Jean-Marie KI4YAU asks Amateur Radio operators to listen out for AubieSat-1, on 437.475 MHz CW, after its launch on October 25 at 0952 UTC.

We fervently request your assistance in receiving transmissions from an upcoming satellite, AubieSat-1, immediately after its launch from Vandenberg AFB, California, USA, 25 October 2011 at 9:52 UTC.

AubieSat-1 (AS-1) is an undergraduate – built CubeSat satellite developed by Auburn University.

AS-1 is designed to transmit with a power of about 800 milliwatts on a frequency of 437.475 MHz, plus or minus Doppler correction [+/- 9 kHz]. The beacon signal, along with telemetry, will be sent using A1A continuous wave Morse code at 20 words per minute. Additional telemetry from the onboard science experiment will use CW transmissions up to 60 WPM.

Based on the pre-launch orbital data provided by NASA, AS-1 will activate after deployment at 12:21 UTC, 25 October 2011.
At that time, the sub-satellite point will be at 34.52 S latitude and 1.52 W longitude over the South Atlantic Ocean.

Our predictions are that the first flights over the contiguous United States will begin as shown in the following table:

This information will be updated should there be launch scrubs or performance changes in the launch, and additional information will be available upon request for specific locations.

Reception reports with data contents are welcomed to the following email addresses:
wersijp at auburn dot edu and tam0013 at auburn dot edu

An internet Echolink conference group is also planned to begin one-half hour prior to launch and continue until about 30 minutes after confirmation of the first receipt of signals from the satellite.

Information on the conference groups title will be distributed nearer to the launch for interested stations.

Please email wersijp at auburn dot edu if you require additional information and can assist in the reception and tracking of AS-1.

Thank you.

The Amateur Radio CubeSat FITSAT-1 plans to transmit 115.2 kbps digital data in the Amateur Satellite Service 5.8 GHz band and will also carry an Optical Communications experiment.

FITSAT-1 (aka NIWAKA) is a 1U CubeSat (10*10*10cm) that should be be deployed from the International Space Station by robot arm in late 2012. It will generate about 2W RF output using a 16W DC input.

The main mission will be to demonstrate high speed data transfer from a satellite, it can transmit a VGA-size (640×480 pixel) JPEG photograph in only 5 to 6 seconds.

The second mission is to determine if a satellite can be made to appear as an “artificial star” using high-output LEDs in flash mode. The light from this flash will be received by the ground station, which has a telescope with photo-multiplier linked to a 5.8GHz parabola antenna. This is a basic experiment to investigate the possibility of optical communication with satellites.

A UHF AX25 1k2baud transceiver will also be carried for telemetry and telecommand purposes and a UHF CW beacon will also be provided. It will be deployed along with the satellites RAIKO and WEWISH into a 350x350km 51.6deg inclination orbit.

The following downlink frequencies have been coordinated by the IARU Satellite Frequency Coordination Panel: CW 437.250 MHz, FM 437.445 MHz, High speed data 5840.00 MHz.

(not up and running currently)

To switch the transmitter on, you need to send a CTCSS tone of 74.4
Hz. The order of operation is thus: (allow for Doppler as necessary):
1) Transmit on 145.850 MHz with a tone of 74.4 Hz to arm the 10 minute
timer on board the spacecraft.
2) Now transmit on 145.850 MHz (FM Voice) using 67.0 Hz to PT the re-
peater on and off within the 10 Minute window.
3) Sending the 74.4 tone again within the 10 minute window will reset
the 10 minute timer.

ARISSatTLM software author, Douglas Quagliana, KA2UPW/5 says a new
ARISSat-1/KEDR telemetry web page is now available at:

http://www.arissattlm.org/live

The new telemetry page is intended to be viewed on a computer (or
large screen computing device). It shows all of the telemetry values
that you would see if you were running ARISSatTLM at your station.

The data on this page is updated once a minute when ground stations
are within range of ARISSat-1/KEDR and forwarding live telemetry re-
ceived via ARISSatTLM. Since it depends on stations forwarding tele-
metry over the Internet, there will occasionally be periods without
any updates.

The original ARISSat-1/KEDR telemetry page is still up and running.
(see: http://www.arissattlm.org/mobile). The difference is that the
“mobile” page is designed to be viewed on a cellphone or other small
screen computing device.

Both pages are updated at the same time from the same telemetry. The
“live” page just shows more telemetry.

