All,
Here?s a map of US military satellites, aka FLTSAT (I think). These are
geostationary and above the equator.

What are you trying to do ?
Is it a rotator ?
Can we fool it with dummy data

AMSAT NEWS SERVICE
ANS-323
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:

DATE November 19, 2017
To All RADIO AMATEURS
BID: $ANS-323.01
RadFxSat (Fox-1B) Launched, Designated AMSAT-OSCAR 91 (AO-91)
The Delta II rocket carrying RadFxSat (Fox-1B) launched at 09:47:36
UTC on November 18, 2017 from Vandenberg Air Force Base, California.
Following a picture-perfect launch, RadFxSat was deployed at 11:09
UTC. Then the wait began. At 12:12 UTC, the AMSAT Engineering team,
watching ZR6AIC's WebSDR waterfall, saw the characteristic "Fox Tail"
of the Fox-1 series FM transmitter, confirming that the satellite was
alive and transmitting over South Africa. Shortly after 12:34 UTC, the
first telemetry was received and uploaded to AMSAT servers by Maurizio
Balducci, IV3RYQ, in Cervignano del Friuli, Italy. Initial telemetry
confirmed that the satellite was healthy.
After confirmation of signal reception, OSCAR Number Administrator
Bill Tynan, W3XO, sent an email to the AMSAT Board of Directors
designating the satellite AMSAT-OSCAR 91 (AO-91). Bill's email stated:
"RadFxSat (Fox-1B) was launched successfully at 09:47 UTC today
November 18, 2017 from Vandenberg Air Force Base in California and has
been received by several amateur stations.
RadFxSat (Fox-1B), a 1U CubeSat, is a joint mission of AMSAT and the
Institute for Space and Defense Electronics at Vanderbilt University.
The Vanderbilt package is intended to measure the effects of radiation
on electronic components, including demonstration of an on-orbit
platform for space qualification of components as well as to validate
and improve computer models for predicting radiation tolerance
of semiconductors.
AMSAT constructed the remainder of the satellite including the
spaceframe, on-board computer and power system. The amateur radio
package is similar to that currently on orbit on AO-85 with an uplink
on 435.250 MHz (67.0 Hz CTCSS) and a downlink on 145.960 MHz.
Experiment telemetry will be downlinked via the DUV subaudible
telemetry stream, which can be decoded using the FoxTelem software.
RadFxSat (Fox-1B) was sent aloft as a secondary payload on the United
Launch Alliance (ULA) Delta II rocket that transported the JPSS-1
satellite to orbit. RadFxSat (Fox-1B) is one of five CubeSats making
up this NASA Educational Launch of Nanosatellites
(ELaNa) XIV mission, riding as secondary payloads aboard the JPSS-1
mission.
Since RadFxSat (Fox-1B) has met all of the qualifications necessary to
receive an OSCAR number, I, by the authority vested in me by the AMSAT
President, do hereby confer on this satellite the designation
AMSAT-OSCAR 91 or AO-91. I join amateur radio operators in the U.S.
and around the world in wishing AO-91 a long and successful life in
both its amateur and scientific missions.
I, along with the rest of the amateur community, congratulate all of
the volunteers who worked so diligently to construct, test and prepare
for launch the newest amateur radio satellite.
William A. (Bill) Tynan, W3XO
AMSAT-NA OSCAR Number Administrator"
AMSAT Engineering reminds stations that the satellite will not be
available for general use until the on-orbit checkouts are complete.
Please continue to submit telemetry to assist the Engineering team in
completing the commissioning process.

ESA Announcement for CubeSat Team Concurrent Engineering Workshop
Dreaming of flying a satellite into space but not sure how? Wonder
no more! The ESA Education Office and ESA's Systems and Concurrent
Engineering Section have the perfect workshop for you. We are currently
looking for university students who would like to participate in ESA
Academy's first? Concurrent Engineering Workshop dedicated to CubeSats.
The 4-day workshop will be organised between 16 and 19 January 2018 at
the Training and Learning Centre in ESEC, Belgium.
In concurrent design, all stages of a satellite design take place simul-
taneously, through the direct collaboration of engineers and scientists
from different disciplines in a dedicated and specially equipped facility.
The "CubeSats Concurrent Engineering Workshop" will introduce student
teams to the concurrent design of a CubeSat mission. The workshop can help
to better prepare those universities that are planning to embark on a Cube-
Sat project or are at the early stages of one. Teams wishing to participate
do not need to be at an advanced stage in their CubeSat project. They can
be at a conceptual and/or preliminary phase of their CubeSat design.
The deadline for applications is 4 December 2017, 23:59 CET.
Application requirements, program overview, and more information can be
found on-line at: http://tinyurl.com/ANS-316-ESA-Workshop

Australian Amateurs do first HamTV Telebridge outside of Europe
Led by Shane, VK4KHZ in Queensland who handled the audio on 2m. and
video for a
telebridge contact between the ISS and 3 Italian schools? on 11 Nov.? Four
stations across Australia joined together to "chain" the live video
coming down
from the ISS on 2.4 Ghz.
As the ISS approached Australia from the west Martin VK6MJ in West
Australia was
the first to receive the video signal down from Paolo, IZ0JPA and held the
signal till Joe VK5EI in Adelaide picked it up then onto Tony VK5ZAI in
Kingston
SE South Australia finally as the ISS headed N-E over Queensland Shane
picked up
the video signal in Glenden while he was handling the audio for the linkup.
The video from the 4 Australian hams was streamed live to the BATC site
in GB.
where it was patched together to form one long video transmission so the
public
could watch as Paolo answered the Italian students questions.
The URL for the British Amateur Radio Club is: https://ariss.batc.tv/hamtv/

December 20 Launch for HA-1 CubeSat with FM transponder and SSTV
The IARU has announced frequency coordination has been completed for
HA-1, a 2U CubeSat developed by the Teenagers Amateur Radio Center of
Activity in Huaian, China. HA-1 is planned for launch on December 20.
HA-1 will be mainly used for teenagers in Huaian to carry out activities
related with amateur radio and aerospace science education. The cubesat
is equipped with amateur radio repeater and SSTV(Slow Scan Television)
component, which is to validate still image transmission in narrowband
voice channel.
There is an SSTV beacon, which puts Date/Time/Location information/temp-
erature etc on a SSTV picture. Amateurs worldwide can also use HA-1 to
test SSTV via the cubesat.
Uplink:??? 145.930 MHz FM
Downlink:? 436.950 MHz FM
Telemetry: 437.350 MHz 9k6 BPSK

HamSCI Announces Workshop - Posts Survey
HamSCI - the Amateur Radio citizen science initiative - has announced a
2-day workshop February 23-24 at New Jersey Institute of Technology (NJIT)
in Newark. HamSCI's Nathaniel Frissell, W2NAF, has posted a survey to
gauge interest and potential attendance.
"We are inviting all hams and scientists interested in ham radio science,"
Frissell said. "This aim of this workshop is to foster collaborations
between the ham radio and the space science and space weather research
communities through presentations, discussions, and demonstrations. This
year's meeting will focus on solar eclipse analysis, ham radio data sources
and databases, and the development of a 'personal space weather station.'"

Andrew,
This is a great way for somebody to get a satgate up an running quickly.
Thanks! One suggestion I would make is to use the direwolf "SATGATE"
command with an argument of 15s (IE: "SATGATE 15"). This will help
eliminating "black holes" at your QTH with your own packets.

Hi JP,
May be GSP is an alternative to have a geostationary device over your
