ARISS - Amateur Radio on the International Space Station - Amateur Radio societies and AMSAT organisations from the ISS partner countries, in the USA, Canada, Russia, Europe and Japan, have set up ARISS - Amateur Radio on the International Space Station. It is a volunteering working group devoted to develop and put into operation the onboard Amateur Radio station. A major objective of ARISS is to increase students' interest through the medium of amateur radio in art, mathematics and science (STEAM studies).
To provide 10 minutes of HamVideo reception, a chain of ground stations located along the pass of the ISS footprint, is needed. In Europe, the following stations participate to this chain: For descending passes: EI9FHB, Cork, Ireland F6DZP, Poitiers, France IK1SLD, Casale Monferrato, northern Italy IZ7EVR, southern Italy (not operational) On the world map, one …
Noise Power Measuring Tool Jean-Pierre Courjaud F6DZP wrote software to facilitate antenna setup. The Noise Power Measuring tool (NPM) can be used to measure the sun noise on S-band. A special version of Orbitron/whispDDE sends commands to the azimuth and elevation motors, providing offsets from minus 10° to plus 10° from the sun coordinates. The …
Jean-Pierre Courjaud F6DZP wrote dedicated software for the reception of HamVideo signals. The Tutioune 1600 software commands the TT S2-1600 PCI card and handles the transport stream. In ISS mode it also adds the missing DVB tables. The program not only delivers video and audio, but also provides technical parameters such as RF power and …
Since 2014, ground stations have used the Techno Trend TT S2-1600 PCI card for reception of the DATV signals transmitted by the HamVideo transmitter. This card is not produced anymore, but some are offered for purchase on Ebay. The TT S2-1600 PCI card comprises: a zero tuner a QPSK DVB-S demodulator a Transport Stream to …
HamTV Status After repairs and reinstall on the ISS, HamTV is now in a testing phase. Various test are being performed before HamTV can be integrated into ARISS contacts. The HamVideo DATV transmitter has stopped working April 2018. Provisions were that, in such a case, the transmitter should be discarded and disposed of as waste. …
The HamVideo power levels in the table at the bottom of this page result from worst case computations, intended for the evaluation of system efficiency. See Link budget computation by I0KPT. As shown in fig 2, the ISS orbits at about 400km above the surface of the earth. That is the distance between the ISS …

22 October 2016, Gaston Bertels, ON4WF, talked in Ostrów Wielkopolski, Poland at the 6th Polish-wide Conference of Contributors and Sympathizes of ARISS about “ARISS milestones”. It was a excellent time for many people (there was above 100 persons), especially teachers and pupils, who never heard about the HAM radio! More information about the event can be found …

During the ITU World Radiocommunication Conference 2015 (WRC-15) to be held from 2nd to November 27th 2015, an ARISS contact was realized on Tuesday, November 3rd, 2015. Students from Institut Florimont were able to use the ITU station to talk to astronauts Kjell Lindgren KO5MOS (in front) and Kimiya Yui KG5BPH (in QSO with 4U1WRC), who …
