Proposal Submitted to ESA for Geostationary Microwave Amateur Payload
A proposal has been submitted to the European Space Agency (ESA) by
AMSAT-UK, the British Amateur Television Club (BATC), and AMSAT-NA, with
input from members of the UK Microwave Group for a geostationary microwave
amateur payload with planned coverage of at least part of North America.
This proposal was submitted in response to a presentation at the AMSAT-UK
Colloquium from Frank Zeppenfeldt, PD0AP, of ESA, who has secured €250,000
in funding to investigate the possibility of an amateur satellite or
payload in geostationary orbit.
The proposal notes the desire for coverage of all ESA member and
cooperating states, but that it is not possible for a satellite in
geostationary orbit to cover the entirety of this territory, which ranges
from Cyprus at approximately 34 degrees east to western Canada at
approximately 141 degrees west and lays out example coverage from three
slots: 5 degrees west, 30 degrees west, and 47 degrees west. In a later
section, the proposal also discusses two non-geostationary orbit options
that could provide the desired coverage: a tundra orbit and a high earth
orbit just below the geostationary belt.
The amateur radio and educational payload proposed consists of two 5.6 GHz
uplink and 10 GHz downlink transponders (Mode C/x) - one 250 kHz wide with
20 watts of output for narrowband modes such as SSB, CW, and narrowband
digital mdoes and one 1 MHz wide with 20 watts of output for wideband
modes, including amateur television. The transponder design would include
an optional SDR block for signal regeneration. Additionally, a 24 GHz
receiver would also function as a transponder uplink. The proposal also
calls for a 47 or 74 GHz multimode beacon or additional downlink
transmitter, an earth-pointing camera with a still image downlink as part
of the telemetry or beacon for educational outreach, and a red or
near-infrared laser experiment aimed towards Western Europe. All downlink
signals would be phase coherent with timing by GPS reference or a
chip-scale atomic clock.

ARISS Celebrates 40th Anniversary of Owen Garriott's STS-9 Operation
ARISS has been celebrating the 40th anniversary of the first ham in space.
On November 28, 1983, the Space Shuttle Columbia lifted off with Owen
Garriott, W5LFL. Onboard was a specially customized Motorola MX-340 two
meter handheld radio and an antenna that attached to the shuttle's window.
Shortly before crossing the west coast on December 1, 1983, Columbia
executed a roll manuever that exposed the antenna toward earth and W5LFL
began to call CQ. At 02:38 UTC, Lance Collister, WA1JXN, in Frenchtown, MT
answered his CQ and made the first amateur radio QSO with a human in space.
A rush of QSOs followed over the next several days before Columbia returned
to Earth on December 8th. Among the amateur operators in the log were
Senator Barry Goldwater, K7UGA, and King Hussein of Jordan, JY1.
Videos including QSOs from orbit have been posted to the ARISS YouTube page
at https://www.youtube.com/@ARISSlive/videos
On December 7th, ARISS hosted a webinar with Owen's son, Richard Garriott,
W5KWQ, who later operated the amateur radio station aboard the
International Space Station. An archived video of the webinar can be found
at https://www.youtube.com/watch?v=Ys0Jjn40Y_A
During the webinar, ARISS International Chair Frank Bauer, KA3HDO,
announced that Richard Garriott would be the keynote speaker at ARISS's
40th anniversary celebration event in February 2024. Details for this event
can be found at https://www.ariss.org/overview.html
Additionally, in celebration of the STS-9 mission, ARISS teams worldwide
have come together to prepare an SSTV event.
SSTV from the ISS will be sent on 145.800 MHz using the PD120 format.
Transmissions are scheduled to begin on December 16th at 10:15 UTC and end
on December 19th at around 18:00 UTC.
Melissa Gaskill, a science author from Austin, Texas, has written a
comprehensive review about the 40-year history of amateur radio in space.
In her article, "Ham Radio in Space: Engaging with Students Worldwide for
40 Years," Gaskill explores the Shuttle Amateur Radio Experiment (SAREX),
which is now known as Amateur Radio on the International Space Station
(ARISS). The article can be found at
https://www.nasa.gov/missions/station/iss-research/ham-radio-in-space-engaging-with-students-worldwide-for-40-years/
Gaskill said that while she wrote the article, she is not an expert on
thesubject but there are many who are including Kenneth Ransom, N5VHO,
International Space Station (ISS) Ham Project Coordinator since 2004.
Ransom said that amateur radio in space was a possibility even before 1983,
when Astronaut Owen Garriott, W5LFL (SK), made history during the STS-9
Space Shuttle Columbia mission with the first amateur radio contact from
space. NASA had been looking for ways to bring amateur radio to Skylab (a
space station designed as an orbiting workshop for scientific research) and
even the moon.

