Consultation on Amateur Satellite Service – Your input needed

Satellite / nanosatellite project managers often wish to use amateur radio frequencies for educational and outreach purposes. The amateur radio community thus offers them a tremendous potential for monitoring their fragile conception. They often ask what kind of amateur radio experience would be interesting onboard a CubeSat or what services they could provide with their communications systems. The answer can be simple: a transponder, but these designers would like to bring novelty and innovation.

In order to provide more factual input, AMSAT-F has decided to launch an English Language Online Survey to find out what you do and would like to do as a satellite activity, what you expect from satellite designers and what you can bring to them. *The synthesis of these results will be presented at the second* AMSAT-F meetings « Rencontre spatiale radioamateur » on March 9 and 10, 2019 in Nanterre (France).

Do not hesitate, give your opinion by completing the questionnaire via the link : https://framaforms.org/amsat-francophone-survey-1548716436

The survey is in English but hosted on French server. Few guideline could be in French.

ARISS/NOTA ISS Slow Scan TV Event Feb 8-10

ISS SSTV image received by John Brier KG4AKV October 27, 2018

ARISS is planning another of their popular Slow Scan Television (SSTV) experiment events. International Space Station (ISS) transmissions are scheduled to begin Friday, Feb. 8 at 18:25 UTC and run through Sunday, Feb. 10 at 18:30 UTC on 145.800 MHz FM with the SSTV mode likely to be PD120.

SSTV operations is a process by which images are sent from the International Space Station (ISS) via ham radio and received by ham operators, shortwave listeners and other radio enthusiasts on Earth, similar to pictures shared on cell phones using twitter or instagram.

When this event becomes active, SSTV images will be transmitted from the ISS at the frequency of 145.800 MHz using the SSTV mode of PD120 and can be received using ham radio equipment as simple as a 2 meter handheld radio or a common shortwave or scanner receiver the covers the 2 meter ham band. After connecting the audio output of the radio receiver to the audio input of a computer running free software such as MMSSTV, the SSTV images can be displayed.

Transmissions will consist of eight NASA On The Air (NOTA) images (see https://nasaontheair.wordpress.com/). In additional, four ARISS commemorative images will also be included.

Once received, Images can be posted and viewed by the public at http://www.spaceflightsoftware.com/ARISS_SSTV/index.php In addition, you can receive a special SSTV ARISS Award for posting your image. Once the event begins, see details at https://ariss.pzk.org.pl/sstv/

Please note that the event is dependent on other activities, schedules and crew responsibilities on the ISS and are subject to change at any time. Please check for news and the most current information on the ARISS Twitter feed @ARISS_status or the AMSAT Bulletin Board

You can receive the pictures from the ISS by using the MMSSTV software and an Online Radio (WebSDR). Select a Frequency of 145800.0 kHz and Mode FM:
• Farnham WebSDR when ISS in range of London http://farnham-sdr.com/
• R4UAB WebSDR when ISS is over Russia http://websdr.r4uab.ru/
