Integrated Avionics Unit

Moog鈥檚 Integrated Avionics Unit (IAU) offers solutions for Command and Data Handling/Electrical Power Subsystem (C&DH/EPS) for a full range of spacecraft and payload applications. Configurations include single string and redundant systems. The IAU leverages TRL-9 legacy heritage with options for tailoring and/or customized new designs to meet mission requirements. The IAU is optimized for orbit and radiation requirements and utilizes traditional EEE parts in Level-1, -2, and -3 part grades.
