The StratoSat TK-1 spacecraft is a satellite of the «Stratonautics» company, created on the basis of the shortened Geoscan 3U satellite platform.  One of the three units is a transport container for the delivery to еру Earth orbit 6 pico-class spacecraft of the TinySat format ("StratoSat TK-1-A", "StratoSat TK-1-B", "StratoSat TK-1-B", "StratoSat TK-1-G", "StratoSat TK-1-G", "StratoSat TK-1-D", "StratoSat TK-1-E"). 

Picosatellites are presented in two standard Formats: TinySat 1TU - a cube of 5 cm side — four devices, and TinySat 2TU — a parallelepiped with sides of 5x5x10 cm — two devices. They are made by the company «Small Space Systems» for educational programs. 

Each picosat operates with an independent power supply system, has a radio transmitter and a camera on board. The process of the satellites delivered on orbit was filmed on July 11, 2023 with the help of high-resolution photo and video cameras installed on the spacecraft. Two out of three cameras, were developed and assembled by Geoscan LLC: the Geoscan HRCAM-S wide-angle camera for video, the Geoscan HRCAM-M with a long-focus lens used for photographing the Earth.
