WOLF - REXUS/BEXUS programme Information

WOLF (WObbling controL system for Free falling unit) is a student experiment developed in the frame of REXUS/BEXUS programme, scheduled for launch in March 2018 on board of the REXUS24 sounding rocket. The primary objective of the project is to demonstrate a system to suppress the wobbling of Free Falling Units (FFUs) ejected from a spinning rocket. Multiple FFUs ejected from a single carrier provide means of multipoint measurements in the upper atmosphere, where spin stabilization is a common attitude control scenario. Lateral rates introduced by rocket coning, ejection tip-off or other effects result in wobbling of FFUs, while for many missions flat spin is required. The REXUS/BEXUS programme is realised under a bilateral Agency Agreement between the German Aerospace Center (DLR) and the Swedish National Space Board (SNSB), through a collaboration with the European Space Agency.
