Main Avionics Controller

Moog’s MAC provides Command and Data Handling (C&DH) and Electrical Power Subsystem (EPS) solutions to address LEO and short-duration/technology-demonstration missions. MAC combines the traditional C&DH and EPS functions within a single, low size/ weight/power (SWaP) unit. The MAC derives significant design and functionality from Moog’s heritage TRL-9 Integrated Avionics Unit (IAU). The MAC consists of three (3) circuit cards: C&DH, EPS and DC to DC power converter. The MAC is optimized for orbital radiation requirements and utilizes the appropriate commercial and EEE-INST-002 parts with options for Level -1, -2, and -3 EEE parts programs.
