UKube-1 CubeSat Completes Mission

From AMSAT News Service:

UKube-1, the UK Space Agency’s first national spacecraft, has now completed
its nominal mission following over 14 months of operations. Discussion is
underway with AMSAT-UK about the possibility of taking over UKube-1 operations
to continue its educational and outreach activities.

Launched in July 2014, UKube-1 is a technology demonstration mission with a
broad set of objectives aimed at attracting and training future generations of
engineers, encouraging collaboration across sectors and institutions, fast
tracking space technology development and engaging with students.

As a 3 unit CubeSat (30x30x10cm), flying 4 main payloads, with all the key
subsystems of much larger satellites, UKube-1 remains one of the most advanced
CubeSats ever built. Despite some technical challenges in orbit, the mission
has achieved a range of milestones including:

• delivery into the correct planned orbit (around 650km, sun-synchronous)
• successful deployment of solar panels and antenna
• good battery health
• slow spin rate measured
• uplink and downlink capabilities checked, including Large Data Transfer,
downlink at 3 speeds, and redundant communications mode
• all core payloads commissioned and data collected for each
• on-board camera technology successfully tested
• data downlinked from multiple ground stations across the globe

UKube-1 has also helped maintain the UK’s leading position in the CubeSat
sector. Participation in the mission placed Clyde Space in an excellent
position to capitalize on the fast growing global nanosatellite market. The
company has experienced 100% year on year growth, both in turnover and
employees, as a direct result from involvement in UKube-1, and is firmly
established as a global leader.

Mark McCrum, Bright Ascension Ltd, said:
“UKube-1 provided us with an invaluable opportunity to gain flight heritage
for our software technology and to get deeply involved in the operation of a
complex CubeSat mission. It gave a huge boost to our credibility as a space
software provider and has been instrumental in winning further work.”

Craig Clark, CEO Clyde Space Ltd, said:
“UKube-1 represents a pivotal achievement in the development and growth of
Clyde Space. The project moved the company from being a spacecraft subsystems
supplier to providing full missions for our customers. To give some context to
the extent that Ukube-1 has had to our business, Clyde Space has more than
quadrupled in size in the last 3 years and there are currently over 60 CubeSats
planned through production here in Glasgow over the next 18 months. The return
on investment for Ukube-1 in terms of jobs and export sales for the UK has been
outstanding and is a great example of industry and the UK Space Agency working
together to put the UK at the forefront of global space technology.”

Professor Andrew Holland, Open University, added:
“Involvement in the UKube-1 mission, though our C3D instrument, has had a
positive effect on our research and technology program within the Space
Instrumentation Group at the Open University, as well as a positive effect on
our technology partners in the project; XCAM Ltd and e2v Ltd. The project has
helped the OU to build a new strand of instrument development within the group,
raised awareness of the CubeSat platform as a potential vehicle to accelerate
the development of scientific space instrumentation, and has provided early in-
orbit-demonstration of technologies. The mission introduced us to new academic
and industrial collaborators operating in the space sector and supported the
career development of the young engineers and scientists working on the
project.”

STFC’s RAL Space provided the Ground Station for the mission at Chilbolton
Observatory in Hampshire UK, and UKube-1 operations were commanded from there.

Mission Manager Dr Helen Walker said:
“It has been a very exciting time, made possible only with the great support
from all the teams involved.”

Although the Agency-supported mission phase has ended, discussion is underway
with AMSAT-UK about the possibility of taking over UKube-1 operations to
continue its educational and outreach activities until the satellite orbit
naturally degrades.

UKube-1 carries a set of AMSAT-UK FUNcube boards which provide an educational
beacon for use by schools and a linear transponder for amateur radio
communications.

UKube-1 nominal frequencies:
• 145.840 MHz Telemetry downlink
• 145.915 MHz FUNcube subsystem beacon
• 400 mW inverting SSB/CW linear transponder
– 435.080-435.060 MHz Uplink
– 145.930-145.950 MHz Downlink

Video of Fox-1A Deployment from P-POD

A video showing the deployment of Fox-1A from the P-POD aboard the Centaur stage of the NROL-55 launch has been made available.

As each P-POD deployed, the deployment was recorded on video.  The video is only about 3 seconds long, so it goes quickly.  Jerry Buxton, N0JY, edited the video to add a 1/8 speed “slow motion” of the deployment which immediately follows the original in this YouTube video.

Fox-1A was in the bottom position of the P-POD, with BisonSat in the middle and then ARC1 at the top.  You can catch a glimpse of the -Z and -Y faces of the Fox-1A satellite as it quickly disappears into the darkness with BisonSat and ARC1.

New Release of FoxTelem

From the AMSAT Bulletin Board Mailing List:

I wanted to announce the release of FoxTelem Version 1.01. If possible,
everyone should upgrade to this new version. In addition to some new functionality it fixes some bugs and issue that mean more data will be uploaded to the server.

This is a patch release. If you already have 1.00 installed then download
the file FoxTelem_1.01_patch.zip

You can download it from:
http://amsat.us/FoxTelem/windows
http://amsat.us/FoxTelem/mac
http://amsat.us/FoxTelem/linux

Only two files have changed (plus the manual). Copy these files into your
install directory
– FoxTelem.jar
– spacecraft/FOX1A_radtelemetry2.csv

You can also download the whole install file and install it in a new
directory. You can use the
settings menu to continue using your existing log files. Ask if you need
assistance.

Lots has changed in this release and many bugs have been fixed. Please
report any issues
that you see.

Release notes:
* Allow the user to view and set the “track” attribute for each spacecraft
(and other parameters)
* Better doppler tracking in IQ mode and more stable estimate of the
received frequency
* Better Find Signal algorithm with tuning paramaters for experts
* Read Time Zero from the server for each reset and use to plot graphs in
UTC
* Set the default fcd frequency to 145930 so that Fox-1A, Fox-1Cliff and
Fox-1D will be in the passband
* Allow the gain to be set on the FCD (rather than hard coded)
* Do not change the FCD LNA or Mixer Gain. Leave unchanged.
* Do not open the FCD unless the start button is pressed
* Fixed a bug where the last 2 bytes of the radiation telemetry were not
decoded correctly
* Allow Vanderbilt radiation experiment to be graphed
* Allow user to select UDP or TCP for upload to the server (but use UDP
for now please)
* Shorten the period between passes so that graphs look continuous
* Ignore duplicate high speed radiation frames – needed for processing
data from the server
* Allow graphs to be hidden so that average or derivative is easier to see
* Notify the user when a new release is available
* Cleaned up the FFT trace with some averaging
* If showRawValues is checked then save CSV files as raw values
* Several updates to the manual

4U1UN as 4U70UN on satellite October 24-25

4u1unWord has been received, that, in celebration of the UN’s 70th
anniversary, 4U1UN will be activated as 4U70UN on Saturday 24 and Sunday
25 October. The operation by the UN ARC will be from the ground-level
garden area within the UNHQ complex in New York City and will be limited
to daylight hours. Satellite operation is included in the plans, but
time and equipment limitations will exist. Blockage from high rise
buildings toward the West is expected. Best passes will be to the East
of FN30as and North/South overhead. Possible satellites in view may be
AO-73, FO-29, AO-85, AO-7, SO-50, XW-2E and XW-2F. Note that 4U1UN is a
separate DXCC entity. See QRZ.COM for QSL info.
