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
