ITF-2 (YUI-2) Satellite Update

ITF-2 Yui ProjectAtsushi Yasuda JI1OEH reports the ITF-2 (YUI-2) CubeSat entered normal operation phase on March 25 JST, it was deployed from the ISS on January 16, 2017.

Update: ITF-2 was giving the OSCAR number Tsukuba-OSCAR 89 (TO-89).

Telemetry information and messages will be transmitted in this phase for the achievement of main mission.

The details of AWARD and SWL cards are:

AWARD：
With reference to the message on January 15 UTC, the First 100 Reports from overseas stations are qualified for this award. Only ten overseas stations sent report so far. Still enough award can be issued. Additionally, a souvenir, a sticky screen cleaner, will be given with this award.

The design motif is the small antenna of ITF-2

SWL cards:
Five designs are prepared. The stations which report more than five times can receive all designs. Also, the specially designed card will be presented to the stations which received a signal from the small antenna, because the reports are valuable to demonstrate the antenna in space. So far, two stations succeeded in the reception.

Further special events are planned for the promotion of receptions by more stations. This will be announced later.

There were some reception reports by very simple equipment, for example, Dipole or 5/8 wave length whip with USB tuner dongle (RTL2832).

The examples are

Ham Radio Satellites at Tokyo Ham Fair

The JARL Ham Fair 2013 was held at Tokyo Big Sight, Ariake, Tokyo on August 24-25. JAMSAT and several amateur radio satellite projects were represented.

The University of Tsukuba CubeSat ITF-1 YUI “Binding” support project was there. 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 or binding in Japanese, it came from the project’s concept‚ “Creating the Worldwide Human Community”.

The ITF-1 satellite beacon on 437.525 MHz 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.

According to the ITF-1 website the “Binding” support project is organized by the student volunteers to support the construction of a consolidated network and expand public relation activities with the aim of encouraging many reception reports when the satellite is launched.  ITF-1 will fly with the primary payload the Global Precipitation Measurement Dual-Frequency Precipitation Radar GPM-DPR satellite in 2014.

The ARTSAT stand featured the Invader CubeSat which is being developed by students at Tama Art University. The IARU has coordinated 437.325 MHz and 437.200 MHz for Invader which aims to have a camera for Earth imaging and a Digi-Talker, to transmit voice data using FM. Invader will be on the same launch as ITF-1.

Also at the fair was the SPROUT project. This nano-satellite, built by students from Nihon University, is 20 x 20 x 22 cm with a mass of 6.7 kg. It plans to launch with the L-band (1236.5 MHz/1257.5 MHz/1278.5 MHz) Synthetic Aperture Radar (SAR) satellite ALOS-2 in December, 2013.

SPROUT will have a digi-talker and will transmit, using Slow Scan TV (SSTV) and FM packet, pictures of the Earth taken by an on-board camera. It is believed that radio amateurs will be able to make use of the digipeater and possibly even command when pictures are taken.

ITF-1 CubeSat – Imagine The Future

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.
