Onboard Intelligent Electronic Unit
Product Introduction
The on-board intelligent electronic unit is the "brain" of a satellite and one of the core products. It undertakes the core tasks of the satellite's normal operation, mission execution, and intelligent processing. It has functions including TT&C (Tracking, Telemetry and Command), satellite service, GNSS, attitude and orbit control, data management, storage, data transmission, on-board intelligent computing, information exchange, networking control, autonomous mission management and planning, etc. It is also responsible for the interface management and operation control of all parts and payloads on the satellite platform.
