ARTSAT2-DESPATCH signal received

The amateur radio spacecraft Shin’en2 JG6YIG and ARTSAT2:DESPATCH JQ1ZNN were successfully launched on their journey to deep space at 04:22:04 UT on Wednesday, December 3, 2014 and signals from both spacecraft have been received.

They were on the H-IIA Launch Vehicle No. 26 (H-IIA F26) which also carried the asteroid explorer “Hayabusa2”.

The two amateur radio spacecraft will have an elliptic orbit around the Sun and travel to a deep space orbit between Venus and Mars. The inclination will be almost zero, which means the spacecraft should stay in the Earth’s equatorial plane. The distance from the Sun will be between 0.7 and 1.3 AU. An Astronomical Unit (AU) is 149,597,871 km.

ARTSAT2:DESPATCH has a 7 watt CW transmitter on 437.325 MHz and is also the first 3D printed sculpture to be carried into deep space.

Shin’en2 has a CW beacon on 437.505 MHz (0.1 watt) and telemetry on 437.385 MHz (0.8 watt) using a mode which Seiji JH6RTO describes as similar to WSJT but not the same.

The Shin’en2 English language Ground Station page mentions WSJT but the equivalent Japanese language page does not.

The Shin’en2 site indicates there is also a F1D digital transponder with an uplink of 145.942 MHz with 435.270 MHz (0.4 watt) downlink.

The launch of the amateur radio spacecraft Shin’en2 JG6YIG and ARTSAT2:DESPATCH JQ1ZNN has again been postponed and should now be 04:22:04 UT on Wednesday, December 3, 2014. The launch was broadcast live at https://www.youtube.com/watch?v=o5TmrQ_ySfg starting at 03:30 UT.

Update: Launch was successful http://global.jaxa.jp/press/2014/12/20141203_h2af26.html

The launch of the H-IIA Launch Vehicle No. 26 (H-IIA F26) which also carries the asteroid explorer “Hayabusa2” had been rescheduled from November 30 to December 1 due to a freezing layer in the clouds that exceeded the weather restrictions for launch. Strong winds have caused a further postponement to December 3.

ARTSAT2:DESPATCH carries a 7 watt CW transmitter on 437.325 MHz and the first sculpture to be carried into deep space.

Shin’en2 has a CW beacon on 437.505 MHz (0.1 watt) and telemetry on 437.385 MHz (0.8 watt) using a mode which Seiji JH6RTO describes as similar to WSJT but not the same.

ARTSAT1:INVADER Reception Reports Needed

ARTSAT INVADER Team Members

ARTSAT INVADER Team Members

Masahiro Sanada JI1IZR reports the amateur radio CubeSat ARTSAT1:INVADER (CO-77) is in trouble and asks radio hams to listen for the satellite and report any reception.

ARTSAT1:INVADER

ARTSAT1:INVADER

ARTSAT1:INVADER, one of the CubeSats, is in trouble that the satellite does not reply after the command by the command station.

The members are trying to find out how to recover.

We have no reply from the satellite, nor the CW [437.325 MHz] becomes not to be heard after the command.

When you have a chance to listen to the satellite, please send your report via the form at:
http://api.artsat.jp/report/

Your report will be great help for the members.

We appreciate your help very much.
Thank you.

INVADER is an amateur radio “Art Satellite” developed by students at the Tama Art University as a part of the “ARTSAT: Art and Satellite Project” which aims at a practical use of a satellite for art and design.

The 1U CubeSat was launched from the Yoshinobu Launch Complex at the Tanegashima Space Center on Thursday, February 27 at 1837 UT. It carries a CW (A1A) beacon on 437.325 MHz (+/- 10 kHz Doppler shift), a 1200 bps FM AX.25 Packet Radio and FM Digitalker on 437.200 MHz and a low-resolution camera.

Art and Ham Radio in Deep Space

ARTSAT2 DESPATCH Deep Space Sculpture

ARTSAT2 DESPATCH Deep Space Sculpture

Students at the Tama Art University are planning to send a sculpture ARTSAT2 DESPATCH along with an amateur radio payload into deep space.

ARTSAT students at the Tama Art University

The ARTSAT2 Deep Space sculpture “DESPATCH” is planned to launch in mid 2014 on a H-IIA rocket with the asteroid explorer Hayabusa 2 as the main payload. Hayabusa 2 will be making a round-trip to the C-type asteroid 1999 JU3 arriving at the asteroid in mid 2018.

The sculpture, which is 50 by 50 by 45 cm with a mass of 30 kg, was developed at the Tama Art University using a 3D Printer. The containment vessel will carry a CW beacon in the 435 MHz band using an omni-directional antenna. The satellite should provide the ultimate in ham radio DX reception when at its maximum operational distance of 3 million km from Earth about a week after launch. Being battery powered without solar panels it will have a low transmit cycle to maximize the lifespan.

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.
