Delfi-C3 DO-64 Tests Linear Transponder

BID: $ANS-145.02

During the past week the Delfi-C3 satellite DO-64 has continued
its science mission.  But, during a pass over the Delfi-C3 ground
station on May 15 the amateur band linear transponder was success-
fully tested and activated for a short time. The CW beacon was 
received well and subsequently good signals using SSB were received. 
An audio file of the test can be found at:
http://www.delfic3.nl/photoblog/wp-content/uploads/2008/05/pe4wj_transponder
_test.mp3

The Delfi ground control team is currently performing tests while 
the spacecraft is over the Netherlands to address the downlink drop-
out issue. These tests may require several passes over the ground 
controllers so the satellite may still experience downlink dropouts 
over the coming days.

The current operating mode of Delfi can be found on its webpage at:
http://www.delfic3.nl/index.php?option=com_content&task=view&id=93&Itemid=12

While in science mode Defli has continued operation on a downlink of
145.930 MHz, transmitting 1200 Baud BPSK AX.25 telemetry data.  Reminder:
Delfi-C3 does not have a battery on-board and will therefore only be 
active in sunlight.  The latest keplerian elements for Delfi can also
be found on the operations web page.

The Delfi team reported, "Up to now, we have received over 130000 
AX.25 frames from all over the world, thank you very much for your 
efforts and observations so far!"

Global Packet Operation Activated on Cute1.7 + APD II

BID: $ANS-145.03

Hiroki Ashida, JQ1YCZ reported this week that the Tokyo Institute of 
Technology enabled continuous packet telemetry on their cubesat,
Cute1.7 + APD II.  This was to support a 12 hour experiment of the
Avalanche Photo Diode APD) as a radiation monitor of low-energy 
(E > 10 keV) particles trapped in low Earth orbit.

Prior to the activation of this experiment packet telemetry had 
only been activated when the Cute1.7 + APD II cubesat was within
range of the Japanese ground control station.

The FM packets were received on 437.475MHz from amateur radio station
around the world. Packet formats and additional satellite information
can be found at:

AO-16 Operation Update

BID: $ANS-145.04

Mark Hammond, N8MH, AO-16 Command Station gave an update of testing on
the AO-16 satellite.  Mark commented, "Indeed, over the last several 
days you are likely to have found AO-16 silent.  There appears to be 
something in the spacecraft shutting down the transmitter after a 
short, random period of time.  Current speculation on the problem in-
cludes a temperature issue that has reared its ugly head now that the 
eclipse periods are increasing and the spacecraft internal temperatures 
are decreasing.  It may be a hardware timer.  It does not appear to be 
a battery issue."

The ground control station will  manually turn the satellite ON and 
then configure it for voice operations.  This is a manual process 
and command stations are limited to the East coast of the US.  As 
schedules permit, we'll try to turn it ON; for now, it's the best 
we can do. Time will tell if the current situation will stay the 
same, improve, or get worse.

China Plans Amateur Radio Satellite Launch

BID: $ANS-145.05

A report has been received via Michael Chen, BD5RV/4 that a new 
amateur radio satellite to be launched by China, CAS-1 has completed 
its IARU frequency coordination and the hardware has been finished.

The payload is planned to include a CW Telemetry Beacon, Linear Trans-
ponder, FM repeater and a Digital Store-forward Transponder. The oper-
ations will use 70cms downlinks and 2 meter uplinks at 500mW output 
power. The satellite is expected to have a mass of 30kgs and be 
launched from China into a sun syncronous orbit with a 670km apogee.

The CAS-1 team is waiting for another payload to be finished before 
launch which at this point is predicted to happen in early 2009.

AO-51 will switch into dual V/U repeater mode UTC May 26, 2008.  Take 
advantage of the secondary repeater for historically easier operation.  
Information about the AO-51 modes and frequencies can be found on the 
AMSAT web site.

Yubileiny RS-30 Launched on May 23

AMSAT News Service Bulletin 145.08

BID: $ANS-145.08

The Russian Federal Space Agency announced the successful launch of 
the Yubileiny, a 45 kg small satellite, on May 23 from the Plesetsk
Launching Site into low earth orbit.

The motive for development of Yubileiny small spacecraft was the 50th 
anniversary of the first space satellite. One mission goal includes 
flight qaulification of the new space systems and equipment. Radio 
amateur operators all over the world will be able to receive the tele-
metry downlink utilizing RS-style CW telemetry 435.315 MHz using the
callsign RS30.

The satellite transmits a cyclic series of messages lasting for 4 
minutes including a call signal and TM-data (10 seconds); a voice 
message (1 minute); a pause (50 seconds); the first artificial 
satellite imitated signals (10 seconds); an image (1 minute); 
with a final pause (50 seconds).

Aerospace Vehicle Laboratory SCC is the primary the satellite con-
trol. A similar Satellite Control Center has been established at the 
Siberian State Aerospace University in Krasnoyarsk to allow students 
and research engineers can receive and analyze the telemetry in coop-
eration with the specialists at JSC Academician M.F. Reshetnev Infor-
mation Satellite Systems center.

1. Dutch School Contact

Delta Researchers Schools 2008, Space Expo in Noordwijk, the Nether-
lands, had an ARISS contact via telebridge station WH6PN in Hawaii on 
Friday, May 23. Twelve Dutch primary schools which participate in the 
Delta-project were represented at Space Expo. The project is a cooper-
ation of the Dutch ministry of Education, Culture and Science, the 
European Space Agency (ESA) and NASA. The schools participating in the 
project use the themes of space and space exploration to teach science 
and technology. Three children (ages 7 - 12) from each school were pre-
sent. The audio for this event was fed into the EchoLink AMSAT (101 377) 
and JK1ZRW (277 208) servers.

2. Cindy McArthur Receives Silver Snoopy Award

Last week, Teaching From Space Project Lead Cindy McArthur became the 
recipient of a Silver Snoopy award. Astronaut Barbara Morgan, KD5VNP, 
presented the award in appreciation for McArthur's work and support of 
educational activities throughout the STS-118 mission which included 
an Educational Downlinks videoconference and an ARISS contact.
