Answer: ISRO
Notes: ISRO has developed a second-generation Distress Alert Transmitter (DAT) that enhances safety for fishermen at sea. Operational since 2010, over 20,000 DATs are in use. The technology allows fishermen to send emergency messages with real-time acknowledgments through satellite communication. The DAT-SG, an improved version, utilizes advanced capabilities and features. Messages decoded at the Indian Mission Control Centre help Maritime Rescue Co-ordination Centres locate distressed boats for timely Search and Rescue operations, reassuring fishermen of impending assistance.
