Satellite Management Equipment
The Satellite Management Equipment is a powerful, reliable and robust flight computer compatible for different space orbits. Thanks to its highly reliable LEON3 processor architecture and modular equipment structure, UYE can be adapted to different space platform requirements.
UYE brings the following features to the satellite space segment:
- Processing power and peripherals for flight mission software
- TM-TC services and interfaces for RF communication chain
- Control and monitoring of Satellite Equipment using MIL-STD-1553B and CAN buses
- Discrete command and monitoring interfaces compatible with ECSS-E-ST-50-14C
- Time synchronization signal generation and distribution
- Fault tolerant architecture with redundant structure and hardware protection features
