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: https://www cubesat org/cds-announcement

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

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
