What is the News?
The Union Minister of Ports, Shipping and Waterways has inaugurated the indigenous Differential Global Navigation Satellite System (DGNSS) called ‘SAGAR SAMPARK’.
What is Sagar Sampark?
Sagar Sampark is a terrestrial based enhancement system that corrects the errors and inaccuracies in the Global Navigation Satellite System (GNSS) and provides more accurate positioning information.
Features: Sagar Sampark is able to transmit corrections for both GPS and Global Navigation Satellite System (GLONASS).
– It improves the accuracy of GPS positioning by reducing errors caused by atmospheric inferences, satellite clock drift and other factors.
– The error correction accuracy has been improved from 5 to 10 meters to less than 5 meters for 100 Nautical Miles from Indian coastlines.
Significance: Sagar Sampark will help mariners in safe navigation and will reduce the risk of collisions, groundings, and accidents in the port and harbour areas.This will lead to the safe & efficient movement of vessels.
