ARISS HamTV Minitiouner
Following the successful inaugural use of HamTV during ARISS Scheduled Contacts in the UK with ESA Astronaut Tim Peake, there has been much interest in radio amateurs establishing their own HamTV station. Jean-Pierre Courjaud, F6DZP, designer and implementer of the successful Tutioune series of software created a new USB connected DATV decoder and related software …
European chained HamTV ground stations
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 Measurement tool (NPM)
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 …
Tutioune 1600 receiving software
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 …
HamTV reception with TT S2-1600 PCI card
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 Home Page
HamTV Status 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. ARISS succeeded in having the HamVideo transmitter downmassed by a SpaceX vehicle. The parcel was recovered after splashdown in the Pacific and delivered to NASA (Houston). The …
HamTV Power Levels
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 …
