Activity: TRP
ESA TO : Mr. Chris Taylor - Data Systems Division
The standardisation of the flight avionics infrastructure is progressing on many different fronts:
· The SAVOIR initiative has developed a reference avionics architecture identifying individual building blocks
· The CCSDS SOIS area has made significant progress in standardising the avionics communication services with many standards already under publication.
· The ECSS has developed a number of data link protocols and device interface standards for avionics interconnection.
The objective of the Electronic Data Sheets and Device Virtualisation activity was to demonstrate the use of electronic data sheets (EDS) in the above context to replace or supplement existing paper ICDs, and to employ the results to interfacing onboard sensors and actuators.
We present the results of the following activities to meet this objective
· Evaluate the general requirements on EDS technology, taking account of the reference and communication architectures including the relationship between the central processor and remote terminal units.
· Analyse a series of paper based data sheets for a number of devices and define the required contents of an EDS for each of them.
· Produce a draft XML schema and CCSDS specification for an EDS to define the functional and data link interface of onboard devices.
· Demonstrate the feasibility and advantages of using EDS to specify the device-specific components of SOIS DVS and DAS via a practical demonstration based on actual data sheets using the RASTA test facility.
· Provide feedback to the CCSDS SOIS area on progression to standardisation of EDS.
