What is Sagar Sampark?
Sagar Sampark is an indigenously developed Differential Global Navigation Satellite System (DGNSS). It's an enhancement system designed to correct errors and inaccuracies in the Global Navigation Satellite System (GNSS), providing more precise positioning information.
How does the Global Navigation Satellite System (GNSS) work?
GNSS is a space-based positioning, navigation, and time distribution system. It involves a constellation of satellites that transmit positioning and timing data globally. GNSS receivers use this data to determine precise locations.
What is the purpose of Differential GNSS (DGNSS)?
DGNSS aims to improve the accuracy of GNSS by providing real-time corrections and integrity monitoring. It involves reference stations at known locations that offer corrections for GNSS signals, enhancing shore-to-ship services.
How does Sagar Sampark-DGNSS enhance marine navigation?
Sagar Sampark-DGNSS reduces the risk of collisions, groundings, and accidents in port and harbour areas by providing mariners with accurate navigation information. It facilitates safe and efficient vessel movement and meets international obligations of organizations like IMO, SOLAS, and IALA.
What are the benefits of DGNSS over standard GNSS?
DGNSS significantly improves GPS positioning accuracy, reducing errors caused by atmospheric interferences, satellite clock drift, and other factors. The error correction accuracy with DGNSS is enhanced from 5-10 meters to less than 5 meters within 100 Nautical Miles of the Indian coastline.
What role does the Directorate General of Lighthouses and Lightships (DGLL) play?
The DGLL is responsible for establishing and maintaining Aids to Marine Navigation along India's coastline. It operates under the Marine Aids to Navigation Act, 2021, replacing the Lighthouse Act, 1927, and provides General Aids to Marine Navigation.
What is the International Association of Marine Aids to Navigation and Lighthouse Authorities (IALA)?
IALA is an association that brings together organizations responsible for Aids to Marine Navigation. Headquartered in France, it encourages the improvement of marine navigation aids. IALA promotes cooperation among member countries for the development of navigational systems to enhance maritime safety. The DGLL represents India in IALA.
SRIRAM’s Insight:
Sagar Sampark represents a significant advancement in marine navigation technology. By improving the accuracy of GPS positioning and reducing navigational errors, it plays a crucial role in ensuring the safety and efficiency of maritime operations around the Indian coastline. The initiative aligns with international standards and contributes to India's capability in the global maritime sector.
