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.
