6th European CubeSat Symposium

Swiss Space Systems S3

Swiss Space Systems S3

The 6th European CubeSat Symposium will take place from October 14-16, 2014 at Estavayer-le-Lac in Switzerland.

The Symposium has attracted more than 100 abstracts submitted from 31 different countries. Von Karman Institute and Swiss Space Systems are proud to support the CubeSat community by coorganising this leading CubeSat event in Europe, for the first time in Switzerland.

Von Karman Institute continues to act as the coordinator of the World’s most ambitious CubeSat Project QB50, whereas Swiss Space Systems is designing an innovative launcher specifically for small satellites to bring the launch costs to 25% of today’s market value.

The symposium abstracts are available at

Silverstone B-64 balloon still flying

The B-64 balloon launched at 06:51 GMT on July 12, 2014 from Silverstone is still in the air flying at just over 12,000 metres and transmitting on 434.500 MHz Contestia 64/1000 and also APRS.

On Saturday, October 3 Phil Heron MI0VIM reported decoding data while it was over the North Atlantic ocean, coming up to the 6th time it would pass the United Kingdom on it’s continuing journeys around the world.

B-64 was built by radio amateur Leo Bodnar M0XER, he made both the plastic foil envelope and the solar powered transmitter payload which weighs just 11 grams.

Leo has utilised some clever techniques storing positions when the balloon is out of radio contact then later transmitting a log file of previous locations in the comments field of the APRS packet. This enables a fairly complete path to be built up. B-64 only stores 5 days worth of data, where you get a straight line on the track it has been out of radio contact.

4M lunar ham radio payload shipped

4M payload under test

4M payload under test

Ghislain Ruy LX2RG reports the 4M Lunar flyby amateur radio payload was shipped on Thursday, October 2 and he departs for the Xichang Satellite Launch Center on Sunday, October 5.

He says the lifetime of 4M is quite an unknown: it may be as short as 100 hours (so at least to the Moon) and could extend for some weeks if the attitude is favorable.

It is now known that the spacecraft will not re-enter the Earth atmosphere after the flyby but instead enter a wonderful orbit. You will find information animations and some JT65B test files at

https://cloud.luxspace.lu/public.php?service=files&t=33c4a21c09ba3736a55fc09896e463f6

The launch will be transmitted by CNTV/CCTV: http://www.cntv.cn/ or http://english.cntv.cn/ or http://english.cntv.cn/live/p2p/index.shtml

LX2RG says the team are setting up their ground station, and are especially looking for southern hemisphere stations: ZS, VK and ZL, Southern America continent mainly, as they will be placed first hand for the early hours.

Launched is planned in a narrow window at 17:59:xx UTC on October 23 and flyby is to occur nominally on October 28 at 00:33 UTC.

4M is planned to start transmissions at 19:17 UTC, possibly with 10 minutes additional delay.

K1JT has developed a special version of WSJT. In addition of all the features of the standard version, it includes also the display and logging of the dT to three decimal places and the logging of the manual offset that can be entered in JT65B modes. This version should be used by all who wants to participate to the ‘Multilateration’ experiment.

The participant to this experiment should also make sure that the clock of their PC stays synchronized to the UTC time. Desired accuracy should be within 1ms and within 10ms at the very least. Use of NTP synchronizing software is a must.

The special version can be downloaded with the following links:

https://cloud.luxspace.lu/public.php?service=files&t=2720825f74104b31ebd699dcc0fd6268

The LuxSpace ground station comprises 2 x 8 element crossed Yagis from Joachims antenna (with an improved design to lower the back lobe), a SSB.de LNA and Yaesu antenna rotators.

Best regards.

UK schools contact with International Space Station

Astronaut Alexander Gerst KF5ONO

Astronaut Alexander Gerst KF5ONO

On Wednesday, October 8 at 10:08:49 UT there will be an ARISS contact between astronaut Alexander Gerst KF5ONO on the International Space Station (ISS) and students at the Winter Gardens Primary School, Canvey, Essex and Pilton Bluecoat School, Barnstaple, Devon.

The ISS will be over the USA at the time and they will be making use of an amateur radio Telebridge Ground Station in California, W6SRJ, to actually make the link to the Space Station.

The poster parodies the popular The Hitchhiker’s Guide to the Galaxy by Douglas Adams and is without doubt the best ISS crew poster yet released.

USA’s Terry Virts and Russia’s Anton Shkaplerov portray the two-headed Zaphod Beeblebrox, Russia’s Alexander Samokutyaev is Humma Kavula, USA’s Butch Wilmore is Arthur Dent, Russia’s Elena Serova is Ford Prefect with Italy’s Samantha Cristoforetti as Trillian. NASA’s Robonaut 2 guest-stars as Marvin the Paranoid Android.

Samantha should launch from Baikonur in Kazakhstan on November 23, 2014 at 2059 UT (3:59pm EST) also flying with her in the Soyuz will be Anton Shkaplerov and Terry Virts. She is expected to return to Earth in May 2015.

Help needed to track 144.390 MHz APRS Balloons

James Cutler KF6RFX and Benjamin Longmier KF5KMP - University of Michigan

James Cutler KF6RFX and Benjamin Longmier KF5KMP University of Michigan

Benjamin Longmier KF5KMP and his team are looking for stations in the Azores and Portugal to help track their balloons.

On the UK High Altitude Society (UKHAS) group he writes:

My team (Project Aether) launched a balloon recently that did a lap around the Midwest in the US, headed East past Nova Scotia and is still floating strong. We don’t have any contacts in the Azores or Portugal, and are requesting help in contacting some of these folks that might be able to decode our APRS packets.

We also have two more experimental balloons that will be heading into the Atlantic within ~24hrs.
