AMSAT NEWS SERVICE
ANS-222
The AMSAT News Service bulletins are a free, weekly news and infor-
mation service of AMSAT, 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 commun-
icating 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.
You can sign up for free e-mail delivery of the AMSAT News Service
Bulletins via the ANS List; to join this list see:

German Satellite Demonstrates Orbit Control on 1U CubeSat
The University of Wuerzburg Experimental Satellite 4 (UWE-4) success-
fully used its propulsion system in order to conduct orbit control.
The 1-unit (1U) CubeSat is equipped with an electric propulsion system
called NanoFEEP, developed by the Technical University in Dresden.
This marks the first time in CubeSat history that a 1U CubeSat has
changed its orbit using an onboard propulsion system. Several man-
euvers were performed within 11 days, between June 23 and July 3,
lowering the CubeSat's altitude by more than 100 meters (328 feet),
compared to an average of 21 meters (69 feet) with natural orbital
decay.
Coincidentally, on July 2, the UWE-4 team received a "conjunction data
message" from the US Air Force, indicating a potential safety threat
from a non-operational Iridium satellite, although UWE-4 was already
below the Iridium satellite at the projected time of conjunction.
Lowering the altitude of a spacecraft in low-Earth orbit (LEO) has the
negative effect of reducing its lifetime, because low-Earth-orbiting
(LEO) satellites usually burn up during re-entry. "Thus, this exper-
iment is a concept demonstration of a deorbiting maneuver shown at the
smallest class of spacecraft in LEO," the university said.
While satellites are not yet required to carry propulsion systems to
facilitate a planned deorbiting, such an obligation is under serious
discussion, due to the vastly increasing number of satellites in mega
constellations. "The experiment of UWE-4 presents a deorbiting sol-
ution for the fraction of space debris of operational, but unused,
satellites of today and for the mega constellations of tomorrow," the
university said. AMSAT notes that US regulations make the ability to
deorbit a requirement for high-Earth-orbit amateur satellites in the
future.
The first activation of the NanoFEEP thruster on UWE-4 took place in
early 2019. UWE-4 transmits telemetry on 435.600 MHz.

AMSAT CubeSat Simulator Now Transmits SSTV
Did you have fun receiving SSTV images from the ISS this past week?
A new development branch of the AMSAT CubeSat Simulator now transmits
SSTV images! See https://github.com/alanbjohnston/CubeSatSim/tree/dev
for details.
A video of FlatSat testing can be found at:

AMSAT's GOLF Program is about getting back to higher orbits, and it
all begins with GOLF-TEE – a technology demonstrator for deployable
solar panels, propulsion, and attitude control. Come along for the
ride. The journey will be worth it!

AMSAT-UK OSCAR Satellite QSO Party Ongoing
The objective of the AMSAT-UK OSCAR Satellite QSO Party is to
encourage all radio amateurs around the world to get on the air and
make contacts via satellites during northern hemisphere summer. We
would like to attract both seasoned die-hard operators as well as all
newcomers who are just getting involved.
While points are given per QSO this isn’t a contest, but we hope it
will encourage people to get on the air and enjoy the excitement of
making contacts through satellites.
The AMSAT-UK OSCAR Satellite QSO Party will be supported by an online
leaderboard which will be available from the start of the event which
runs from 00:00 GMT on 1st August until 23:59 GMT on 22nd September.
Prizes will be awarded to those from first to thirteenth place and
are open to both AMSAT-UK and non-members around the world.
● First Place £250 Amazon Voucher
● Second Place £150 Amazon Voucher
● Third Place £50 Amazon Voucher
● Fourth to Thirteenth Place One Year AMSAT-UK Membership

Hamfests, Conventions, Maker Faires, and Other Events
Want to see AMSAT in action or learn more about amateur radio in
space?
AMSAT Ambassadors provide presentations, demonstrate communicating
through amateur satellites, and host information tables at club
meetings, hamfests, conventions, maker faires, and other events.
Due to COVID-19, many hamfest and events around the United States have
been canceled or postponed. While we make every effort to ensure the
information contained below is correct, there may be some that we
missed.
QSO Today Virtual Ham Expo - August 9, 2020
