Space Situational Awareness Briefing for SWWT Groups

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

2. 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)

3. 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?

5. 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
