ARSPEX
WG
2006
ACTIVITY REPORT
Presently the main
activity of the ARSPEX working group is related to ARISS, Amateur Radio on the
International Space Station.
ARISS has
developed a privileged relationship with the Space Agencies: NASA,ESA and
Roscosmos/Energia.
Astronauts and
cosmonauts – most have an amateur radio licence – use the amateur radio VHF
station on board the Russian modules for contacts with ground stations
worldwide.
The main activity
is educational outreach, which is the most appreciated by the Space Agencies. ARISS
international has developed an efficient system for organizing school contacts:
students prepare questions and have the possibility to put their question to an
astronaut onboard the ISS over amateur radio, and get his/her answer from space
real time.
ARISS mentors work
with local amateur radio clubs (mostly by e-mail and phone) to set up an
efficient satellite type station in the schools selected for a contact. In
Region 1, ARISS-Europe has mentors in UK, Belgium, France and Italy.
When a direct radio
contact cannot be set up, the radio contact with the ISS is established by one
of the ARISS dedicated ground stations and from there, the signals are relayed
by phone to the school. This solution is called a “telebridge”. Verizon
Conferencing, Inc offers the phone link which generally involves up to ten
hams: the astronaut, the ground station operator, the operator in the school,
the coordinator, a moderator and the hams in charge of broadcasting the audio
of the space talk over EchoLink and IRLP.
In 2006, eight ARISS School Contacts were performed in Region 1:
-
2 in Germany
-
2 in Italy
-
1 in Kuwait
-
1 in Switzerland (on
request of ESA)
-
1 in Belgium
-
1 in Sweden (on
request of ESA)
Several school
contacts are on the European waiting list and some will be performed in 2007.
ARISS
international recently transformed a discarded Russian spacesuit into an
amateur radio satellite (called a “SuitSat”) which was launched by hand from
the ISS during an EVA (Extra Vehicular Activity). The onboard VHF transmitter
broadcast recorded messages from students in five languages to the youth of the
world. The signals were weak but the event was a media success worldwide.
ARISS presently
prepares a second “SuitSat” with extended possibilities.
ARISS-Europe has
received permission from ESA to install amateur radio antennas on the European
space laboratory
The L/S-band
antennas will be fixed on the nadir of
The patch antennas
are developed by the Technical University of Wroclaw, Poland.
Technical
constraints are extremely severe, due to the intense vibrations the antennas
will have to withstand during launch in a Shuttle bay.
ARISS-Europe has
collected 50.000€ for the construction of the antennas. The initially estimated
cost was 80.000€, but the real price will be higher. The University has
received support for this project from the Polish Ministry for Science and
Research, but 20.000€ are still needed to finish the work. A contribution from
the societies and/or the Region would be most welcome.
ESA also
contributes to this project, supporting the installation cost (feedthroughs,
coax cables, fixation on the module). The installation cost supported by ESA
amounts to well over 100.000€.
ARSPEX chairman calls the Region 1 societies to nominate a delegate to
the working group.
Activities will be discussed and prepared mostly by e-mail and
teleconference.
An ARSPEX page will be added to the IARU Region 1 website.
