NetAcquire systems support the SpaceWire (IEEE
1355) data bus I/O protocol. SpaceWire is commonly used as a spacecraft
communications bus – it offers high speed (400 Mbps), very low error rates,
deterministic system behavior, and low power consumption.
The NetAcquire SpaceWire option provides four
bi-directional SpaceWire channels with options for additional channel expansion.
This option leverages the full power of the NetAcquire architecture including
real-time network routing, message parsing, data recording, traffic simulation,
and bit error rate testing. SpaceWire-unique capabilities are also supported,
including time code packet generation with cross-channel propagation and
packetized/non-packetized streams.
Applications for the NetAcquire SpaceWire option
include satellite vehicle test, avionics hardware emulation, network data
distribution, and communications gateways.
