The Avionics Embedded System (AES) includes the hardware and software required for the command & control of the spacecraft, its failure detection, isolation and recovery and all the mission and vehicle management functions including all functional chains.
The Avionics Embedded System (AES) includes the hardware and software required for the command & control of the spacecraft, its failure detection, isolation and recovery and all the mission and vehicle management functions including all functional chains. The AES is the brain of the spacecraft and therefore is a vital organ for the execution of onboard functions. It represents today between 30 and 70 % of the platform development costs (50% in average for an ESA mission).
