We remind you that this module is also integrated into the YPSat\nmodule, which is fixed to the second stage of the launcher, so it will fall\nwith it. Their transmissions will be carried out during the ballistic\ntrajectory of the stage until re-entry.\n\nHere you can see a picture of the module:\nhttps://www.amsat-ea.org/s/cc_images/cache_18924688.jpg?t=1715005387\n\nAnd here another one of the module integrated in YPSat:\nhttps://www.amsat-ea.org/s/cc_images/teaserbox_18694860.jpg?t=1702228877\n\nThere are 2 types of transmissions that will be carried out:\n\n- FT8\n- SSTV Robot 36\n\nThe apparent radiated power of such transmissions is less than -8 dBm (75\nuW)\n\nFT8 transmissions are made every 16 seconds, while SSTV's are every 5\nminutes. The first transmission after power on is from SSTV.\n\nThe working frequencies are as follows:\n\n144.175 MHz FT8 Mode:\n\n- Callsign AO4ARI HO60 if the antenna has been deployed\n- Callsign AO4ARI HO61 if the antenna has not been deployed\n\n144.550 MHz SSTV Robot 36 mode with live image and 'Hades' text\n\nThese frequencies have been allowed by IARU due to the short duration of\nthe mission (hours) and the extremely low power.\n\nA carrier with a frequency of 144.550 MHz (same frequency as SSTV) is left\nbetween FT8 tones.\n\nAfter activation by the YPSat Wake Up module, powered by the Ariane-6,\nGENESIS-A waits 4860 seconds (81 minutes) before proceeding to deploy the\nantenna for 30 seconds, after which time transmissions begin.\n\nThe antenna deployment continues to be attempted every 10 minutes, without\nchecking.\n\nYou have this information compiled in PDF in the following document on the\nwebsite:\n\nhttps://www.amsat-ea.org/app/download/13458580/AMSAT+EA+-+GENESIS-A+transmissions+description.pdf\n\nWe are aware that it is going to be very difficult to receive something but\nhigher power was not allowed by Ariane as GENESIS-A will be transmitting at\nthe same time as the launcher stage.\n\n73,\n\nFélix EA4GQS\n\n\n", "attachments": [ { "email": "https://mailman.amsat.org/hyperkitty/api/list/[email protected]/email/42S3DJSTGMKIVUP537OSZEH3KLI6YURB/", "counter": 2, "name": "attachment.html", "content_type": "text/html", "encoding": "utf-8", "size": 2773, "download": "https://mailman.amsat.org/hyperkitty/list/[email protected]/message/42S3DJSTGMKIVUP537OSZEH3KLI6YURB/attachment/2/attachment.html" } ] }
