ARISS Opportunity for Educators

Clint Bradford
 

Message to US Educators Amateur Radio on the International Space Station contact opportunity
Call for proposals

New Proposal Window is October 1, 2020 to November 24, 2020

The Amateur Radio on the International Space Station (ARISS) Program is seeking formal and informal education institutions and organizations, individually or working together, to host an Amateur Radio contact with a crew member on board the ISS. ARISS anticipates that the contact would be held between July 1, 2021 and December 30, 2021. Crew scheduling and ISS orbits will determine the exact contact dates. To maximize these radio contact opportunities, ARISS is looking for organizations that will draw large numbers of participants and integrate the contact into a well-developed education plan.

The deadline to submit a proposal is November 24 th, 2020.   Proposal information and more details such as expectations, proposal guidelines and the proposal form can be found at  www.ariss.org . An ARISS Introductory Webinar session will be held on October 8, 2020 at 8 PM ET.  The Eventbrite link to sign up is:  https://ariss-proposal-webinar-fall-2020.eventbrite.com  

The Opportunity

Crew members aboard the International Space Station will participate in scheduled Amateur Radio contacts. These radio contacts are approximately 10 minutes in length and allow students to interact with the astronauts through a question-and-answer session.

An ARISS contact is a voice-only communication opportunity via Amateur Radio between astronauts and cosmonauts aboard the space station and classrooms and communities. ARISS contacts afford education audiences the opportunity to learn firsthand from astronauts what it is like to live and work in space and to learn about space research conducted on the ISS. Students also will have an opportunity to learn about satellite communication, wireless technology, and radio science. Because of the nature of human spaceflight and the complexity of scheduling activities aboard the ISS, organizations must demonstrate flexibility to accommodate changes in dates and times of the radio contact.

Amateur Radio organizations around the world with the support of NASA and space agencies in Russia, Canada, Japan and Europe present educational organizations with this opportunity. The ham radio organizations’ volunteer efforts provide the equipment and operational support to enable communication between crew on the ISS and students around the world using Amateur Radio.

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), the ISS National Lab-Space Station Explorers, and NASA’s Space Communications and Navigation program. The primary goal of ARISS is to promote exploration of science, technology, engineering, the arts, and mathematics topics by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students. Before and during these radio contacts, students, educators, parents, and communities learn about space, space technologies, and amateur radio. For more information, see www.ariss.org .

Bummer! I was really looking forward to having three more FM birds (CAS-5A, CAS-7A, and CAS-7C).

Now the $5 question:

Is it coming from the Russian module (like in the past) or is it with the new Kenwood radio from the Columbus module?

Using and entering YOUR pass data for the ISS’ new crossband repeater is VERY useful - especially since it is turned OFF for ARISS events, and when missions approach/leave the ISS.

It will be turned off approx 0900 UTC this Monday to support an ARISS contact.

ISS Crossband Repeater - What a Month!

Clint Bradford
 

Just a thanks to ARISS Dave and Dave, Kenneth in Houston, Gordo and Chip in Orange 
County, CA, and to Marvelous Rosalie for ALL the work getting our new asset up and 
running and ham-tested!

AND - OF COURSE - THANKS to ALL the hams and their signal reports!

From the ARISS team -

This project of the InterOperable Radio System (IORS) was launched from Kennedy Space Center on March 6, 2020 on board the SpaceX CRS-20 resupply mission. It consists of a special, space-modified JVC Kenwood D710GA transceiver, an ARISS-developed multi-voltage power supply, and interconnecting cables. The design, development, fabrication, testing, and launch of the first IORS was an incredible five-year engineering achievement accomplished by the ARISS hardware volunteer team. It will enable new, exciting capabilities for ham radio operators, students, and the general public. Capabilities include a higher power radio, voice repeater, digital packet radio (APRS) capabilities and a Kenwood VC-H1 slow scan television (SSTV) system.
 
A second IORS undergoes flight certification and will be launched later for installation in the Russian Service module. This second system enables dual, simultaneous operations, (e.g., voice repeater and APRS packet), providing diverse opportunities for radio amateurs. It also provides on-orbit redundancy to ensure continuous operations in the event of an IORS component failure. 
 
Next-gen development efforts continue. For the IORS, parts are being procured and a total of ten systems are being fabricated to support flight, additional flight spares, ground testing and astronaut training. Follow-on next generation radio system elements include an L-band repeater uplink capability, currently in development, and a flight Raspberry-Pi, dubbed “ARISS-Pi,” that is just beginning the design phase. The ARISS-Pi promises operations autonomy and enhanced SSTV operations. 
 
ARISS is run almost entirely by volunteers, and with the help of generous contributions from ARISS sponsors and individuals. Donations to the ARISS program for next generation hardware developments, operations, education, and administration are welcome -- please go to https://www.ariss.org/donate.html to contribute to these efforts.

Re: Operating tips

David,

Yes, I do need to turn the squelch off. I thought it was weird that the Yaseu FT-71 was so quiet with the squelch "off". My baofeng did have the white noise. Somehow I was able to get a good recording of PO101 in the middle of the afternoon over the weekend even with the squelch on!

Turns out I just turned the "squelch threshold level" off. As a new ham I don't fully understand the difference between "squelch" and "squelch threshold level", but turning the "squelch" off will definitely help in my endeavors.

And thank you for the advice.

Arup-
One thing about your recording. Mine always has constant background hiss because my squelch is wide open. When you are working the sats, you should have your squelch wide open.

Hi All,

I've attached my recording of the ISS pass tonight at 22:39z with a max elevation of 57 degrees from FN01.

A few questions
1. Can anyone offer tips on how to work a "smoother" pass? As you'll notice if you listen to the recording I often can only hear the call or grid, but not both. As such I'm hesitant to key-up and attempt a contact. I do have the doppler shift programmed in to the memory. I start at 437.815 and go down to 437.785 by 0.005 MHZ and I try to follow the path of the pass using SatSat and the compass on my phone. 

2. Is the choppiness due to being in a mountainous area? Or are people "stepping" on each other?

Re: Operating tips

Off hours is definitely the key. I'm a night owl, so I concentrate on passes from 10pm - 1am. I've been able to make up to six contacts in a pass! During the day, I'm lucky to make one.

Thanks for the reassurance. I tried another working a pass on PO101 earlier today (18:25z) and had the same issue so I was beginning to think it was me. My recording of PO101 sounds similar.

You are doing nothing wrong! Just too many people all at once, and some without proper tone.


Try more “off-peak” hour passes ... More power is NOT the cure!

It will calm down ...

Got word earlier this afternoon from Houston that a recycling of the radio power took care of the problem.
Soon after that, I heard John, KG4AKV making QSOs and the system sounded good.
