Eclipses Continue to Affect AO-51 Operation

AMSAT News Service Bulletin 156.01
June 5, 2011
BID: $ANS-156.01

Last week's ANS bulletins reported that the AO-51 Command Team had
successfully restored the satellite to partial operations. AO-51 at
that time required a reload/reboot sequence every time it emerged
from eclipse due to the Integrated Housekeeping (IHU) computer crash-
ing from low battery voltage. 

This week AMSAT VP-Operations, Drew Glasbrenner, KO4MA said, "AO-51's 
computer has been running for over 5 hours now. We have left the sat-
ellite in repeater mode 145.88/435.15 for the time being, at over 2 
watts. We are very surprised by this development to say the least. 
Without Whole Orbit Data we are flying a bit blind, so would really 
like to know what the satellite is doing in eclipse. Please send your 
reports to me or to the amsat-bb. Southern hemisphere observations 
are most very welcome." 

+ Robert, NH7WN reported from Honolulu: "AO51 was alive and well as 
  she came out of eclipse on June 2. I was able to hear myself per-
  fectly on the downlink (145.880 up and 435.150 down)." 

+ Brett reported: "Heard on AO-51 today pass over Australia/New Zealand
  145.880/435.150 Strong signals. Copied VK1AMG, ZL2BX, VK4VDX."

+ Alan, ZL2BX reported: "AO-51 solid signals in ZL. AOS (0459 UT) about 
  five minutes after it came out of eclipse. Later on June 3, I can 
  finally confirm that AO-51 is loud and clear over ZL in full eclipse. 
  with solid signals from the transponder."

+ Dave, KB5WIA reported from California, "AO-51 was in great shape as 
  it passed south above the Pacific Ocean on June 3. I had a nice S9+ 
  full quieting downlink for the entire pass."

The Command Team has analyzed AO-51 live telemetry when the satellite 
is in range of a ground station because Whole Orbit Data is lost when
the IHU Computer crashes. Drew, KO4MA summarized, "Cell 3 is reporting 
0.0 volts, so it's clear it has shorted completely."

Donations for Fox and ARISSat-1 are being collected. If you haven't 
yet donated, please drop by http://www.amsat.org, or call Martha at 
the AMSAT Office at 1-888-322-6728 today and help us get Fox in space.

AMSAT-DL Break FUNcube Dongle Distance Record

AMSAT News Service Bulletin 156.05
June 5, 2011
BID: $ANS-156.05

A story first reported on the Southgate ARC news web site reported
members of AMSAT-DL have received the Stereo B spacecraft at a dis-
tance of 219 million kilometers using an AMSAT-UK FUNcube Dongle 
Software Defined Radio as the I.F. in combination with a downcon-

Stereo B transmits in the X band around 8 GHz so could not be receiv-
ed by the FUNcube Dongle directly since that covers 64-1700 MHz. A 
downconverter was installed at the dish feed and the 1280 MHz output 
was fed into the FUNcube Dongle SDR.

The frequency of Stereo B varies due to Doppler shift (of the rotating 
Earth) and was calculated by the tracking software.

Watch Mario Lorenz DL5MLO explain how the record was broken Receiving 
Stereo B with a FUNcube dongle and the Bochum 20m dish:

+ Check your ISS Keps! According to Roscosmos, the ISS boosted its orbit 
  by 3.74 km Friday. This will result in a "slippage" of predicted times 
  of approximately 70 seconds per day until the Keps catch up. The AMSAT 
  NASA.ALL Keps will probably not reflect this until next week, so be 
  certain to update from Celstrak or Space Track.

2011 AMSAT Field Day Competition

AMSAT News Service Bulletin 156.07
June 5, 2011
BID: $ANS-156.07

AMSAT Director of Awards, Bruce Paige, KK5DO says, "It's that time 
of year again: Summer and Field Day!"  

Each year the American Radio Relay League (ARRL) sponsors Field 
Day as an emergency preparedness exercise. The event takes place 
during a 24-hour period on the fourth weekend of June.  For 2011 
the event takes place during a 27-hour period from 1800 UTC on 
Saturday June 25, 2011 through 2100 UTC on Sunday June 26, 2011. 
Those who set up prior to 1800 UTC on June 25 can operate only 
24 hours. 

The Radio Amateur Satellite Corporation (AMSAT) promotes its own 
version of Field Day for operation via the amateur satellites, 
held concurrently with the ARRL event.

Bruce advises, "If you are considering ONLY the FM voice satellites 
like AMRAD-OSCAR-27, SaudiSat-Oscar-50, or AMSAT-OSCAR-51 for your 
AMSAT Field Day focus. Don't, unless you are simply hoping to make 
one contact for the ARRL rules bonus points."

The congestion on FM LEO satellites was so intense in prior years 
that we must continue to limit their use to one-QSO-per-FM-satel-
lite. This includes the International Space Station. You will be 
allowed one QSO if the ISS is operating Voice. You will also be 
allowed one digital QSO with the ISS or any other digital, non-
store-and-forward, packet satellite (if operational).

US Army Supports Student Launch Program

White Sands Missile Range NM (SPX) Jun 03, 2011. A scientific rocket 
screamed skyward at Spaceport America May 20, 2011, as students from 
all over New Mexico, as well as Texas and Arizona came to see their 
scientific payloads fly into space during a scientific and educational 
mission supported by White Sands Missile Range.

The rocket carried 27 experiments from elementary, middle schools, 
high schools and universities into space before returning to earth, 
and landing at White Sands Missile Range, or WSMR. Under the New 
Mexico Space Grant Student Launch Program, students were able to 
assemble their own scientific payloads to be launched over 65 miles 
above the earth.

The student payloads, divided into seven different canisters within 
the rocket were a varied as the students who built them. Crammed into 
the canisters were cameras, radiation monitoring sensors, and other 
measurement devices, along with some more advanced systems.

"We had things from roasting green chilies to marshmallows to using 
a piezo electric board, tesla coils, and a lot of temperature monitors 
and Geiger counters, a bunch of variety, and a lot of magnetic experi-
ments also," said Bruce Lewis with the space grant office and spaceport 

The rocket launch represented more than just an educational opportun-
ity for the students, but a cooperative effort between different 
organizations and companies. Even though the rockets flight began at 
Spaceport America, a state-run spaceport, it ended its flight on White
 Sands Missile Range and used range airspace.

"This is White Sands airspace that we're flying in, so White Sand 
controls that airspace for us. We have a great relationship with White 
Sands and we had a lot of support from (WSMRs) team," said Pat Hynes, 
director of the Space Grant Consortium.

The recovery of the rocket, and it's return to the students was con-
ducted by White Sands Missile Range's Army Air. While the rocket was 
awaiting recovery White Sands Missile Range Chief of Staff Dan Hicks 
spoke with the students about the future of high technology careers 
and the kind of opportunities in those fields offered by WSMR and the 

"The majority of the workforce consists of engineers and mathematicians 
and other scientific fields. We've got about 4,000 people on the test 
center and garrison side that have that type of background. So in order 
to be specific to what it takes to get a job out at White Sands one of 
the key things would be to continue your education into college and get 
a degree," Hicks said.

Hick Also answered questions from the students about spaceflight, how 
the range operates and the kind of radar systems used to track rockets 
like the one used in the experiment.

Data collected by these various devices had a variety of applications, 
with some being educational in nature, giving the students a glimpse 
of what it means to send something into space, and other experiments 
having more direct applications to the future of space flight.

"Some of it is great data; some of it is fun data. So you're got both 
the fun stuff and some things that are collecting real empirical data 
that NASA may be able to use in the future," Lewis said.

One experiment bridged the gap between the two. An experiment conducted 
by Aztec High School harvested the physical motion of the rocket in 
flight and converted it into electricity which was then used to power a 
small electric oven and roast a green chili. While roasting green chilies 
isn't critical to the future of space flight, the electricity could have 
other purposes.

"What we wanted to see is if you could power something in the rocket 
just using piezo electrics, just using the own forces of the rocket to 
generate it's own electricity while flying up into space," said Braden 
Goimarac, from Aztec High School's "Black Ops" science team.