Please keep forwarding in your telemetry over the Internet. Also, if
you received any telemetry from ARISSat-1, even if you are forwarding,
please email the .CSV file(s) to: [telemetry at arissattlm dot org].
The .CSV files are in the “Telemetry” folder which is in the ARISSatTLM
folder on your desktop.

BID: $ANS-247.03

Now up to 665 ARISS contacts from the ISS to school contacts the
International Space Station school contact with Merritt Island High
School, Merritt Island, Florida on August 30 added another success.

The contact was a direct link between NA1SS and WB2IHB. “NA1SS,
NA1SS, NA1SS, this is WB2IHB in Merritt Island, Florida.” Then, a
crackle. “I read you loud and clear,” said Japanese Astronaut Sat-
oshi Furukawa. Fourteen-year-old Brandon Arena was first in line
to ask Furukawa a question. So began the contact. The Florida
Today newspaper reported on the event and the enthusiastic stu-
dent response at:

http://www.floridatoday.com/apps/pbcs.dll/article?AID=2011108310317

The link above includes a video, and photos along with a report
of the event that was well received by the students and their par-
ents and teachers.

Merritt Island High is a public high school with a student population
of 1500. Sixty of these students are members of the Da Vinci Academy
of Aerospace Technology, where these engineering-minded students take
part in the “Project Lead the Way” engineering curriculum. Fifteen
students were selected from the Academy to engage the astronaut in a
question and answer session as the ISS passed over the school.

ARISS is an international educational outreach program partnering the
participating space agencies, NASA, Russian Space Agency, ESA, CNES,
JAXA, and CSA, with the AMSAT and IARU organizations from participa-
ting countries.

ARISS offers an opportunity for students to experience the excite-
ment of Amateur Radio by talking directly with crewmembers on-board
the International Space Station. Teachers, parents and communities
see, first hand, how Amateur Radio and crewmembers on ISS can ener-
gize youngsters’ interest in science, technology, and learning.

Further information on the ARISS program is available on the website
http://www.ariss.org/ (graciously hosted by the Radio Amateurs of
Canada).

BID: $ANS-247.05

AMSAT-UK’s FUNcube is an educational single cubesat project with the
goal of enthusing and educating young people about radio, space, phy-
sics and electronics. FUNcube will carry a UHF to VHF linear transpon-
der that will have up to 1 watt and which can be used by Radio Ama-
teurs worldwide for SSB and CW communications. Measuring just
10 x 10 x 10 cm, and with a mass of less than 1kg, it will be the
smallest ever satellite to carry a linear transponder

It will support the educational Science, Technology, Engineering and
Math (STEM) initiatives and provide an additional resource for the
GB4FUN Mobile Communications Centre.

The target audience consists of primary and secondary school pupils
and FUNcube will feature a 145 MHz telemetry beacon that will provide
a strong signal for the pupils to receive.

A simple SDR receiver board (FUNcube Dongle) has been developed to
support this mission by providing a simple radio interface to the
classroom. The FUNcube Dongle connects to the USB port of a laptop
to display telemetry and messages in an interesting way for students.

But, even before FUNcube has been launched amateur satellite operators
have discovered that the 64 MHz to 1,700 MHz coverage of this Software
Defined Radio receiver can be used for most amateur, along with some
weather and commercial satellite reception.

This week, Simon Brown, GD4ELI/HB9DRV, announced he has enhanced his
popular SDR-RADIO software to provide support for the AMSAT-UK FUNcube
dongle software defined radio. The SDR-RADIO.com software has been up-
graded to provide full support for the FUNcube dongle including satel-
lite tracking, Doppler compensation and data for external rotator
software via DDE. This free software can be downloaded from

BID: $ANS-247.08

The International Amateur Radio Union (IARU) Region 1 meeting in Sun
City, South Africa this week noted that several Italian repeaters are
currently causing on-going interference to satellite uplinks and down-
links in the Amateur Satellite Service segment from 145.8-146.0 MHz.

While the IARU R1 decision stressed the importance of the satellite
service they also noted that coordination is needed to continue to
introduce new modes. The IARU R1 C5 committee report recommended
that the D-STAR repeaters/nodes that continue operation in contra-
diction to the IARU-R1 band plans be disconnected from the inter-
national D_STAR network.

The IARU-R1 Sun City conference SC11_C5_16 committee meeting notes
say that initial methods listed below were passed unanimously:

1. Write the repeater operator to remove [their operating frequency]
out of the satellite segment.
2. Inform the trust server operator of the IARU bandplan breach made
by the use of the repeater.
3. Inform the government about the repeater and request them to remove
the repeater.

