On-board Computer
Robust Design for Small-Spacecraft Applications
Canadensys has developed a new breed of micro and nano-class avionics that deliver the performance and robustness demanded by small missions in deep space without breaking the low-cost paradigm.
With multiple boot ROMs and a redundant bootloader, the Canadensys On-board Computer (OBC) offers high reliability in harsh space environments. The adaptable system design includes a flexible radio interface FPGA with allows connections to user telemetry, tracking, and command hardware. Additionally, a large uncommitted FPGA can be used to implement mission-specific functions or specialized interfaces.
