Specifications

Description

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™ real-time operating system drives the applications running on each of the ARM Cortex-M7 modules.

The module is delivered with an SDK, allowing customers to extend the applications running on the OBC as needed according to mission requirements. It comes pre-programmed with firmware capable of collecting historical telemetry, transmitting scheduled commands, and executing Lua scripts.
