The scientific and educational satellites SiriusSat-1 and SiriusSat-2 were assembled by schoolchildren in cooperation with SPUTNIX specialists on the basis of the nanosatellite platform OrbiCaft-Pro developed by the company. The platform has a standardized international standard size CubeSat 1U. The satellite SiriusSat have been further developed to meet the specifics of launch: they have a handle for launching an astronaut, flexible antennas, a system for the manual activation of spacecraft, and also equipped with specially designed protective quick-release covers and soft shipping containers. The weight of each satellite is about 1.45 kg. The payload of the satellite is a space particle detector for studying „space weather“. The sensor was developed by the Research Institute of Nuclear Physics of the Moscow State University and was assembled with the participation of a group of schoolchildren from the Sirius Educational Center.

Four Russian satellites (SiriusSat-1/-2, Tanusha-3/-4) with amateur radio payloads were deployed from the International Space Station on Wednesday, August 15 during a spacewalk (EVA-45) by Sergei Prokopiev and Oleg Artemiev.

Congratulations to the winners!

We congratulate the winners of our small competition among radio amateurs for the reception of the first signals from the satellites SiriusSat-1 and SiriusSat-2. The winners of the competition were as follows: Rocco Valenzano (W2RTV, USA), Anton Janovsky (ZR6AIC, South Africa), Vladimir Chyorny, (EU1SAT, Belarus), Mike Rupprecht (DK3WN, Germany) and Dmitry Pashkov (R4UAB, Russia). It’s worth noting that the radio amateurs not only received the first signals, but they also strongly helped with the dissemination among the radio amateur community of information about the reception of data and the establishment and activation of our specially developed software system allowing the decoding of data and the reception of telemetry from the spacecraft. The winners will receive a QSL card, a copy of the checklist employed by cosmonauts for activization of the spacecraft prior to release and also books on space. Vladimir Chyorny has already been given Chris Hadfield’s book „An Astronaut’s Guide to Life on Earth“ personally in Minsk, Dmitry Pashkov will be sent Stephen Hawking’s book „A Brief History of Time,“ and foreign amateurs will receive Pavlov Shubin’s illustrated album „The Space Rocket System N1-L3.“
