The Interoperable Radio System (IORS), ARISS’ next generation radio system successfully completed a battery of stressful tests required as part of the final certification of the hardware for launch to and operation on the International Space Station.

Amateur Radio on the International Space Station (ARISS) logoDuring the week of July 8, the IORS, consisting of the JVC Kenwood D-710GA Radio and the AMSAT developed Multi-Voltage Power Supply, successfully completed a series of Electro-magnetic Interference (EMI)/Electro-Magnetic Compatibility (EMC) tests to ensure that the ARISS hardware will not interfere with the ISS systems or other payloads. Testing continued into the following week, where the IORS successfully passed power quality and acoustics testing. These tests verified that the ARISS IORS will not introduce harmful signals back into the ISS power system and is quiet enough to meet ISS acoustic requirements. ARISS Hardware Team members Lou McFadin, W5DID and Kerry Banke, N6IZW were at the NASA Johnson Space Center supporting this two week battery of tests in concert with the NASA test and certification team.

Kerry Banke states, “Since the IORS is being qualified to operate on 120VDC, 28VDC and Russian 28VDC as well as transmitting on VHF or UHF, a lot of test combinations were required to cover all cases. Each input voltage type was also tested at low, medium and high line voltage. Moreover, additional permutations were required to test the IORS under no load, medium load and full load at each voltage level. So it should not be surprising why the tests took two weeks to complete.”

Successful completion of these tests represents a key milestone in preparing the IORS for launch. ARISS can now begin final assembly of the flight safety certification in preparation for launch. ARISS is working towards launch ready status by the end of the year.

ARISS Russia is planning Slow Scan Television (SSTV) image transmissions on 145.800 MHz FM from the International Space Station.

Below is the scheduled for the planned activation of SSTV from the ISS. The first session is the routine MAI-75 activity that is only active for a few orbits. It appears that the most of the world (except N. America) will get a shot during the two day run. Some lucky operators along the east coast of North America should get a pass on July 29.

Inter-MAI-75 activity
(July 29) GMT 210/13:15 – SSTV activate
(July 29) GMT 210/21:25 – SSTV power down

(July 30) GMT 211/13:50 – SSTV power up
(July 30) GMT 211/19:30 – SSTV shutdown

ARISS plans to celebrate the life and accomplishments of astronaut, scientist and ham radio pioneer Owen Garriott with a commemorative SSTV event featuring images from Garriott’s work with ham radio during his missions in space. This event is currently scheduled to begin on August 1 at 09:40 GMT and ends at 18:15 GMT on August 4.

Transmissions will be sent at 145.800 MHz FM in the SSTV mode PD-120. Once received, images can be posted and viewed by the public at http://www.spaceflightsoftware.com/ARISS_SSTV/index.php and you can receive a special SSTV ARISS Award for posting your image. See https://ariss.pzk.org.pl/sstv/ for details.

This event uses a computer in the ISS Russian Segment, which stores images that are then transmitted to Earth using the ARISS amateur radio station located in the Service Module which employs the Kenwood TM D710E transceiver.

Please note that SSTV events are dependent on other activities, schedules and crew responsibilities on the ISS and subject to change at any time. You can check for updates regarding planned operation at:

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: NASA, Russian Space Agency, ESA, JAXA, and CSA. The US Center for the Advancement of Science in Space (CASIS) and the National Aeronautics and Space Administration (NASA) provide ARISS special support.

ARISS offers an opportunity for students to experience the excitement of Amateur Radio by talking directly with crew members on board the International Space Station. Teachers, parents and communities see, first hand, how Amateur Radio and crew members on ISS can energize youngsters’ interest in science, technology, and learning.

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.

50 students in Rajkot, India enjoyed a live demonstration of Slow Scan Television (SSTV) from the International Space Station during a visible pass of the ISS.

Russian cosmonauts on the ISS transmitted amateur radio SSTV on 145.800 MHz FM from April 11-14.

AMSAT-INDIA Regional Coordinator West India Zone Rajesh Vagadia VU2EXP reports:

To spread awareness of Amateur Radio, Satellites & ARISS activities in the region we conducted interesting event recently.

On April 12, 2019 we openly invited students & citizen of Rajkot – Gujarat to be present & witness SSTV Live Demonstration, that too during Visible pass of ISS from terrace of my home.

More than 50 students & citizens assembled to my QTH by 18:30 IST (13:00z). We gave printed ISS tracking chart/ISS crew details to all of them, and explained how to use chart.

Myself Rajesh Vagadia VU2EXP gave brief talk on Amateur Radio, ISS, OSCAR Satellites, Life of Astronauts, ARISS SSTV event, Student Outreach Program etc for one hour. Small display of radio stuff were also kept. Everybody get excited to learn such new things (for them) happening in Ham Radio world.

Good Visible ISS Pass of -3.0 magnitude with elevation of 36° was targeted for Live Demo, calculated for my Grid ML52jh.

With my 3 ele Yagi, VHF HT & recording device we started to track ISS at 19:27 IST (13:57z). Within a minute ISS started to appear from NNW direction moving towards SE. Students were requested to control their excitement & to keep silence as we were also recording audio. Soon sstv signal also get heard on 145.800 MHz. SSTV signal for two images were received & recorded.

It was exciting experience for all to sighting ISS at the same time getting signals from it, felt like having handshake with ISS crew! After pass, we amplified weak audio in Audacity & decoded two images (though bit noisy) with MMSSTV. Decoded Images were shared with all students as souvenir. It proved great learning experience for all. Had lots of Q&A till late and enjoyed light refreshments at end of the program.

As everything was arranged at our home I need to thanks my XYL Kiran, harmonic Snehal VU3WHO, brother Prakash VU3PLJ & nephew Priyesh VU3GLY for extending helping hands.

Btw, leading newspaper Divyabhakshar supported this radio experiment & published good articles (though in regional language Gujarati), see
