Explanation: Nabhmitra’, a device developed by ISRO-Space Applications Centre (Ahmedabad) for the safety of fishermen, was successfully tested at Neendakara.

• The satellite-based communication system enables two-way messaging services from and to the sea.
• While weather and cyclone warnings will be communicated in the local language, the boats can also send distress messages to the authorities.
• In emergency situations like capsizing and fire, fishers can press a button on the device and get in touch with the control centre.
• While the control centre will receive the alert including the location of the boat, the crew on the boat will get a response message from the control centre.
