Key highlights
The OBC is an onboard computing platform consisting of four independent ARM Cortex-M7 modules, each with separate power supply, interfacing, and storage. The quad architecture makes the OBC a suitable choice for hot/cold redundancy solutions often desired for mission critical Equipment, such as T&C, GNC, or management of valuable payloads. The well renowned FreeRTOS(tm) real time operating system, drives the applications running on each of the ARM Cortex-M7 modules.
