Designed for testing the platform and flight testing of the gas propulsion system of OKB Fakel.


16 different satellite missions within the framework of the Space-PI project with the participation of students and schoolchildren.
The first private satellite from St. Petersburg was developed by Geoscan. It is designed for flight testing of the Geoscan 3U satellite platform. The device will study the possibility of transferring nanosatellites to lower orbits using a gas propulsion system (GPU) to reduce the amount of space debris in orbital space. The GDU was manufactured specifically for CubeSat devices at the Fakel experimental design bureau. Nitrogen is used as the working fluid. 
The satellite also has a board with a GNSS receiver developed by the ELVIS Research and Production Center and a silicon wafer with the names of participants in the Send Your Name into Space campaign, which was held by Geoscan in the fall of 2021. The plate was lithographed with 22,772 names. 
This 3U mission is to test CubeSat platform: to get an experience and to educate ourselves in making and operating Cubesats. Our main goal is to create a platform for educational and popularization activities, like engineering, programming and radio amateur communication. Working with universities and middle-school students we want to give them motivation to participate in CubeSat development and operation process. Also, the goal is to get experience as radio-amateurs and to popularize this knowledge to local amateurs. We would like to see our mission as self- training platform for our operator and local radio-amateurs to operate the satellite and ground station. This mission will serve radio amateurs around the globe in many ways. We already have our own QSL cards to give to amateurs which would like to communicate with our satellite. Firstly, it will translate CW Morse code. Secondly, telemetry information will be shared in AX25 packets to all radio amateurs and networks, and everyone will be able to receive and decode our telemetry data, what we really anticipate. Packet format and decoder for our messages will be freely available on our website: as well as on SatNogs database. Our website will also update with more information for amateurs to communicate with Geoscan-Edelveis during the mission. Our systems have ability to be updated from the Earth if needed.
