ARISS News Release No. 19-18 Dave Jordan, AA4KN ARISS PR aa4kn(a)amsat.org Dec. 24, 2019 SSTV Event Planned for Late December ARISS is planning an SSTV event featuring commemorative images. This event is currently scheduled to begin on December 28, 2019 at 11:00 UTC and ends at 18:20 UTC on January 1, 2020. Please make note that sometimes changes may occur in the crew work schedule that could affect our SSTV transmission dates and times, so frequently check our ARISS Facebook and Twitter accounts shown below for any updates before and throughout the event. Transmissions will be sent at 145.800 MHz FM in the SSTV mode PD-120. Once received, images can be posted and viewed by the public at http://www.spaceflightsoftware.com/ARISS_SSTV/index.php and you can receive a special SSTV ARISS Award for posting your image. See https://ariss.pzk.org.pl/sstv/ for details. Also for simplicity, we have added a new information tab for SSTV events, under the General Contacts pulldown menu at www.ariss.org . About ARISS: Amateur Radio on the International Space Station (ARISS) is a cooperative venture of international amateur radio societies and the space agencies that support the International Space Station (ISS). In the United States, sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American Radio Relay League (ARRL), the ISS National Lab and National Aeronautics and Space Administration (NASA). The primary goal of ARISS is to promote exploration of science, technology, engineering, and mathematics (STEM) topics by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students in classrooms or public forms. Before and during these radio contacts, students, educators, parents, and communities learn about space, space technologies, and amateur radio. For more information, see www.ariss.org.

CAS-6 Beacon?
by Hasan al-Basri 23 Dec '19

23 Dec '19

Has anyone from Stateside heard TLM from CAS-6? (not expecting xponder on, just want to hear its heartbeat) I see a couple isolated reports from other areas of the world. There was no signal on the 5 deg EL earlier pass, and now waiting for teh 10;57 a.m. 16:57z pass with an EL of 64 deg here in central USA 73, N0AN I'm guessing that even the beacon may not be on while out of range of China 73, N0AN Hasan

Re: [amsat-bb] ANS-353 AMSAT News Service Special Bulletin - SMOG-P and ATL-1 Designated Magyar-OSCAR 105 (MO-105) and Magyar- OSCAR 106 (MO-106)
by Peter Horvath 22 Dec '19

Hello, on this happy occasion I'd like to add some more info about MO-105 and MO-106, hoping that more people will be tune in and listen to the telemetry received from the satellites. SMOG-P (MO-105) is a 1p PocketQube (5x5x5 cm, 250 grams), a fully redundant tiny satellite with an actual scientific payload: a flying spectrum analyzer. It measures the scattered RF energy over the UHF band (specifically, in the digital terrestrial TV band) that can be detected in space. ATL-1 (MO-106) is a larger 2p PocketQube featuring the same spectrum analyzer experiment. Both satellites transmit almost identical telemetry data. In addition to basic CW telemetry carrying callsign, battery voltage and temperature, there is a digital telemetry with variable data rate and coding scheme. Most frequently, modulation is 1250 or 5000 bps GMSK. The data is encoded either by the well-known "AO-40" FEC, or a shorter, proprietary variant of it, but they can also use a more powerful, state-of-art repeat-accumulate (RA) coding scheme. Some practical information about receiving the telemetry: A GUI telemetry receiver is available for Windows and Linux (soon for OS X as well), and a command line receiver can also be used (Linux only). Both can be downloaded from https://gnd.bme.hu:8080/index The programs are able to submit the received packets to the central telemetry data base. This requires a quick registration, the login credentials can be used with either of the decoders. There are some issues with the GUI software that hopefully will be resolved within a few days. These decoders assume either a USB receiver connected through the sound card or an rtl-sdr receiver. Thanks to Daniel Estevez, EA4GPZ, a high quality, full decoder and packet uploader is also available for GNU Radio 3.8 within the out-of-tree module gr-satellites. For uploading to the received packets, it uses the same login as the "official" programs do: https://github.com/daniestevez/gr-satellites/tree/maint-3.8 This decoder can unleash the full potential of the RA FEC. You'll need to put an FM demodulator in front of the flowgraph. I'd be glad to see many submissions on the "Leaderboard" from around the world: https://gnd.bme.hu:8080/leaderboard Having many receiving stations around the globe could greatly improve the global picture the spectrum analyzer payload can offer. 73 Peter HA5CQA/AK4RP
