MarconISSta experiment identified ON4ISS signals

The project leader and initiator of MarconISSta, Martin Buscher DJ1MBB, has requested some support to help categorise the antennas on the ISS.  The ARISS telebridge groundstation ON4ISS reacted immediately and transmitted at different ISS passes the desired signal to the ISS.

ARISS-Europe News Bulletin > 2500 subscribers

The ‘ARISS-Europe News Bulletin mailing list’ was launched in 2001 with the announcement via email of planned ARISS contacts that are audible in Europe. Gaston Bertels, ON4WF, took at that time the initiative to inform some interested people by email about ARISS activities relevant to Radio Amateurs in Europe.
The success of this initiative obliged Gaston to use a free mailing service ‘Splio’, which automated the management of subscribers and unsubscribers of this service. The free service stopped by applying the European privacy rules ‘GDPR’ by their management on 31 December 2017.
AMSAT-ON developed a tool in early 2018 that will manage and distribute the ARISS-Europe news bulletin. The ‘Spam’ secure sending of mass email like the ARISS-Europe News bulletins requires a complex SMTP server. Currently there are more than 2500 subscribers for that bulletin.
After 17 years, the ARISS-Europe News bulletins are still being prepared by Gaston, ON4WF, and now archived by Francesco De Paolis, IK0WGF, on the ARISS Europe website.

During this summit the educational aspect of ARISS contacts was illustrated with examples by SSE participant organizations such as Magnitude i.o, Student Spaceflight Experiments Program, Storytime from Space, ISS Above, Tomatosphere.

During their break the participants of the summit watched live the ARISS contact with OR4ISS (Alexander Gerst, KF5ONO) and between ON4NOK, St-Jozef College in Turnhout (Belgium) at 12:04 UTC on Thu 16 oct 2018.

The summit ended with a tour in NASA’s Goddard Space Flight Center and a visit to the ARISS telebridge ground station K6DUE.

ARISS telebridge contact in India via ON4ISS

The ARISS contact on Monday 2018-08-27 at 08:06 UTC 88 deg with OR4ISS and Shri Timli Vidyapeeth, Devikhet, India, via ARISS telebridge ground station ON4ISS (Aartselaar, Belgium) was successful. AOS was at 13:36:33 IST (08:06:33 UTC) and LOS 13:47:12 IST (08:17:12 UTC). Astronaut Ricky Arnold KE5DAU answered all 16 questions from students of Timli Uttarakhand, India.

There were about 25 students attending the contact and also some official representatives from nearby villages. The school itself is located in the Himalay area of India, not very high up as they say, only 1700 meters (5577 feet). Some students and invited persons were not able to attend because of the heavy rain in Pauri Garwhal area and road conditions since the last rain showers. Students of GIC Chelusain, GIC Devi khet, Aadarsh Bal Bharti Chelusain and Shri Timli Vidyapeeth participated in this conversation, an historic moment for Uttarakhand, India.

Kenneth Ransom N5VHO explains the ARISS scheduling

On October 14th 2017, at the AMSAT-UK International Space Colloquium in Milton Keynes, Kenneth Ransom N5VHO told about all aspects of his job. He explains what goes into scheduling an ARISS school contact and told about his experiences, his daily struggle, to be able to realize requested ARISS contacts.
It is an interesting lecture, she takes 45 minutes, there are a few technical problems with the microphone, but Kenneth solves that practically.

Questions are plentiful, Kenneth repeats the question and gives a clear answer. View it until the end of the lecture.
