Announcing EO-79 transponder testing for one full orbit - May 4
Wouter Weggelaar PA3WEG from AMSAT-NL reported via the AMSAT-BB that
on Monday May, there is a fairly high chance that the AMSAT-NL
transponder will be tested for one full orbit.
Details will be made available on short notice, but the target time
for an activation starts at approximately 08:30 UTC and may last
until about 10:10 UTC.
The aim of the test is to characterize the power budget on board EO-
79. Usage of the transponder is being encourage. Please also report
the QSOs and signal reports to pa3weg at amsat.org

EO-79 / QB50p1 First Transponder Test Success
AMSAT-NL is delighted to announce that an initial series of tests of
the FUNcube transponder payload aboard the QB50p1 CubeSat have been
successfully completed.
QB50p1 is one of two QB50 precursor spacecraft that were launched
from Yasny in Russia in June 2014.
The primary science payloads are still being extensively tested but
it has now been possible to undertake a short test of the transponder
payload as well. The transponder is intended as a long term secondary
mission following the initial technology demonstration and de-risking
phase.
After spending ten months in space, the transponder was commanded on
for short periods during each of the three morning passes over Europe
on Monday 27th April 2015. A number of FUNcube team members in the
Netherlands and in the UK were standing by to run through a
predefined test plan.
The transponder has a similar performance to that of FUNcube-1 but
the passband is nominally 5 kHz wider by design.
It is not yet known when this transponder may be available for
regular usage but AMSAT-NL is delighted to be able to report that the
hardware is functioning and is very grateful to the QB50 project, the
Von Karman Institute and ISIS B.V. for their ongoing support.
More information about the QB50 project can be found at

"Where Over the World Is Astronaut Scott Kelly?" Geography From
Space Trivia Contest
During his year-long stay on the International Space Station,
astronaut Scott Kelly wants to test your knowledge of the world
through a geography trivia game on Twitter. Traveling more than 220
miles above Earth, and at 17,500 miles per hour, he circumnavigates
the globe more than a dozen times a day. This gives Kelly the
opportunity to see and photograph various geographical locations on
Earth. In fact, part of his job while in space is to capture images
of Earth for scientific observations.
Follow @StationCDRKelly on Twitter and each Wednesday, Kelly will
tweet a picture and ask the public to identify the place depicted in
the photo. The first person to identify the place correctly will win
an autographed copy of the picture. Kelly plans to continue posting
weekly contest photos until he returns from the space station in
March 2016.

Delfi-C3 has been in orbit 7 years
As of April 28, Delfi-C3 has been in orbit 7 years.
Wouter Weggelaarb, PA3WEG, reports, "When we designed Delfi-C3, no-
one would have dreamed it would last this long.
"The satellite still remains healthy and strong. We are delighted to
still get the support of the ham radio community and in all those
years there have been very few days where no telemetry was decoded
and submitted. Thank you very much to those still decoding and
sending in telemetry and also to those still signing up for new
accounts.
"Delfi-C3 has been praised numerous times as the ideal example of a
cooperation of radio amateurs and an university and the team is very
proud of that. Together we have demonstrated the first successful
Distributed Ground Station Network (DGSN) built around radio
amateurs. We as a community can be very proud of this achievement!
Without your continued support, this would not have been possible."
Wouer goes on to report that they may need to re-locate their data
collection server. When this happens he will report appropriate
updates to the AMSAT-BB.

