*Nya Cubesats ute från ISS

Five CubeSats Deployed From ISS Now on-Orbit – Signals Received
Five cubesats launched on July 21 and loaded aboard the ISS were
integrated with the J-SSOD small satellite deployer on the the
Japanese Experiment Module, also known as Kibo. They were deployed
with the Kibo robotic arm on October 4, 2012. The orbit for these
CubeSats will be very close to the orbit of the ISS.

FITSAT-1 Heard With Strong Signals
———————————-
Signal reports from PY5LF, OH3UW, DK3WN, VU3TYG, G6LVB (using a FUN-
cube Dongle Pro+ and 7″ wire antenna), GW1FKY, F5YG, JE9PEL, JN1GKZ,
ST2NH, and others via the amsat-bb list.
FITSAT-1 transmits its beacon frequency 437.250 MHz. This is the
same frequency as the PRISM satellite of Tokyo Univ. FITSAT CW will
transmit, “HI DE NIWAKA JAPAN” with its telemetry data. To receive
a FITSAT-1 QSL card please send your signal report and your postal
address to: fitsat1@hotmail.co.jp and also cc to tanaka@fit.ac.jp.
A photo of the QSL card is shown at:
http://www.fit.ac.jp/~tanaka/fitsat.shtml
This web page will also be updated with information about the status
of the LED experiment.
HB9FFH has made a telemetry decoder for FITSAT-1, available at:

FITSAT students have also developed a similar program for windows:

TechEdSat Heard With Weak Signals
———————————
Signal reports received from PY5LF, DK3WN, and JE9PEL indicate that
TechEdSat was received with weak signals on its 437.465 MHz downlink.
Mark Allard, KD6CWM, President of the NASA-Ames Research Center Ama-
teur Radio Club reports their OSCAR/ARISS satellite station, NA6MF,
will be supporting TechEdSat as one of the monitoring stations for
the TechEdSat Amateur Radio beacon.
TechEdSat transmits a custom beacon packet. Details can be found at:
http://www.techedsat.com/. Packets acquired from TechEdSat can also
be submitted to the website for decoding by the TechEdSat team. Use
the ‘Packet Submission’ link found at the top of the web page.
WE WISH SSTV Picture Received
—————————–
PY4ZBZ and JE1CVL received the SSTV picture on 437.505 MHz.
JE9PEL provided a translation of the image that is a sentence of
“JQ1ZIJ MEISEI ARC 2012”. A photo of the received picture is at:

Viet Nam F-1 Not Heard
———————-
Viet Nam’s F-1 satellite was scheduled to begin telemetry transmis-
sions 30 minutes after deployment by sending a beacon alternating on
its main and backup channels. At press time no signal reports have
been received from this satellite.
More information and guide to download F-1 telemetry decoder can be
found at http://fspace.edu.vn/?page_id=27. Decoded data can be sub-
mitted via the telemetry decoder or by sending directly to the ground
station: thuvt@fpt.edu.vn. Audio recordings are highly appreciated.

*PSK-31 transponder
US Naval Academy PSAT Features PSK-31 and APRS Transponders
The US Naval Academy in Annapolis, Maryland is developing a new
student satellite, ParkinsonSAT, or PSAT which is a two way APRS
communications transponder for relaying remote telemetry, sensor
and user data from remote environmental experiments or other data
sources back to experimenters via a global network of internet link-
ed volunteer ground stations. The data transponder also includes all
telemetry, command and control for a complete cubesat.
PSAT is a 1.5 unit cubesat so that two PSATs can be launched from
the same P-Pod launcher. The design uses four deployable solar ar-
rays which are stowed down the sides. Half of the 1.5 unit PSAT is
available for auxiliary payloads or experiments. Details of the
PSAT project are available on-line at: http://www.aprs.org/psat.html
PSAT will fly a PSK-31 transponder with a 10 meter uplink and a 2M
FM downlink. PSK-31 will allow up to 30 simultaneous users:
http://aprs.org/psat/PSK31-DESIGN-NOTES.html
Bob Bruninga, WB4APR noted, “PSK-31 is the ideal AMSAT FM trans-
ponder for a cubesat. With an FM downlink, anyone can receive it
with an HT and a laptop with PSK-31 software. And anyone with a
10m PSK-31 uplink can transmit to it. And since the downlink is FM,
everyone tuned in SEES THE SAME WATERFALL and sees EXACTLY where
they are in the downlink. A small uplink doppler adjustment can keep
each station locked to his chosen channel in the passband. Everyone
can talk to everyone if they want, or go one-on-one too.”
The SSB uplink and UHF FM downlink transponder fits on a smaller than
3″x3″ circuit board being developed by Mirek Kasal at Brno University.
Launch of PSAT is planned in 2015. The 3″x3″ transponder may also be
adaptable for other missions.
