Virgin
Orbit Plans Flight Test of LauncherOne Rocket in February
Virgin Orbit,
AMSAT's launch for RadFxSat-2/Fox-1E, has announced
they expect to have their
first test launch of LauncherOne, their
airborne-launched rocket, sometime in
the second half of February.
The LauncherOne rocket is carried on the VO 747
Cosmic Girl aircraft.
If this first test flight is successful
RadFxSat-2/Fox-1E is planned
for launch on the second flight of LauncherOne
during 1Q 2020 on the
ELaNa XX
mission.

AMSAT
at Cowtown Hamfest - Ft. Worth - January 17-18
AMSAT will be represented
at the 2020 Cowtown Hamfest in Fort Worth,
TX on January 17 and 18 with a
table, demos and presentations. If you
live in the North Texas area, this is
a great event, well attended
and lots of vendors. Please put it on your
calendar. Info posted at
http://www.cowtownhamfest.com/AMSAT
Ambassador Tom Schuessler, N5HYP, says he has openings to staff
the table, do
the demos and assist with the presentations.
The Cowtown amateur Radio
Club was a home for our dearly beloved and
SK, Keith Pugh, W5IU. The
organizers offered AMSAT a no charge table
space in the market area so a big
thank you to them is in order.
Tom hopes you can plan to be a part of
this fine event. If you can
assist in any way for AMSAT, please drop Tom an
email at:

CAMSAT
Says CAS-6 Activation for Amateur Use has been Delayed
01/07/2020 - via
ARRL
Chinese Amateur Satellite Group (CAMSAT) CEO Alan Kung, BA1DU,
tells
ARRL that some problems with the precise attitude determination
of
the newly launched CAS-6 amateur radio satellite have delayed
deploy-
ment of the antennas. The satellite was to have been put into
service
within 3 days.
“If the V/UHF antennas are deployed now,
additional torque may affect
determination of the satellite attitude,” Kung
said. “Engineers need
to modify and upload the software, which will take some
time.” He
said that taking into consideration the upcoming long Chinese
New
Year holiday, the test work is planned to be completed sometime
in
late February or early March. At that time, VHF/UHF antennas will
be
deployed, and the amateur radio payload will be available for use.
Kung
points out that the satellite’s CW beacon has been turned on,
although the
antenna has not yet been deployed. “If you have a ‘big
ear,’ you may be able
to receive weak signal leaked from an undeploy-
ed antenna on 145.910 MHz,”
he said. “A polyimide cover on the anten-
na chassis can help to leak some RF
signal.”
CAS-6 launched successfully on December 20, piggybacked on a
TIANQIN-1
technology test satellite. The microsatellite will be known
as
CAS-6/TIANQIN-1, and the call sign is BJ1SO. The primary launch
pay-
load was the China-Brazil Earth Resources Satellite,
CBERS-4A.
CAS-6 is in a sun-synchronous orbit with an apogee of 390
miles. It
carries a U/V linear transponder, with a downlink of 145.925, 20
kHz
passband (inverted) and an uplink of 435.28 MHz. The CW
telemetry
beacon is on 145.910 MHz, while 4k9 baud GMSK telemetry will be
trans-
mitted on 145.890 MHz.

