Launcher electronics

Sequential electronics (Ariane 5):

Centralized Multi-Functional Unit (CMFU) (Ariane 6):

• On-board computers (functional and telemetry), based on ARM Cortex R5 microprocessor
• Time-triggered ethernet switch
• Electro-valves and loop closure commands
• Power distribution

Pyrotechnical Firing Unit (PFU) (Ariane 6):

• Electro-Explosive Devices (EED) commands
• Laser-Initiated Devices (LID) commands
• Includes all the safety barriers

Batteries (Ariane 6):

• Product based on commercial cells
• High production rate
• Batteries assembly facility for Ariane 6 fully operational in 2023

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
