Multi-functional unit (VEGA-C):

Based on Airbus Defence and Space heritage in the development of launch vehicles MFUs, this MFU has been specifically developed for VEGA-C, although its modular concept would allow the reuse of modules in other launchers.

Key assets:

  • 1553 bus repeater
  • Power source – ground / onboard – management. Interfaces with 7 different batteries
  • Avionics’ power distribution
  • Effectors’ driving (electro-valves, loop closure commands, EEDs, NEAs)
  • Wide range of payload services (Electrical orders, NEAs, 1553 bus…)
  • Safety function management
  • Interface with ground control bench by means of RS-422


Upper stage harness (VEGA-C):

  • Most of the DC harness in VEGA-C’s upper stage (AVUM)
  • The entire MIL-STD-1553B harness in the launcher (all the stages)
  • Routing in the 3D electronic mock-up
  • 58 wire bundles
