Usage of the amateur radio band requires that\nsatellite operators release all their telemetry formats. This allows\ninterested amateurs to be able to have a go at decoding telemetry, and\nallows projects like SatNOGS to help collect telemetry using the huge\nnetworks of volunteer ground-stations.\n\nIn particular I would be very interested to decode the SSDV data.\n\nAlso, it looks like this frequency was not coordinated with the IARU - or\nat least it's not showing up on the IARU coordination list (\nhttp://www.amsatuk.me.uk/iaru/finished.php ).\n\n73\nMark VK5QI\n\nOn Fri, Mar 19, 2021 at 5:12 AM Tanan Rangseeprom <[email protected]> wrote:\n\n> BCCSAT-1 is an educational multi-spectral Cubesat 1U developed by the\n> cooperation between Bangkok Christian College and the King’s Mongkut\n> university of technology north Bangkok. http://bccsat.bcc.ac.th/\n>\n> Schedule When our cubesat is completely finished it will be launched into\n> space in March 20,2021 06.07 AM UTC at Russia with the Soyuz-2.1 rocket by\n> UNISAT-7 GAUSS SRL to the low earth orbit at 575 km.\n> http://en.roscosmos.ru/21973/ and https://www.roscosmos.ru/30285/\n>\n> BCCSAT-1\n> 1 99999U 21999A 21079.53571058 -.00000058 00000-0 00000+0 0 06\n> 2 99999 098.4012 345.1641 0004344 283.2593 155.6823 14.80364805 03\n>\n> Downlink Frequency\n> Beacon 435.635 MHz CW https://www.youtube.com/watch?v=hPpSTEf3PUI\n> Slow Scan Digital Video SSDV Data 435.635 MHz AFSK 1.2 kbps\n> Telemetry Data 435.635 MHz GMSK 9.6 kbps\n>\n> After launch into space if AMSAT member receives the CW signal of BCCSAT-1\n> satellite. please send information to our team directly an email to:\n> [email protected]\n>\n> BCCSAT-1 is a technology demonstration satellite in Thailand.
