AMSAT NEWS SERVICE
ANS-337

The AMSAT News Service bulletins are a free, weekly news and infor-
mation service of AMSAT North America, The Radio Amateur Satellite
Corporation. ANS publishes news related to Amateur Radio in Space
including reports on the activities of a worldwide group of Amateur
Radio operators who share an active interest in designing, building,
launching and communicating through analog and digital Amateur Radio
satellites.

The news feed on http://www.amsat.org publishes news of Amateur
Radio in Space as soon as our volunteers can post it.

Please send any amateur satellite news or reports to:
ans-editor at amsat.org.

In this edition:

* ISS Global Testing SSTV December 5-6 Prior to MAI-75 Over Moscow
* Soyuz Launch Anomaly Results in Loss of D-Star ONE Cubesat
* AMSAT-SM Supports ARISS With New Donationn
* IARU Frequency Coordination for China's Juvenile 3U Cubesats

ISS Global Testing SSTV December 5-6 Prior to MAI-75 Over Moscow

http://ariss-sstv.blogspot.com/ published an update to the
December MAI-75 SSTV testing schedule:

**UPDATE - Nov 28**
Seems the system will be put through some extended testing from
December 5 starting around 15:00 UTC and running until 09:00 UTC
on December 6. Test images will be used during this period. This
will provide near global coverage if all works well.

The MAI-75 schedule over Moscow remains unchanged at this point.
The times correlate to a small number of passes each day in range
of Moscow.

Dec 6, 2017
Setup and power on –  13:40-14:20 UTC
Power off – 17:05-17:15 UTC

Dec 7, 2017
Power on –  13:45-13:55 UTC
Power off – 17:30-17:40 UTC

Dec 8, 2017
Power on –  14:05-14:15 UTC

Power off and stow – 17:00-17:10 UTC

Soyuz Launch Anomaly Results in Loss of D-Star ONE Cubesat

A new Russian weather observatory and the first prototype for Telesat’s 
planned
network of 100-plus broadband communications satellites in low Earth 
orbit were
among 19 spacecraft lost after a Fregat rocket stage ran into trouble 
soon after
liftoff aboard a Soyuz booster Tuesday.

The Fregat rocket pack was supposed to place the 19 satellites into four
different orbits Tuesday in a four-hour flight sequence following launch 
on a
Soyuz rocket from the Vostochny Cosmodrome, a new spaceport in the Amur 
region
of Russia’s Far East.

A report published by Russia’s Interfax news agency Tuesday quoted a Russian
space industry source who attributed the apparent failure to human 
error. The
source said a mistake uploaded to the Fregat’s flight computer caused 
the upper
stage to be in the wrong orientation for the main engine’s first burn, 
which was
scheduled to last 77 seconds to reach a temporary parking orbit a few 
hundred
miles above Earth.

Billed as the first German commercial CubeSat, the D-Star One spacecraft had
four communications modules on-board, two of which were to be used by the
amateur radio community. Developed by German Orbital Systems in Berlin in
cooperation with the Czech company iSky Technology, officials hope to build
follow-on satellites to construct a low Earth orbit communications network.

AMSAT-SM Supports ARISS With New Donation

AMSAT-SM is proud to announce a donation to ARISS (via AMSAT-NA) of
$285. We hope that this small donation will help ARISS further work
with amateur radio from ISS.

AMSAT-SM is the Swedish section of AMSAT with approximately 220 members. 
One of
their objectives is to inform Swedish hams about the fun with amateur
satellites! Not many SM hams are active via satellite at the moment. 
With the
help from our Swedish webpage and HF-net we hope that more Swedish hams 
should
be using amateur satellites. The AMSAT-SM annual meeting is held every 
spring.
Some weeks on Sundays we have a HF-net on 80 meters with lots of news about
satellites and space.

IARU Frequency Coordination for China's Juvenile 3U Cubesats

The IARU Amateur Satellite Frequency Coordination Status pages,
hosted by AMSAT-UK as a service to the world wide Amateur Satel-
lite Community, report on an updated coordination for the Juvenile
project from China.

Juvenile is a 3U CubeSat project led by China Soong Ching Ling
Youth Science and Culture Center for school education and amateur
radio.

The amateur radio station onboard will provide telecommand, tele-
metry and FM repeater functions:

1. A VHF uplink and UHF downlink data control board with loop
    back function, which can act as an FM repeater.

2. A VHF uplink and UHF downlink 9k6 BPSK data control back up
    board, with a trigger to take a photo from a camera, and
    transmit SSTV image through NBFM modulation.

3. A 2.4 GHz band with 2 MHZ bandwidth multiple frequency up
    and down link communication experiment.

Planning a launch from Jiuquan Space Center into a 500km Sun
Synchronous Orbit.

The IARU reports a November 30 revised coordination has been
provided.

Frequency coordination for Juvenile 1B, 1D and 1F
Uplink     435.290 MHz FM
Downlink   145.840 MHz FM
Telemetry  145.930 MHz 9K6 BPSK

Frequency coordination for Juvenile 1A, 1C, 1E and 1G
Uplink     145.965 MHz FM
Downlink   436.250 MHz FM
Telemetry  437.475 MHz 9K6 BPSK
