BID: $ANS-354.01

Amateur satellite operators worldwide have reported receiving strong
signals on the telemetry beacon of China's XW-1 satellite launched 
on December 15, 2009.

The satellite is currently being commissioned but all three amateur
radio modes, which include an V/U FM repeater, V/U linear transponder,
and V/U AFSK packet, have been tested.

Michael Chen, BD5RV/4 reported, "I managed to operate the special 
event station BT3WX to work several E2, BY, VR2, XX9 throughout an 
evening pass of XW-1 using the FM transponder. It was the first open
test of this bird's transponder. Everything works just great!"

AFSK packets were active over Japan with JA0CAW receiving the down-
link on 435.675 MHz AFSK 1200bps.

JE1CVL, JH1EKH, BD4SY, JF2CTY, JH1BCL, JA5BLZ succeeded in a QSO over
Japan using the linear transponder in 'VHF(LSB) up and UHF (USB) Linear 
Transponder Inverting on 145.950 MHz (Up) and 435.740 MHz (Down).

The XW-1 communications payload includes a beacon and three cross 
band transponders operating in FM, linear, and digital modes. 

Uplinks:   145.8250 MHz FM, PL 67.0 Hz.
           145.9250 - 145.9750 MHz SSB/CW
           145.8250 MHz AFSK 1200 BPS

Downlinks: 435.6750 MHz FM
           435.7650 - 435.7150 MHz SSB/CW
           435.6750 MHz AFSK 1200 BPS

Beacon:    435.7900 MHz CW

of the beacon: http://tinyurl.com/yjgett6

XW-1 was a secondary payload aboard the CZ-4C rocket from Taiyuan 
Satellite Launch Center into a sun-synchronous orbit about 1200 
kilometers high. The primary payload of this launch is the Yaogen-8 
Remote Sensing Satellite. 

BD5RV/4 requests amateur radio operators send him audio recordings, 
notes on received content, your QTH, callsign, date/time of the XW-1 
beacon you heard to AMSAT China by email. Later, you'll be able to 
upload it via web, but for now, email works. Send your files and

AMSAT-NA and the AO-51 Operations Group will sponsor Kid's Day on 
AO-51 on January 3, 2010. The event is open to all kids, worldwide. 

We ask all amateur radio stations to give this short time window to 
promote satellite operations with kids, by actually showing a kid how 
to make contacts via AO-51, providing a station to contact, or stepping 
aside to allow others to make contacts with the kids. During the event, 
please limit contacts to stations that are operating with kids at the 
microphone. This should allow the kids to have a nice QSO and pass some 
information. Kids can tell their name, age, who is helping them operate 
on AO-51, where they live, and other information about themselves. 
 
AO-51 will be configured in the following mode during the event. 
Uplink:   145.880 MHz FM voice 
Downlink: 435.300 MHz FM voice 
 
See http://www.arrl.org/FandES/ead/kd-rules.html on the ARRL 
website for more Kids Day information. 
 
Have fun and enjoy AO-51!

On 3 February 2006, cosmonaut Valery Ivanovich Tokarev hand launched 
the  Amateur Radio satellite SuitSat-1 from the ISS during an EVA 
(Extra Vehicular Activity = Spacewalk).

SuitSat-1 was a very special Amateur Radio satellite. A discarded 
Russian ORLAN Space Suit (in Russian a "Skafander") was equipped with 
an Amateur Radio transmitter, which transmitted telemetry and 
greetings from youngsters to the youth of the world in several 
languages.

In 2010, an Amateur Radio satellite will once more be hand launched 
from the International Space Station. It will be called ARISSat-1.

ARISSat-1 will again transmit messages recorded by students. 
Moreover, teachers and students are invited to fly a file aboard this 
amateur radio satellite.

The ARISSat-1 Team wishes to include on our new satellite a memory 
stick of files prepared by students.  This should be a jpg or pdf of 
things the student has prepared such as a paper or a study done on a 
STEM (science, technology, engineering, math) topic, a drawing of 
space craft or a schematic, a journal kept on a STEM topic, a story 
or news article about a STEM subject, a photo of the class doing a 
hands-on STEM activity -- that type of thing.

Having the student's work be a part of ARISSat-1 means the student is 
a part of the satellite project and along for the spacewalk and 
deployment of ARISSat-1.

Readers of this Bulletin are invited to approach teachers and 
students and draw their attention on this opportunity to participate 
directly to a space flight for the honor of being part of space 
activities.

Dave Jordan, AA4KN, will take delivery of these files and copy them 
onto a memory stick. The quantity of files and the size of a file are 
unlimited since memory sticks provide for a very large amount of file 
space.

Files should be either .JPG or .PDF  -- no Word documents, please.
Please send files to Dave Jordan's address -- <aa4kn at amsat.org>
He will look at all of them for content appropriate to students.

Files can be in any language as long as an English translation is 
also included as a text file.

If the file contains sound recordings and/or photos or names of 
persons, a "Talent Authorisation and Release" is requested. The 
appropriate document can be downloaded from
http://www.rac.ca/ariss/Talent_Release.htm

The permission slip has to be signed by the student or his/her 
guardian if the student is a minor.

The signed release form is to be mailed to:
AMSAT
Martha Saragovitz
850 Sligo Ave. Suite 600
Silver Spring, MD 20910

Deadline for submitting files: March 1st, 2010.

NASA Revised EVA Schedule Affects ARISSat

AMSAT News Service Bulletin 354.05

BID: $ANS-354.05

NASA has informed AMSAT that the schedule of work for EVAs at the 
International Space Station is being revised.  The planned deploy-
ment of ARISSat-1 from the ISS is now being scheduled for either 
Fall 2010 or early 2011 rather than Spring 2010.  

This schedule adjustment also impacts when ARISSat-1 will be flown 
to the Space Station with upload likely to take place sometime in 
Summer 2010 rather than in January. 

These revisions were made in response to new higher priority work 
that must be done during the timeframe of the EVA that ARISSat-1 
was originally scheduled in April 2010.

Overall, this revision helps ARISSat-1 because it provides additional 
time for testing of the spacecraft.  Furthermore, it also ensures 
that the NASA Safety Review process for ARISSat-1 can be concluded 
prior to shipment of the spacecraft to Russia.

The major items to complete for ARISSat are the IHU software, PSU 
software, PSU testing and system testing. The structure is coming 
together well and the team looks forward to providing an innovative 
and reliable satellite this coming spring.

ESA and CNES to Fly Atomic Clock to ISS Columbus Module

AMSAT News Service Bulletin 354.07
>From AMSAT HQ SILVER SPRING, MD.
December 20, 2009
To All RADIO AMATEURS
BID: $ANS-354.07

The French space agency (CNES) and ESA have signed an agreement 
that paves the way for the launch of a high-accuracy atomic clock 
to be attached to the outside of the European Columbus laboratory 
onboard the International Space Station (ISS).

The PHARAO (Projet d'Horloge Atomique par Refroidissement d'Atomes 
en Orbite) atomic clock, which will be combined with another atomic 
clock, the Space Hydrogen Maser (SHM), to form ESA's Atomic Clock 
Ensemble in Space (ACES), will have an accuracy of 1x10-16, corres-
ponding to a time error of about one second over 300 million years.

This new generation of atomic clocks in space will be instrumental 
in enabling accurate testing of Einstein's theory of general rela-
tivity. In addition, it will contribute to the accuracy and long-
term stability of global timescales, such as Coordinated Universal 
Time (UTC). A dedicated microwave link will send the timing signal 
to the ground.

The atomic clock is designed for launch in the unpressurised cargo 
bay of the Japanese H-II Transfer Vehicle (HTV) or commercial SpaceX 
carrier in the second half of 2013. Once in orbit, it will be attached 
to Columbus' Earth-facing external payload platform using the Station 
Robotic Arm.
