Overview of Space Communication Cross Support Architecture April 2013 Takahiro 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 4
