only power source for the ISS? 4. What type of training have you had to support your mental health while in space? 5. How is water used on the space station, and is it fully recycled? 6. What is the most challenging problem you have solved while in space? 7. What do you do for entertainment in space? 8. What scientific discoveries have been made recently on the ISS? 9. How is your diet different on the ISS than on Earth? 10. How significant a threat are space junk and meteoroids to the ISS and have you seen either? 11. How do you deal with being sick or injured in space? 12. How do astronauts celebrate birthdays in space and will you be celebrating an early 50th birthday on the ISS? 13. What effect did the recent hole have on the integrity of the ISS, and how was it fixed? 14. What personal sacrifices have you made to be on the ISS? 15. How often and how do you communicate with family? 16. How has seeing the Earth from space without political borders changed your perspective on how we should treat others and our environment? 17. How will a new toilet system improve life on the ISS? 18. Are you worried about changes to your DNA while in space or about other long term effects on your health? 19. How do countries differ in their training programs as they prepare astronauts for life on the ISS? 20. Access to space is limited to only a select few. Do you foresee a time where everyone can experience space? 21. How important is an Outer Space Treaty as more countries embark on space travel?

Non standard APRS implementation in AI SAT
by John Langner WB2OSZ 08 Apr '19

08 Apr '19

There was a discussion, in another group, about why nothing from AISAT was getting showing up on aprs.fi. K4KDR provided some samples of the signals so they could be analyzed. The direwolf "-dp" option was used to produce a hexadecimal dump, of the frame, so we could see what is going on. --------------------------------- Notice the extra comma after the last address. K4KDR-6>CQ,AISAT*,::CQ-0 :=3747.66N/07736.67W`de K4KDR scott23192(a)gmail.com Virginia FM17es{847 ------ U frame UI: p/f=0, No layer 3 protocol implemented., length = 111 dest CQ 0 c/r=0 res=3 last=0 source K4KDR 6 c/r=0 res=3 last=0 digi 1 AISAT* 0 h=0 res=3 last=0 <-- The “h” bit indicates that the digipeater address has been used It should be 1 in this case. There should NOT be the * character in the address field. digi 2 0 h=0 res=3 last=1 I reformatted this so the bytes would be in groups of 7 so it is easier to read. 000: 86 a2 40 40 40 40 60 “CQ” 96 68 96 88 a4 40 6c “K4KDR” SSID 6 82 92 a6 82 a8 54 60 “AISAT*” <-- WRONG!!!!! The * character is used only for the human readable monitoring format. It should not be a character in the station address. 40 40 40 40 40 40 61 “ “ WRONG!!! Field should not be here if not needed. 03 f0 expected control, protocol 3a 43 :C 020: 51 2d 30 20 20 20 20 20 3a 3d 33 37 34 37 2e 36 Q-0 :=3747.6 030: 36 4e 2f 30 37 37 33 36 2e 36 37 57 60 64 65 20 6N/07736.67W`de 040: 4b 34 4b 44 52 20 73 63 6f 74 74 32 33 31 39 32 K4KDR scott23192 050: 40 67 6d 61 69 6c 2e 63 6f 6d 20 56 69 72 67 69 @gmail.com Virgi 060: 6e 69 61 20 20 46 4d 31 37 65 73 7b 38 34 37 nia FM17es{847 ----------------------------------- This is my analysis: (1) Digipeating does not work normally. A digipeater should only change the via path. The information part should not be changed. Why is it converted into “message” format? (2) Only the needed digipeater fields should be present. If they are not needed leave them out. Don’t fill them with blanks. (3) A station address should never contain the * character. That is only in the human readable standard monitoring format. The * after a station indicates that the H bit is set. (4) When a digipeater uses up an address in the via path, it must set the “H” bit to 1. If it responded to an alias, it should substitute its own callsign. Here is an example of expected behavior: K4KDR-6>CQ,ARISS:=3747.66N/07736.67W`de K4KDR scott23192(a)gmail.com Virginia FM17es K4KDR-6>CQ,RS0ISS*:=3747.66N/07736.67W`de K4KDR scott23192(a)gmail.com Virginia FM17es - ARISS is recognized as an alias by RS0ISS. - RS0ISS substitutes its own call and marks that digipeater field as being used. - The * is not a character in the address. It is the human readable way to indicate that the “H” bit is set. - Only the via path is changed. - The Information part is not changed at all. ------------------ 73, John WB2OSZ

