Video of HTV-3 Spacecraft and CubeSat Deployer

Kibo Robot Arm CubeSat Deployment

The Japanese H-II Transfer Vehicle “KOUNOTORI” (HTV) is an unmanned transfer vehicle which can carry amateur radio CubeSats along with food, clothes and equipment needed for experiments in the International Space Station (ISS).

“KOUNOTORI 3” (HTV-3) is planned to launch on July 21, 2012 from Tanegashima Space Center and will be carrying four amateur radio CubeSats WE-WISH, FITSAT-1, F-1, and TechEdSat along with the CubeSat Raiko which carries a beacon in KU-Band.

This video, produced by the Japanese Space Agency JAXA, gives an overview of the HTV-3 and its payloads. At  3:56 into the video there is a segment on the JEM-Small Satellite Orbital Deployer  (J-SSOD) that Japanese astronaut Akihiko Hoshide KE5DNI will use to deploy the CubeSats from the ISS. The Software Defined Radio gets a mention at 7:34.

Successful test for the F-1 cubesat

Thu XV9AA  successfully completed on ground long range communication tests with the F-1 bird. The project team is now undergoing the cubesat safety review to confirm its launch by an HTV cargo in late July.

 

 

Successful long range communication test from 50km!

FSpace team has just completed another important milestone by successful performed the long range communication test of F-1 CubeSat to the ground station at a distance of 50km! The team carried the little satellite to top of Tam Dao mountain (about 1300m high), more than 50km from the ground station at FPT building in Hanoi. Despite of heavy fog and high humidity (which was very bad for radio communication) the ground station successfully sent uplink commands to F-1 and the satellite responded correspondingly, reporting its status and taking some photos.

On the long way up…

Test successful, let’s have a group photo!

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.

Vietnam Student CubeSat F-1

Vietnamese students have produced a video about their amateur radio CubeSat F-1, callsign XV1VN.

The F-1 is an educational CubeSat to be launched in the summer of 2012. It will carry a low resolution C328 camera with 640×480 resolution and two Yaesu VX-3R transceivers using 145.980 and 437.485 MHz.

•VX-3R1
–Frequency: 437.485MHz, FM Narrow
–Power supply: directly from solar cells, only operates in sunlight
–Output power: max 0.3W, half-wave dipole antenna
–Modulation scheme: Morse code beacon (10 chars) using PWM CW
–Beacon interval: every 30 seconds (configurable)

•VX-3R2
–Frequency: 145.980MHz , FM Narrow
–Power supply: rechargeable battery, operates in the dark by default but can be commanded to operate in sunlight as well
–Output power: max 1.0W, half-wave dipole antenna
–Modulation scheme: AFSK 1200bps, half duplex
–Telemetry interval: one AX.25 packet every 30 seconds (configurable)

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).
