William A. (Bill) Tynan, W3XO, OSCAR Number Administrator has conferred on Shin’en2 the designation Fuji OSCAR-82 or FO-82.

Shin'en 2 (FO-82) also known as Abyss 2

Shin’en 2 (FO-82) also known as Abyss 2

In reply to Seiji Fukushima’s, JH6RTO, request for an OSCAR number, Bill said, “I along with all in AMSAT-NA and the world’s Amateur Radio satellite community congratulate you and all involved with Fuji OSCAR-82 and trust that it will fulfill all of its mission objectives. FO-82 joins an illustrious line of Fuji spacecraft built and launched by Japan.”

Shin’en2 is a 17 kg satellite measuring 490×490×475 mm built by students at Kagoshima University in Japan. The aims of the mission were:
• To establish communication technologies with a long range
• To establish a new technology of the ultra-light-weight satellite with UHF downlinks

The orbit is quite different from the previous satellites. Shin’en2 headed to a deep space orbit between Venus and Mars. The inclination is almost zero, which means it will 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.

Shin’en2 IARU coordinated frequencies listed as:
• 437.505 MHz CW beacon
• 437.385 MHz Telemetry

Shin’en2 launched in the 4th quarter of 2014 with another amateur radio satellite, ARTSAT2:DESPATCH, on a H-IIA rocket with the asteroid explorer Hayabusa 2 as the main payload.

Ham radio deep space launch postponed again

ARTSAT2:DESPATCH Internal Structure

ARTSAT2:DESPATCH Internal Structure

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.

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 two 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.

Ham radio launches to deep space

ARTSAT2:DESPATCH Internal Structure

ARTSAT2:DESPATCH Internal Structure

ARTSAT2:DESPATCH is going to launch on a mission into deep space on November 30, 2014 carring a 7 watt CW transmitter on 437.325 MHz.

It will fly with the asteroid mission Hayabusa 2 and another amateur radio satellite Shin’en 2.

ARTSAT2:DESPATCH will have an elliptic orbit around the Sun and travel to a deep space orbit between Venus and Mars. Its inclination will be almost zero, which means Shin’en 2 will 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.

The team have released the following information:

1. Despatch CW Format is now available!

Yesterday, we opened a wiki which explains how to join the “Cooperative data reconstruction,” the main mission of Despatch.  In this wiki, you can find the CW format as well as how to report the data you received.
http://despatch.artsat.jp/en/Cooperative_Data_Reconstruction

2. Despatch Tracking page is opened!

Since Despatch is injected into an Earth escape trajectory, TLE is unavailable. Instead, we opened a web-page for the spacecraft tracking (both antenna-pointing and receiver-tuning).
http://api.artsat.jp/pass/

Please go to the page and enter your geographic location, and you will get nearby passes and a table with 1 minute steps that gives you AZ, EL, Freaquency, and so on. As the apparent movement and the change of the Doppler shift are slow, manual pointing of the antenna and tuning of the receiver every 10 minutes or so will do.

3. Reception Report page is opened!

We opened a web page in which you can report the data you received.
http://api.artsat.jp/report/

Thanks in advance and all the best,

Akihiro Kubota, ARTSAT project

Predictions App for Deep Space Ham Radio Satellite

ARTSAT2 DESPATCH Deep Space Sculpture

ARTSAT2 DESPATCH Deep Space Sculpture

Two amateur radio satellites ARTSAT2: DESPATCH (437.325 MHz CW) and Shin’en 2 (145/435 MHz linear transponder + 437 MHz WSJT) should be launched into deep space at the end of November.

Masahiro JI1IZR has announced that prediction software is available for ARTSAT2: DESPATCH:

One of the new deep space small satellites, “ARTSAT2: DESPATCH”, will be launched on the end of this month.

I developed a predict utilities that display the information got from the Web API data provided by the “ARTSAT” project team.

You can get the utilities and information from:
http://ji1izr.air-nifty.com/ham_satellite/in_english/index.html

You will also have the information of the satellite “ARTSAT2: DESAPTCH” from:
