Electronic data Sheets While the objective of harmonising the onboard services and protocols remains a clear SOIS goal it is recognised that there will always be a need for variability In support of this the concept of Electronic Data Sheets has been developed in SOIS The idea is not complete new and was used in the original AFRL plug and Play development as well as terrestrial technology such as Canbus An EDS may be used to document the specification of an object (s/w or h/w component) in machine readable format The EDS may then be used to automate many of the spacecraft integration tasks typically performed manually today.