ESA Successfully Repressurizes Satellite With Solid State Stored Gas

AMSAT News Service Bulletin 247.09
From AMSAT HQ SILVER SPRING, MD.
September 4, 2011
To All RADIO AMATEURS
BID: $ANS-247.09

The European Space Agency reported that its August 16 test to re-
pressurize gas tanks aboard their Proba-2 spacecraft were successful.
Proba-2 was launched on 2 November 2009. Less than a cubic metre in
volume, it carries a total of 17 new technologies and four science
payloads focused on the Sun and space weather.

According to the ESA, Proba-2 uses a ‘resistojet’ engine to maintain
the microsatellite’s orbit at 600 km altitude. This experimental en-
gine runs on xenon gas heated before ejection to provide added thrust.

Laurens van Vliet of Dutch research organisation TNO, which developed
the technology explained, “What makes this repressurisation unique is
that the added gas was not stored in a pressurised state but produced
from a solid material at room temperature, the first of four ‘cool-gas
generators’ on Proba-2. Nitrogen, like xenon, is an inert, non-react-
ive gas, so the resistojet can work just as well with a xenon-nitrogen
mixture.”

The bottle-shaped cool-gas generators are filled with a rigid solid
material that, once triggered, produces more than 250 times its own
volume in pure nitrogen gas. The other three generators will be used
later in Proba-2′s orbital lifetime.

EduSat Mission to Test PocketQub Satellite Orbital Deployment System

AMSAT News Service Bulletin 247.10

September 4, 2011
To All RADIO AMATEURS
BID: $ANS-247.10

The PocketQub is a new satellite standard that was proposed in 2009
by Professor Robert Twiggs, W7RMT at Kentucky’s Morehead State Uni-
versity (MSU) for a satellite even smaller than the CubeSat. Pocket-
Qubs are 5 cm cubes and can literally fit in a pocket. The PocketQub
leverages the CubeSat standard and the revolution in the miniaturiza-
tion of electronics. PocketQubs will ultimately have a wide range of
applications including: Network Nodes, Sensor Systems, Satellite Con-
stellations, Inexpensive, Redundant, and Spatially Organized Earth
Remote Sensing Platforms.

Morehead State University’s Space Science Center (SSC) and Kentucky
Space collaborated with the University of Rome Sapienza Aerospace
Engineering School on a series of student-driven educational satel-
lite projects. The goal was for students to develop, build and fly
a series of four satellites (EduSat, UNISAT-5, UNISAT-6, and UNI-
SAT-7). These satellites were built in Rome and in Morehead and
controlled from MSU by students using the big dish antenna and by
Italian students using satellite ground assets in Europe.

EduSat was launched in August, 2011 by a Russian Dnepr rocket from
a silo. During its first 30-days on orbit, EduSat will test an orb-
ital deployer designed to release the PocketQub, also called a femto-
class satellite. While the femtosats will not be released on the
first mission, the deployment system that will ultimately deploy
them will be tested. A follow-on mission in 2012 (UNISAT-5) will
deploy four femto-class satellites when they are ejected from the
UNISAT-5 “mothership” at apogee.

ARISSat-1/KEDR Project Manager Gould Smith, WA4SXM reported on this week’s status of the satellite.

Gould noted that while the battery performed as expected during the first week of operation. Lower voltages during eclipse began to show up in the telemetry on 10 Aug 2011.

The voltages during eclipse have continued to decline causing the satellite to reset and occasionally go into Emergency power mode.

Gould explained the changes noted on the 145.950 MHz FM downlink that were heard this week:

• A Male voice for the spoken telemetry means that the female voice files on the SD card could not be read.

• If no greetings are transmitted this means that these message stored on the SD card could not be read.

• A short Mission-Elapsed-Time (minutes to hours) has been noted while the satellite was still in a long period of sunlight indicating that satellite must have reset during sunlight.

Reports received on later orbits indicated that the female voiced
telemetry and the greetings messages had returned to normal operation once the solar panels had recharged the battery.

After each reset the satellite MET (Mission Elapsed Timer) goes to 000, waits during the 15 minute TX delay, the power management software checks the current voltage and power values and determines what power mode to operate the satellite. The power mode is re-determined at fixed intervals, especially during illuminated periods to provide the most transmitted signals while protecting the battery.

