Search and Rescue Aid Tool (SARAT)

News: The Indian National Centre for Ocean Information Services (INCOIS), under the Ministry of Earth Sciences, has recently upgraded its Search and Rescue Aid Tool (SARAT).

About Search and Rescue Aid Tool (SARAT)

• It was launched in 2016 by the Indian National Centre for Ocean Information Services (INCOIS) under the Make in India program.
• It facilitates search and rescue operations at sea by quickly locating individuals or vessels in distress.
• Key Features and Working:
  • Advanced Modeling: The tool uses ensemble modeling to account for uncertainties in the initial location and time of the missing object. Movements are tracked based on ocean currents and winds.
  • Technology Backbone: It relies on high-resolution Regional Ocean Modelling System (ROMS) data, operationally run on High-Performance Computers at INCOIS.
  • Customizable Options: Users can choose from up to 60 types of missing objects (categorized by shape and buoyancy) and pinpoint the last known location using an interactive map or input distance and direction.
  • Results and Communication: The tool generates an interactive map showing the probable search area, with results also sent via text and email. Localized languages are supported to aid fishermen in distress.
• Improvements in SARAT Version 2:
  • The starting position for the search is now accurately set to the last known location.
  • Enhanced visualizations include color-coded search regions, improved clarity of probable search areas, and a marker to identify the last known position.
