Space Situational Awareness

• Space Situational Awareness
• Briefing for SWWT topic groups
• Mike Hapgood
• Chair, ESA Space Weather Working Team

BACKGROUND

• Space Situation Awareness is a concept that
  reflects our increasing dependence on space
  systems telecom, navigation, surveillance, etc.
  
• Originates from US military but civilian
  systems are equally vulnerable.
• Europe needs to develop both policy and capacity.
  
• ESA developing proposal for 2008 MC. This is seen
  to have three axes
• Survey, Tracking,
• Imaging
• Space weather (space environment monitoring)

Recent progress

• SWWT /SB convened meeting in Paris, 3 October.
• Attended by reps from many ESA Member States
• Key outputs
• SWWT Chair to join ESA SSA User Group (Paris, 21
  November)
• AG/MH to identify SpW target areas for SSA and
  develop scenarios for SpW services (central node?
  competence centres?)
• Solicit input from SB members on national data
  policies and how these could impact a Space
  Weather element of a SSA proposal.
• Explore interaction with LOFAR project (TEC data?)

4
Work in progress

• Mapping SpW measurement requirements to SSA
  relevance see following slides
• Mapping SWENET services to SSA relevance
• Scenarios for SSA services SWENET, CSDS
• Explore national data policies?
• LOFAR phase calibration for radio astronomy
• source of TEC data?
• user of ionospheric models?

SpW measurements for SSA

• Mapping of space weather measurement requirements
  to three proposed levels of SSA relevance.
• The requirements derived from ESA space weather
  feasibility studies led by Alcatel and RAL in
  2000/1
• space-based measurements - from recent RAL
  consolidation of both 2000/1 studies
• ground-based measurements - from RAL study
• Both have traceability to the common user
  requirements developed by RAL and Alcatel
