Two-Minute Engineering Video Update Available
Jerry Buxton, N0JY, Vice President-Engineering has published a two-
minute video update on the progress of AMSAT projects. Among the
highlights are:
- The RadFxSat-2 / Fox-1E satellite is ready for delivery and
integration and is expected to launch by the end of the year.
- The University of Maine will use an AMSAT LTM-1 module for command
and control of their upcoming CubeSat mission, MESAT-1. The LTM-1
also provides a linear transponder for amateur radio use. AMSAT is
in discussions with additional partners about flying LTM-1 modules.
- Due to the COVID-19 pandemic, vendors have been delayed in
supplying printed circuit boards for the GOLF-TEE project. The
impact of the pandemic has also affected the amount of time
AMSAT's volunteer engineers have for their hobby work. Completion
of GOLF-TEE is expected by the end of June 2021.
- Dependent on fulfilling its primary mission, the GOLF-TEE satellite
may include a X-band downlink parrot of the V-band uplink and L/S
band uplinks which are planned for GOLF-1.
- Research is underway to place GOLF-1 into a higher orbit while
meeting regulatory requirements.
- GOLF-TEE is a candidate for a launch on an upcoming DoD mission.

CubeSat.org Announced CubeSat Design Specification Rev.14
The Cal Poly CubeSat Lab has announced that a draft version of the
newest CubeSat Design Specification (CDS) is available. Feedback
before the official release of the 14th revision is welcome.
There are a number of changes, which are detailed in the Appendix of
the document. But overall, the document has been updated to act as
more of a guide for CubeSat designers, rather than a “how-to” manual.
The original CDS introduced the CubeSat Standard to the world almost
two decades ago. It defined the physical and electrical
characteristics for a 1U and 3U size CubeSat and included
requirements for interfacing with the only CubeSat dispenser
available at the time, the Poly-Pico Orbital Deployer (P-POD). Since
then the industry has expanded to include more standard sizes and
additional dispensers with more available options.
To accommodate these new advancements, the CDS has been retooled to
be more flexible and inclusive of developments within the industry.
Requirements that were originally written specifically for the P-POD
will encompass requirements for all dispensers currently available.
It is also the intention for the new revision of the CDS to identify
the available options on dispensers that are widely available for
use. Currently that list is limited to dispensers that publish their
specifications online, but can be updated as dispenser companies make
that information available to us. The CDS will also define all U
configurations in one document with one set of requirements for ease
of reference.
The new CDS should be the first stop for any developer beginning
their CubeSat design.

US Department of Defense to Share 3450 – 3550 MHz with 5G
Commercial Operations
The FCC will auction sharing rights to the upper 50 MHz of the
3300 – 3500 MHz secondary amateur radio allocation to commercial 5G
interests in the wake of the Department of Defense (DoD) agreement to
share spectrum at 3450 – 3550 MHz. The entire band currently supports
a variety of military operations, and amateur radio has a long
history of peaceful coexistence with the Department of Defense as a
secondary user of this spectrum.
Late last year, the FCC proposed to delete the amateur secondary
3300 – 3500 MHz secondary allocation as well as the amateur-satellite
allocation at 3400 – 3410 MHz. The FCC could auction the 100 MHz of
spectrum in early 2022. This latest move makes a contiguous band of
spectrum from 3450 – 3980 MHz available for commercial 5G networks.
“For a number of years, the National Telecommunications and
Information Administration (NTIA) and FCC have focused on the
3450 – 3550 MHz band as the spectrum most conducive to sharing with
commercial users,” said ARRL Washington Counsel David Siddall, K3ZJ.
“Monday’s statements announced that a framework for sharing has been
worked out.”
In December 2019, the FCC adopted a Notice of Proposed Rulemaking
(NPRM) in WT Docket 19-348 proposing to delete the 3300 – 3500 MHz
secondary amateur band. ARRL strongly opposed the move in its
comments on the NPRM, which put forward the FCC’s plans to remove
“existing non-federal secondary radiolocation and amateur
allocations” in the 3300 – 3500 MHz band and to consider options for
relocating incumbent non-federal operations.
Siddall said the spectrum below 3450 MHz presents a more difficult
government/commercial sharing scenario, and that future sharing
there remains uncertain. “We continue to argue that the amateur
secondary allocation should not be deleted in this band,” he said.
“We recognize that our access is secondary, and ask only to be given
a chance to use our considerable technical skills to work around
whatever future uses may be implemented in this spectrum.”

Chinese Mars probe Tianwen-1 successfully received by AMSAT-DL
Soon after its launch on July 23rd, the Chinese Mars mission
Tianwen-1 has been received by AMSAT-DL with its 20m ground station
in Bochum, Germany. Amateur radio observers Paul Marsh M0EYT and his
#hearsat group have been tracking Tianwen-1 since its launch from
Wenchang Spacecraft Launch Site. As no trajectory data was published
Daniel Estevez, EA4GPZ used the coordinated observations to generate
an estimated trajectory which allows narrowing down the search area.
After some reformatting of the data by James Miller G3RUH, AMSAT-DL
gave it a first try during on July 24th and 25th with successful
detection of the Tianwen-1 telemetry on 8430.911 MHz. An initial
guess suggests a BPSK modulation with residual carrier and data
modulated on a subcarrier. More than 2 GB of baseband data have been
recorded and are being analyzed by the #hearsat group.
This report not only demonstrates the capabilities of Amateur Radio
operators when it comes to deep space missions but also the
flexibility and performance of the AMSAT-DL 20m ground station in
Bochum which (except for scheduled maintenance on site) can be
operated fully remotely.

SmallSat 2020 Virtual Conference Proceedings Available Online
The 34th Annual Small Satellite Conference was a virtual event hosted
by SmallSat.org and Utah State University, Logan, Utah. The event
attracted 8,100 participants over three days August 1-3, 2020. With
the conference theme, "Space Mission Architectures - Infinite
Possibilities", the conference explored the realm of possible space
mission architectures and how they can be practically achieved to
support the diverse needs of the global space community.
Organized along twelve technical tracks, all 162 presentations are
available to the public. Additionally, literally hundreds of posters
can be downloaded for viewing. Especially useful is a search function
on the site that can search keywords to help find presentation and
posters that deal with specific topics.
For those interested in the future of small satellites, including
those in the Amateur Radio Satellite Service, there is one especially
pertinent presentation entitled " Small Satellite Regulation in 2020"
with attorneys Lynne Montgomery and Christopher Bair of Wilkinson
Barker Knauer LLP. In this twelve minute presentation,
Ms. Montgomery thoroughly covers the range of regulations affecting
small satellite operations, the agencies involved, licensing
procedures and what future legal burdens are looming for small
satellite operators.
The complete collection of presentations and posters can be seen at:
