ARISSat-1/KEDR Goes Silent
Reception reports indicate that ARISSat-1/KEDR has stopped trans-
mitting on Wednesday, January 4, 2012. The last full telemetry =
captured and reported to the ARISSatTLM web site at 06:02:14 UTC =
on January 4 were received from ground stations as the satellite =
passed over Japan.
See: http://www.arissattlm.org/live (full telemetry display)
See: http://www.arissattlm.org/mobile (condensed telemetry)
Telemetry reports showed that the temperature aboard ARISSat-1/KEDR =
had been rising as atmospheric drag began to affect the satellite.
Final temperatures received via ARISSatTLM reported this data:
IHU 75 =B0 C / 167.0 =B0 F
PSU 76 =B0 C / 168.8 =B0 F
RF 88 =B0 C / 190.4 =B0 F
Control Panel 61 =B0 C / 141.8 =B0 F
Experiment 64 =B0 C / 147.2 =B0 F
Tracking data from Space Command gave a Predicted Decay Time 0700 GMT =
+/- 3 Hours on January 4. Telemetry report narrows the impact time =
window to about 4 hours. The predicted decay location is 12.7=B0 S, =
354.3=B0 E, an open part of the South Atlantic, well west of Angola. =
Send reports to the amsat-bb If you heard the satellite, even briefly, =
after 0600 UTC. This will help confirm the actual impact point.
Stations receiving telemetry from ARISSat-1 at any time over the =
last few months, please forward all of your .CSV telemetry files =
to telemetry AT arissattlm.org.
Konstantin, RN3ZF sent a reception report of his copy of the 0842 UTC =
pass that, "the telemetry was absent, voice messages were not legible, =
very silent and interrupted. Most likely, I saw last minutes in the =
life of the satellite."
Dee, NB2F reported, "Nothing heard from ARISSat-1/KEDR on any fre-
quency during the first USA pass at 16:00 UTC, January 4."
ARISSat-1/KEDR was deployed from the International Space Station on
August 3, 2011 during during EVA-29 on by Cosmonaut/Flight Engineers =
Sergei Volkov and Alexander Samokutyaev.
The satellite carried a student experiment from Kursk State University
in Russia which measured atmospheric density. Students from around the
world provided the voices for the FM voice announcements.
The amateur radio payload aboard ARISSat-1/KEDR achieved many "firsts"
for amateur radio in space:
+ First flight test of AMSAT Software Defined Transponder which trans-
mitted simultaneous:
=
- FM voice downlink cycling between student messages, spoken
telemetry and SSTV from cameras on the spaceframe.
- 16KHz bandwith linear transponder, =
- CW beacon with telemetry and callsigns of radio amateurs noting
their significant contributions to amateur radio in space.
- Robust, forward error corrected 1K rate BPSK downlink with sat-
ellite telemetry and Kursk experiment telemetry.
+ Development and release of the ARISSatTLM software for PC and Mac
platforms enabled amateur stations worldwide with reliable reception
of the BPSK telemetry, CW telemetry, display on the station's com-
puter, and automatic upload of received data via the internet to the
ARISSat engineering team.
+ A new Integrated Housekeeping Unit was developed and successfully
flown.
+ A new Power Management System was developed and successfully
flown.
AMSAT President Barry Baines, WD4ASW noted, ARISSat-1/KEDR marked a =
new type of satellite which has captured the attention of the national =
space agencies around the world for the unique educational opportunity =
we have been able to design, launch, and operate. By designing an edu-
cational mission aligned with NASA's Science, Technology, Engineering, =
and Mathematics goals amateur radio operators around the world have =
been able enjoy a new satellite in orbit."
ARISSat-1/KEDR Project Manager, Gould Smith, WA4SXM said, "Dozens of =
amateur radio volunteers, AMSAT, ARRL, NASA, and Energia teamed up for =
this successful mission to bring you the most unique and innovative =
amateur radio satellite mission. Congratulations to all who made =
ARISSat-1 successful!"

FUNcube - Launch Details and Time Frame Finalized
An agreement has now been reached with ISIS Launch Services BV, who =
are based in Delft in the Netherlands, for them to provide a launch =
of the FUNcube-1 CubeSat.
It is anticipated that FUNcube-1, which has been created by a team =
of volunteer radio amateurs and other specialists over the past two =
years, will be launched with a number of other spacecraft from a =
DNEPR rocket sometime in the third quarter of 2012. The flight is =
planned to take place from the Yasny launch facility which is in =
southern Russia near to the Kazakhstan border. The spacecraft needs =
to be completed by the end of July 2012, ready for shipping from =
the Netherlands to Russia.
The orbit is still to be defined precisely but it is expected to be =
nearly circular and approximately sun synchronous. This will ensure =
that the spacecraft has the necessary solar illumination and that =
it will appear at regular times for educational outreach activities =
at schools and colleges.
The FUNcube-1 spacecraft will transmit signals that can be easily =
received directly by schools and colleges for educational outreach =
purposes. This telemetry will give details of the spacecraft's health
- battery voltages and temperatures and from this it will be possible =
to determine its spin rate and attitude by plotting simple graphs. =
Additionally, experimental data and messages can be displayed in an =
attractive format and provide stimulation and encouragement for stu-
dents to become interested in Science, Technology, Engineering and =
Mathematics (STEM) subjects in a unique way.
The target audience for this project is students at both primary and =
secondary levels and a simple and cheap "ground station" - actually =
it looks just like a USB dongle, for schools to use, has already been =
developed.
In addition to providing educational outreach for schools and colleges =
around the world, the spacecraft will also provide a U/V linear trans-
ponder for radio amateurs during local "night", at weekends and during =
holiday periods.
The IARU amateur satellite frequency coordination panel has announced =
new frequencies for the FUNcube-1 satellite to take into account other =
payloads on the same launch. The new frequencies are:
FUNcube-1 New Frequencies
-------------------------------
Uplink 435.080 - 435.060 MHz
Downlink 145.960 - 145.980 MHz
Beacon 145.955 MHz CW and BPSK.
The production and testing of the spacecraft itself has already been =
funded via a legacy and other sources. It will however really help =
the project if radio amateurs and other interested supporters could =
contribute something towards the cost of the actual launch itself. =
With this in mind a special donation scheme has been setup using the =
Virgin Giving charity donation website.
All donations received from UK tax payers can be "Gift Aided" which =
will add 20% to the value of your donation.
More information about this exciting project will be made available =
over the coming months at the FUNcube website.

