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.

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.

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.

Thanks in advance and all the best,

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:

I appreciate your notice for the project.

Thank you.

Shin-En2 satellite

Shin-En2 is a 17 kg satellite measuring 490×490×475 mm built by students at Kagoshima University in Japan that will carry a 145 to 435 MHz linear transponder into a deep space orbit.

The aims of the mission are:
• To establish communication technologies with a long range as far as moon.
• To establish a new technology of the ultra-light-weight satellite. Proposing a WSJT 29dBm UHF downlink and a 29dBm 20 kHz linear transponder and a CW beacon all on UHF with a VHF uplink for the transponder

The orbit will be quite different from the previous satellites. Shin-En2 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-En2 will stay in the Earth’s equatorial plane. 

The distance from the Sun will be between 0.7 and 1.3 AU, where AU (Astronomical Unit) is approximately 1.5 x 108 km.

Shin-En2 is expected to launch 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.

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

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.