ARISS News Release No. 19-07 Dave Jordan, AA4KN ARISS PR aa4kn(a)amsat.org Bidding is Now Underway - Out of This World ARISS Auction! April 8, 2019 The bidding has begun! The Out of This World ARISS Auction is speeding along! It will run until April 14th at 22:00 UTC. Bidders are moving fast hoping to garner a special astronaut signed brand new JVC Kenwood TS-890S-Bidding is done by going to www.ariss.org and pressing the Auction Website button or by visiting http://www.ebay.com/itm/323770952171. Similar for bidding on a special astronaut signed 6-volume boxed set 2019 ARRL Handbook, but a different URL is used-see http://www.ebay.com/itm/323770952890. Thanks to JVC Kenwood and ARRL, proceeds from the on-line auction will benefit ARISS in its quest to launch a new custom-built higher-power radio system in late 2019 with its voice repeater and improved packet APRS and SSTV capability that thousands of hams can enjoy. The new system will replace the aging, problematic units currently on the ISS. ARISS also needs funding to keep introducing ham radio to thousands of students, teachers, parents, and whole communities-and inspiring students about STEM and radio. Kenwood has been a super supporter of ARISS for years, and it was the company's idea for this special radio to be an exclusive for one ham to own. The limited edition boxed set 2019 ARRL Handbook sold out fast last fall but ARRL saved back one set for ARISS's fund-raiser. AMSAT-NA, another ARISS sponsor, provided parts of the auction infrastructure. ARISS is thankful for all of its great sponsors and supporters! If auctions aren't your thing, please contribute a donation to ARISS-look for the Donate button near the top right corner of www.ariss.org page or email k1sto(a)arrl.org. Thank you!

International Space Station Astronauts are Calling CQ Students ARISS-US program’s education proposal window is open April 1 - May 15, 2019 March 24, 2019: The Amateur Radio on the International Space Station (ARISS) program is seeking proposals beginning April 1, 2019, from US schools, museums, science centers and community youth organizations (working individually or together) to host radio contacts with an orbiting crew member aboard the International Space Station (ISS) between January 1, 2020 and June 30, 2020. Each year, ARISS provides tens of thousands of students with learning opportunities about space technologies, communications, and much more through the exploration of Amateur Radio and space. The ARISS program connects students to astronauts on the ISS through a partnership between NASA, the Radio Amateur Satellite Corporation, the American Radio Relay League, other Amateur Radio global organizations and the worldwide space agencies. The program’s goal is to inspire students to pursue interests and careers in science, technology, engineering, and mathematics (STEM) and in Amateur Radio. Educators report regularly that student participation in the ARISS program stimulates interest in STEM subjects and STEM careers. One educator wrote, “Many of the middle school students who took part in and attended the ARISS contact have selected science courses in high school as a result of that contact.” Educators are setting up ham radio clubs in schools and learning centers because of students’ interest. ARISS is looking for organizations that will draw large numbers of participants and integrate the contact into a well-developed, exciting education plan. Students can learn about satellite communications, wireless technology, science research conducted on the ISS, radio science, and other STEM subjects. Students learn to use Amateur Radio to talk directly to an astronaut and ask their STEM-related questions. ARISS will help educational organizations locate Amateur Radio groups who can assist with equipment for a once-in-a-lifetime opportunity for students. The proposal window opens April 1, 2019 and the proposal deadline is May 15, 2019.
