Union Minister of Ports, Shipping and Waterways, Shri Sarbananda Sonowal inaugurated the indigenous Differential Global Navigation Satellite System (DGNSS) ‘SAGAR SAMPARK’.
About DGNSS
- DGNSS is a terrestrial based enhancement system which corrects the errors and inaccuracies in the Global Navigation Satellite System (GNSS) allowing for more accurate positioning information.
- ‘DGNSS is an important Radio Aid to Navigation towards fulfillment of international obligations of International Maritime Organisation (IMO), Safety of Life at Sea (SOLAS) and International Association of Marine Aids to Navigation and Lighthouse Authorities (IALA)’.
- The DGNSS service will help mariners in safe navigation and will reduce the risk of collisions, groundings, and accidents in the port and harbour areas. This will lead to safe & efficient movement of vessels.
- DGNSS further increases the availability and redundancy as per International standards and helps the mariners to improve their positioning within 5 meters.
- The DGNSS significantly improves the accuracy of GPS positioning, reducing errors caused by the atmospheric inferences, satellite clock drift and other factors.
- This is achieved with the help of modern state of art technology receivers and latest software. The error correction accuracy has been improved from 5 to 10 meters to less than 5 meters for 100 Nautical Miles from Indian coastlines.
