Amateur Radio Assistance Requested: ISS Plasma Thrust Shadow Experiment

International Space Station

International Space Station

The Central Research Institute of Machine Building (TSNIIMASH) in Russia is conducting a series of space plasma experiments in order to evaluate the shape of previously observed “dead” zone, or shadowing due to the firing of an onboard arcjet plasma source.

Radio Amateurs are invited to participate in the Space plasma experiment “Shadow” onboard the International Space Station (ISS) taking place Nov 25-28 and Dec 2-5.

Integration of Electric Thrust (ET) onboard a spacecraft poses a certain set of problems including electromagnetic compatibility of ET. One matter of interest is that highly ionized exhaust plumes of ET may scatter RF-signals producing large “dead” zone for communications. Continue reading →

UHF Station on ISS Columbus module

The amateur radio station located in the Columbus module is currently operational with the UHF Ericsson FM transceiver and AX.25 packet system using the frequency of 437.550 MHz.

To utilize the the packet system, operators need to set the UNPROTO path to ARISS (the id is RS0ISS) for digi relay or they may connect to the BBS using the callsign RS0ISS-1.  The packet beacon is set for 2 minute intervals so it may not appear to be active over many parts of the world but keep listening and mind the Doppler shift (+ or – 10 kHz).

To check when the ISS is in range see the real time tracking at  http://www.issfanclub.com/ (top left).

Deployment of ARISSat-1/KEDR satellite expected August 3

Deployment of ARISSat-1/KEDR satellite expected August 3

After a postponed deployment in February from the International Space Station (ISS), the ARISSat-1/KEDR amateur radio satellite is expected to begin its mission on August 3, 2011. This was the word received from Energia official, Sergey Samburov during an ARISS teleconference on July 19. Deployment of the craft is planned during EVA-29.

NASA TV will cover the EVA live starting at 1400 GMT on August 3.

ARISSat-1/KEDR is a satellite designed and built by amateur radio operators to specifically interest students in scientific and technological careers. Through the use of ham radio equipment, students and teachers should be able to access and utilize the satellite from a classroom environment with minimal set up.

ARISSat-1/KEDR is a cooperative effort between AMSAT, ARISS (Amateur Radio on the International Space Station,) RSC-Energia (The Russian Space Agency) and NASA. The design, development and construction of the satellite was done by AMSAT volunteers. Original plans called for the satellite to be housed inside an old Russian spacesuit, but when the suit became unavailable, a spaceframe was developed to house the radio equipment and solar panels. The new satellite was named ARISSat-1/KEDR. Another name for the spacecraft is RadioSkaf-V. The transmitted callsign will be RS01S.

The mission was specifically designed as an education-based satellite.

Some of its broadcast features include a voice identification, voice, digital and morse code telemetry, stored image and on-board camera transmissions via Slow Scan TV and digital telemetry from a Russian science experiment that will measure vacuum in earth’s lower atmosphere. Other aspects of the mission include CW (Morse code) and voice message contests to interest students in participating along with stored images submitted by students all over the world as part of its payload.

Lough Erne Amateur Radio Club congratulates South West Regional College on its very successful Amateur Radio link up with the International Space Station.

Particular credits to Mamraz Nagi whose initiative secured this ARISS event, the College technicians, and the students who spoke with the Radio Amateur in the ISS, Ronald J Garan, KF5GPO. Among his replies to the Enniskillen students’ questions, he shared very happy memories of a recent visit to Northern Ireland.

David Taylor operated the ground station K6DUE in Maryland USA linking up to the ISS, and Gaston Bertels ON4WF in Belgium, guided the College ARISS team through checks, rehearsals student questions and wrapped up with remarks that brought massive applause from over a hundred present for the radio amateurs in space and on the ground, and all involved in Northern Ireland’s first ever ARISS event.
