Overview of Space Communication Cross Support Architecture
April 2013Takahiro Yamada (JAXA/ISAS)
1
Purpose of the Architecture• Space Communications Cross Support Architecture
– To be used as a common framework when CCSDS Agencies • provide and use space communications cross support services• develop systems that provide interoperable space
communications cross support services
2
Documents• Space Communications Cross Support Architecture Description Document
– Green Book– Provides descriptive information
• Space Communications Cross Support Architecture Requirements Document – Magenta Book– Provides the normative specifications and definitions
3
System Elements• Cross Support Service Element (CSSE)
– a physical element that is involved in providing one or more space communications cross support services, possibly together with some other CSSEs
• User Element (UE)– a physical element that is involved in using one or more space
communications cross support services provided by one or more CSSEs
• Cross Support Service System (CSSS)– a set of CSSEs or UEs that are managed by a single authority with a
single set of management policies
