ITF-1 CubeSat – Imagine The Future

University of Tsukuba ITF-1 (YUI) CubeSat

University of Tsukuba ITF-1 (YUI) CubeSat

Students at the University of Tsukuba are working on the ITF-1 (YUI) CubeSat project that is planned to be launched on a H-IIA rocket in the fiscal year 2013. The orbit will be 400 by 350km with an inclination of 65 degrees.

The formal name ITF-1 comes from the initial letter of the university slogan “Imagine The Future”.  The satellite also has a popular name YUI which means “bond” in Japanese, it came from the project’s concept‚ “Creating the Worldwide Human Community”.

The 435MHz satellite beacon will send telemetry by a Morse Code audio tone on an FM transmitter running 300 milliwats output. It should be possible to receive it using simple equipment such as a handheld transceiver or scanner. Telemetry information will be first compressed into binary data  and then cut into 5 bits and converted into 10 – 15 Morse codes.

Reception reports will be acknowledged with a certificate and the telemetry will be made available on the web.

QRP APRS Packet Radio to the ISS

International Space Station

International Space Station

Doug Cook KD5PDN’s article about contacting the International Space Station with a few watts and a shoestring budget antenna is now available.

The article “QRP to the ISS” appeared in the February, 2012 issue of QST magazine and, with permission from the ARRL, can be downloaded from Clint Bradford K6LCS’s website.

Doug walks the reader through building a simple tape measure beam, and how to successfully work the ISS with it and a handheld radio.

Read the article at http://www.work-sat.com/Work-Sat/Misc_files/QRP-ISS.pdf

A video by author Doug Cook KD5PDN shows the tape rule antenna and how to set up a Yaesu VX-8R for ISS APRS packet data sending and receiving and other aspects to make a digital contact with the International Space Station. You can also learn how to interpret the audio prompts when packet data is being received.

Student D-STAR Satellite to Launch in 2012

Students at workStudents at the University of Liege are hoping their D-Star GMSK satellite OUFTI-1 will be launched towards the end of this year.

An update on the satellite is published in the January 2012  issue of the OUFTI-1 newsletter at
http://www.leodium.ulg.ac.be/cmsms/uploads/OUFTI-1%20Newsletter%204.pdf

The satellite will have uplinks in the 145 MHz band and downlinks on 435.015 and 435.045 MHz.

Student Software Defined Radio CubeSat

Students at the University of Vigo have built Xatcobeo a CubeSat that carries a Software Defined Radio (SDR) and a solar panel deployment mechanism.  A launch on an ESA Vega rocket in February is planned.

The IARU Amateur Satellite Coordination Panel pages report that it carries three payloads:

SRAD: a Software Defined Radio. The aim is to test under space conditions a reconfigurable radio. Different modulation schemes will be selected depending on the link conditions.

RDS: an ionizing radiation dosimeter. This dosimeter will take measures of ionizing radiation in a typical LEO orbit for amateur satellites, thus increasing our knwoledge about radiation conditions in this environment.

PDM: a solar panel deployment mechanism to be tested in-flight.

It is planning to use FFSK with AX.25 on UHF. These frequencies have been coordinated – Simplex 437.365MHz and SSR downlink on 145.940MHz.
