BuzzSat Satellite Meteorology Course Now Available
The AMSAT Youth Initiative is pleased to introduce the first in its series of “Satellites in Space Help Us Live a Better Life on Earth” online courses!
Title screen from the Satellite Meteorology online course (Image: AMSAT)
An “Introduction to Satellite Meteorology” explores the many ways that NOAA satellites help meteorologists predict the immediate weather and long-term climate behavior to make our lives more enjoyable and safer. It is designed for students Grades 8-12.
Each chapter has 40-50 pages and is expected to take perhaps 30 minutes per chapter. If you leave the course, it will remember where you left off so you won’t have to start from scratch.
The course is designed to be “self-standing” so any student, parent, youth leader or teacher can independently utilize the course. The courses are free. You can try this course at:
Please note that this edition of the course is a beta release. Numerous improvements to the navigation features, clarity of graphics and technical content are scheduled for the next release in June 2025. But we’d love to hear from you! Please send your comments and suggestions to Frank Karnauskas, AMSAT VP-Development at f.karnauskas [at] amsat [dot] org.
Future course to be added later this year include how satellites play a critical role in managing:
- Climate Change
- Pollution Control
- Wildlife and Natural Resources
- Navigation
- Satellite Design and Operation
- Space Exploration
- Communications
- Broadcasting
- Military Operations
- And much, much more!
Subject matter experts in any of these areas or educators in the sciences are invited to talk with the BuzzSat team about future course development.

AMSAT Volunteers Power Hamvention Exhibit
AMSAT volunteers kept busy at the organization’s exhibit at the 2025 Dayton Hamvention. Interest level was high among both satellite veterans and hams just wanting information on how to get started on the satellites.
The hot seller at the exhibit was the brand new, updated edition of the book, Getting Started in Amateur Satellites.

The Hamvention AMSAT Forum was held on Saturday afternoon, May 17. The forum featured updates on the organization itself from AMSAT President Robert Bankston, KE4AL, Executive VP Paul Stoetzer, N8HM, and from Frank Karnauskas, N1UW, VP-Development. Frank also updated those in attendance on the AMSAT Youth Initiative, including the “Satellites in Space Help Us Live a Better Life on Earth” online courses (see above).
Jerry Buxton, NØJY, VP-Engineering, provided an overview of upcoming satellite projects and launches in development and Drew Glasbrenner, KO4MA, VP-Operations, discussed efforts to extend the lives of satellites already on orbit.
Prior to the beginning of the Hamvention, on Thursday evening, May 15, AMSAT members and friends gathered at Ticket’s Pub & Eatery in nearby Fairborn, Ohio for what has become a traditional gathering in recent years. More than 40 were in attendance — a record number for this event.

The 16th Annual TAPR/AMSAT Banquet Enjoyed by Many
The 16th annual TAPR/AMSAT Banquet was held at the Kohler Presidential Banquet Center on Friday, May 16. This dinner is always a highlight of the TAPR (Tucson Amateur Packet Radio) and AMSAT (Radio Amateur Satellite Corp.) activities during the Dayton Hamvention. This year’s banquet speaker was Phil Karn, KA9Q, who highlighted developments and use cases for his ka9q-radio software suite for SDR receivers.

Karn was the recipient of the ARRL’s Mary Hobart, K1MMH, Medal of Distinction. He was presented the honor at the ARRL donor reception on May 15, 2025, at the National Museum of the United States Air Force on Wright-Patterson Air Force Base near Dayton, Ohio.
A graduate of Cornell University and Carnegie Mellon University with degrees in Electrical and Computer Engineering, Karn has retired from a technology career including Bell Labs, Bellcore, and Qualcomm. He is co-founder of AMPRnet, is founder and past-President of Amateur Radio Digital Communications (ARDC), a private foundation that exists to support amateur radio and digital communication science and technology through grants and scholarships, and the management of 44Net. Karn continues to serve on the ARDC Board of Directors. The work of ARDC has contributed approximately $30 million to amateur radio since 2020.
Karn has been licensed since he was 15. “It’s been a major factor in my life, directly and indirectly,” he said. Karn views amateur radio as a creative outlet. “I’m an engineer, so I need an outlet for my technical ideas. I’m retired, so amateur radio now fulfills that need. It’s very gratifying to see others using your ideas and works,” said Karn.
Karn’s technical contributions to advance the Amateur Radio Service drive his dedication to the future of education through ham radio. He envisions education having a greater role in amateur radio in decades to come. “Ham radio has always excelled at individual self-learning, but it could do so much more. I’d really like to see the many technical tinkerers outside ham radio join us. I’d like to see much more amateur radio in formal education. HamSCI and the many university small satellite groups are good examples but there could be so much more. Hams will continue to create new technology, usually by working in academia and industry but also as individuals,” he said.
Mary Hobart, K1MMH, was ARRL’s first Chief Development Officer. She passed away in 2021. The medal named in her honor is given to those individuals or couples who have inspired our small community to reach higher with their own philanthropic support of ARRL and amateur radio. In 2023, ARRL honored Michael “Mike” D. Valentine, W8MM (Silent Key), and his wife Margaret “Peg” Valentine with the inaugural Hobart Medal.

