The launch of Auburn University’s AubieSat-1 satellite has been rescheduled to
28 October 2011 due to problems found during the system integration of the
primary mission. A hydraulic system leak was detected and the cause was found to
be a small crack in a hydraulic tube. A replacement tube was manufactured,
installed, and retested. Also, a flexible fabric collar connecting two engine
system exhaust ducts was found to be damaged following pressurized leak testing.
The damaged
fabric collar is being removed and replaced.

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

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.

Auburn’s famous battle cry, “War Eagle,” will be heard from space October 28
when it is transmitted to earth from a student-built satellite known as
“AubieSat-1.” Auburn University’s web page includes a video about their mission:

Radiomjukvaran SDR-Radio stödjer nu även USB-radio FUNCube Dongle med bla. trackingmöjligheter för satelliter. Hela nyheten här:

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
http://www.sdr-radio.com/

The UK Smartphone CubeSat STRaND-1 will carry an Android Smartphone and plans to use data rates of 9k6 or 19k2 bps for the AX.25 packet radio downlink. A software-based speech synthesiser will be included to pay homage to the UOSAT family of satellites.

The 3U CubeSat measures 30 by 10 by 10 cm and weighs 3 kg. Unlike previous CubeSats it will feature full 3-axis control with the attitude an orbit control system comprising a nano-magnetorquer, nano-reaction wheels, GPS receiver, 8 pulse plasma thrusters and a butane thruster.

Hej!

*ARISSat-1
Satelliten sänder fortfarande på 145.950. fina passager på kvällarna med
många bilder

*Soyuz uppskjutningsproblem.

I veckan gick en del proviant och reservdelar till instrument förlorade då
en av dom annars så tillförlitliga raketerna fick problem med ett steg och
kunde ej nå sin bana på väg till ISS.

*SO-67
Satelliten har fått problem och vi avaktar mer infromation

*AO-51
En andra cell i batteripacken är på väg att ge upp och nu blir det mer och
mer aktuellt med FOX satelliten som ska ersätta den populära FM satelliten.
Det verkar som att FOX ska delas upp i FOX-1 samt FOX-2 ( FOX-1 ska snabbt
ersätta AO-51.)

*HO-68
Hörs bara beacon och ingen information. (Nu verkar även hemsidan ha
försvunnit,,,)

*Asteroid ( Se upp,,,)

En rolig utmaning framåt hösten att höra ekona från asteroiden när den drar
förbi jorden.

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:
http://echo.jpl.nasa.gov/asteroids/2005YU55/2005YU55_planning.html
More details will be announced as the fly-by date approaches.

En god vecka tillönskas!
