First Element of ARISS Next Generation (Next-Gen) Radio System Installed in ISS Columbus Module

September 2, 2020—The ARISS team is pleased to announce that set up and installation of the first element of our next generation radio system was completed and amateur radio operations with it are now underway. This first element, dubbed the InterOperable Radio System (IORS), was installed in the International Space Station Columbus module. The IORS replaces the Ericsson radio system and packet module that were originally certified for spaceflight on July 26, 2000.

Initial operation of the new radio system is in FM cross band repeater mode using an uplink frequency of 145.99 MHz with an access tone of 67 Hz and a downlink frequency of 437.800 MHz. System activation was first observed at 01:02 UTC on September 2. Special operations will continue to be announced.

The 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. 

ARISS–Celebrating 20 years of continuous amateur radio operations on the ISS!

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.

First Element of ARISS Next Generation Radio System Readied for Launch on SpaceX CRS-20

During this Holiday Season, when the spirit of giving and receiving gifts reigns high, ARISS received a special gift and delivered a phenomenal gift to the international community.  This occurred on Thursday December 19, 2019.

Our international gift to all—students, STEM education, the public and the amateur radio community—was the historic transfer of the first Interoperable Radio System (IORS) flight unit, serial number 1001, to NASA Johnson Space Center for launch on SpaceX CRS-20.  The special gift received by ARISS was the approval from NASA Safety to launch the IORS on SpaceX CRS-20 and stow the radio system on the International Space Station.  December 19, 2019 was truly a banner day for ARISS!

The IORS is a foundational element of the ARISS next generation radio system and is an incredible engineering achievement by the ARISS hardware team. This first element delivery will support easier radio mode transitions and enable new, exciting capabilities for hams, students and the general public.  The IORS will include a higher power radio, an enhanced voice repeater, updated digital packet radio (APRS) capabilities and slow scan television (SSTV) capabilities for both the US and Russian segments. The IORS consists of a special, modified JVCKenwood TM-D710GA transceiver, an AMSAT-developed multi voltage power supply and interconnecting cables.

This first flight IORS will be installed in the ISS Columbus module.  A second flight unit is expected to be launched sometime in 2020 for installation in the Russian Service module.  A total of 4 flight units and 10 total units will be built by the ARISS hardware team to support on-board flight operations, training, operations planning and hardware testing.  Future upgrades and enhancements to the next generation system are in various stages of design & development.  These include a repaired Ham Video system (currently planned for launch in mid-to-late 2020), L-band (uplink) repeater, ground command operations capability, LimeSDR signal reception, a microwave “Ham Communicator” and Lunar Gateway prototype experiment.

While yesterday was truly an historic milestone, it should be noted that there is still much “heavy lifting” work to be done to prepare the IORS for Operations on ISS.  ARISS has 92 engineering requirements and our operations Phase III safety review to complete.  The space agencies take a position of “Trust but Verify.”  Thus, these engineering and safety “verifications” all need to be closed out before the IORS can be unstowed and turned on.  This will be the ARISS hardware team’s focus over the next few months.

Also, please remember that ARISS is almost entirely run by volunteers.  So donations to the ARISS program for next generation hardware developments, operations, education and administrative functions are always welcome.  Please go to https://www.ariss.org/donate.html  if you want to contribute to our efforts!

In closing, ARISS would like to thank the outstanding contributions of the IORS hardware development team on an incredible radio system.  ARISS would like to thank our sponsors and donors for helping us realize the IORS hardware systems.  On behalf of the ARISS team, we would like to wish you all a joyful and prosperous Holiday Season—Merry Christmas, Happy Hanukkah, and Happy New Year!!

Ad Astra!  To the Stars!

ARISS Next Generation Radio System Completes Critical Flight Certification Tests

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.

IORS test bench

During 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 Centersupporting 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.
