Chubusat Message Exchange Service?
by Tony 10 Feb '16

10 Feb '16

All: Does anyone know the details on how Chubusat's Message Exchange Service works? It appears the satellite will receive messages on the 1200 baud VHF uplink while the 9600 baud UHF down link will be used to send (possibly broadcast) said messages. According to the website, ground stations need to "send an inquiry message" to read messages. That said, if this is a full-duplex system, one would obviously need a pair of modems to run both 1200 and 9600 baud i.e., something like a pair of UZ7HO sound modems. Any thoughts? Tony -K2MO

QRU WinLNK transmitting every 2 secs to the ISS?
by Stewart Todd Morgan 10 Feb '16

I saw your message to the AMSAT board about this, and I think it is documented (somewhat) on your page in the Winlink Text-Messaging section under Message Alerts: http://www.aprs.org/aprs-messaging.html I wasn't sure if you were just trying to be subtle. 73 Todd AL0I

QRU WinLNK transmitting every 2 secs to the ISS?
by Robert Bruninga 09 Feb '16

09 Feb '16

Noticed that N3FCX seems to be transmitting every 2 seconds to the ISS…. “QRU WNLINK” or something. We are demonstrating satellite tracking to the students this week and we see this signal on there at this high data rate on most passes. Is this winlink something automatic? Bob

Upcoming ARISS contact with Royal Masonic School for Girls, Rickmansworth, UK
by n4csitwo＠bellsouth.net 09 Feb '16

09 Feb '16

An International Space Station school contact has been planned with participants at Royal Masonic School for Girls, Rickmansworth, UK on 11 Feb. The event is scheduled to begin at approximately 18:09 UTC. The duration of the contact is approximately 9 minutes and 30 seconds. The contact will be direct between GB1SS and GB1RMS. The contact should be audible over the UK 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. The Royal Masonic School for Girls is an independent girl's day and boarding school in Rickmansworth, Hertfordshire, with an exceptional, unusual and distinguished history. Founded in 1788 with the purpose of educating the daughters of Freemasons who were unable to support their families, it is one of the oldest girls' schools in the country. We attract girls aged 4-18 from across Hertfordshire, Buckinghamshire and North London and boarders from all over the world. We also have a Pre School for boys and girls aged 2 to 4. Our ethos is both an inspirational and nurturing and our girls strive to be the very best they can be, academically, morally and creatively. Our public examination results are consistently impressive and each year around 90% of girls leave RMS to take up places at University. Life at RMS is centered on much more than "just" academic success and the School is well known for its exceptional pastoral care, and the wealth of extra-curricular opportunities it offers - including Astronomy as we are one of very few schools in the UK to have our own planetarium and observatory! 1. If you have hiccups in space do you bounce around? 2. I watched your video on water and why it turned into a sphere. Would you get the same reaction with a fizzy drink like lemonade? 3. I'm 7 years old - when I am your age, what do you think space travel will look like? 4. We have heard you had to breathe o2 before your brilliant spacewalk. Are there any precautions you had to take after returning inside the ISS? 5. What was the first word that came into your head when you saw the Earth from Space? 6. What was the hardest thing to adjust to when you arrived at the ISS? 7. Which of your muscles has been affected the most by the zero gravity? 8. Who was your biggest inspiration to travel into space? 9. How is being an astronaut different from being an aquanaut, apart from the sea and the air? 10. What is the best advice that you have been given and wish to pass on to future astronauts before travelling to the ISS?? 11. Your blog says that you are doing research into new space age metals using a levitation furnace. Why is zero gravity better for this type of experiment? 12. Aside from plants, how do you produce oxygen on the ISS? 13. What is the difference between flying a helicopter and being in a rocket going to the ISS? 14. Did your training prepare you for the actual experience of space jet lag given you have said you adjusted so quickly? 15. How is the ISS helping us deal with the challenges of deep space voyages? 16. Is there an 'up' on the space station when conducting a spacewalk for navigational /orientating purposes? 17. What is your favourite experiment that you have carried out in space, and why? 18. What has been the most surprising everyday object on the ISS that you did not expect to find? 19. How often do you see Solar wind? 20. When Chris Hadfield recently visited us he said your guitar skills were good but needed more practice Do you have time to practice the guitar in space?

We can be found at Amateur Radio on the International Space Station (ARISS). To receive our Twitter updates, follow @ARISS_status Next planned event(s): TBD ABOUT ARISS Amateur Radio on the International Space Station (ARISS) is a cooperative venture of international amateur radio societies and the space agencies that support the International Space Station (ISS). In the United States, sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American Radio Relay League (ARRL), and the National Aeronautics and Space Administration (NASA). The primary goal of ARISS is to promote exploration of science, technology, engineering, and mathematics (STEM) topics by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students in classrooms or informal education venues. With the help of experienced amateur radio volunteers, ISS crews speak directly with large audiences in a variety of public forums. Before and during these radio contacts, students, teachers, parents, and communities learn about space, space technologies, and amateur radio.

Chubusat question
by Mark Lunday 09 Feb '16

09 Feb '16

Under the information for Chubusat 2 it says: <QUOTE> ChubuSat-2 provides the message exchange service. After the on-orbit checkout of the satellite, you can use the service, sending your message with amateur VHF (145.815MHz FSK 1200bps) then your message is written to the on-board memory. Anyone can read your message with amateur UHF (437.1MHz GMSK 9600bps) by sending inquiry message. The uplink/downlink format will be available in this page. <END QUOTE> I understand the 145.815 1200 bps FSK - this is the same as for NO-44, NO-84 and ISS. But what is GMSK 9600? How is that decoded? And how does one request a 'message read' on this cubesat? Mark Lunday, WD4ELG Greensboro, NC FM06be wd4elg(a)arrl.net http://wd4elg.blogspot.com

Re: [amsat-bb] AO-7 & FO-29 Low passes over Spain, big sole over USA
by Juan Antonio 08 Feb '16

08 Feb '16

The return from the SAT was strong until it was in the 90 deg azimuth, with 0.4deg elevation, because of the polarity change, then I could not copy it. I could copy N4IQV calling me, but we could not end the QSO. If some North/Central/South American station can work my grid IM78 in low elevation passes of AO-07 & FO-29, PSE Let me know for a sked.
