SAGAR SAMPARK - DGNSS 

Sagar Sampark -Differential Global Navigation Satellite System ( 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.

Sagar Sampark – Differential Global Navigation Satellite System (DGNSS)’ is launched at 06 locations under DGLL (Directorate General of Lighthouses and Lightships), will definitely enhance the capability of the DGLL in the field of the Radio Aids to Marine Navigation.’

After recapitalization with multiple satellite constellations like GPS and Global Navigation Satellite System (GLONASS), DGNSS further increases the availability and redundancy as per International standards and helps the mariners to improve their positioning within 5 meters.

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.

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)’.
