Description
The scope of the second day of ADCSS is focused on the challenges and opportunities of having higher integration of functions in to the on-board computer as opposed the more traditional distributed architecture. OBC equipment suppliers will give their views on challenges and opportunities with current state of the art building blocks and future needs. The following topics will addressed in the round table:
- How will moving to a more centralised and integrated avionics architecture affect testing, and is it contributing to costs saving? As an example; integrating functions into to the OBC effectively moves testing of unit functionality, e.g. provided be Start Trackers or Internal Measurement Unit supplier, from system level testing to become the responsibility of the OBC supplier. Further is higher integration a trend that should be followed even on single shot missions, taking profit of new H/W and S/W computer features (high CPU performance & large memory capacity, TSP), with the benefit of reduced mass?
- Will the high integration of powerful processing and memory components make our future designs decentralized again?
- Shall we use new processing capabilities to design fault tolerant systems using COTS components even for critical time systems (Platform/AOCS) or is it still too early?
- It is considered mandatory to calculate the reliability of the avionics unit, however at present there is insufficient reliability data on use of COTS components and technologies (e.g. use of ceramic vs. plastic packaging) to be able to estimate unit reliability. How do we best ensure that the introduction of COTS parts do not adversely affect the unit reliability?
