High Level Goal
  • Standardisation of interfaces for Spacecraft MC
  • Reduced cost of Flight Components andGround
    Segment Infrastructure
  • Enable plug and play Architecture with
    components from different Agencies, Systems and
    Suppliers
  • Enable Mission Economies through
  • Interoperability with partner systems and
    infrastructure
  • Risk Reduction through re-use of systems and
    operational concepts increased reliability
  • Facilitation of Generic Software Infrastructure
    (On-board and Ground-based)
  • Application of a common MC Approach throughout
    all mission phases
  • Application of a common MC Approach to other
    domains (Ground Stations, Control and Test
    Centres, etc.)

4
Scope
  • Operational concept
  • definition of an operational concept that covers
    a set of standard operations activities related
    to the monitoring and control of both ground and
    space segments.
  • Set of Application Services
  • definition of an extensible set of services to
    support the operational concept together with its
    information model and behaviours. This includes
    (non exhaustively) ground systems such as
    Automatic Command and Control, Data Product
    Management, Flight Dynamics, Mission Planning,
    Automation, and Performance Evaluation.
  • Application-layer information
  • definition of the standard information set to be
    exchanged for SMC purposes.

5
Objectives
  • Define a common SMC operational concept
  • Define a reference on-board and on ground
    architecture in close coordination with other
    CCSDS groups (e.g. SOIS, SEA)
  • Identify standard Mission Control System
    interfaces with MC components
  • with remote software management
  • with Mission Planning System
  • with the Flight Dynamics System
  • Define a standard approach to service
    specification
  • Define application-level service access points
  • Define SMC Common protocol layer

6
Schedule
  • Dec 03 Formation of WG (1st meeting)
  • Apr 04 SMC Service Framework (WB draft 0.4)
  • Dec 04 Green Book
  • advanced concept papers on
  • Common SMC Protocol Service
  • Core SMC Application Service

7
Service Based Architecture
  • Defines the interface as a contract
  • Consumer (client) unaware of providers
    implementation
  • Popular with distributed and web based systems

Space System Context
  • Defines reference system
  • Defines operational context
  • Outlines clients of the system
  • Outlines operational areas of the system

13
Functional View
  • Uses RASDS methodology
  • Defines areas of functionality
  • Taken from the operational context
  • Defines interactions between functional areas
  • Leads to service identification

14
Modularity and Flexibility
15
Information flow
  • Key task is to identify the information objects
  • Elaboration of the services will identify these
    objects
  • Will also define their attributes

Summary
  • Work done
  • drafted CCSDS White Book
  • analysed operational context
  • identified services
  • used layered architecture
  • Future work
  • CCSDS Green Book
  • CCSDS standard specifications of each service
