GEMINI system to aid fishermen
To avoid communication blackouts that led to 20 fishermen going missing in the aftermath of Cyclone Okchi in 2017, a slew of government departments, research agencies and private companies have developed GEMINI.
What is GEMINI?
- It is a portable receiver linked to ISRO-satellites, that is ‘fail-proof’ and warn fishermen of danger.
- The Indian National Centre for Ocean Information Services (INCOIS), a Hyderabad institute collaborated with Accord with a private company to develop a box-shaped receiver that has an antenna and in-built battery that can last three to four days.
- GEMINI works on GAGAN, developed by ISRO and the Airports Authority of India and is an India-made global positioning system and relies on the positioning system by ISRO’s GSAT satellites.
- The satellite-based communication is the only suitable solution for the dissemination of such emergency information and affordable satellite-based communication system should be made part of the dissemination chain to deal with cyclones, high waves and tsunamis.
- With this device, fishermen outside the signal range of their phone companies can also access warnings and alerts.
Limitation of the device:
- The device only allows one-way communication it can’t be used by fishermen to make calls.
- The device could be more easily accessible to India’s 900,000 fishermen if the chips powering mobile phones were able to receive signals from the GAGAN system.
Know about GAGAN(GPS-aided GEO augmented navigation)
The GPS-aided GEO augmented navigation (GAGAN) is an implementation of a regional satellite-based augmentation system (SBAS). It is the first step towards the introduction of modern communication, navigation and surveillance/Air Traffic Management system over Indian airspace.
