On the AMSAT Bulletin Board (AMSAT-BB) Nico Janssen PA0DLO has posted a summary of the presently known IDs for the satellites that were launched on the Yasny Dnepr on November 21.

Further Doppler measurements show that TshepisoSat (aka ZACube-1) is object 39417 (2013-066B) and AMSAT-OSCAR-73 (aka FUNCube 1) is object 39444 (2013-066AE). Therefore HiNCube must be object 39445 (2013-066AF).

It is not easy to get a good Doppler curve with many CubeSats because of the limited transmissions and because of the frequency drift of their beacon transmitters.

These object IDs from the Dnepr launch seem to be correct, although some still need to be confirmed (tbc):

39416 2013-066A  Aprizesat 7
39417 2013-066B  TshepisoSat
39418 2013-066C  Skysat 1
39419 2013-066D  Dubaisat 2
39421 2013-066F  Unisat 5
39422 2013-066G  STSat 3
39423 2013-066H  WNISat 1
39425 2013-066K  Aprizesat 8
39427 2013-066M  Triton 1
39428 2013-066N  Delfi-n3Xt
39429 2013-066P  Dove 3
39430 2013-066Q  GomX 1
39431 2013-066R  BRITE-PL
39433 2013-066T  HumSat D
39436 2013-066W  Eagle 2 ($50Sat) (tbc)
39438 2013-066Y  Velox PII (tbc)
39439 2013-066Z  First-MOVE (tbc)
39440 2013-066AA CubeBug 2 (tbc)
39444 2013-066AE AMSAT-OSCAR 73
39445 2013-066AF HiNCube
39446 2013-066AG UWE 3 (tbc)

Young radio hams at Fontana school anticipate ISS link

International Space Station ISS with shuttle Endeavour 2011-05-23

Ten year-old radio amateurs Maribel Laguna KK6IGY and Laisha Vergara KK6HZH hope to link up with the International Space Station next year.

The San Bernardino Sun newspaper reports both are students at the Dorothy Grant Elementary School in Fontana. The school has a popular amateur radio club with nearly 50 members which was founded by teacher Beverly Matheson KJ6RSX.

Beverly said originally she looked at the club as a platform to get students interested in cultures in other lands.

Using the club’s high frequency radio and portable antenna, students set up outside the classroom and take down after their weekly meetings — students have made contact with amateur radio operators such diverse places as Hungary, Maldovia, Japan and the Falkland Islands.

But now Beverly said she wants to personally, and with her students, delve more into science with ham radio as a platform for a STEM program at the school.

Along those lines, next year — before the end of school — the Grant Elementary School Amateur Radio Club will be talking with astronauts aboard the International Space Station.

TshepisoSat was built at the French South African Institute of Technology (F’SATI), at the Cape Peninsula University of Technology and launched on a Dnepr from Dombarovsky near Yasny on November 21, 2013.

The CPUT-F’SATI blog says:

Earlier this week a quick checkout of the payload board was done. The sub-system board was powered on and a few telemetry values were requested with all response values indicating good health. The board was successfully switched off again.

On the morning of December 14 the satellite was again commanded to switch on the payload board and a sequence of commands were sent to capture an image and store it in the on-board storage. During the following two passes the image was successfully downloaded using the CPUT/F’SATI built VHF/UHF radio transceiver in its 9k6 bps G3RUH/GMSK mode.

In the image the sun can be seen along with lens flare caused by the camera being pointed towards the sun. The black dot in the bottom right is most likely caused by overload of camera’s CMOS sensor by the sun. The spacecraft is not stabilized in three axis, so capturing images is a best effort affair (imaging is not the main focus of the mission). We can hopefully capture an image showing the earth in the upcoming days.

Original known as ZACube-1, the satellite has been named TshepisoSat, after a competition held for Grade 9 learners. Tshepiso is the seSotho word meaning promise.

The launch was the culmination of five years’ work after the first proposal to build a small satellite as part of the engineering curriculum was put forward by Professor Robert van Zyl in February 2008. Co-operation of the French Government made possible the forming of F’SATI and the French Ambassador in South Africa, Elizabeth Barbier, during a video address, promised continued support by France for the program.

The satellite also includes a small camera which will be used to monitor the releases of the 20 metre beacon antenna. The beacon will operate on 14099 kHz and will be used to characterize the Superdarn antennas at the Antarctic which are used to study the ionosphere. The UHF beacon operates on 437.345 MHz.

First Novel inspired by Cubesats and Personal Spacecraft

A Pyramid of Tiny Skulls - Andy Thomas G0SFJThe first novel to find inspiration from Cubesats and the new wave of personal spacecraft – such as the Sprites – has been published and is available from Amazon and Createspace.

In ‘A Pyramid of Tiny Skulls’, the story is this:

“On the edge of the city lies the neglected Scheme, a City Fund zone bounded by the Lake and the Pyramid.

Jack Malik, entrepreneur and nightclub operator, carries a letter from murdered dancer Alina home to Russian enclave Kaliningrad, and agrees to collect a secret parcel from Shanghai.

What he brings will attract the City Leader’s attention, and echo through the Cosmos.”

The novel is dedicated to whom Andy Thomas G0SFJ describes as “the visionaries of CubeSats and personal spacecraft”.

The Kindle page on the Amazon website allows you to read a sample of the book, see

KySat-2 Ham Radio Software Update

Archive image of KySat-1

Archive image of KySat-1

Jason Rexroat KK4AJE of the University of Kentucky KySat-2 team brings news of the latest version of the amateur radio ground station telemetry decoder software.

We really appreciate everyone using our ground station software to decode KySat-2 packets!  We are continuing to take suggestions and made several more bug fixes, and the third version of this software is now available for download!

Link: http://ssl.engineering.uky.edu/amateur-radio-operators/
KySat-2 Info: http://kentuckyspace.com/ or http://kysat2.engr.uky.edu/

Our changelog is included in the download, and also copied below.  Again, we appreciate all who have helped us gather telemetry from our satellite, and please continue to do so!  Email us with any bugs or suggestions for improvements and we’ll be sure to work on it!

Changelog:

– “Share” button to automatically email us our log files, along with counters showing how many beacons you’ve shared
– Custom COM port selection in case your created COM port doesn’t show up in our list
– Drag and dockable tabs
– Packaged into single executable file

These changes will enable further customization on your part, and the automatic sharing will put the data into a format our automated scripts can handle to generate our running telemetry tables. I know that the ping functionality is still disabled, but we are pushing through further subsystem checkout that will allow us to enable this and other functionality for you!