Telemetry
Dashboard Available for SMOG-P and ATL PocketQubes
The SMOG-P and ATL
PocketQube team at the Budapest University of Tech-
nology and Economics has
released additional information about their
satellites recently launched by
RocketLab from New Zealand.
SMOG-P digital downlink: 437.150
MHz
ATL digital downlink: 437.175 MHz
More information on both
satellites is posted at:
http://gnd.bme.huSMOG-P (MO-105) is a 1p
PocketQube (5x5x5 cm, 250 grams), a fully re-
dundant tiny satellite with an
actual scientific payload: a flying
spectrum analyzer. It measures the
scattered RF energy over the UHF
band (specifically, in the digital
terrestrial TV band) that can be
detected in space.
ATL-1 (MO-106) is
a larger 2p PocketQube featuring the same spectrum
analyzer
experiment.
Both satellites transmit almost identical telemetry data. In
addition
to basic CW telemetry carrying callsign, battery voltage and
tempera-
ture, there is digital telemetry with variable data rate and
coding
scheme. Most frequently, modulation is 1250 or 5000 bps GMSK. The
data
is encoded either by the well-known "AO-40" FEC, or a shorter,
pro-
prietary variant of it, but they can also use a more powerful,
state-
of-art repeat-accumulate (RA) coding scheme.
Some practical
information about receiving the telemetry:
A GUI telemetry receiver is
available for Windows and Linux (soon for
OS X as well), and a command line
receiver can also be used (Linux
only). Both can be downloaded from:
https://gnd.bme.hu:8080/indexThe
programs are able to submit the received packets to the central
telemetry
data base. This requires a quick registration, the login
credentials can be
used with either of the decoders. There are some
issues with the GUI software
that hopefully will be resolved within
a few days. These decoders assume
either a USB receiver connected
through the sound card or an rtl-sdr
receiver.
Thanks to Daniel Estevez, EA4GPZ, a high quality, full decoder
and
packet uploader is also available for GNU Radio 3.8 within the
out-
of-tree module gr-satellites. For uploading to the received
packets,
it uses the same login as the "official" programs do:
https://github.com/daniestevez/gr-satellites/tree/maint-3.8This
decoder can unleash the full potential of the RA FEC. You'll
need to put an
FM demodulator in front of the flowgraph.
The team is looking forward to
seeing many submissions on the "Leader-
board" from around the world:
https://gnd.bme.hu:8080/leaderboardHaving
many receiving stations around the globe could greatly improve
the global
picture the spectrum analyzer payload can offer.

MIT
Radio Society W1MX January Lecture Series on “Everything Radio”
The
Massachusetts Institute of Technology Radio Society (W1MX) and
the Department
of Electrical Engineering and Computer Science are
hosting a lecture series
in January that may answer some of your
questions about such topics as radar
techniques, interferometry,
imaging, and radio astronomy, to antenna design
and modern chip-
scale RF devices. No prior experience with radio is
necessary, and
all are welcome.
All lectures will take place in the
Green Building — MIT’s tallest
academic building. Sessions will be live
streamed and archived for
later viewing. The lectures have already kicked off
on January 10
with “The Next Generation of Weather Radar.” Other topics
include
“Lightning Interferometry” (January 13); “Radio Noises from the
Sky”
(January 15); “EDGES: Measuring the Early Universe” (January
22);
“Antennas” (January 24), and “Chip-Scale THz Circuits and
Sensors”
(January 29). Lectures begin at 5 PM ET and conclude at 7
PM.

AMSAT-DL
Announces a New QO-100 DownConverter V3d
The first version of the
AMSAT-DL down converter was built in early
2019, enabling many stations to
become active on QO-100 for the first
time. Since then, a lot of operating
experience and new insights have
been gained, which have flowed into the new
board V3d.
The AMSAT-DL DownConverter V3d is a completely new
development. It
offers important functions for all QO-100 stations, no matter
if you
work with VHF/UHF, HF transceiver, or an SDR. This new board can
be
used as a central frequency converter assembly for your QO-100
sta-
tion providing stable clocks for all components meaning that
addi-
tional external GPS modules are not required.
The specification
for the AMSAT-DL DownConverter V3d includes:
+ Centralized clock
generation with GPS or OCXO
+ Reference clock for the PLL in the LNB
+
Reference clock for a transmit mixer
+ Reference clock for an SDR
+
Short-circuit proof LNB phantom power
+ Connection for a dual LNB (for
simultaneous NB and WB reception)
+ Downward mixing of the NB transponder
into an amateur band
(UHF/VHF or HF)
+ OLED display for displaying the
operating status and the station
coordinates
The full specification
and list of features is posted at:
