A Minotaur-4 launch from the Kodiak Launch Complex in Alaska, =

managed by Alaska Aerospace Corp. on November 19 lifted seven
satellites into a 400 mile high circular orbit.

Four of the satellites will be of interested to amateur radio
operators:

+ FASTRAC (science and amateur radio mission)
+ RAX - Radio Aurora eXplorer (science and amateur radio mission)
+ NanoSail-D
+ O/OREOS

FASTRAC
-------
http://fastrac.ae.utexas.edu/for_radio_operators/overview.php
Status: Beacon copied and decoded after launch.

The FASTRAC mission consists of two satellites built by students =

at UT-Austin. This mission is divided into two basic phases, both =

phases relying heavily on the participation of the amateur radio =

community.

The first phase is the science portion of the mission. During this =

phase the two satellites will be sharing GPS data as long as they =

are within range of each other. The GPS data will be processed on =

board each satellite and then stored in flash memory to calculate =

an on-orbit relative navigation solution. =


Also, the satellites will be performing attitude determination with =

the GPS receiver. FASTRAC 1 will be firing the micro-discharge plasma =

thruster whenever the thrust vector is within 15 degrees of the anti-
velocity vector. The data will be relayed to the ground when the sat-
ellite is in communication with a ground station. A coordination plan =

is being developed so that participating amateur radio ground stations =

can play a major role in collecting this data and relaying it back to =

the FASTRAC web site.

The second phase of the mission begins by reconfiguring the satel-
lites for use by the amateur radio community. The capabilities of =

these satellites are governed largely by the functionality of the =

Kantronics KPC9612-Plus TNC. The satellites will be reconfigured =

after the primary mission to serve on the APRS network.

                FASTRAC 1 "Sara Lily"      FASTRAC 2 "Emma"
                ---------------------      ----------------
Downlink           437.345 MHz FM           145.825 MHz FM
Beacon             437.345 MHz*             145.825 MHz* =

Uplink (1200 Baud) 145.980 MHz FM           435.025 MHz FM
Uplink (9600 Baud) 145.825 MHz FM 	        437.345 MHz FM
* AX.25 1200 AFSK beacon data format

RAX (Radio Aurora eXplorer)
---------------------------
http://rax.engin.umich.edu/
Status: Beacon copied and decoded after launch.

RAX is a space weather science spacecraft carrying a 9600 baud UHF =

transceiver that will transmit telemetry in the amateur satellite =

bands. This mission also consists of a primary scientific experiment
with future reconfiguration for amateur radio experimentation.

In the science phase the satellite will use a a radar receiver capable =

of 1 MHz I/Q sampling of select bandwidths between 400-500 MHz, includ-
ing the amateur satellite bands. =


The primary objective of the mission is to use the onboard radar rece-
iver in conjunction with a powerful radar station in Alaska to study =

the formation of a plasma anomaly known for causing the scintillation =

of radio signals in the UHF and higher bands. This scintillation effect =

is known to inhibit our space radar tracking capabilities and ground-
space communications. =


The RAX team is looking for amateur ground stations to help acquire =

RAX's 437.505 MHz beacon during the next few weeks of early launch and =

continue to help collect telemetry throughout the mission.

The amateur radio phase of the mission is still under development. The
RAX team will invite the AMSAT community to get involved with submit-
ting proposals on how the radar receiver could be used for amateur radio =

experiments after the primary mission objective is achieved. They will
issue a call for proposals which will be posted to the AMSAT-BB in the =

next few months.

NanoSail-D
----------
http://www.nasa.gov/mission_pages/smallsats/nanosaild.html

NanoSail-D is a test of solar sail mechanism technology. The solar
sail is designed to operate predominantly as a drag sail and will =

cause it to de-orbit in less than 100 days as a test of small
satellite de-orbiting techniques. The amateur radio beacon will
transmit a one-half second data signal every 5 seconds on 437.270 MHz.
The satellite will operate primarily on battery power because of the
short duration of the mission.

