collapse CROSS SUPPORT SERVICES AREA

​The CSS area addresses how the services of an agency’s TTC network are made available to another agency’s mission spacecraft. This includes addressing data transfer services and their management. The data transfer services involve both space link (to/from TTC network ground station to mission spacecraft) and terrestrial link (to/from TTC network ground station to the mission ground data system). The space link data transfer encoding/protocol schemes are subject to the SLS area and are not defined by the CSS area. The terrestrial data transfer services, with regard to transfer mission data and observations such as ground station tracking data, are addressed by the CSS area. The management of both the space link and data transfer services is also addressed by the CSS area. Proper definitions of the services and management of these services depends on a reference architecture definition and also agreed, internationally recognized terms for the functional components of this architecture. The terrestrial data transfer services and management data format definitions may be inc​​orporated into mission operations end-to-end recommendations of the MOIMS area. The strategic goals of the CSS area are presented below.​
