New Amateur Satellite Frequency Coordination Request Form

IARU Satellite Advisor Hans van de Groenendaal ZS6AKV has made available a new version of the Amateur Satellite Frequency Coordination request form.

Frequency coordination for amateur radio satellites is provided by the IARU through its Satellite Advisor, an official appointed by the IARU Administrative Council, its top policymaking body.

The IARU Satellite Advisor is assisted by an Advisory Panel of qualified amateurs from all three IARU Regions. The panel meets regularly via Skype to consider amateur satellite frequency coordination requests for satellites planned for operation on frequencies in the amateur service. The panel members often provide advice and assist satellite builders with the selection of   the best possible frequencies to meet the objectives of their mission.

The Amateur Satellite Frequency Coordination request form has been updated (Version 27) and is available for download from http://www.iaru.org/satellite.

On the IARU web satellite page there are also available a number of guideline documents which will assist satellite builders, including a document on the ITU requirements for Amateur Radio Satellites.

GOMX-1 to test CubeSat Space Protocol

GOMX-1 is a student built amateur radio 2U CubeSat. The mission is being flown under the auspices of a Government research grant covering space related radio research. It will qualify a number of subsystems and provide extensive in-flight data.

A large number of future amateur/educational CubeSat missions depend on the important data that will be generated by this mission. This will help these mission teams across the globe to achieve higher reliability and improved utilization.

The mission will also test the use of the open source Cubesat Space Protocol (http://code.google.com/p/cubesat-space-protocol/) for a complete mission including the space link.

A camera payload will take color images of the Earth and an experimental Software Defined Radio receiver will be carried and its performance characterized.

More than 15 students at Aalborg University have been actively involved in the development of this payload as part of their semester projects.

It is planning to use GMSK telemetry with selectable 1k2/2k4/4k8/9k6 rates on UHF with approx 28dBm power to a deployed antenna. Launch is expected in late 2012 into a near sun syncronous orbit on a DNEPR rocket from Yasny in Russia with a number of other amateur radio satellites,  see Gunter’s Space Page http://space.skyrocket.de/doc_chr/lau2012.htm

Howard Long G6LVB featured speaker at AMSAT/TAPR Banquet

Howard

Howard Long G6LVB

The AMSAT/TAPR Banquet on Friday night, May 18 is one of the main AMSAT activities during the 2012 Hamvention at Dayton.

AMSAT-NA is pleased to announce that Howard Long G6LVB will be the featured speaker for the evening event. Howard will be talking about his  FUNcube Dongle, the 64 – 1700 MHz Software Defined Receiver.

This innovative USB device is the size of a thumbdrive and has an SMA antenna socket. Multiple SDR control and display software programs can be used with the FUNcube Dongle.

Banquet tickets will not be sold at the AMSAT booth during the Hamvention so reservations must be made through the AMSAT-NA Store http://www.amsat-na.com/store/item.php?id=100158
Tickets are $30 apiece.

Thanks to Gould Smith, WA4SXM for the above information

Radio Amateur Encourages Engineering as a Career

Ali Guarneros Luna KJ6TVO has been involved in the development of the amateur radio CubeSat TechEdSat. In this video she talks to teenagers at a Careers Night about her aspiration to become an engineer.

Watch Career Night – Ali Luna

Ali Guarneros Luna KJ6TVO was born in Mexico City and now lives in San Jose, California. She received her BS in Aerospace Engineering at San Jose State University in 2010 and will complete her MS in Aerospace Engineering from San Jose State University in 2012.

She currently works with the Edison Program, Small Spacecraft Payload and Technologies (SSPT) and SPHERES National Lab at NASA Ames Research Center. Under the Edison Program, Ali works on development of CubeSat projects, including TechEdSat, as the System Engineering, Mission And Ground Operations, and Launch Vehicle Service expert.

Under the Small Spacecraft Payload and Technologies Program, Ali works as Engineering Support for different missions, most currently in NLAS. At SPHERES National Lab, Ali works as Engineer support for Ground Lab and Operation Support.

RAX-2 Success – Anomaly Detected

RAX-2 Detects Comms-Disrupting Anomaly

RAX-2 Detects Communication-Disrupting Anomaly http://rax.sri.com/

Matt Bennett KF6RTB reports that the amateur radio CubeSat, Radio Auroral Explorer 2 (RAX-2), has detected the communication-disrupting anomaly in the upper atmosphere it was searching for. The team have expressed their thanks to the amateur radio community.

RAX-2 was built by students at the University of Michigan. The primary objective of the mission is to use the onboard radar receiver in conjunction with a powerful radar station in Alaska to study the formation of a plasma anomaly known for causing the scintillation of radio signals in the UHF and higher bands. This scintillation effect is known to inhibit our space radar tracking capabilities and ground-space communications. Studying this anomaly in this bi-static radar configuration (ground based transmitter, space-base receiver) will provide scientists with a better understanding of these anomalies that has not been achievable with ground radars alone.

Late on Friday, March 9, Matt KF6RTB announced the news:

This is unbelievable!! After more than three years of hard work and dedication by my team and professor at Michigan, our chief scientist confirmed today that the RAX-2 spacecraft we designed, built, and launched into space has detected the communication-disrupting anomaly in the upper atmosphere that we’ve been looking for!! Cheers guys, we did it!!! GO guys, we did it!!! GO BLUE!!!! [Michigan Athletics battle cry]

The RAX Team would like to acknowledge and say thank you to the amateur radio satellite community for all of their support on this mission. We’ve really enjoyed interacting with fellow operators while collecting and analyzing telemetry. We’ve also learned a great deal about satellite operations from each other.

ISS Symposium 2012 “Research in space for the benefit of humankind”

Radio amateur Andy Thomas G0SFJ has been invited to the ESA ISS Symposium 2012 to be held in Berlin, May 2-4.

The Symposium aims to review and discuss the key accomplishments in research made to date, looking at case-studies in fundamental and applied research and the actual or potential spin-offs for the benefit of humankind, as well as to discuss the future path and priorities for research on ISS.

The Symposium will take place at the Hilton Hotel in Berlin, Germany, starting at 13h00 (after lunch) on Wednesday, May 2, and will run until around 13h00 on Friday, May 4, 2012. Attendance will be free of charge for all invited and registered guests.
