GEMINI System

Explanation :

• GEMINI or GAGAN Enabled Mariner’s Instrument for Navigation and Information is based on GAGAN (GPS-Aided Geo Augmented Navigation) satellite system developed by the Indian National Centre for Ocean Information Services (INCOIS), Indian Space Research Organization (ISRO) and Airports Authority of India (AAI).
• The GAGAN satellite system consists of three geosynchronous satellites namely the GSAT-8, GSAT-10 and GSAT-15 and these three cover the entire Indian Ocean region constantly.
• However, the device only allows one-way communication — it can’t be used by fishermen to make calls, for instance.

Benefits

• Mobile phone frequencies cannot be accessed 10-12 km beyond the coast and with GEMINI this range can increase to 300 nautical miles, allowing better communication.
• Through the new system, all the key alerts and messages will be send directly to the fishermen venturing in deep sea, providing them the accurate information about any disaster, thus help in saving precious human resources.
