The Ministry of Ports, Shipping and Waterways is committed towards innovation, building best infrastructure, and strengthening the Indian Maritime sector. On 12 July to further the digital initiative in maritime sector the Union Minister of Ports, Shipping and Waterways, Shri Sarbananda Sonowal inaugurated the indigenous Differential Global Navigation Satellite System (DGNSS) ‘SAGAR SAMPARK’ in the presence of Shri Shripad Y. Naik, the Minister of State of Ports, Shipping and Waterways; 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.

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.

The latest DGNSS system is now able to transmit corrections of GPS and GLONASS. 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.
