ISS SSTV in a Brazilian School
One of the members of the newly formed Brazil's AMSAT-BR group, Paulo,
PV8DX, demonstrated amateur radio on Monday, February 23, 2015 at the
Gonçalves Dias school when he demonstrated receiving an ISS SSTV picture on
145.800 MHz FM.
The ISS pass he received did not produce a strong signal and only part of
the picture was captured but as can be seen from the video the students were
enthusiastic and excited to be receiving a signal from space.
Paulo expressed the hope that the ISS will send images on school days more

Space Station SSTV and Packet Radio via SUWS WebSDR
Martin Ehrenfried G8JNJ reports excellent SSTV and Packet Radio signals from
the International Space Station (ISS) using the online SUWS WebSDR.
The omni-direction helix antennas at the WebSDR were designed with high
elevation satellites in mind. Conventional antennas concentrate the
pattern towards the horizon resulting in weaker signals when a satellite is
above 15 degrees elevation. Comparisons with other WebSDRs show the SUWS
antennas provide a 6 to 10dB better signal to noise ratio on similar passes.
Martin says: “I had been experimenting with single turn ‘twisted halo’
and decided to try stacking them to see if I could achieve more gain.
suggested that a stretched 3 turn helix with a helix circumference of approx
1/2 wave length and an overall length of 1/2 wave at 70cm, and fed with
match at the centre would offer reasonable gain, an omni-directional pattern
and mixed polarisation.”
You can use the free online SUWS Web Software Defined Radio from your PC or
Laptop to receive the ISS and the many amateur radio satellites
the 144-146 MHz or 435-438 MHz bands. It also provides reception of High
Altitude Balloons in the 434 MHz band and coverage of the microwave
The SUWS WebSDR is located at Farnham not far from London, 51.3 N 1.15 W,
listen to it at

SSTV From the ISS Completed This Week
Following a short delay in amateur radio operations aboard the ISS due to
schedule changes in EVA activity, the Slow Scan Television transmissions
were sent on Sunday, Monday, and Tuesday, February 22-24. The transmissions
originated from the Russian segment of the ISS using a modified Kenwood
radio and an external antenna on the ISS. The callsign of RS0ISS was used.
SSTV signals received on 145.800 MHz using the PD180 high resolution mode
featured 12 different photos of the first cosmonaut Yuri Gagarin. Also
included was a photo of a commemorative diploma created by the National
Polish Amateur Radio Society celebrating the 80th anniversary of Gagarin's
Images received by radio amateurs world-wide may be viewed on-line at:
AMSAT-UK provides a good reference page to prepare amateur radio operators
to set up their stations for future SSTV events from the ISS:

CubeSats Offered Deep-Space Ride on ESA Asteroid Probe
Think of it as the ultimate hitchhiking opportunity: ESA is offering
a ride to a pair of asteroids in deep space. CubeSats are among the smallest
types of satellites: formed in standard cubic units of 10 cm per side, they
provide affordable access to space for small companies, research
universities. One-, two- or three-unit CubeSats are already being flown.
Teams of researchers and companies from any ESA Member State are free to
compete. The selected CubeSats will become Europe's first to travel beyond
Earth orbit once the Asteroid Impact Mission (AIM) is launched in
"AIM has room for a total of six CubeSat units," explains Ian Carnelli,
managing the mission for ESA. "So potentially that might mean six
unit CubeSats could fly, but in practice it might turn out that two
CubeSats will be needed to produce meaningful scientific return.
"We're looking for innovative ideas for CubeSat-hosted sensors that will
and complement AIM's own scientific return.
"We also intend to use these CubeSats, together with AIM itself and its
asteroid lander, to test out intersatellite communications networking.
"ESA's SysNova initiative will be applied to survey a comparatively large
number of alternative solutions, this competition framework giving
universities the opportunity to work together on developing their scientific
investigations in a field that is the technological cutting edge."
Beginning its preliminary Phase-A/B design work next month, ESA's AIM
spacecraft will be humanity's first mission to a binary system - the paired
Didymos asteroids, which come a comparatively close 11 million km to
2022. The 800 m-diameter main body is orbited by a 170 m moon.
AIM will perform high-resolution visual, thermal and radar mapping of the
moon. It will also put down a lander - ESA's first touchdown on a small body
since Rosetta's Philae landed on a comet last November.
AIM also represents ESA's contribution to a larger international effort, the
Asteroid Impact and Deflection Assessment (AIDA) mission.
The NASA-led Double Asteroid Redirection Test (DART) probe will impact the
smaller body, while AIM will perform detailed before-and-after mapping,
including pinpointing any shift in the asteroid's orbit.
"While it will return invaluable science," adds Ian, "AIM is conceived as a
technology demonstration mission, testing out various technologies and
techniques needed for deep space expeditions in future.
"These include two-way high-bandwidth optical communications - with data
returned via laser beam to ESA's station in Tenerife - as well as
intersatellite links in deep space and low-gravity lander operations.
"Once demonstrated, these capabilities will be available to future
endeavours, such as Lagrange-point observatories returning large amounts of
data and sample return missions to Phobos - and ultimately Mars - as well as
crewed missions far beyond Earth orbit."
The chance to put forward CubeSats is being organised as a SysNova
competition, an initiative by ESA's General Studies Programme - which is
running the AIM project - to compare innovative solutions to space mission
Interested teams can get more information from the published announcement of
opportunity. As a next step, qualified teams can submit initial 'challenge
responses' describing their proposed mission concepts and how they
defined technical challenges associated with operating such small spacecraft
close to an asteroid.
The winning submissions will then be funded by ESA for further study
next seven months, following up with a final review at ESA's ESTEC technical
centre in Noordwijk, the Netherlands. The victors will then work with ESA to
elaborate their designs, including sessions at ESTEC's Concurrent Design

