Focus: GS II: Government Policies and Interventions

Why in News?

Recently, the Union Minister of Ports, Shipping and Waterways inaugurated the indigenous Differential Global Navigation Satellite System (DGNSS) ‘SAGAR SAMPARK.

About SAGAR SAMPARK:

  • SAGAR SAMPARK is an indigenous Differential Global Navigation Satellite System (DGNSS).

Differential Global Navigation Satellite System (DGNSS):

  • DGNSS is a terrestrial-based enhancement system that corrects errors and inaccuracies in the Global Navigation Satellite System (GNSS), enabling more accurate positioning information.
  • SAGAR SAMPARK serves as a DGNSS.

Transmitting Corrections:

  • SAGAR SAMPARK is capable of transmitting corrections of GPS and GLONASS, two widely used global navigation satellite systems.

Assisting Director General of Lighthouses and Lightships (DGLL):

  • SAGAR SAMPARK is implemented at six locations to support the Director General of Lighthouses and Lightships in providing radio aids to ships for marine navigation.
Benefits for Marine Navigation:
  • The system offers accurate information to ships, ensuring safe navigation and reducing the risk of collisions, groundings, and accidents in port and harbor areas.
  • It enables the safe and efficient movement of vessels.
Improved GPS Positioning Accuracy:
  • SAGAR SAMPARK significantly enhances the accuracy of GPS positioning.
  • It reduces errors caused by atmospheric inferences, satellite clock drift, and other factors.
  • The system has improved the error correction accuracy from 5 to 10 meters to less than 5 meters for 100 Nautical Miles (NM) from Indian coastlines.
