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 often

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 radiation 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’ design, and decided to try stacking them to see if I could achieve more gain Modelling 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 a gamma 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 transmitting in 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 10368-10370 MHz band

The SUWS WebSDR is located at Farnham not far from London, 51 3 N 1 15 W, listen to it at http://websdr suws org uk/

Full details of the antennas are available at http://g8jnj webs com/currentprojects htm

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 birthday

Images received by radio amateurs world-wide may be viewed on-line at: http://www spaceflightsoftware com/ARISS_SSTV/

AMSAT-UK provides a good reference page to prepare amateur radio operators to set up their stations for future SSTV events from the ISS: http://amsat-uk org/2015/02/11/more-iss-slow-scan-tv/

Enthusiastic comments posted on amsat-bb indicated world-wide success:

Fer, IW1DTU wrote, "ISS SSTV, strong signal "

Roland, PY4ZBZ wrote, "Picture received in Brazil 22 feb 2015: http://www qsl net/py4zbz/satelite/Hist33 jpg

Ken, GW1FKY commented, "Received very strong and clear pictures using my Kenwood THD-7 on a pass 1416 hrs plus, at my QTH in Wales UK This was despite very heavy rain and severe flooding in the area

Greg, KO6TH wrote, "I've never received a clearer SSTV picture from anywhere, let alone outer space! Using a Yaesu FT-847 and MMSSTV software running under Wine on my OpenSuSE Linux box "

Steve, AI9IN wrote, "Just got a nice download of picture 12/12 Series 1 from ISS Have a 5/8 wave vertical on the roof going to an old Yaesu 2 m multi-mode used MMSSTV My first SSTV from the ISS!"

CubeSats Offered Deep-Space Ride on ESA Asteroid Probe

Think of it as the ultimate hitchhiking opportunity: ESA is offering CubeSats 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 institutes and 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 October 2020

"AIM has room for a total of six CubeSat units," explains Ian Carnelli, managing the mission for ESA "So potentially that might mean six different one- unit CubeSats could fly, but in practice it might turn out that two three-unit CubeSats will be needed to produce meaningful scientific return

"We're looking for innovative ideas for CubeSat-hosted sensors that will boost 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 industry and 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 Earth in 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 being 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 deep-space 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 challenges

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 address the 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 over the 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 Facility

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 of SLS

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 http://www nasa gov/multimedia/nasatv/index html 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:

http://twitter com/WD9EWK

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:

http://www youtube com/va7ewk

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

73!"

Satellite Shorts From All Over

S-band Moonbounce Update

The frequency and schedule has changed slightly As before, we're going to aim at Tycho from DSS-24 (34m antenna) 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 be easy to see

For the next hour, we'll be transmitting a JPL ranging code with the chip rate at 2115/2048 MHz (a bit more than 1 MHz) See the 810-005 handbook for details http://deepspace jpl nasa gov/dsndocs/810-005/214/214-1 pdf

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 compensating the uplink so that the received signal at JPL will have zero Doppler

This is all "we hope" it's experimental and a sort of procedural shake out as well as giving me a chance to test my ground copy of a Software Defined Radio that is flying on ISS
