About
This product page from Airbus details various digital payload equipment designed for space applications, particularly for Earth observation satellites. It features the CORECI 2, a high-performance integrated compression, recording, and ciphering equipment that has been in flight since 2021, offering enhanced performance and maintaining high standards of quality and reliability. The NEMO-2 2041 is presented as a compact solid-state recorder providing high-end mass memory storage and performance, benefiting from over 30 years of Airbus Defence and Space’s flight heritage in solid-state technologies. The IDCU (Integrated Data Control Unit) is described as a component located on the Satellite Platform, responsible for the encryption, decryption, and authentication of Telecommand (TC) and Telemetry (TM) data handled by the On-Board Computer (OBC). Additionally, the page highlights a high-performance data processor, characterized as a building block for very high reliability and radiation-hard data processing, capable of sustaining high data throughput and offering flexibility for adapting to emerging standards. Instrument control units are also mentioned, providing turn-key end-to-end solutions with basic functions like processing, standard general-purpose interfaces, power conditioning, and thermal control, with dedicated application modules for specific instrument needs.