AMSAT Publishes 2022 Financial Review and IRS Form 990
AMSAT has posted its IRS Form 990 and 2022 Financial Review on the AMSAT
website at https://www.amsat.org/audit-and-other-financial-reports/
AMSAT publishes its financial statements as reviewed by an independent
accountant as part of its commitment to transparency regarding its
financial status with its membership and donors.
In 2022, AMSAT had total revenue of $306,801 and total expenses of
$129,261. As of December 31, 2022, AMSAT reported net assets totaling
$1,494,470.
In the decade between 2012 and 2022, AMSAT's reserves increased by nearly
250% while designing, constructing, and launching five Fox-1 satellites and
working on several other projects, including GOLF, Fox Plus, the Linear
Transponder Module, and the AMSAT CubeSatSim.
AMSAT thanks its membership and donors for their generous support over the
years. Keeping amateur radio in space is an endeavor that requires
significant financial resources. Despite the currently healthy status of
AMSAT's finances, spending on hardware acquisitions for construction of
GOLF and Fox Plus is expected to ramp up over the coming year, so please
consider a donation if you are able.
AMSAT is a 501(c)(3) non-profit organization, so your contributions may be
tax deductible. If you need to make a Required Minimum Distribution from a
retirement account by the end of the year, please also consider making a
donation to AMSAT from your RMD. Donations may be made at
https://www.amsat.org/donate/
AMSAT also needs donations of time from interested volunteers with both
technical and non-technical skills. Please visit

Changes to AMSAT-NA TLE Distribution for December 7, 2023
Two Line Elements or TLEs, often referred to as Keplerian elements or keps
in the amateur community, are the inputs to the SGP4 standard mathematical
model of spacecraft orbits used by most amateur tracking programs. Weekly
updates are completely adequate for most amateur satellites. TLE bulletin
files are updated Thursday evenings around 2300 UTC, or more frequently if
new high interest satellites are launched. More information may be found at
https://www.amsat.org/keplerian-elements-resources/
HADES-D may not be correctly associated with its object number; use TLEs
with caution.
The following satellites have been added to this week's AMSAT-NA TLE
distribution:
EIRSAT-1 NORAD Cat ID 58472 IARU coordinated downlink on 437.100 MHz
ENSO NORAD Cat ID 58470 IARU coordinated downlink on 436.500 MHz and beacon
at 14.099 MHz
The following satellites have been removed from this week's AMSAT-NA TLE
distribution:
CTIM NORAD Cat ID 52950 Decayed from orbit on or about 4 December 2023
Move-IIb NORAD Cat ID 44398 Decayed from orbit on or about 4 December 2023

Comments on making general contacts
I have been seeing a lot of traffic on Facebook and I suspect on other
social media sites with people asking why they are not hearing the crew
make general contacts. First off the crew is very busy on the ISS and they
simply may not have the time to just pick up the microphone and talk.
Also, one needs to be aware of their normal daily schedule. I have listed
below the constraints that we at ARISS have to follow in order to schedule
the school contacts. Hopefully this will help you better schedule your
opportunities.
Typical daily schedule
Wakeup to Workday start= 1.5 hours
Workday start to Workday end=12 hours
Workday end to Sleep= 2 hours
Sleep to wakeup= 8.5 hours
The crew's usual waking period is 0730 - 1930 UTC. The most common times to
find a crew member making casual periods are about one hour after waking
and before sleeping, when they have personal time. They're usually free
most of the weekend, as well.
SSTV events are not that often. So please check out https://www.ariss.org/
for the latest information or watch for the ARISS announcements.
And don’t forget that the packet system is active.
As always, if there is an EVA, a docking, or an undocking; the ARISS radios
are turned off as part of the safety protocol.

Hamfests, Conventions, Maker Faires, and Other Events
AMSAT Ambassadors provide presentations, demonstrate communicating through
amateur satellites, and host information tables at club meetings, hamfests,
conventions, maker faires, and other events.
AMSAT Ambassador Clint Bradford, K6LCS, says,
"Think a 75-minute presentation on "working the easy satellites" would be
appropriate for your club or event? Let me know by emailing me at
k6lcsclint (at) gmail (dot) com or calling me at 909-999-SATS (7287)!"
Clint has NEVER given the exact same show twice: EACH of the 150+
presentations so far has been customized/tailored to their audiences.

Satellite Shorts From All Over
+ EB1AO reports the successful telecommand of AMSAT Spain's HADES-D
satellite. A test of the FM transponder is expected to follow.
+ The Russian resupply mission to the International Spacee Station,
Progress MS-25, launched on Dec. 1 and then had to be manually docked due
to issues with its automated rendezvous system. Cosmonauts Oleg Kononenko,
RN3DX, and Nikolai Chub, monitoring the approach from the station's Zvezda
module, took over by remote control at the direction of Russian flight
controllers and deftly guided the vehicle in for docking early on Dec. 3.

+ Hubble temporarily took a break from science operations while NASA
investigates faulty readings from one of its gyroscopes, just as the
telescope hit 30 years on from STS-61, the mission that corrected its
optics and brought the iconic space telescope to full operation. On
December 8th, Hubble returned to science operations with all three of its
gyroscopes operational and the spacecraft healthy. (ANS thanks The Orbital
Index and NASA for the above information)
+ With moderate coronal mass ejections (CMEs) inbound and our Sun heading
into its solar maximum faster than anticipated, it’s an excellent time to
watch for auroras. However, the Space Weather Prediction Center of the
National Oceanic and Atmospheric Administration (NOAA) warns that the
geomagnetic storms pose risks of increased atmospheric drag and other risks
for Low Earth Orbit (LEO) satellites. (ANS thanks The Orbital Index and
