Japanese art is very high
December 3 The Japanese space probe Hayabusa-2 and MASCOT , the landing module built by the French German space agencies CNES and DLR, set off for the asteroid 1999 JU3. But along with them, the launch vehicle brought out 3 microsatellites, which was not noted by the media.
Shin-en 2, ARTSAT2-DESPATCH, and PROCYON separated after they entered orbit.
Separation (time in UTC):
Hayabusa-2 [6:09:19]
Shin-en 2 [6:15:59]
ARTSAT2-DESPATCH [6:20:09]
PROCYON [6:24:19]
Shin-en 2 is a Kyushu University of Technology project.
')
Designed for testing communication systems for future private missions in lunar orbits and in deep space at distances of about 3 million km. As well as testing the technology of manufacturing spacecraft from carbon fiber reinforced thermoplastics (CFRTP). CFRTP was used in the construction of a spacecraft for the first time in the world. Polyetheretherketone resins were used. From scientific equipment - a device for measuring radiation in deep space.
Shin-en 2 transmits a CW beacon signal at a frequency of 437.505 MHz with a power of 0.1 Watt and telemetry at a frequency of 437.385 MHz (transmitter power of 0.8 W) using a mode close to WSJT, but not the same.
PROCYON (PRoximate Object Close flYby with Optical Navigation) is a microsatellite that returns to Earth for a gravitational maneuver at the end of 2015, and then travels to a near-earth asteroid, near which it must travel at a distance of about 50 km.
The 67kg microsatellite has an ion engine.
DESPATCH (ARTSAT 2)
DESPATCH (DEep SPace Amateur Troubadour's CHallenge) is the second ARTSAT space probe created by a team of over 70 participants from Tama Art University and The University of Tokyo.
ARTSAT2-DESPATCH is the first sculpture made on a 3D printer and sent into deep space. Rate masterpiece can be a 3D model .
DESPATCH has a 7 watt CW transmitter with a frequency of 437.325 MHz. By means of which the probe conveys " generative poetry " and the temperature inside the probe. The antenna is attached to the supporting rod, which is located in the center of the spiral part, made by 3D printing.
The space probe does not use solar energy, so the device will transmit signals for a week, until it reaches a distance of about 3 million km from Earth and does not consume battery power. The device is not controlled from Earth.
In addition to the artistic part of the mission, carried out technical:
Receiving weak signals at such distances is not an easy task and conventional equipment is not suitable. Therefore, there are not so many participants as the organizers would like, but still an international team from Japan, the Czech Republic, Russia, the Netherlands, Austria, Argentina and Poland turned out.
The organizers published the data summarized in one table , which shows the date of data acquisition, the distance at which the probe was located, the country where the receiving station and the radio amateur's call sign are located. The last lines of the table now look like this:
Call Sign, Date, Range [x10,000km], Country
LU2DDU 06/12/2014 05:11 124 Argentina
UA9UIZ 12/06/2014 20:00 149 Russia (Anatoly Alexandrov. Kemerovo region. Probably uses the F9FT antenna)
SQ5KTM 06/12/2014 21:00 150 Poland (Michał Zawada. Mesh parabolic antenna with a diameter of 4.5 m)
LU2DDU 06/12/2014 23:17 154 Argentina (Daniel Augusto Esteban. LU2DDU.- UNLP. University of La Plata. Buenos Aires. Argentina .- SDR + converter + 432-440 MHz preamplifier in antenna. Antenna: 4 x 15 elements Yagi linear polarization)
Here you can see the antenna used by the Polish radio amateur Michał Zawada (callsign SQ5KTM).
PS A new record from the Polish radio amateur - 2316759 km.

In addition to the artistic part of the mission, carried out technical:
- Test parts of the space probe, made by 3D-printing.
- An experiment on the possibility of receiving very weak signals using “cooperative diversity communication” - a method in which fragmented transmissions transmitted by a spacecraft were received not only by their own ground station in Tokyo, but also by many amateur radio stations in different parts of the Earth, were collected and the original data transmitted by the spacecraft.
Receiving weak signals at such distances is not an easy task and conventional equipment is not suitable. Therefore, there are not so many participants as the organizers would like, but still an international team from Japan, the Czech Republic, Russia, the Netherlands, Austria, Argentina and Poland turned out.
