Newly Revised 2020 Digital Edition of “Getting Started with Amateur Satellites” Now Available
The 2020 edition of AMSAT's "Getting Started with Amateur Satellites" is now available on the AMSAT store. A perennial favorite, Getting Started is updated every year with the latest amateur satellite information, and is the premier primer of satellite operation. This definitive reference is written for the new satellite operator, but includes discussions for the experienced operator who wishes to review the features of amateur satellite communications. The new operator will be introduced to the basic concepts and terminology unique to this mode. Additionally, there are many practical tips and tricks to ensure making contacts, and to sound like an experienced satellite operator in the process. The book is presented in DRM-free PDF format, in full color, and covers all aspects of making your first contacts on a ham radio satellite.
Joining the cover art for the first time this year is a depiction of the next generation of AMSAT satellites - AMSAT's GOLF series of 3U CubeSats.

Amateur Radio on the International Space Station (ARISS) Team in the United States Creates a New Organization: ARISS-USA
In late May, the USA team of the ARISS International working group became an incorporated non-profit entity in the state of Maryland, officially becoming ARISS-USA. This move allows ARISS-USA to work as an independent organization, soliciting grants and donations. They will continue promoting amateur radio and STEAM—science, technology, engineering, arts, and math within educational organizations and inspire, engage and educate our next generation of space enthusiasts.
ARISS-USA will maintain its collaborative work with ARISS International as well as with US sponsors, partners, and interest groups. The main goal of ARISS-USA remains as connecting educational groups with opportunities to interact with astronauts aboard the International Space Station (ISS). ARISS-USA will expand its human spaceflight opportunities with the space agencies, beyond low Earth orbit, starting with lunar opportunities including the Lunar Gateway. ARISS-USA will continue to review and accept proposals for ISS contacts and expand its other educational opportunities to increase interest in space sciences and radio communications.
Becoming an independent organization has been discussed for quite some time. ARISS-USA lead Frank Bauer, KA3HDO said “The scope and reach of what ARISS accomplishes each year has grown significantly since its humble beginnings in 1996. Our working group status made it cumbersome to establish partnerships, sign agreements and solicit grants. These can only be done as an established organization.” Bauer further elaborated, “The ARISS-USA team remains deeply indebted to our working group partners—ARRL and AMSAT, who enabled the birth of ARISS—and our steadfast sponsors, NASA Space Communication and Navigation (SCaN) and the ISS National Lab (INL).” ARISS-USA aims to keep earning high regards from all these partners and sponsors.
While ARISS-USA is now an incorporated non-profit entity, we are in the process of applying for tax exemption as a Section 501(c)(3) charitable, scientific or educational organization. Until that status is approved by the USA Internal Revenue Service, donations made directly to ARISS-USA will not be tax deductible for taxpayers in the USA. Those wanting to make a tax deductible donation for the benefit of ARISS-USA can, in the meantime, continue to make donations to ARISS sponsor AMSAT-NA through the ARISS website at: www.ariss.org.
As ARISS-USA begins a new era as a human spaceflight amateur radio organization, it acknowledges those who were so instrumental in the formation of human spaceflight amateur radio. These include Vic Clark, W4KFC and Dave Sumner, K1ZZ from the ARRL; Bill Tynan, W3XO and Tom Clark, W3IO from AMSAT; Roy Neal, K6DUE a major guide for SAREX and ARISS; and NASA astronaut Owen Garriott, W5LFL. Also remembered is Pam Mountjoy, NASA education, who had the vision to develop the ARISS working group as a single amateur radio focus into the space agencies. All of these giants’ shoulders are what ARISS-USA rests upon.

AMSAT President's Statement on Creation of ARISS-USA
Announced June 5, 2020, ARISS-USA has been formed as a non-profit corporation to operate independently of The Radio Amateur Satellite Corporation (AMSAT). Since the formation of Amateur Radio on the International Space Station (ARISS) in the mid-1990s, AMSAT has been a consistent supplier of technical expertise, funding, and operational logistics. AMSAT will work with ARISS-USA to ensure a smooth transition for operations and funding.
Over the years, as the scope and activity of ARISS grew, AMSAT continued its financial backing in times of need, providing hundreds of thousands of dollars to fund projects and operations. Many of AMSAT’s members are an integral part of the ARISS team. The human spaceflight element of AMSAT’s vision has been realized through these contributions.
I offer my best wishes to ARISS-USA for a successful future.
73,
Clayton W5PFG AMSAT President

AO-73 Now in Full-Time Transponder Mode
After some eight months in continuous sunlight, AO-73 (FUNcube-1) has now started to see some eclipses during each orbit.
The telemetry received has shown that the spacecraft continued to function perfectly during this period and the on board temperatures did not reach excessively high levels.
After this became clear, our next concern was the battery. Having been kept fully charged for this period, would it actually hold a charge and do its job when in eclipse?
After three weeks of increasing eclipse periods we can now see that indeed the Li battery appears to be ok and the bus voltage has not yet dropped below 8.1 volts.
So today we have changed the operating mode from high power telemetry educational mode to continuous amateur mode with the transponder ON. The telemetry continues to be available, albeit at low power.
We will, of course, continue to carefully monitor the data but are planning to leave the spacecraft in this mode for at least the next week. Please enjoy using it!

-------------------------------------------------------------------- KG5FYJ Assigned to Upcoming ISS Mission
NASA has assigned astronaut Kate Rubins, KG5FYJ, to a six-month mis- sion to the International Space Station as a flight engineer and member of the Expedition 63/64 crew.
Rubins, along with cosmonauts Sergey Ryzhikov and Sergey Kud-Sverchkov of the Russian space agency Roscosmos, are scheduled to launch Oct. 14 on the Soyuz MS-17 spacecraft from the Baikonur Cosmodrome in Kazakh- stan.
Among some of the hundreds of experiments ongoing during her mission, Rubins will conduct research using the Cold Atom Lab to study the use of laser-cooled atoms for future quantum sensors, and will work on a cardiovascular experiment that builds on an investigation she completed during her previous mission.
NASA selected Rubins as an astronaut in 2009, she was licensed as a Technician class amateur in 2015, and she completed her first space- flight in 2016 as an Expedition 48/49 crew member. She launched July 6, 2016, and spent 115 days in space, during which she conducted two space- walks totaling 12 hours and 46 minutes before her return to Earth Oct. 29, 2016. During her stay on the space station, Rubins helped advance i mportant science and research and became the first person to sequence DNA in space.
Born in Farmington, Connecticut, and raised in Napa, California, Rubins received a Bachelor of Science degree in molecular biology from the University of California, San Diego, in 1999 and a doctorate in cancer biology in 2005 from Stanford University School of Medicine’s Depart- ment of Biochemistry and Department of Microbiology and Immunology in Palo Alto, California. Before joining NASA, Rubins worked as a fellow/ principal investigator at the Whitehead Institute for Biomedical Re- search in Cambridge and headed 14 researchers studying viral diseases that primarily affect Central and West Africa.

A New Way to Obtain GP Data (aka TLEs)
The US government has provided GP or general perturbations orbital data to the rest of the world since the 1970s. These data are produced by fitting observations from the US Space Surveillance Network (SSN) to produce Brouwer mean elements using the SGP4 or Simplified General Perturbations 4 orbit propagator.
Many of you are familiar with this data in the form of TLEs or Two- Line Element Sets. TLEs were designed to provide the minimum data necessary to propagate the orbit of a resident space object (RSO) at a time when both bandwidth for transmission or digital storage were extremely limited. In fact, at the time, transmission might be via fax, hard copy (postal delivery), or even read over the phone and storage was handled using punch cards or magnetic tape.
While this format has served us well for many decades, it has not been without its share of problems. For example, the choice of a two-digit year caused many problems approaching Y2K—problems that were side- stepped by redefining what those two digits represented—but that Y2K problem persists fully 20 years into the 21st century. And now we are approaching another milestone where we will no longer be able to catalog all the objects we track within the 5-digit catalog number limitation of the TLE format.
One of the key drivers forcing us to consider tracking more than 100,000 objects is the activation of the Space Fence on Kwajalein Atoll. The Space Fence reached initial operational capability (IOC) on 2020 Mar 27 and is expected to track far more than the ~26,000 objects currently tracked by the SSN—perhaps by as much as an order of magnitude.
And we are expecting to see public availability of data from the Space Fence starting some time this summer (2020). The 18th Space Control Squadron (18 SPCS) has already transitioned internally to using 9- digit catalog numbers in support of these changes and we expect 18 SPCS to release data from the Space Fence using 9-digit catalog numbers.

Satellite Shorts From All Over
+ FoxTelem / Fox-in-a-Box Tips: 1) Use a short USB extension cord to physically isolate your SDR dongle from the computer/Pi. There will be less mechanical stress, and a better electrical connection, which will give fewer errors. 2) If you use an RTL-SDR dongle (not really supported, but mostly works), don't turn on DUV and High Speed at the same time. You will get an error when the decoder starts. Note especially if you have it set up to start when the satellite comes over the horizon.
