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 https://www qb50 eu/

"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!

[ANS thanks Steve N9IP for the above information]

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: http://store amsat org/catalog/