High power mode provides continuous transmission when sunlight is charging the battery. If the satellite has entered low power mode it will transmit for 40 seconds and remain idle for 2 minutes when in eclipse, or when the battery voltage is low.

The ARISSat-1 team is closely monitoring the situation and is pleased with how well the power management software is controlling the battery usage to prolong the lifetime of the battery and the satellite as much as possible.

Please send your BPSK telemetry into the server arissattlm.org.

AO-51 Control Station, Mark Hammond, N8MH wrote a status update on
this satellite. Mark noted that since the failure of the first cell
on the six-cell battery the ground controllers have been limited to
simple commands for basic configurations.

Mark said that ground control stations have evolved basic control
and management techniques of AO-51 which allow them to set power
levels manually, change uplinks/downlinks. Additional features such
as telemetry collection/storage, and the BBS are not functional
at this time. If the satellite resets during eclipse these basic
functions must be restored manually by a ground station.

Ground stations have discovered there is a second cell in the bat-
tery showing problems. Mark noted, “We think it will be the next cell
to go with the probable result that our limited manual mode of oper-
ation probably will no longer be an option, and the mission might be
considered over.”

AO-51 is currently transmitting on:

Downlink: 435.150 MHz FM (LHCP) and using a
Uplink: 145.880 MHz FM

The power level is just under 1 watt (about 980 mW). Controllers
expect to keep this configuration until further notice.

The 400 meter diameter near-Earth asteroid 2005 YU55 will be making
a 0.85 lunar distance flyby of Earth on November 8. Michael Busch at
the UCLA Department of Earth and Space Sciences notes this may an
opportunity for amateur satellite operators to observe the fly-by.

UCLA will be conducting an extensive campaign of radar observations
with the Arecibo Observatory, the Deep Space Network Goldstone facil-
ity, and the Green Bank Telescope and the Very Long Baseline Array.

Because YU55 will be so close to Earth, its radar echo will be
detectable with even small antennas (~1 m^2). YU55′s echo will be
a slowly drifting signal with a bandwidth of ~1 Hz within a few kHz
of 2380 MHz or 8560 MHz.

This will present amateur radio operators an opportunity to receive
the radar reflections off of the asteroid because of the big dish,
big signals originating from Arecibo and Goldstone.

On November 8, 2011, 19:15 – 19:30 UTC, Arecibo will be transmitting
a continuous wave tuned to put the asteroid’s echo at a constant
2380.000000 MHz at the Green Bank Telescope. Observers elsewhere on
Earth will see the echo within 2 kHz of 2380 MHz, Doppler-shifted by
the Earth’s rotation. It will be slowly drifting in frequency and
have a bandwidth of ~0.6 Hz.

On November 9, 2011, 01:30 – 02:00 UTC, the Goldstone Deep Space Net-
work facility will be be transmitting a continuous wave tuned to put
the asteroid’s echo a constant 8560.000000 MHz at a second antenna at
the Goldstone site. Other observers may see the echo shifted by as
much as 6 kHz, and it will have a bandwidth of ~2 Hz.

Initial information can be found on-line at:

The Times newspaper reported on an experiment developed by students
in Canterbury that will soon fly in space. They have also teamed up
with students in Uganda.

Students at the Simon Langton Grammar school, led by Head of Physics,
Dr. Becky Parker are developing a Cosmic Radiation experiment (LUCID)
that will be part of the TechDemoSat-1 satellite. It is based around
a Cosmic Ray detector chip from CERN and the school raised £60,000 to
fund the experiment.

The school say that Dr Obote College in Uganda will soon be working
with one of the LUCID cosmic ray detectors and Ugandan students will
play an equal part with Langton students in collecting and analysing
data on cosmic ray activity as part of an international experiment.

As part of the project Dr. Becky Parker is looking for money to install
LUCID equipment in schools across the Britsh Isles and Europe providing
ground-based data in a way that will involve hundreds of thousands of
students.

TechDemoSat-1 (TDS-1) is developed by Surrey Satellite Technology Ltd
(SSTL). The TechDemoSat will function as an ‘in-orbit test facility’
for the UK Space Agency once launched, qualifying onboard payloads as
well as UK satellite software.

At around one meter cubed and a mass of 150kg, TechDemoSat (TDS-1)
will carry no less than eight payloads. Additional features proposed
for this mission include:

+ An enhanced on board computer giving greater ability to conduct
software experiments remotely.

+ A new battery charge regulator and newly qualified cell types on
two of the solar panels.

