About
VECTRONIC Aerospace’s On-Board Data Handling (OBDH) system processes direct and time-tagged telecommands and provides additional spacecraft autonomy through user-defined, event-triggered processes. It performs standard housekeeping data collection, supports configurable digital/analog I/O, and communicates over user-definable asynchronous serial interfaces on RS422/RS485 with adjustable baud rate up to 1 Mbaud. An optional redundant module configuration and umbilical/EGSE interfaces are available. Seven OBDH systems built on this design are currently operating in orbit.
