SARAT Version 2

February 7, 2025

The Government of India has recently upgraded its Search and Rescue Aid Tool (SARAT) to enhance operational efficiency for search and rescue agencies. The latest version, SARAT version 2, aims to provide faster response times and higher success rates in search-and-rescue operations, particularly in the Indian Ocean region.

Key Improvements in SARAT Version 2

The latest version introduces several enhancements. The computation of probable search areas is now anchored to the Last Known Position (LKP) of the object. This shift allows for more accurate search area definitions. Previously, the search area was determined based on the point with the minimum longitude, which was less precise.

Enhanced Data Visualization and Exportability

SARAT version 2 now offers search areas in a digital format. This feature enables seamless integration with rescue planning maps. The tool includes visualisation of individual and mean particle trajectories. It also presents colour-coded search regions and a marker for the LKP. These enhancements improve clarity and interpretation of visual outputs.

Training and Capacity Building Initiatives

To ensure effective use of the updated tool, the Indian National Centre for Ocean Information Services (INCOIS) has implemented targeted training initiatives. A national workshop was organised to train personnel from the Indian Coast Guard (ICG) and the Airports Authority of India (AAI). Over 60 officers participated, gaining essential skills for utilising SARAT effectively in operations.

Feedback and Continuous Improvement

INCOIS encourages feedback from stakeholders during SAR workshops. This feedback is vital for refining and enhancing the SARAT tool. Regular lectures and demonstrations are conducted to keep personnel updated on operational aspects. Such initiatives contribute to improved search-and-rescue outcomes.

Future Plans for SARAT Enhancements

The Ministry of Earth Sciences has plans to further increase the accuracy of SARAT. This will be achieved by improving surface current and wind predictions. Greater volumes of ocean observations will be assimilated into ocean circulation models. High-Frequency (HF) radar measurements will also be utilised to enhance the accuracy of coastal surface currents.
