Words are often inadequate to express my joy for your help.
For your invaluable help, great support and patience, I say thank you.
Christmas is the season for peace, joy and fellowship with family and friends.
So I wish you and your families a Very Merry Christmas and a Prosperous New Year.
In German Merry Christmas is ‘Frohe Weihnachten’ ;-)

ITU World Radiocommunication Conference Finds Amateur Bands Unsuitable for Non-Amateur Satellites
The World Radiocommunication Conference (WRC) held in Geneva during November 2015 has recommended an agenda for the next WRC, to be held in 2019, to the Council of the International Telecommunication Union (ITU). One of the agenda items is of particular interest to the small-satellite community.
Agenda item 1.7 for WRC-19 reads: “to study the spectrum needs for telemetry, tracking and command in the space operation service for non-GSO satellites with short duration missions, to assess the suitability of existing allocations to the space operation service and, if necessary, to consider new allocations, in accordance with Resolution COM6/19 (WRC-15).”
Resolution COM6/19, which eventually will be given a new number, specifies the frequency ranges that may be considered for possible new allocations.
They are 150.05-174 MHz and 400.15-420 MHz.
One of the factors that the conference considered in deciding on these particular frequency ranges was “that some non-amateur satellites have used frequencies for telemetry, tracking and command in the frequency bands
144-146 MHz and 435-438 MHz which are allocated to the amateur-satellite service, and that such use is not in accordance with Nos. 1.56 and 1.57.”
Those two provisions of the ITU Radio Regulations define the amateur and amateur-satellite services respectively.
The International Amateur Radio Union welcomed the exclusion from consideration of all existing frequency allocations to the amateur and amateur-satellite services. IARU President Tim Ellam, VE6SH, observed: “This is an excellent result for the amateur services and clearly shows that non-amateur satellite constructors need to consider spectrum other than the very limited and congested segments that are available for amateur satellites at 144 MHz and 435 MHz.”
Another year of success and happiness has passed.
Thanks for all your continuous support and cooperation throughout the year!! I couldn’t have done it without you.
With every new year, comes greater challenges and obstacles in life. I wish you courage, hope and
faith to overcome all the hurdles you face. May you have a great year and a wonderful time ahead.
Thank you so much!
I am designing a Chipsat. It might cost 200€ or lower for a launch – depending on the systems on board.
But to keep it more interesting than just beeing space junk, I generated a voting for possible subsystems.
What capabilities would you like to have on it?

Help me in the design process by clicking on your wishlist. If you have more suggestions feel free to post.
A prototype will be ready for a balloon test hopefully this month (TX and magnetometer on board)
We would like to invite everyone involved in a CubeSat project to fill in a questionnaire. It will take you between 15 and 20 minutes to complete. The questionnaire is designed to be user friendly and as time effective as possible.
The link to the questionnaire: http://tinyurl.com/njvuywz
The survey is a collaboration between Jasper Bouwmeester from TU Delft and Martin Langer from TU Munich. It focusses on general CubeSat reliability aspects as well as performance and reliability aspects of a CubeSat bus architecture. The results will be used as a major input for our PhD research and will be published in journal and/or conference papers.
As a return favor for your participation, you will receive a de-correlated (anonymized) database from this questionnaire which may be very helpful for your own research and future CubeSat design. You will also receive the associated publications if this is permitted by the publisher, or otherwise the main conclusions. Your participation will enhance worldwide CubeSat research and will help to improve the success rates and designs of future CubeSats.
