Deterministic SpaceWire Networks
SpaceWire-D is an extension to the SpaceWire protocol that adds deterministic capabilities over existing equipment. It does this by using time-division multiplexing, controlled by the sequential broadcasting of time-codes by a network manager. A virtual bus abstraction is then used to divide the …

High Performance and Reliable Gbps Spacecraft Data Handling System
Synthetic Aperture Radar (SAR) and super-resolution (fine spatial/spectral) optical remote sensing payloads, onboard Earth observation, science, and planetary missions generate a large amount of data at multi-gigabit per second. The output data rate from state-of-the-art SAR and imaging sensors can …
