OBC-S is an onboard computer featuring second-generation OBClite™ technology. It offers, for example, increased CPU speed, RTEMS real-time operating system (RTOS), and a SpaceWire interface. Triple-modular redundancy (TMR) on FPGA gates and error detection and correction (EDAC) on memory make OBC-S fault tolerant to single event effects. OBC-S is equipped with many peripheral interfaces, allowing it to act as a Remote Terminal Unit (RTU) that can interface to various sensors and sub-systems in parallel. The unit has analog inputs with 24-bit resolution (approx. 17-bits effective at highest sample rate) and comes with six RS422 serial ports for custom use.
