    "content": "Dear friends,\n\nThis is an update about our satellite URESAT-1, launched with SpaceX on\nJune 12th (Transporter-8 mission from Vanderberg) and using Alba Orbital as\nour space broker. First of all, URESAT-1 is a small pocketQube 1.5P (8x5x5\ncm), much smaller than a Cubesat.\n\nThe satellite was expelled from the D-Orbit Orbital Transfer Vehicle (OTV)\nION ten days after the launch, on June 22th at 12.10 UTC, along with\nMRC-100 and ROM-2 satellites. Soon after, using the OTV TLE available for\npointing, signals from MRC-100 and ROM-2 were received but not ours... This\nmade us think we again had a problem with the deployment of the antennas.\n\nFortunately Daniel EA4GPZ could receive the URESAT-1 on June 26th using the\nATA radio telescope at 22.03 UTC. The pattern of the transmissions matched\nand, using the IQs from the two antennas used, with two polarities, we\ncould decodify telemetry, showing that the satellite was performing well\nwith no resets or events. The battery was almost fully charged but the\nantennas were not deployed, as it was shown in the status packet received.\nWe worked hard to improve the deployment system from our previous\nsatellites but something hasn't gone well again. Satellite seems to be cold\neven in sunlight but we performed tests using temperatures as low as 20 C\nbelow zero so this should not be a problem...\n\nDoing a lot of analysis (after the ATA observation we found that our\nsatellite was 20-30 seconds ahead of MRC-100)  and with a lot of help from\nthe Satnogs thread regarding that launch, we managed to conclude that our\nsatellite should be NORAD object 56992.\n\nThe team at Dwingeloo radio telescope on Netherlands has confirmed this\nwith several observations these days\n\nhttps://network.satnogs.org/observations/7877553/\nhttps://network.satnogs.org/observations/7881183/\nhttps://network.satnogs.org/observations/7883687/\n\nUsing the IQs of these recordings (available here\nhttps://data.camras.nl/satnogs/) we have been able to decode new telemetry,\nCW and even a SSTV image from the satellite image bank. After more than\nthree weeks in orbit the satellite is performing well and we hope that the\nantennas will deploy at some moment.\n\nThe plan now is sending the satellite commands to try to deploy\nthe antennas, although we are going to need a lot of power because the\nreceived signal without a proper antenna will be low. If you have a\npowerful station for transmitting on VHF and want to help us, please let me\nknow.\n\nWe want to thank Daniel EA4GPZ, the ATA radio telescope, PE0SAT, the\nDwingeloo staff, especially Tammo Jan, and Satnogs staff for their kind\nhelp in identifying the URESAT and the reception of their signals. It has\nprovided very valuable data on the status of the satellite.\n\nDecoded telemetry, CW and the SSTV image is available in our web (sorry, it\nis in spanish) and also in the Satnogs thread about the Transporter-8\nmission:\n\nhttps://www.amsat-ea.org/\nhttps://community.libre.space/t/spacex-f9-transporter-8-2023-06-12-21-35-utc/10499\n\n73\n\nFelix EA4GQS - AMSAT EA President\n\n\n",
