JAXA's SDS-4: End of Critical Phase Completed

imageThe Japan Aerospace Exploration Agency (JAXA) would like to announce that the Small Demonstration Satellite-4 (SDS-4) completed its critical phase operations and moved to the initial phase. The SDS-4 was launched by the H-IIA F21 at 1:39 a.m. on May 18, 2012 (Japan Standard Time) as a secondary payload with the Global Change Observation Satellite 1st – Water “SHIZUKU” (GCOM-1.)

The satellite is currently in good health.

The initial functional verification operations will continue for about one month.

IARU agrees 437.525 MHz for ITF-1

Ayano Okamura ITF-1 Project Manager

The Cubesat “Image The Future” ITF-1 build by students at the University of Tsukuba has had the frequency of 437.525 MHz coordinated by the IARU Amateur Satellite Frequency Cooordination panel.

IFT-1 recently underwent thermal vacuum testing.

It 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”.

Japan to Launch Amateur Radio Satellites

Kibo Robot Arm CubeSat Deployment

Kibo Robot Arm CubeSat Deployment

The Japan Aerospace Exploration Agency (JAXA) has announced the launch of five amateur radio satellites on two launches taking place in May and July.

The first H-IIA launch takes place on May 17, 1639-1642 UT and will carry the amateur radio satellite HORYU-2

The second launch on July 21, 0218 UT of the HTV3 will deliver the JEM-Small Satellite Orbital Deployer (J-SSOD) to the International Space Station (ISS).

J-SSOD will enable small satellites to be deployed from the ISS using the Japanese Experiment Module (JEM) robot arm.

The Japanese amateur radio satellites WE-WISH and FITSAT-1, along with San Jose State University’s TechEdSat and the Vietnamese F-1 will also be delivered to the ISS on this launch and it is planned they will be deployed from the ISS on September 20.

TechEdSat to use 'SatPhone'

TechEdSat

TechEdSat

TechEdSat will be deployed from the International Space Station (ISS). It is a 1U CubeSat that will demonstrate Plug and Play power architecture and two way communication via the satellite phone/data networks Iridium and Orbcomm.

UPDATE: The plan to transmit from space using frequencies allocated to Iridium and Orbcomm SatPhone ground stations has been canceled. A statement from the team says: “We were forced to disable the Iridium modem as our FCC license did not come in time. As usual, building the satellite is the easy part.”

There will be a 437.465 MHz beacon transmitting 1 watt to 1/4 wave monopole. Commanding is via the commercial networks and there is a 2 week watchdog timer to stop the beacon in the event of no commands being received.

TechEdSat will be launched along with Raiko, FITSat-1, We-Wish and F-1 to the ISS aboard HTV-3, currently planned to launch July 18, 2012. From there, it will be deployed into Low Earth Orbit  using the JAXA J-SSOD deployer, from the Japanese Experiment Module (JEM also known as Kibo).
