The Union Minister of Earth Sciences has recently launched the Gagan Enabled Mariner’s Instrument for Navigation and Information (GEMINI) device.

The device is developed for effective dissemination of emergency information and communication on Ocean States Forecast and mapping of Potential Fishing Zones (PFZ) to fishermen.

Ocean States Forecast provides the accurate state of the ocean that includes the forecasts related to winds, waves, ocean currents, water temperature, etc.

PFZ provide information about the probable locations of fish aggregation in the seas to the fishermen, while

GEMINI is a portable receiver that is linked to ISRO-satellites. With this device, the fishermen outside the signal range of their phone companies (i.e. 10-12 km) can also access warnings and alerts, as the device can send signals up to 300 nautical miles.

It will facilitate satellite-based communication that will be highly useful while dealing with cyclones, high waves, and tsunamis.Indian National Centre for Ocean Information Services (INCOIS) in collaboration with the Airports Authority of India (AAI) utilized the GAGAN (GPS Aided Geo Augmented Navigation) satellite while developing the GEMINI device.
