Search & Rescue Problem
   Create a SAR case when alerted
   Gather data, estimate uncertainties
   Use model to determine search area
   Estimate resource availability and capability
   Plan the next search
   Promulgate the search plan
   Perform the search plan
   Evaluate the completed search
   Repeat above until survivors are found and
    rescued
USCG Transition
   SARTools
     – Joint Automated Worksheet (JAWS)
         Near-shore search planning
         Based on 1950’s paper & pencil technology
     – Computer Assisted Search Planning (CASP)
         Offshore search planning
         Based on 1970’s technology
   SAROPS
     – Technologically current software tool
     – Near-shore and offshore search planning
     – Extensible to land-based search planning

SAROPS Goals

     To provide fast, simple Search & Rescue
      predictions
     Minimise data entry and potential for error
     Automate data linkages
      – Environmental Data Inputs
      – Search Action Plan Outputs
     Simple Visualization of Results
SAROPS Scenario Types
  – Voyage scenario where object can pass through or loiter in a
      number of locations (positions or areas) using any combination
      of great circle and rhumb line routes
  –   Initial Position (with bivariate normal uncertainty) and time
      uncertainty for an event plus an offset for initial location and
      time of distress
  –   Positions obtained from COSPAS-SARSAT, other GMDSS
  –   Lines of Bearing (from Radio Direction Finding, Flare Sightings,
      Loran, and others)
  –   Areas defined by polygons
  –   “Reverse Drift” scenarios
  –   Scenarios may be “weighted”
SAROPS Components

   Graphical User Interface/ (GUI)
   Environmental Data Server
    (EDS)
   Simulator (SIM)
GUI Requirements

   Deployable on ESRI® GIS mapping engine (C/JMTK)
   Wizard based interface
   Minimize keystrokes
   Chart support (vector/raster)
   Display environmental data
   Animated display capabilities
   Display recommended search plans/areas/patterns
   Display probability maps (by scenario, object type or
    combined)
   Reporting

SIM Requirements
   “Monte Carlo” (particle filter) simulation
     – Simulate pre-distress motion & fixed hazards
     – Simulate distress incidents and outcomes
     – Simulate post-distress motion (drift)
     – Calculate near-optimal search plan (max POS)
     – Simulate simultaneous SRU and Search Object
       motion (use POD vs. range at CPA on each leg)
     – Compute cumulative POS
     – Account for effects of previous unsuccessful
       searching when recommending subsequent
       search plans.
Future SIM Enhancements
   Multiple-rectangle Optimal Search Plans
   Optimal Survivor Search
    – Canadian Cold Environment Survival Model
   Moving Hazards (Storms, Fronts, etc.)
   Improved Detection (sensor) Modeling
EDS Requirements

   Water current data
   Wind data
   Other (visibility, cloud cover, sea state, etc)
   Accommodate scales/resolutions automatically
   Global land database
   Expansion of data products and uses
