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 1950s paper pencil technology
- Computer Assisted Search Planning (CASP)
- Offshore search planning
- Based on 1970s 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
9
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
10
SAROPS Components
- Graphical User Interface/ (GUI)
- Environmental Data Server (EDS)
- Simulator (SIM)
11
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.
15
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
16
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
