INCOIS launches satellite-based advisory service for deep sea fishermen

The Indian National Centre for Ocean Information Services (INCOIS) and Airport Authority of India launched a new system that expands the scope for disseminating alerts and other messages to fishermen who go for multi-day fishing and other such activities deep inside the seas.

The new service was launched by Dr Harsh Vardhan, the minister for science and technology and earth sciences At present, fishermen get advisories, forecasts and early warnings through a wide range of dissemination mechanisms such as Potential Fishing Zones (PFZ) advisories, ocean state forecasts, high wave alerts, and tsunami and storm surge early warning services. But these messages can be transmitted only up to a distance of 10 to 12 km from the coast. Such information needs to be conveyed even to those venturing into the sea beyond 50 nautical miles (90 km) and further.

Gap in Communication during cyclone
The gap in communication was severely felt during the Ockhi cyclone of November-December 2017, when fishermen who had gone out for deep sea fishing before the onset of the cyclone could not be informed the impending storm. This resulted in loss of life, serious injuries to those rescued and severe damages to fishing boats and fishing gear.

New GPS aided system
The new system is designed to overcome the problem. It consists of a specially designed device and a mobile application. It works by using the communication opportunity provided by GAGAN (GPS-Aided Geo Augmented Navigation) satellite system of the Indian Space Research Organization (ISRO) and Airports Authority of India. GAGAN consists of three geosynchronous satellites - GSAT-8, GSAT-10 and GSAT-15 and its footprints cover the entire Indian Ocean round the clock.

About Gagan device
Alerts and other messages would be sent through GAGAN and the device would receive and transfer it to a mobile phone through blue tooth communication. The mobile application would decode and display the information. It is enabled to do so in nine languages. The technology for the device has been transferred to a Bengaluru-based company, Acord. The device has been named GEMINI (GAGAN Enabled Marine) Instrument for Navigation and Information).

Potential Fishing Zone (PFZ)
The minister also launched an improved version of the Potential Fishing Zone (PFZ) forecasts developed by INCOIS. The new version will provide advisories three days in advance. The forecasts are generated using the modern tools of numerical models and thus are expected to help provided the advisories even when skies are overcast.
