More About ARISS

ARISS was created and is managed by an international working group, including several countries in Europe as well as Japan, Russia, Canada and the USA. The organization is run by volunteers from the national Amateur Radio organizations – including Radio Amateurs of Canada – and the international AMSAT (Radio Amateur Satellite Corporation) organizations from each country.

Since ARISS is international in scope, the team coordinates locally with their respective space agency and as an international team through ARISS working group meetings, teleconferences and webinars.