JAMSAT Symposium 2025: Satellites, Soldering, and Socials in Tokyo
The Japan Amateur Satellite Association (JAMSAT) successfully hosted its 17th annual general meeting and technical symposium on March 22–23, 2025, at the National Museum of Emerging Science and Innovation (Miraikan) in Tokyo. The two-day hybrid event welcomed both in-person and online participants and featured a diverse program of organizational updates, technical presentations, hands-on outreach activities, and social networking opportunities for the amateur satellite community.
The general meeting, held on the first day at noon, covered official business including approval of the 2024 fiscal report, auditor’s findings, the 2025 project plan, and a proposed revision to the association’s bylaws. JAMSAT members were invited to vote by proxy or attend via Zoom, and participation exceeded expectations. The event was formally recognized as an international meeting, qualifying for discounted use of the Miraikan venue and underscoring its educational and public-service role.
Immediately after the meeting, the two-day symposium began with a series of technical presentations. Topics included the RST (Lehman Satellite Tracker) by JI1SYC, a report on the ultra-compact RSP-03 “Hamorun” satellite, and a briefing on QO-100 operations from Cambodia under the XU7AMO callsign. Other featured talks explored a geostationary payload proposal by AMSAT-DL, the SHF beacon’s status, and technical insights into the Ten-Koh 2 receiver system for 5.8 GHz.

Satellite mission updates were also prominent. Researchers from Chiba Institute of Technology presented results from the SAKURA satellite and previewed its successor, BOTAN. The team from Tokyo Institute of Technology introduced OrigamiSat-2, a CubeSat designed to test a two-layer deployable membrane antenna and high-speed downlink. The final session discussed amateur satellite roles in emergency communications, drawing attention to disaster readiness as a future focus area.
Public outreach remained a strong component of the event. On the morning of March 22, JAMSAT organized the “Touching Satellites” program with support from Icom Inc., offering live satellite demonstrations and electronics workshops for children. An exhibit area featured satellite engineering models and educational posters, while 10 young participants had the opportunity to assemble and solder simple kits under the guidance of volunteers.
A formal dinner was held at the nearby Chinese restaurant Tōen in Telecom Center, drawing a wide cross-section of members for informal conversation and project discussion. The social gathering reflected a return to normalcy following years of pandemic-related restrictions and helped to strengthen the group’s community bonds. JAMSAT plans to publish digital versions of the symposium materials online and encourages continued member engagement through web meetings, field activities, and international coordination.

Changes to AMSAT-NA TLE Distribution for May 16
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 daily in the first hour of the UTC day. New bulletin files will be posted immediately after reliable elements become available for new amateur satellites. More information may be found at https://www.amsat.org/keplerian-elements-resources/.
This week there are no additions or deletions to the AMSAT TLE distribution.

Satellite Shorts From All Over
+ Congratulations to Benni Riethmueller, DL4BEN, (age 16!) on receiving AMSAT Rover Award #087! To earn the AMSAT Rover Award, participants must accumulate a combined total of 25 points through various achievements in portable satellite operations outside their home grid square. The AMSAT Rover Award was established to recognize and honor the accomplishments of satellite operators who engage in rover operations. Rover operations involve the activation of grid squares outside one’s home grid, utilizing various satellite transponders and modes to establish communication links. A breakdown of the points system along with a list of past AMSAT Rover Award recipients can be found at https://www.amsat.org/amsat-rover-award/. Keep on roving, Benni, and continue to inspire others in the AMSAT community! (ANS thanks Bruce Paige, KK5DO, AMSAT Director of Contests and Awards for the above information)
+ China has granted scientists from six countries, including the United States, access to Moon rocks collected by its Chang’e-5 mission in 2020. Two NASA-funded U.S. institutions—Brown University and Stony Brook University—were selected to study the samples, despite longstanding restrictions on NASA’s direct collaboration with China. The China National Space Administration (CNSA) called the samples “a shared treasure for all humanity” and emphasized its commitment to international cooperation. Experts noted that while U.S.-China space technology exchanges remain limited, lunar sample analysis poses no military concern and aligns with global scientific norms. The Chang’e-5 samples are of particular interest because they appear to be about a billion years younger than those collected during the Apollo missions. CNSA officials stated they intend to maintain an active and open stance in global space collaboration through initiatives like the Belt and Road space information corridor.

+ The FAA granted environmental approval for up to 25 Starship launches a year at Starbase, a five-fold increase from the previous limit. (ANS thanks The Orbital Index for the above information.)
+ Due to budget cuts, NASA might scale back ISS operations, such as reducing crew size, extending crew missions, and halting upgrades to science instruments. A list of other NASA projects that may be abandoned by budget cuts is at https://www.planetary.org/articles/billions-wasted-mysteries-unsolved-the-missions-nasa-may-be-forced-to-abandon (ANS thanks The Planetary Society for the above information.)
+ Germany’s armed forces are planning to establish a large satellite constellation, aiming to create an independent communications infrastructure similar to SpaceX’s Starlink. The initiative, led by the Bundeswehr, envisions deploying hundreds of satellites to ensure secure and resilient military communications, with potential expansion into remote sensing and other applications. Germany has historically relied on satellite services provided by allies but shifting geopolitical dynamics have prompted a reevaluation of this dependence. The proposed Bundeswehr constellation is intended to ensure sovereignty and continuity in defense operations, even in contested or degraded environments. It would operate separately from IRIS2, the European Union’s own sovereign satellite project aimed at providing broadband internet across the continent.
