Space Applications

VEGA launcher is designed to launch small payloads — 300 to 2,500 kg satellites for scientific and Earth observation missions

A subsystem of VEGA consists in an electromechanical system, the Thrust Vectoring Control (TVC) System, that tilts the nozzle of each engine of the four stages in order to steer the rocket. Each TVC system possesses its control and power electronics., SABCA thus has the responsibility of pointing the nozzles of each engine in the right direction as determined by the on-board computer.