O/OREOS
-------
http://www.nasa.gov/mission_pages/smallsats/oreos/main/index.html
Status: Beacon copied and decoded after launch.

O/OREOS is a biological test spacecraft developed by scientists and =

engineers at NASA Ames Research Center.  O/OREOS is a triple cube =

spacecraft planned to perform two tests during its 1-year mission.  =

The first experiment will test how microorganisms survive and adapt =

to the stresses of space; the other will monitor the stability of =

organic molecules in space. O/OREOS includes an amateur radio beacon =

operating on 437.305 MHz. This satellite also includes a novel de-
orbit mechanism design by a Santa Clara University graduate student.

AX.25 437.305 MHz O/OREOS Beacon decoding information:
http://beacon.engr.scu.edu/BeaconProcessingSystem/OOREOSBeaconDecoding.pdf

If you are able to capture the beacon telemetry, please take the time
to file a report at http://beacon.engr.scu.edu/Submission.aspx which
is an interface to the Beacon Data Processing System.

AMSAT-VP Operations Drew Glasbrenner, KO4MA announced AMSAT is now
using a new web based fund raising tool on Facebook called Fundrazr
along with a web widget from PayPal Labs you can add to other web
pages. He hopes this will stimulate additional fund raising support =

for ARISSat-1 and AMSAT-FOX. He is looking for help rolling these =

web page widgets out to the public. Both are designed to be spread =

virally and attract donations from those outside the normal AMSAT =

circles.

For those with private webpages or blogs, we have a PayPal widget that =

can also be added to your own webpages and blogs. It has been added to
the front page at http://www.amsat.org . Please consider adding it to =

your own webpages and blogs in a prominent place.

Drew concludes, "I'm proud to announce that the Facebook and PayPal =

widget campaign has raised $1,000 over the last 48 hours! This is a =

great first step towards replenishing the funds used in the construc-
tion of ARISSat-1, and beginning the design and construction of =

AMSAT-FOX. Thank you to those who posted the fundraiser to their own =

pages, and to those who donated."

Drew's Facebook page at http://bit.ly/c861N7 now prominently includes
the Fundrazr widget that you can share or post. Drew has also added =

the PayPal Labs widget on his QRZ.com entry, see: =

http://www.qrz.com/db/KO4MA or http://www.qrz.com/db/K9JKM

For the FundRazr app on Facebook, go to Drew's Facebook page and click =

share. For the PayPal widget on all other web sites, use the "add to =

site" button. It will prompt you how to do it. It also lets AMSAT see =

who and where it has been posted, and how much money has been raised =

from each location.

Please let Drew know if you add either of these so he can track results!

The UK Martlesham Microwavers Round Table weekend also included an
AMSAT-UK FUNCube developer meeting. The aim of the working session
was to build a `stack' of the various boards which will make up FUNcube =

and see if they worked! =


Congratulations are in order to the FUNCube team being able to report =

success on these milestones:

+ Prove that we could command the satellite remotely via RF.
+ Receive and examine the telemetry from the stack remotely using the =

  FUNcube dongle.
+ Command the antennas to deploy.
+ Command the satellite to change modes between transponder mode to =

  education mode, and back again.

The main 'new' PCBs that arrived were David's PA, Wouter's RF board, =

and the CCT board from Jason and his team.

Photos of the meeting and FUNCube construction and testing videos can
be viewed on-line at:
http://funcube.org.uk/working-meetings/cubesat-mtg-1314-nov-2010/ =


A screenshot of the first captured telemetry from FUNCube can be seen
on-line at: http://www.funcubedongle.com/?p=3D195

The Spectravue plot to the right shows the satellite's downlink received =

using a FUNcube Dongle. To the right hand side of the plot, the solid =

green `hump' is the telemetry and the signal to the right of that being =

simultaneous transponded SSB voice traffic. =


To the bottom left, old hands will recognise the AO-40RCV window being =

used to decode raw frames. The basic telemetry specification is based =

heavily on AO-40's FEC model.
