OBC-M7

Versatile Onboard Computing Platform

Space Inventor

The OBC-M7 is an onboard computing platform consisting
of two independent ARM Cortex-M7 modules, each with
separate power supply, interfacing, and storage. The dual
architecture makes the OBC-M7 a suitable choice for
hot/cold redundancy solutions often desired for mission
critical subsystems, such as T&C, GNC, or management of
valuable payloads. The application of the OBC-M7 is further
enhanced by the powerful DSP functionality provided with
the Cortex-M7 architecture, which makes it possible to port
heavy floating-point processing such as ADCS or RvD
algorithms without severe performance penalties and
error-prone quantization. If redundancy is not required, the
OBC-M7 provides a advantageous platform for combining
different subsystem functionality, such as ADCS and T&C,
in a compact form-factor.
