[amsat-bb] Re: This weekends ISS Shadow-Beacon Plasma Experiment
Only just seen this, hadn't realised there was a Space Plasma experiment using the 145.825 MHz packet system http://knts.tsniimash.ru/Shadow/en/Overview.aspx I couldnt find the details about how they are going to capture data. Is it by Hams manually capturing files and then emailing them in? At first blush one would consider having all the APRS ground statis be IGates and send it all in, but that will not work, because the APRS Internet system (APRS-IS) filters out all dupes and only forwrds one copy. So when 20 statiosn receive the same thing (desired for this experiment) only one copy makes it through the internet. Maybe they have a different plan... But otherwise an interesting expriment.

I was just on 145.825 MHz for the 76 degree elevation pass over Chicago. I noticed some subjective observations I could describe as the downlink seemed weaker than usual for a portion of the pass. This dear reader will continue to try to determine what kind of signal report will be most helpful for the experiment. It sounds interesting and I already have the equipment set up. -- 73 de JoAnne K9JKM k9...@amsat.org ___ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author.

They explain it on their website.
