GreenCube is Now Designated Italy-OSCAR 117 (IO-117)

On July 13, 2022, the GreenCube satellite was launched on a Vega-C launch vehicle from the Centre Spatial Guyanais in Kourou, French Guiana. The satellite project is managed by the S5Lab research team at Sapienza University of Rome, and involves ENEA (the Italian National Agency for New Technologies, Energy and Sustainable Economic Development) and University of Naples. The satellite carries environmental and thruster payloads and as well as a 70cm digipeater for amateur radio use.

At the request of the GreenCube teams, AMSAT hereby designates the satellite as Italy-OSCAR 117 (IO-117). We congratulate all the involved teams, thank them for their contribution to the amateur satellite community, and wish them continued success on this and future projects.

The IO-117 (GreenCube) Club Continues to Grow

Because of the increasing interest and the quick appearance of instructional material on making digipeated contacts through IO-117, the “GreenCube User Club” has rapidly grown to more than 300 as reported by Doug Papay, K8DP. Several individuals have blogs describing their operational set up that enables them to take advantage of the great DXCC and VUCC opportunity:

Burt DeMarcq, FG8OJ, offers some nicely detailed instructions and good advice on his blog at: .

Fabio Roccatagliata, F5VKV, writes on the AMSAT-BB mailing group that the UZ7HO Soundmodem is very useful for IO-117 but one must download http://uz7.ho.ua/greentnc.zip for success as the tone spacing is shifted from those normal for APRS. He continues: “Use the ssb modem, 1600 main frequency in the spectrum. (Put the) Radio in USB, AGC off if possible (or fast), no noise blanker/reduction. You should receive the packet when the signal is within the bandwidth bar you see in the sound modem spectrum. Adapt the DCD threshold accordingly, usually by the half. In the green cube GUI window you should see the decoded packets, in the sound modem the data.” Editor Note: The link to the zipped file is listed directly because it does not yet appear on Andrey Kopanchuk’s website).

Joe Pereira, VK5EI, suggested on the AMSAT-BB mailing group that the summary by Tom Van den Bon, ZR6TG, is particularly helpful for newcomers. It may be found in a blog post on Tom’s website: .

Doug Papay sent a Friday update (which is growing rapidly) on the number and DXCC distribution of contacts made on the bird:

As of 1400Z 2/Dec/2022 there have been 303 stations active on IO-117 since 31/Oct/2022. Congratulations to ZL3TKZ for contact #300!

There have been 154 stations heard in the last 24 hours. There have been 194 unique grid squares and 51 DXCC entities activated. Here is the DXCC list including number of stations heard from each country:

Dhruva Space- Thybolt Mission, Amateur Radio Payload Information

Dhruva Space launched the Thybolt Mission On 26 November, 2022, at 11:56 am, onboard ISRO PSLV-C54. The Thybolt Mission consists of two 0.5U nano satellites. These nanosatellites are built on the 0.5U P-DoT satellite platform which is designed, built and tested by Dhruva Space for use in the amateur communications, disaster management, and low bit-rate applications of STEM and strategic importance. The qualification of this 0.5U platform with its sub-systems will enable many more amateurs across India to learn, build, launch and operate experiments on amateur satellite missions.

Information regarding the system and the the data modes they use may be found at the Dhruva Space website: While it is not clear whether the satellites will be active throughout their entire orbital pathThe website states: “Please note that S&F Messaging will be available after conclusion of launch & early phase and commissioning operations tentatively on 20 December, 2022.”

Nico Janssen, PA0DLO writes on the AMSAT-BB list:
“Doppler measurements show that Thybolt 1 and 2 are the objects 54363 and 54364. Current separation: 1 s, so it is not yet possible to determine which is which.
CW beacon frequencies: Thybolt 1: 435.35447 MHz and Thybolt 2: 435.3522 MHz.
Nothing received on the telemetry frequency 436.175 MHz, but that downlink is probably only active when in range of India.”

Hamfests, Conventions, Maker Faires, and Other Events

AMSAT Ambassadors provide presentations, demonstrate communicating through amateur satellites, and host information tables at club meetings, hamfests, conventions, maker faires, and other events.

Don’t forget to check in to the AMSAT-Twitter Meetup Net on DMR BrandMeister Talkgroup #98006 | D-STAR Reflector REFSAT | YSF Reflector #11689 | Wednesday Nights @ 21:00 CST.

AMSAT Ambassador Clint Bradford K6LCS has a few satellite presentations scheduled:
-The PAPA System in Southern California
-Greenville, North Carolina
-Ontario, Canada
-Thames Valley, England

Think a 90-minute lively, informative, and fun “How to Work the Easy Satellites” Zoom presentation would be appropriate for your convention or club? Always included are overviews of the ARRL, AMSAT, and ARISS. And pre-presentation questions are welcome.

Satellite Shorts From All Over

+ A new AMSAT distance record has been claimed on FO-29. KE9AJ in DM79IQ48UR worked EB1AO in IN52PE28F at a distance of 7,642 km on 23-Nov-2022 at 20:46 UTC, edging out the previous record held by KG5CCI and F4DXV by 8 km. See https://www.amsat.org/satellite-distance-records/ for all records. [ANS thanks Paul Stoetzer, N8HM, AMSAT Executive Vice President & Ambassador for the above information.]

+ Artemis I’s launch tower and deluge systems performed as designed. The tower sustained some minor damage, particularly to the elevator (blew the doors off), which will be repaired before the next launch.[ANS thanks The Orbital Index for the above information.]

+ OMOTENASHI indeed was unable to be commanded to perform a landing burn. Its operators hope that it has a stable spin axis and that enough sunlight will reach it in the spring to establish comms and undertake secondary mission objectives. [ANS thanks The Orbital Index for the above information.]

+ Eutelsat Communications (Euronext Paris: ETL) (Paris:ETL) has selected Thales Alenia Space (Thales 67 % and Leonardo 33 %) to build a next-generation highly flexible, software-defined satellite (SDS). The Flexsat (for flexible satellite) will be based on Thales Alenia Space’s cutting-edge ‘Space Inspire’ (INstant SPace In-orbit REconfiguration) product line, enabling seamless reconfiguration and instant in-orbit adjustment to offer an optimum level of customer service, maximising the effective use of the satellite resources.