Live Broadcast of Space Launch System Booster Test Firing
Did you know that NASA is building the largest solid propellant rocket
booster in the world? NASA will test this booster, designated Qualification
Motor-1, or QM-1, on March 11, 2015, at the Orbital ATK test facility in
Promontory, Utah. The test is scheduled for 11:30 a.m. EDT.
QM-1 is a five-segment solid propellant booster that will help power the
Space Launch System. The two-minute, full-duration static test is a huge
milestone for the SLS Program and will qualify the booster design for
high-temperature conditions. This type of test typically comes only after
multiple years of development and signifies major progress being made on the
rocket. Once this test and a second, low-temperature test planned for early
2016 are complete, the hardware is qualified and ready for the first flight
NASA's Space Launch System will be used to help send humans to deep space
destinations like an asteroid and Mars. SLS is an advanced, heavy-lift
launch vehicle that will provide an entirely new capability for science and
human exploration beyond Earth's orbit. The SLS will give the nation a means
to reach beyond our current limits and open new doors of discovery from the
unique vantage point of space.
The test will be streamed at
and broadcast on NASA TV.
Please make plans to watch with your students and colleagues.

AMSAT at the Yuma Hamfest Wrapup Report
AMSAT Vice President for Field Operations, Patrick Stoddard, WD9EWK,
writes a little about the two-day Yuma Hamfest that he attended
with an AMSAT booth. "This hamfest has become (I think) the largest
in Arizona, and I heard that over 1000 hams attended. It draws hams
from all over Arizona, California, Nevada, and the "snowbirds" from
other parts of the US and Canada. And a few hams came up from
northern Mexico to join in the fun.
There was steady traffic past the AMSAT booth on both days. I had
Rick, K7TEJ helping me for much of the weekend, and his help was
appreciated very much. He left his homebrew dual-band Yagi (2
elements on 2m, 5 on 70cm) on a telescope mount and tripod at
the AMSAT booth during the two days, along with my Elk 2m/70cm
log periodic. Between the two of us, we had demonstrations on two
AO-73 passes, two SO-50 passes, and one pass each on 3 other
satellites (AO-7, FO-29, NO-44), with a total of 34 QSOs. Lots of
flyers and the Getting Started with Amateur Satellites books were
flying off the table, and we had good crowds for the demonstrations
outside the main building on the Yuma County Fairgrounds. I posted
pictures from the hamfest over the two days on my @WD9EWK
Twitter feed. You are welcome to look through my feed and see those
photos and other comments at:
if you are not a Twitter user.
The SO-50 passes, as expected, were the busiest of the passes worked
from Yuma. Much of the time, those passes were great illustrations of
what can be heard on an FM satellite. Even some of the not-so-good
operating examples made for excellent teaching moments.
I don't have any videos of the demonstrations this year, but have some
videos of the aircraft flying into or out of Marine Corps Air Station Yuma,
the airfield across the street from the hamfest site (the runways at that
airfield are shared with Yuma International Airport, with both civilian and
military aircraft coming and going throughout the day). Those videos,
and others I have uploaded over the years, can be viewed at:
Thanks to everyone who worked WD9EWK during the hamfest. And a
special thank-you for those who were standing by to work me, as I tried
to complete QSOs with other stations that may have been closer to their
LOS times than you. I have uploaded those QSOs to Logbook of the
World. Please e-mail me directly (with QSO details) if you'd like to
receive a WD9EWK QSL card to confirm those QSOs. You don't have
to send me a card or SASE first. The hamfest was in grid DM22.

G. Salvemini – G. La Pira
“Salvemini – La Pira” is a secondary middle schoo located in Montemurlo,
province of Prato, in the Tuscany region. The school has 21 classes with
ages 11 to 14 with a total of 520 pupils. The name of the school derives
the fusion of the two schools of the commune. This is the only secondary
school in the area.
The "Dante Alighieri" School is situated outside the town center of Casale
Monferrato, near the ancient Cittadella, province of Alessandria, in the
Piedmont region. It is a modern construction, developed on two main
one for the school's didactical and administrative activities, one for the
sport activities (gym and pool). It is surrounded by a wide playground,
little plantation of poplars, planted by the pupils of the school. There
classrooms (4 on the main floor and 8 on the first floor) and several labs,
including a Science Lab, Informatics Lab, Techno Lab, Art Lab, Maths
Lab, and a
Languages Lab, and a colorful and expansive library. There also a lot of
afternoon activities, such as Latin courses, languages courses and sport
tournaments (soccer, basket, volleyball). The Dante Secondary I grade School
has a current roll of 230 students and a teaching staff of 29. In the
years the school has been enhanced by the richness of its diverse student

We'll radiate at 2115 MHz (not 2401 MHz).. from 0630UTC to 0900 UTC
For the first hour (until 0730UTC) we'll just have a CW carrier, should

You can probably see not only the carrier but the +/-1 MHz ranging tones
(and probably at +/-2 MHz, too), and also the PN sequence if you've got
enough SNR (or post process.. the code period is about 1 second.. it's
about a million chips long)
Then, at 0830UTC we'll stop using the PN ranging, and go to Doppler