+ A propulsion system will see a smaller tank size trialled with a new
high performance resistojet thruster.

+ New sun sensors in the Altitude and Orbital Control System.

+ Standard CANbus interface.

donors to AMSAT Project Funds, will be eligible to receive addi-
tional benefits. Application forms are available from the AMSAT
Office. And with that please keep in mind the two ham radio bro-
thers called William and Wayne. Will was a CW operator and Wayne
was a phone operator. Hams noticed they always went around together.
If William went to the CW band, Wayne would be in the shack tuning
the phone band. One ham noticed they were so inseparable. It was
easy to explain, because where there’s a Will there’s a Wayne!

This is speculation but it looks to me like we
have had a bit of good luck regarding the battery.

Looking at the battery voltage from deployment on…

Up until Aug 11, the battery seems to be deteriorating “normally” with a slight downtrend in the max voltage as expected. But on Aug 11, the battery voltage suddenly rises up to 36 V max and the satellite has started resetting in eclipse.

I think the explanation is that the battery experienced a significant event on Aug 11 where it lost the electrolyte in one or more cells. If this is true, the bad news is that it will no longer hold a charge and will not operate in eclipse any more.
But the good news is that without electrolyte, it would also stop dendrite growth that causes the eventual battery short circuit.
In our ground testing, our test battery failed in the usual way with the battery load increasing until the solar panels could not drive the power bus high enough to run the satellite. But interestingly, several cells also cracked and dumped their electrolyte during this testing.
If a cell on the flight battery cracked and dumped its electrolyte BEFORE the shorts were formed, it should stay that way and the satellite may very well continue to operate in the sun until it starts to re-enter. We just need some luck to avoid a bad solar angle that would cause a reset in sunlight

That’s a great idea; I wish I thought of it first, but it was Lou
McFadden W5DID who published a paper at the AMSAT Symposium a few years
ago on a new modular power system.

His idea was to turn each cell into an intelligent energy storage module
and to connect those modules in parallel to a power bus. There’d be a
DC-DC converter between the cell and the bus so they could operate at
different voltages. If the cell in one module failed, it would
disconnect itself from the bus instead of dragging it down.

He found it a challenge to achieve high efficiency in the DC-DC
converter with low voltage batteries. For the lower voltage chemistries
(e.g., NiMH at 1.2 V) it might be necessary to compromise by using two
or maybe three cells in series per module. A lithium ion module would
need only one cell since they operate at a much higher voltage of 3.6V.

The beauty of his scheme is that not only would this be far more robust
against individual cell failures than a single series string, you could
fly several kinds of batteries to see which functions best.

With the proper command to a module controller you could perform a
controlled discharge of its cell for a capacity test. That’s kinda neat.

Some modules could use supercaps. They have very high cycle lives
(~500,000) but low energy density (0.35 watt-hour for a D-cell sized
cap). You’d always discharge them first, or perhaps keep one in reserve
to keep a computer going. Since they’re capacitors you’d need the DC-DC
regulator to produce a constant voltage as they discharge.

Thinking more about his scheme, you could program each module with a
command like “Keep the power bus at +12V by pumping up to 2A into it
until you’re 50% depleted” or “charge at 1A max unless the bus voltage
falls to 11.5V”. The computer could issue a new command at any time,
such as one to stop all charging when the satellite enters eclipse.

One module might contain just a load resistor to act as a shunt
regulator to keep the bus voltage from going too high.

And one or two modules might contain high-density (e.g., lithium)
primary batteries as emergency fallbacks to keep things going long
enough for the command stations to figure out what’s going on.

The ARISSat-1 battery performed as expected during the first week of
operation. Lower voltages during eclipse began to show up in the
telemetry on 10 Aug 2011. The voltages during eclipse have continued
to decline causing the satellite to reset and go into Emergency Power
Mode on 12 Aug. After reset, the satellite MET (Mission Elapsed Timer)
goes to 000, waits during the 15 minute TX delay, the power management
software checks the current voltage and power values and determines
what power mode to operate the satellite. The power mode is
re-determined at fixed intervals, especially during illuminated
periods to provide the most transmitted signals while protecting the
battery.

Additional information and explanation about the workings of the
ARISSat-1/RadioSkaf-V power system can be found on the arissat1.org
web site under the FAQ section.

The ARISSat-1 team is closely monitoring the situation and is pleased
with how well the power management software is controlling the battery
usage to prolong the lifetime of the battery and the satellite as much
as possible.
