During the Microwheels II project three objectives were pursued:
In the preceding project Microwheels, reaction wheels were newly developed, which were successfully tested in a low Earth orbit. As testbed, the picosatellite BEESAT was designed with a mass of less than 1 kg and manufactured and verified at TU Berlin
On 23rd September 2009 BEESAT was launched aboard the Indian launcher PSLV-C14 into a sun-synchronous orbit (altitude ≈730 km, inklination 98.3°).
Since then, numerous experiments have been conducted with the reaction wheels. Satellite operations and data evaluation are also conducted at TU Berlin. The originally scheduled mission duration of one year was exceeded by more than 3 years - BEESAT is still operational today. The satellite's telemetry provides valuable data, not just with regard to technical testing of the reaction wheels in orbit.
With the achievement of the stated objectives, important contributions to the creation of a reliable system standard for future pico- and nanosatellites for different applications have been made.