DNEPR Launch Includes Triton-1 and Triton-2 Amateur Satellites
AMSAT-UK reported this week that the same DNEPR launch in the third =
quarter of 2012 carrying FUNcube-1 will also have additional amateur
satellite payloads aboard.
Triton-1
--------
Comprising of a 3U CubeSat, the Triton-1 mission is a radio science =
mission which aims to test an experimental advanced AIS (Automatic =
Identification System) receiver.
Telemetry decoding software will be made available which will allow =
radio amateur operators to listen to periodic downlink broadcasts =
containing housekeeping telemetry, payload telemetry as well as re-
ceived AIS messages. Telemetry downlinks will be 9k6 RC-BPSK on VHF =
(145MHz). =
The satellite also includes two similar secondary amateur radio pay-
loads, being two single channel mode U/V (435-145MHz) FM to DSB =
transponders.
After the Triton-1 three month science mission is complete plans are
to have the satellite continue in the Amateur Satellite Service for =
as long as possible.
The following downlink frequencies have been coordinated for Triton-1:
=
Main Downlink 145.815 MHz =
Backup Downlink 145.860 MHz
Uplink frequencies will be announced by the project team once the
satellite becomes available for amateur operations.
Triton-2
--------
Comprising of a 3U CubeSat, the Triton-2 mission is a radio science =
mission which aims to test an experimental advanced AIS (Automatic =
Identification System) receiver. =
Telemetry decoding software will be made available which will allow =
radio amateur operators to listen to periodic downlink broadcasts =
containing housekeeping telemetry, payload telemetry as well as re-
ceived AIS messages. Telemetry downlinks will be 9k6 RC-BPSK on VHF =
(145MHz) and 38k4 RC-BPSK on S Band (2400MHz). =
After the Triton-2 three month science mission is complete plans are
to have the satellite continue in the Amateur Satellite Service for =
as long as possible. The satellite includes two secondary amateur =
radio payloads: =
+ A single channel mode U/V (435-145 MHz) FM to DSB transponder.
+ A single channel mode U/S (435-2400 MHz) FM to FM transponder.
Downlink frequency details will be published shortly. Uplink fre-
quencies will be announced by the project team once the satellite =
becomes available for amateur operations. Power budget permitting, =
both payloads may be switched on at the same time.
In addition to Funcube, Triton-1, and Triton-2 this DNEPR rocket will
launch UKube-1, Delfi n3Xt (also carrying a linear amateur U/V linear
transponder), Trio-Cinema 1 & 2 and other spacecraft using frequencies =
in the amateur satellite service.

FUNcube Dongle Presentation Video
The AMSAT-UK FUNcube Dongle is a VHF/UHF (64-1700 MHz) Software Def-
ined Radio (SDR) on a USB Dongle. Howard Long G6VLB traveled from =
London to the 2011 ARRL/TAPR Digital Communications Conference (DCC) =
in Baltimore to address the group on this project. He details the =
trials and tribulations behind designing and manufacturing what =
turned out to be an extremely popular product.
The primary aim of the FUNcube Dongle is to interest young students =
in science, satellites and radio. The FUNcube itself is a satellite =
that will be launched specifically to be monitored by all those =
dongles that have been sold.

Ham Radio Builder List Begins
If you are currently a ham radio builder, or interested in becoming =
one, the Hamradio-builder mailing list has been created with you in
mind.
Diane Bruce, VA3DB says of the list, "A recent look at some old 73 =
Magazines brought to mind the simple projects this magazine produced. =
So my thought was to do something similar, but meant for the web in-
stead of dead tree. I am not talking a full fledged magazine, but a =
website where we can put simple beginner type articles, with copious =
photos and good instructions. We hope it will become a bit like Maker
Magazine but for the radio amateur."
A few of us have written and edited amateur radio articles. She is =
proposing for the moment that we clean up or write a few articles =
suitable for beginners to start the content for this community.
List members have already proposed topics on homebrew test equipment,
and antennas. Amateur satellite operators have skill and many ideas,
construction projects, and techniques to get beginners on-the-air at =
VHF, UHF, and microwave frequencies.
The project is just getting started. If you are interested in joining
this community you can sign up for the list at:

Creation of AMSAT-Francophone
A new amateur radio satellite organization, AMSAT-Francophone, was =
formed in December, 2011.
Following the disappearance of AMSAT-France a few months ago, some of =
the members who originally created AMSAT-France 16 years ago, thought =
it was still necessary to have a structure for the French amateur =
space activities and have created AMSAT-Francophone.
Among its aims are:
+ Development of amateur satellites, technology and systems useful =
for the construction and / or use of amateur satellites
+ Participation in national and international collaborations on =
non-commercial projects in space,
