An avionics data communication network includes a computing device configured to asynchronously transmit data packets in parallel via three or more redundant network interface controllers (NICs). The data packets offered to the avionics data communication network are bound using a token bucket filter (TBF). Three or more redundant network switches are configured to receive and relay the data packets from a different NIC of the three or more redundant NICs of the computing device. An avionics device is configured to receive the data packets from the computing device within a deterministic end-to-end transmission delay bound, the avionics device receiving the data packets via at least one of the three or more redundant network switches.

A system and method for controlling de-orbit of a spacecraft is presented. Embedded command modules are commanded directly from a central command and telemetry module. Latch valves, thruster valves, and solar wing drive of the spacecraft are operated in response to inputs to the embedded command modules. The spacecraft is maneuvered to a safe disposal orbit in response to commands from the central command and telemetry unit.
