  1. Common and IndividualSituation Awarenessfrom a Technical Point of View Klas Wallenius

  2. Outline • Situation Awareness • WASP • Incl. demonstration • Future development of Situation Picture

  3. Situation Awareness What you need to know when making decisions • The Task • States of Resources • Entities that can be affected by your and other actors decisions • Environment • Entities that cannot be affected by decisions • Actor’s possibilities to act • The relations between entities • How much you know and could know • Knowledge is a set of hypotheses • “Information Awareness” - Precision, quality, and utility

  4. Mental Situation Awareness Mental SA • SA is mental and could be achieved without artifacts

  5. Technical Support for C2 Mental SA Technical SA MissionManagement The Task SituationPicture States of Resources Environment SimulationModels Ability to act

  11. Common SA ServicesPhysically Distributed

  12. Common SA ServicesPhysically Distributed Requires means to Keep info consistent Keep robust to congestion and bandwidth fluctuations Keep track of resulting quality Select info relevant to the task at hand

  13. Wasp – The Wide Area Situation Picture WCU WCU WCU WCU • Provides Situation Picture regarding moving targets • A distributed and non-hierarchical infrastructure • Based on commercial network technology (Internet) • Encapsulated software for effortless integration - The WASP Correlator Unit (WCU) • Scalable, robust and possible to reconfigure on the fly. Wide AreaNetwork Superior Local Tracks GlobalTracks WCU SensorFusion Presen-tation

  14. WASP Features • Unique global target numbering • No hierarchical verification of the situation picture • On-line estimation of data quality • Bandwidth control • Encapsulated and distributed functionality • Data selection with respect to geographical areas and data quality WCU WCU Wide AreaNetwork WCU WCU WCU

  15. Future Development of Situation Picture • Include other kinds of objects • Make relevant also for higher command levels • Hierachical Aggregation • Projects or activities rather than objects • Non map-oriented entities • Non map-oriented interaction

  16. Future Development of Situation Picture • Include also the future and the past • Save Situation Picture continously • Integrate with planning and simulation • Information Awareness • Introduce general management of uncertainties • PDFs of hypothesises • Calculate relevant info

  17. The End
