SpaceTech Satellite Core Avionics SCA
The SpaceTech Satellite Core Avionics combines the Onboard Computer (OBC) and Power Control/Distribution Unit (PCDU) functions in one compact unit. It is a powerful centralized solution for small, 3-axis controlled satellites.
SpaceTech Satellite Core Avionics key features

- Essential resource saving optimized
- Smart, compact and flexible design based on the cPCI-Serial-Space standard
- Powerful, modular and highly integrated avionics solution for small to medium satellite platforms
- SCA architecture open for a full set of AOCS actuators/sensors for 3-axis controlled satellite platforms
- Generic, scalable Single Board Computer (SBC): LEON3, ARM, LEON4
- I/O-module with integrated power distribution for the connected external modules and separate processing power (GR712)
- Supervisor for FDIR and redundancy control
- CAN-Bus as internal/external communication bus
- SpaceWire point-to-point connections where necessary

- Solar Array Regulators (SAR) with MPPT, possible in centralized and de-centralized architecture
- Battery Interface with centralized 12V DC/DC converter
- Power distribution integrated in I/O-modules
- cPCI serial space 6U PCBs for conductive cooling
- Split backplane: cPCI serial space in upper half, mission specific interconnection between the boards in lower half (Zone 0)
