BEESAT-2 is a pico satellite mission hosted by the Chair of Space Technology of Professor Dr.-Ing. Klaus Brieß. The satellite was built according to the CubeSat design specificationby staff members of the Chair of Space Technology with active participation of students. Major components of the satellite bus had already been designed during the precursor mission BEESAT-1. These components form the space proven technological basis of the satellite BEESAT-2.

The primary scientific objective of the mission is the technical verification of an innovative attitude control system for picosatellites under space conditions. Miniaturized reaction wheels are used as actuators. Those reaction wheels were already verified successfully on orbit during the research project "Microwheels II".
