Two satellites Skoltech B1 and Skoltech B2 are the first in the project "SwarmSat". Satellites were developed and build by engineers at the Skolkovo Institute of Technology. The main experiment of this first launch is to test intersatellite link to enable interaction between two satellites. Additionally, the satellites carry gamma-ray detector DEKOR, developed by the Skobelitsyn Institute of Nuclear Physics of Moscow State University. Joint observation of gamma-rays are planned using connection between the two satellites. This is also a technological demo of many engineering choices made, while constructing the platform. The project is performed in the framework of the "PlanetWatch" and "SpacePi" programs to support involvement of high school students into space exploration and generally support STEM activities in Russia.

Spacecraft Skoltech B1 and Skoltech B2 were design and developed on the basis of satellite platform SkCP-1 (Skoltech CubeSat Platform rev. 1, CubeSat 3U+), were successfully launched into orbit on August 9, 2022 by the Soyuz-2.1b rocket with an upper stage block Frigate from the Baikonur Cosmodrome.
