Description
The user requirements on data throughput and –speed of avionic busses are calling for new media. Simplification and reuse of architectures and components to realize cost reduction are requested. In the past, different bus types were used to fulfill the technical requirements: on one hand determinism and exactly time correlated data , on the other hand high performance data management for sensors or payloads. For the deterministic part often the MIL1553 STD is used, limited to a bandwidth of 1Mbit. Ethernet or Space Wire are used for high speed communication. A promising candidate, providing one technology combining both determinism and high speed- for space applications, is the TTEthernet standard used and verified by commercial and aviation industries. This standard is baseline for the NASA’s MPCV/ORION. A spin in of this technology standard, its maturation, the current experience in the frame of space projects (MPCV-ESM) and an industrialization roadmap will be described in the presentation.