$50SAT/MO-76/Eagle-2 Update
The following status of $50sat/MO-76, one of the first Pocketqubes,
was recently posted by Michael Kirkhart,KD8QBA on the 50dollarsat
Yahoo group. Here is an excerpt:
"17 Months in Space, Still Working, and How Long Will a $10 Camera
Battery last
"Tuesday, April 21, 2015 marked the 17 month anniversary of the
launch of $50SAT/MO-76/Eagle-2, and believe or not, it is still
operating. Unfortunately, the battery capacity has degraded to the
point where the satellite spends a significant amount of time with
the battery voltage below the 3300 mV minimum required for enabling
the transmitter. As a result, those of us who live in the northern
hemisphere no longer hear any transmissions during the evening
passes, and for now, rarely hear any during the daytime passes as
well. The last telemetry packet I captured here in EN82 land was
April 21, and the last one which was error-free on April 10.
Fortunately, I have been able hear it operate over Anton's (ZR6AIC)
WebSDR station in South Africa during the evening passes (which occur
between 4:00 and 6:00 PM Eastern Daylight Time), and occasionally am
able to capture error-free telemetry packets. The last one available
is from April 24 at 21:25 UTC.
"This situation was fully expected; when looking at the battery
voltage chart (which, along with all the other telemetry, is
available from our Dropbox at
https://www.dropbox.com/sh/l3919wtfiywk2gf/AABRl4iM5BFqVAcLQGSmdsVga/
Telemetryanalysis/Current-Telemetry)
the readings took a large drop sometime after February 12. Given
this was a $10 camera battery that had gone through over 6,000
orbits, each with temperature swings of -30 degrees C to +30 degrees
C, it is surprising it has lasted this long! At this point, it is
starting to behave more like a large capacitor than a battery.
"As we get closer to summer here in the northern hemisphere (and
after this winter, it cannot come soon enough), $50SAT/MO-76/Eagle-2
will spend more time in the sun before it makes each pass; this means
it will be warm enough to enable solar power sooner in the pass, and
makes it more likely it we will be able to hear it transmit before it
disappears over the southern horizon. Those of you who live in the
southern hemisphere, however, should still be able to hear it during
both daytime and evening passes. If you could, we would certainly
appreciate any telemetry you could gather and post.
"The orbit continues to decay at an average rate of about 1.5
km/week; apogee is just below 570 km at 569.8 km, and perigee is at
538.2 km. Someday, I will attempt to determine when it might actually
de-orbit. If any of you have access to STK or some other fancy
software which might be able to do a de-orbit prediction, please feel
free to run a simulation and let us all know. Some basic parameters
you might need are as follows:
TLEs as of 2015-04-24, 23:53:15 UTC:
EAGLE 2
1 39436U 13066W 15114.82864817 .00033340 00000-0 23789-2 0 9991
2 39436 97.7463 190.7550 0022811 281.2509 78.6152 15.04244039 77466
Using these, the following can be computed:
Semi-major axis = 5743.7488705249 km
Apogee = 569.7766621696 km
Perigee = 538.1516552847
Average cross-sectional area = 0.014252 m^2
Mass = 210 g
Area/mass ratio = 0.06787 m^2/kg
In the meantime, I will continue to update the Dropbox with any new
telemetry gathered. Please keep it coming, even if it has errors or
is incomplete. At this point, we are happy to simply know that it is
still operating."

AMSAT at the Dayton Hamvention - Fourth call for volunteers
The Dayton Hamvention is less than three weeks away!
Last year, we had 52 people assist with the AMSAT booth at Dayton.
We've had a good response so far to our call for volunteers, but we
could really use another 10-15 people.
The interaction with AMSAT members, satellite operators, designers,
and builders makes the whole experience a lot of fun. Meet or renew
acquaintances, exchange operating tips, and find out what antennas,
software and equipment other AMSAT members use. We currently expect
all of the AMSAT senior officers and 5 of the 7 board members to be
there too.
The 2015 Hamvention is May 15-17. Would you consider helping AMSAT
at Dayton this year?
If you're an experienced operator, great! We can use you and your
experience.
If you've never operated a satellite before, but want to learn more,
that's OK. We can use your help too.
Whether you're available for only a couple of hours or if you can
spend the entire weekend with us, your help would be greatly
appreciated.
Please send an e-mail to Steve, n9ip ＠ amsat.org if you can help.
Thank you!

AMSAT Plans Dayton Rollout for 2015 "Getting Started" Satellite Book
Gould Smith's book, "Getting Started With Amateur Satellites", is
being updated to tell you all about how you can get ready to operate
through the Fox-1 satellites launching later this year. Additional
chapters in the book tell you about tracking software, orbital
mechanics, antennas, radios, Doppler tuning, and operating
techniques. Chapters are also being added to tell you about the new
satellites soon becoming available for amateur radio.
Going beyond brief descriptions in hamfest flyers, this book will
provide a complete reference for new satellite users to assemble a
basic station and to make your first satellite contacts. Also this
book you will teach you how to incrementally upgrade your initial FM
satellite station, time and budget permitting, to include automated
tracking as well as operating through the CW/SSB linear passband
satellites.
A companion Fox-1A reference sheet is also being planned for release
at Dayton. This will be made available for AMSAT's FieldOps team for
distribution at hamfests and satellite operating demonstrations.
Watch for the 2015 "Getting Started With Amateur Satellites" book
and reference sheet at the AMSAT booth at the Dayton Hamvention. The
book will also be available in the AMSAT Store shortly after Dayton:

AMSAT FieldOps Team SO-50 Operating Guide is Available
AMSAT's Director of Field Operations, Patrick Stoddard, WD9EWK says
the FieldOps team is working to make how-to-operate-satellites
information readily available on the web. Based on a hamfest handout
designed and written by Patrick, "Getting Started with the FM
Satellites", is available for download. Patrick shows the basic
equipment and techniques to learn successful operating on the
satellites. This guide also gives specific information on how to
operate via SO-50, the only currently available FM satellite at the
moment.
Patrick's guide is posted at:
