ISRO Unveils Advanced Distress Alert Transmitter For Fishermen

 

The Indian Space Research Organisation (ISRO) has been at the forefront of technological innovation, contributing significantly to various fields. One such noteworthy development is the second-generation ‘Distress Alert Transmitter’ (DAT-SG), a remarkable advancement in satellite communication and navigation capabilities. Operational since 2010, the DAT-SG has become a crucial tool for fishermen at sea, allowing them to send emergency messages and receive real-time acknowledgments.

Evolution of Distress Alert Transmitter (DAT)

The journey of the Distress Alert Transmitter began with its initial version in 2010. Designed to facilitate communication during emergencies at sea, the DAT quickly became an integral part of maritime safety. With over 20,000 units currently in use, it has proven to be a reliable and effective tool for fishermen in distress.

Satellite Communication and Navigation Capabilities

The DAT-SG incorporates advanced satellite communication and navigation features, leveraging the latest technological developments. Through a communication satellite, fishermen can send distress signals from their boats, initiating a real-time connection with a central control station – the Indian Mission Control Centre (INMCC). This upgraded version of DAT ensures a more robust and efficient communication process.

Real-Time Acknowledgments

One of the key enhancements in DAT-SG is the ability to provide real-time acknowledgments to fishermen activating distress alerts. This feature not only confirms the receipt of the emergency message but also reassures the fishermen that their distress signals have been received and are being addressed.

Decoding Identity and Location

When distress signals reach the INMCC, the alert signals are decoded to determine the identity and precise location of the fishing boat. This crucial information is then forwarded to Maritime Rescue Co-ordination Centres (MRCCs) under the Indian Coast Guard (ICG). The seamless flow of information allows for swift and effective Search and Rescue operations to be undertaken.

Bi-Directional Communication

DAT-SG goes beyond its predecessor by enabling bi-directional communication. In addition to transmitting distress signals, the DAT-SG has the capability to receive messages from the control centre. This two-way communication further enhances the effectiveness of the system, ensuring a more comprehensive response to emergency situations.

Role in Maritime Safety

The DAT-SG plays a pivotal role in enhancing maritime safety by providing an advanced and reliable communication platform for fishermen. With its improved features and capabilities, it contributes significantly to minimizing response time during emergencies, ultimately saving lives at sea.
