Life to get more difficult for US Cubesat operators.
by Joseph B. Fitzgerald 09 Sep '22

09 Sep '22

The FCC wants to "adopt a five-year rule, which would require space station operators planning disposal through uncontrolled re-entry into Earth’s atmosphere to complete disposal as soon as practicable, and no more than five years following the end of mission." see https://docs.fcc.gov/public/attachments/DOC-387024A1.pdf No exemption for us hams operating under Part 97 of the FCC rules either, although waivers for certain research and scientific missions may be granted. de KM1P

Re: New fast dsstv mode for amateur satellites.
by Sasha Tim 09 Sep '22

09 Sep '22

Thank you very much everyone! I am touched by the enthusiasm :) Due to the many replies I think First of all, I2OIM, thank you for the interest! KF4HR, thank you, also, for your interest. To boost interest in the mode I think I might make a challenge of who can make the most QSOs within, say, 30 days :) Would anyone be interested once the app comes out? AA4KN, Unfortunately I don't have any videos, since right now the state of the software is a jumbled mess, not unlike goestools (sorry pietern ;)), although goestools is nowhere near as messy as mine. Once it's all patched up I'll release videos of it in operation. AB6KX, would you have the link to the group? I'm very interested in this. Also freedv is the best! G3VZV, my respect for the FunCube project is immense. I have received a lot of telemetry, and the bpsk mode is simply fantastic. The only thing is that it doesn't carry a camera, but I assume the next one will (given by your email)? OK2PNQ, it was me on librespace who tried to receive PSAT-2 😊 Also, my respect for the project is immense. By the way, do you know when (or if) PSAT-3 will launch? PSAT is an exciting mission for me! As for the timetables, I haven't timed it on larger images but I can say that a good-sized (640x320) image can be transmitted without compression in about 50-80 seconds, depending on the level of error correction used. Thank you very much for everyone's replies and enthusiasm!! Also, may I take the time to complain that DSP is hard ;) Sasha On Thu, Sep 8, 2022 at 3:49 AM Tomáš Urbanec <tommypnq(a)centrum.cz> wrote: > Hi Sasha, > we are group which designed camera with SSTV downlink on PSAT-2.

New fast dsstv mode for amateur satellites.
by Sasha Tim 08 Sep '22

08 Sep '22

Hello everyone, This is my first time posting here, so please do reprehend me in case I break a few guidelines. For the last few months, I have been developing a new digital slow scan television mode for amateur satellites. The focus is to still be able to recover a complete image at reasonable speeds. In fact, current tests show that if 100% data recovery is desired, then up to 30% data loss can happen. If resolution is sacrificed, there can be up to 80% loss and still be able to recover the entire image, unlike sstv and other scanline systems. Also, a noise free image (100% recovery) can be received down to about 10dB SNR. Would some of you be interested in this mode? It’s halfway thru development, and if there is enough interest I will post code on GitHub and this bulletin once it’s finished. Thank you, Sasha T

LOTW VUCC Satellite entries
by Mike Swiatkowski 08 Sep '22

08 Sep '22

I'm having trouble getting my satellite log to show up in the LOTW VUCC Satellite section. I have over a hundred grids and not one shows up confirmed in LOTW. I looked at the .adi log in TSQL and indeed the mode of satellite, satellite name, and bands are populated. Does anyone have an idea why nothing would show up in VUCC Satellite? I only see my 6m contacts. I even tried to set a filter as my grid square from the example online (https://lotw.arrl.org/lotw-help/vucc-setup/?lang=en). That didn't help. Your assistance is appreciated. Thanks, Mike, AA9VI

