Beesat-2 (also Tubsat 9 ) is a small satellite (or Cubesat ) of the Technical University of Berlin , which was developed at the Department of Space Technology with the cooperation of students. He is the direct successor to BeeSat . Because of the great success of BeeSat, an almost identical hardware configuration of improved cameras and payload data computers is chosen, which is adapted to the mission objective in a few places.
As part of this research project, miniaturized reaction wheels are used that were developed in the previous project and that have already been successfully tested in space.
During the planned mission period of six months, attitude control experiments are to be carried out for the first time on board a pico satellite using reaction wheels.
The control concept is based on the measurement of the earth's magnetic field and the incident solar radiation . Every half-second, this data is compared on board with calculated reference vectors from mathematical models, from which the orientation of the satellite in space can be determined. State controllers convert this position information into control commands to the reaction wheels and allow the satellite to be aligned in a controlled manner. The result of this position control can be checked by the operating staff on the ground using a built-in camera.
Following this experimental phase of operation, the satellite will be used as part of teaching and should also be used as an amateur radio satellite .
The satellite was launched on April 19, 2013 10:00 UTC from Baikonur together with the biosatellite Bion-M1 and the five small satellites AIST 2 , Beesat-3 , Dove-2 , OSSI 1 and SOMP with a Soyuz 2.1a rocket .
Beesat-4 was developed on the basis of Beesat-2 and was launched on June 22, 2016.
