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
