    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.

    A complete copy of the revised specification can be seen at:

    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.”

    QSO Today Virtual Expo Satellite Presentations Still Available

    Congratulations to Tom Schuessler, N5HYP of Irving, Texas for his

    outstanding presentation, "Getting Started with Amateur Radio

    Satellites." Tom's thirty-three minute presentation provided an

    excellent review of the basics needed to enjoy this aspect of the

    hobby, on-the-air-demonstrations, and prominent promotion of AMSAT

    as the center of Amateur Radio Satellite activity.

    Also presented at the Virtual Expo was 4Z1ZV, Zvi Segal's overview of
    the Qatar Oscar-100 Satellite running seventeen minutes.

    Watch the presentations at https://qsotoday.vfairs.com/. Even if you

    didn't register for the original event, you can still register to

    watch the presentations which will be available until

    September 9, 2020.

    With over 14,000 participants each day of the August event,

    organizers are already the next QSO Today Virtual Expo for

    March 13-14, 2021.

    [ANS thanks QSO Today for the above information.]


    AMSAT's GOLF Program is about getting back to higher orbits, and it
    all begins with GOLF-TEE - a technology demonstrator for deployable
    solar panels, propulsion, and attitude control. Come along for the
    ride. The journey will be worth it!



    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: https://smallsat.org/.
