Indian Space Research Organisation (ISRO) has developed an improvised Distress Alert Transmitter (DAT).
- It has been developed for the fishermen at sea to send emergency messages from fishing boats.
- The first version of DAT has been operational since 2010, using which messages were sent through a communication satellite and received at a central control station (INMCC: Indian Mission Control Centre).
- The extracted information is then forwarded to Maritime Rescue Coordination Centres (MRCCs) under the Indian Coast Guard (ICG).
- The central control centre (INMCC) has a web based network management system called Sagarmitra which maintains a database of registered DAT-SGs and helps MRCCs to access the information about boat, coordinate the boat in distress in real time.
