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


  • SAGAR SAMPARK is an indigenous Differential Global Navigation Satellite System (DGNSS) that enhances maritime navigation by correcting errors and inaccuracies in the Global Navigation Satellite System (GNSS), providing more precise positioning information. Its introduction brings significant benefits to vessel movement in ports and harbors, ensuring safety and efficiency.
  • Features:
    1. SAGAR SAMPARK assists mariners in navigating safely, reducing the risks of collisions, groundings, and accidents at sea.
    2. The DGNSS greatly enhances the accuracy of GPS positioning by mitigating errors caused by atmospheric influences, satellite clock drift, and other factors.
    3. It can transmit corrections for GPS and GLONASS.
    4. It supports the Director General of Lighthouses and Lightships (DGLL) in providing radio aids to ships for marine navigation.
    5. SAGAR SAMPARK fulfills the international obligations set by organizations such as the International Maritime Organization (IMO), Safety of Life at Sea (SOLAS), and the International Association of Marine Aids to Navigation and Lighthouse Authorities (IALA).
  • Conclusion:
    1. SAGAR SAMPARK is a remarkable indigenous DGNSS system that improves marine navigation and GPS positioning accuracy.
    2. Its capabilities include transmitting corrections for GPS and GLONASS, supporting the DGLL, and ensuring safe vessel movement.
    3. It revolutionizes maritime navigation with its indigenous DGNSS capabilities, providing enhanced safety, improved accuracy, redundancy, precise positioning, and compliance with international standards.
