ESA Ground Station Network

Remote Monitor and Control Characteristics
  • All equipment in a ground station is connected
    via a layered architecture to a Station Computer.
    Latter is remotely controlled from ESOC.
  • Configuration of station equipment (gt 15000
    parameters) via predefined macrocommands (Jobs)
  • Sets of Jobs specific for each mission
  • (For most stations) job execution is triggered
    manually by Operators who follow a Sequence of
    Events
  • Routine supports manual remote operations from
    ESOC, stations unmanned
  • Critical support periods (launch) local central
    operations under voice control from ESOC,
    stations manned

Automated Station Operations, Current
  • Remote operations of ESAs Kiruna ground station
    (frequent short duration passes) are fully
    automated.
  • Full Sequence of Events is executed via time tag
    driven Jobs.
  • Time tags are referenced to AOS/LOS
  • Remote operator at ESOC supervises pass.
    Intervention only in case of problems.
  • Automation in use since 1991. Station was
    dedicated to earth observation missions which
    generated the job time line.

9
Drivers for change
  • Cost pressure on ESTRACK
  • Higher utilisation of existing installations and
    personnel
  • Reducing own facilities and more procurement of
    services from partners. Interoperability.
  • Higher degree of sharing ? multimission
    facilities and teams
  • Changing customer charcateristics
  • Higher on-board autonomy with reduced operator
    staffing on ground
  • Fewer ground contact periods but with higher
    reliabilty
  • Very elastic support requirements  n hours of
    tracking per week from any ESTRACK station with a
    minimum duration of 2 hrs
  • Automated mission operations
  • Technological advances in ground segment
    technology
  • Increased complexity and diversity (deep space)
    of ESTRACK installations
  • Availability of reliable wide band communications
    at reasonable cost
  • Increase of COTS elements in ground station.

10
Trend towards Automation
Merging of automated planning/scheduling and
operations execution
Automation on network level
Automated remote operations for multi mission
stations incl. deep space
Automation of stations that are mission dedicated
Remote operations
Local, central operations
11
ESTRACK Management and Scheduling System (EMS)
12
Automated Station Operations, Ongoing
  • Automated operations at Cebreros for Venus
    Express are implemented. New Norcia in
    preparation. Time lines are generated by mission
    planning system.
  • Automation for Mars Express station operations is
    being implemented. Time lines generated by
    ESTRACK (SCHEDITOR).
  • Time line execution uses existing feature of STC.
  • Results are very positive.

13
Conclusion
  • Remote operation of ESTRACK stations is safe and
    mature.
  • Automated remote operations of mission dedicated
    stations is succesfully implemented.
  • Automated remote operations are being introduced
    for the entirety of the ESA stations.
  • ESTRACK Management and Scheduling System (EMS)
    will enable automated operations on network
    level.
  • EMS will enable automatic interaction between
    planning/scheduling and real time operations.