Two hams turn us on to a pair of tracking tools. Brian Wilkins, KO4AQF, brings our attention to AROW: During Artemis I, Orion will travel to 40,000 miles beyond the Moon in the first integrated flight test with the Space Launch System (SLS) rocket. Using AROW, almost anyone with internet access can pinpoint where Orion is and track its distance from the Earth, distance from the Moon, mission duration, and more. AROW is available on NASA’s website and on the @NASA_Orion Twitter account. AROW visualizes data collected by sensors on Orion and sent to the Mission Control Center at NASA’s Johnson Space Center in Houston during its flight. It will provide periodic real-time data beginning about one minute after liftoff through separation of the SLS rocket’s Interim Cryogenic Propulsion Stage approximately two hours into flight. Once Orion is flying on its own, AROW will provide constant real-time information. On the web, users can follow AROW to see where Orion is in relation to the Earth and the Moon and follow Orion’s path during the mission. Users can view key mission milestones, and characteristics on the Moon, including information about landing sites from the Apollo program. Also available for download will be trajectory data from the flight, called an ephemeris. AROW also will provide a set of Orion’s state vectors — data that describes precisely where Orion is located in space and how it moves — for inclusion in these tweets once Orion is flying on its own. These vectors can be used for data lovers, artists, and creatives to make their own tracking app, data visualization, or anything else they envision.

These satellites are a great way to interest young people in satellite communications. They transmit a powerful signal so that they are easily received an inexpensive radio, a simple antenna and free software. Currently there are three operational polar orbiting NOAA weather satellites that transmit image data in the APT format at 137 MHz. When one of these satellites pass overhead, it is possible to use an RTL-SDR with appropriate antenna and software to automatically receive the satellite weather images they transmit. The purpose of this guide is to completely install software and configure them to automatically receive incoming NOAA signals and process them into images. While there are many variations of hardware that can be used for this application, Yanz focuses on a simple setup to get anyone on the air. Samual's guide focuses on the software and shows how to setup Virtual Audio Cable for piping audio between programs, SDR# for receiving the signal, Orbitron for tracking the satellite and WXtoIMG for decoding the image.

However, Galaxy 15 continues to drift out of its geostationary orbit slot at 133 degrees West, and "will soon begin transiting through orbital locations licensed for other satellites," an Intelsat spokesperson said. "With the payload muted, the focus of this coordination ensures 'fly-by' procedures are coordinated so that the spacecraft avoid a physical collision. This is a normal part of spacecraft operations that is regularly executed and poses minimal risk." Intelsat said it has successfully moved all customers from Galaxy 15 to its Galaxy 23 satellite. SpaceX is slated to launch Galaxy 33, Galaxy 15's replacement, "on or about Oct. 8, 2022," the spokesperson added. [ANS thanks SpaceNews for the above information.] + But sometimes, things just work: Engineers with NASA have repaired an issue with the space agency's Voyager 1 spacecraft, but have yet to identify the cause of the problem, officials confirmed on August 27. The probe had been sending garbled data about its status, including information about its health and activities to mission controllers, despite otherwise operating normally. Launched in 1977, NASA's Voyager 1 and Voyager 2 probes are both still active, exploring deep space. Both are still communicating with NASA, despite being launched 45 years ago. The spacecraft are two of only five space probes from Earth that have left the solar system. Voyager 1 is currently 14.5 billion miles from Earth. [ANS thanks SpaceDaily for the above information.] + NASA and Axiom Space said Wednesday, August 28 that they plan to launch a second private astronaut mission to the International Space Station in 2023. The spaceflight, coordinated by the U.S. space agency and the private Houston-based infrastructure developer, will be designated as Axiom Mission 2, or Ax-2 and will launch from NASA's Kennedy Space Center in Florida in the second quarter of 2023. Private Axiom astronauts will travel to the ISS and spend 10 days aboard the space station and participate in in-orbit activities in coordination with ISS crew and flight controllers on the ground. The first Axiom mission, in April 2022, featured extensive amateur radio activity. No word yet about hams aboard Ax-2.

Tracking Artemis-1
by David G0MRF 03 Sep '22

03 Sep '22

Does anyone know how to track Artemis 1 during the next few days.? Tracking the moon is fairly straightforward, but trying to locate the cubesat signals on 70cm during the flight there probably needs some dedicated tracking software. Maybe some resource online? 73 David G0MRF
